New York Launches First COVID-19 Vaccination, Test Result App For Event Attendance : Co... - 0 views

  • Cuomo announced Friday that the state's health status certification, called the Excelsior Pass, will help New Yorkers voluntarily share vaccination and COVID-19 negative statuses with entertainment venues and other businesses to put the state state's economy back on track.
  • New Yorkers can always show alternate proof of vaccination or testing, like another mobile application or paper form, directly at a business or venue.
  • The pass could see New York's Broadway theaters, concert venues and sports arenas fill seats again after closures that started in March of 2020.

  • Airlines and technology companies have been working on developing technology to do so, but New York's is the first pass being made widely available to residents.
  • The idea is similar to mobile airline boarding passes: they can be printed or stored on smartphones, and participating businesses and venues can use a companion app to confirm patrons' health status.
  • rather than boost the economy and encourage vaccination, efforts like the Excelsior Pass could wind up further spread of variants. It's also still not clear that vaccinated people cannot spread the virus to people who have not been vaccinated.
  • Some worry that the passes might encourage fraud and increase the spread of the virus by people who claim to be vaccinated or COVID-19 negative but aren't.

Why time seems to speed up as we get older - Vox - 0 views

  • As part of a lifelong experiment on circadian rhythms, Sothern, now 69, is trying to confirm or reject a widely held belief: Many people feel that time flies by more quickly as they age.
  • So far, Sothern's results are inconclusive
  • "I'm tending now to overestimate the minute more than I used to," he tells me. But then again, he had detected a similar pattern — more overestimates — in the 1990s, only to have his estimates fall in the 2000s. "Time estimation isn't a perfect science," he says.
  • ...17 more annotations...
  • There's very little scientific evidence to suggest our perception of time changes as we age. And yet, we consistently report that the past felt longer — that time is flying by faster as we age. What's going on?
  • Scientists can look at time estimation, or our ability to estimate how long a minute passes, compared with a clock. (This is what Sothern is doing.) They can also look at time awareness, or the broad feeling that time is moving quickly or slowly. Finally there's time perspective, the sense of a past, present, and future as constructed by our memories.
  • What researchers have found out is that while time estimation and time awareness don't change much as we age, time perspective does. In other words: Our memories create the illusion time is accelerating.
  • There weren't many differences between the old and the young. "[C]hronological age showed no systematic influence on the perception of these brief intervals of time up," the authors wrote. (That said, the researchers did find that males overestimate time while females underestimate it, perhaps due to having slightly different circadian clocks and therefore slightly different metabolic rates
  • Here, too, age seemed not to matter. Older people didn't seem to be aware of time passing any faster than younger people. The only question that yielded a statistically significant difference was, "How fast did the last decade pass?" Even there, the reported differences were tiny, and the effect appeared to plateau around age 50.
  • psychologists William Friedman and Steve Janssen found scant evidence that the subjective experience of time speeds up with age. They write in their 2009 paper, "We can concluded that when adults report on their general impressions of the speed of time, age differences are very small."
  • One possibility is that participants were simply biased by the (incorrect) conventional wisdom — they reported their later years as flying by more quickly because that's what everyday lore says should happen.
  • When people reflect back on their own life, they feel like their early years went by very slowly and their later years go by more quickly. This could be the source of the belief that time goes more quickly as they age.
  •  "Most people feel that time is currently passing faster for them than it did in the past," Janssen writes me in an email. "They have forgotten how they experienced the passage of time when they were younger."
  • We use significant events as signposts to gauge the passage of time. The fewer events, the faster time seems to go by.
  • Childhood is full of big, memorable moments like learning to ride a bike or making first friends. By contrast, adult life becomes ordinary and mechanized, and ambles along by.
  • Each passing year converts some of this experience into automatic routine which we hardly notice at all, the days and weeks smooth themselves out in recollection, and the years grow hollow and collapse.
  • Each new minute represents a smaller fraction of our lives. One day as a 10 year old represents about .027 percent of the kid's life. A day for a 60 year old? .0045 percent. The kid's life is just... bigger.
  • Also, our ability to recall events declines with age. If we can't remember a time, it didn't happen.
  • "[F]inding that there is insufficient time to get things done may be reinterpreted as the feeling that time is passing quickly," they write. Deadlines always come sooner than we'd like.
  • Psychologists have long understood the phenomenon called "forward telescoping" — i.e., our tendency to underestimate how long ago very memorable events occurred. "Because we know that memories fade over time, we use the clarity of a memory as a guide to its recency," science writer Claudia Hammond writes in her book Time Warped. "So if a memory seems unclear we assumed it happened longer ago." But very clear memories are assumed to be more recent.
  • If our memories can trick us into thinking time is moving quickly, then maybe there are ways to trick our brains into thinking that time is slowing down — such as committing to breaking routines and learning new things. You're more likely to remember learning how to skydive than watching another hour of mindless television.

  • The White House told reporters on Thursday that, despite the imminent passage of NSA reform, they still believe Edward Snowden still belongs in prison (presumably for life, given his potential charges), while at the same time, brazenly taking credit for the USA Freedom Act passing, saying that “historians” would consider it part of Obama’s “legacy.”
  • even those in Congress who were campaigning for stronger NSA reform than the bill that passed the Senate are afraid to directly credit Snowden and, in many cases, still condemn him. Some cling to the erroneous belief that Snowden should come back to the US if he’s really a whistleblower because he could “tell his story to a jury.”
  • Without Edward Snowden, there would be no debate about the mass surveillance of Americans by the NSA. The Second Circuit Court of Appeals would not have ruled such surveillance illegal, tech companies would not encrypt our phone calls and text messages, and Congress certainly would not have passed the USA Freedom Act - no matter how meager its reforms actually are

To Justify Every 'A,' Some Professors Hand Over Grading Power to Outsiders - Technology... - 0 views

  • The best way to eliminate grade inflation is to take professors out of the grading process: Replace them with professional evaluators who never meet the students, and who don't worry that students will punish harsh grades with poor reviews. That's the argument made by leaders of Western Governors University, which has hired 300 adjunct professors who do nothing but grade student work.
  • These efforts raise the question: What if professors aren't that good at grading? What if the model of giving instructors full control over grades is fundamentally flawed? As more observers call for evidence of college value in an era of ever-rising tuition costs, game-changing models like these are getting serious consideration.
  • Professors do score poorly when it comes to fair grading, according to a study published in July in the journal Teachers College Record. After crunching the numbers on decades' worth of grade reports from about 135 colleges, the researchers found that average grades have risen for 30 years, and that A is now the most common grade given at most colleges. The authors, Stuart Rojstaczer and Christopher Healy, argue that a "consumer-based approach" to higher education has created subtle incentives for professors to give higher marks than deserved. "The standard practice of allowing professors free rein in grading has resulted in grades that bear little relation to actual performance," the two professors concluded.

  • Western Governors is entirely online, for one thing. Technically it doesn't offer courses; instead it provides mentors who help students prepare for a series of high-stakes homework assignments. Those assignments are designed by a team of professional test-makers to prove competence in various subject areas. The idea is that as long as students can leap all of those hurdles, they deserve degrees, whether or not they've ever entered a classroom, watched a lecture video, or participated in any other traditional teaching experience. The model is called "competency-based education."
  • Ms. Johnson explains that Western Governors essentially splits the role of the traditional professor into two jobs. Instructional duties fall to a group the university calls "course mentors," who help students master material. The graders, or evaluators, step in once the homework is filed, with the mind-set of, "OK, the teaching's done, now our job is to find out how much you know," says Ms. Johnson. They log on to a Web site called TaskStream and pluck the first assignment they see. The institution promises that every assignment will be graded within two days of submission.
  • Western Governors requires all evaluators to hold at least a master's degree in the subject they're grading.
  • Evaluators are required to write extensive comments on each task, explaining why the student passed or failed to prove competence in the requisite skill. No letter grades are given—students either pass or fail each task.
  • Another selling point is the software's fast response rate. It can grade a batch of 1,000 essay tests in minutes. Professors can set the software to return the grade immediately and can give students the option of making revisions and resubmitting their work on the spot.
  • All evaluators initially receive a month of training, conducted online, about how to follow each task's grading guidelines, which lay out characteristics of a passing score.
  • Other evaluators want to push talented students to do more than the university's requirements for a task, or to allow a struggling student to pass if he or she is just under the bar. "Some people just can't acclimate to a competency-based environment," says Ms. Johnson. "I tell them, If they don't buy this, they need to not be here.
  • She and some teaching assistants scored the tests by hand and compared their performance with the computer's.
  • The graduate students became fatigued and made mistakes after grading several tests in a row, she told me, "but the machine was right-on every time."
  • He argues that students like the idea that their tests are being evaluated in a consistent way.
  • The graders must regularly participate in "calibration exercises," in which they grade a simulated assignment to make sure they are all scoring consistently. As the phrase suggests, the process is designed to run like a well-oiled machine.
  • He said once students get essays back instantly, they start to view essay tests differently. "It's almost like a big math problem. You don't expect to get everything right the first time, but you work through it.
  • robot grading is the hottest trend in testing circles, says Jacqueline Leighton, a professor of educational psychology at the University of Alberta who edits the journal Educational Measurement: Issues and Practice. Companies building essay-grading robots include the Educational Testing Service, which sells e-rater, and Pearson Education, which makes Intelligent Essay Assessor. "The research is promising, but they're still very much in their infancy," Ms. Leighton says.

There's No Such Thing As 'Sound Science' | FiveThirtyEight - 1 views

  • cience is being turned against itself. For decades, its twin ideals of transparency and rigor have been weaponized by those who disagree with results produced by the scientific method. Under the Trump administration, that fight has ramped up again.
  • The same entreaties crop up again and again: We need to root out conflicts. We need more precise evidence. What makes these arguments so powerful is that they sound quite similar to the points raised by proponents of a very different call for change that’s coming from within science.
  • Despite having dissimilar goals, the two forces espouse principles that look surprisingly alike: Science needs to be transparent. Results and methods should be openly shared so that outside researchers can independently reproduce and validate them. The methods used to collect and analyze data should be rigorous and clear, and conclusions must be supported by evidence.

  • they’re also used as talking points by politicians who are working to make it more difficult for the EPA and other federal agencies to use science in their regulatory decision-making, under the guise of basing policy on “sound science.” Science’s virtues are being wielded against it.
  • What distinguishes the two calls for transparency is intent: Whereas the “open science” movement aims to make science more reliable, reproducible and robust, proponents of “sound science” have historically worked to amplify uncertainty, create doubt and undermine scientific discoveries that threaten their interests.
  • “Our criticisms are founded in a confidence in science,” said Steven Goodman, co-director of the Meta-Research Innovation Center at Stanford and a proponent of open science. “That’s a fundamental difference — we’re critiquing science to make it better. Others are critiquing it to devalue the approach itself.”
  • alls to base public policy on “sound science” seem unassailable if you don’t know the term’s history. The phrase was adopted by the tobacco industry in the 1990s to counteract mounting evidence linking secondhand smoke to cancer.
  • The sound science tactic exploits a fundamental feature of the scientific process: Science does not produce absolute certainty. Contrary to how it’s sometimes represented to the public, science is not a magic wand that turns everything it touches to truth. Instead, it’s a process of uncertainty reduction, much like a game of 20 Questions.
  • Any given study can rarely answer more than one question at a time, and each study usually raises a bunch of new questions in the process of answering old ones. “Science is a process rather than an answer,” said psychologist Alison Ledgerwood of the University of California, Davis. Every answer is provisional and subject to change in the face of new evidence. It’s not entirely correct to say that “this study proves this fact,” Ledgerwood said. “We should be talking instead about how science increases or decreases our confidence in something.”
  • While insisting that they merely wanted to ensure that public policy was based on sound science, tobacco companies defined the term in a way that ensured that no science could ever be sound enough. The only sound science was certain science, which is an impossible standard to achieve.
  • “Doubt is our product,” wrote one employee of the Brown & Williamson tobacco company in a 1969 internal memo. The note went on to say that doubt “is the best means of competing with the ‘body of fact’” and “establishing a controversy.” These strategies for undermining inconvenient science were so effective that they’ve served as a sort of playbook for industry interests ever since
  • Doubt merchants aren’t pushing for knowledge, they’re practicing what Proctor has dubbed “agnogenesis” — the intentional manufacture of ignorance. This ignorance isn’t simply the absence of knowing something; it’s a lack of comprehension deliberately created by agents who don’t want you to know,
  • In the hands of doubt-makers, transparency becomes a rhetorical move. “It’s really difficult as a scientist or policy maker to make a stand against transparency and openness, because well, who would be against it?
  • But at the same time, “you can couch everything in the language of transparency and it becomes a powerful weapon.” For instance, when the EPA was preparing to set new limits on particulate pollution in the 1990s, industry groups pushed back against the research and demanded access to primary data (including records that researchers had promised participants would remain confidential) and a reanalysis of the evidence. Their calls succeeded and a new analysis was performed. The reanalysis essentially confirmed the original conclusions, but the process of conducting it delayed the implementation of regulations and cost researchers time and money.
  • Delay is a time-tested strategy. “Gridlock is the greatest friend a global warming skeptic has,” said Marc Morano, a prominent critic of global warming research
  • which has received funding from the oil and gas industry. “We’re the negative force. We’re just trying to stop stuff.”
  • these ploys are getting a fresh boost from Congress. The Data Quality Act (also known as the Information Quality Act) was reportedly written by an industry lobbyist and quietly passed as part of an appropriations bill in 2000. The rule mandates that federal agencies ensure the “quality, objectivity, utility, and integrity of information” that they disseminate, though it does little to define what these terms mean. The law also provides a mechanism for citizens and groups to challenge information that they deem inaccurate, including science that they disagree with. “It was passed in this very quiet way with no explicit debate about it — that should tell you a lot about the real goals,” Levy said.
  • in the 20 months following its implementation, the act was repeatedly used by industry groups to push back against proposed regulations and bog down the decision-making process. Instead of deploying transparency as a fundamental principle that applies to all science, these interests have used transparency as a weapon to attack very particular findings that they would like to eradicate.
  • Now Congress is considering another way to legislate how science is used. The Honest Act, a bill sponsored by Rep. Lamar Smith of Texas,3The bill has been passed by the House but still awaits a vote in the Senate. is another example of what Levy calls a “Trojan horse” law that uses the language of transparency as a cover to achieve other political goals. Smith’s legislation would severely limit the kind of evidence the EPA could use for decision-making. Only studies whose raw data and computer codes were publicly available would be allowed for consideration.
  • It might seem like an easy task to sort good science from bad, but in reality it’s not so simple. “There’s a misplaced idea that we can definitively distinguish the good from the not-good science, but it’s all a matter of degree,” said Brian Nosek, executive director of the Center for Open Science. “There is no perfect study.” Requiring regulators to wait until they have (nonexistent) perfect evidence is essentially “a way of saying, ‘We don’t want to use evidence for our decision-making,’
  • ost scientific controversies aren’t about science at all, and once the sides are drawn, more data is unlikely to bring opponents into agreement.
  • objective knowledge is not enough to resolve environmental controversies. “While these controversies may appear on the surface to rest on disputed questions of fact, beneath often reside differing positions of value; values that can give shape to differing understandings of what ‘the facts’ are.” What’s needed in these cases isn’t more or better science, but mechanisms to bring those hidden values to the forefront of the discussion so that they can be debated transparently. “As long as we continue down this unabashedly naive road about what science is, and what it is capable of doing, we will continue to fail to reach any sort of meaningful consensus on these matters,”
  • The dispute over tobacco was never about the science of cigarettes’ link to cancer. It was about whether companies have the right to sell dangerous products and, if so, what obligations they have to the consumers who purchased them.
  • Similarly, the debate over climate change isn’t about whether our planet is heating, but about how much responsibility each country and person bears for stopping it
  • While researching her book “Merchants of Doubt,” science historian Naomi Oreskes found that some of the same people who were defending the tobacco industry as scientific experts were also receiving industry money to deny the role of human activity in global warming. What these issues had in common, she realized, was that they all involved the need for government action. “None of this is about the science. All of this is a political debate about the role of government,”
  • These controversies are really about values, not scientific facts, and acknowledging that would allow us to have more truthful and productive debates. What would that look like in practice? Instead of cherry-picking evidence to support a particular view (and insisting that the science points to a desired action), the various sides could lay out the values they are using to assess the evidence.
  • For instance, in Europe, many decisions are guided by the precautionary principle — a system that values caution in the face of uncertainty and says that when the risks are unclear, it should be up to industries to show that their products and processes are not harmful, rather than requiring the government to prove that they are harmful before they can be regulated. By contrast, U.S. agencies tend to wait for strong evidence of harm before issuing regulations
  • the difference between them comes down to priorities: Is it better to exercise caution at the risk of burdening companies and perhaps the economy, or is it more important to avoid potential economic downsides even if it means that sometimes a harmful product or industrial process goes unregulated?
  • But science can’t tell us how risky is too risky to allow products like cigarettes or potentially harmful pesticides to be sold — those are value judgements that only humans can make.

NCAA Looms Large In Debate Over Transgender Sports Restrictions : NPR - 0 views

  • When the South Dakota state legislature passed HB 1217 in early March, South Dakota Republican Gov. Kristi Noem tweeted that she was "excited" to sign it.That bill would have stopped transgender girls and women from playing on sports teams designated for girls and women.
  • These types of bills have been introduced in 25 states nationwide and have become a nationwide cause for social conservatives like Noem.
  • The ongoing fight in South Dakota is indicative not only of the way the issue of transgender girls in sports has become a nationwide phenomenon, but of the way that the NCAA looms over debates over transgender rights, and especially over the fight over transgender sports bans
  • ...7 more annotations...
  • In 2016, that state passed a bill restricting which bathrooms transgender people could use.
  • Because of that law, the NCAA and other sports organizations pulled events from the state. That included seven NCAA championship events, among them two rounds of men's March Madness basketball games.
  • Proponents believe the laws will keep girls and women's sports free of unfair competition.
  • In other words, it's a variety of NCAA events — well beyond March Madness — that can affect a city's economy, especially a small city like Sioux Falls. For now, people like Lee will be watching closely to see what the South Dakota legislature does next with the bill.
  • The NCAA is uniquely situated in this debate in that it is an economic force and a sporting organization - one that already has a policy on transgender athletes. That 2011 policy does allow transgender athletes to participate on their gender's teams.
  • Idaho passed the country's first transgender sports ban last year. The NCAA came out against that bill, calling it "harmful to transgender student athletes."
  • More than 500 student athletes have signed onto a letter asking the NCAA not to host events in states with these laws.

House Democrats look to pass gun control legislation by early June - 0 views

  • House Democrats will try to advance a raft of gun control bills on Thursday in the wake of two high-profile mass shootings that rocked the nation earlier this month.

  • Senate Republicans have for years blocked progress on any gun safety legislation. They opposed efforts to tighten gun regulations both when they held the majority, and even now when they can threaten an indefinite filibuster if Democrats can’t come up with the 60 votes required to circumvent the stalling tactic.
  • “It’s much easier to scream about guns than it is to demand answer about where our culture is failing,” Cruz added in a separate social media post on Saturday.
  • Disapproval from Cruz and other Senate Republicans will likely doom any legislation Nadler and other House Democrats manage to pass.
  • Democrats dispute the claim that lawmakers need to target mental illness more so than the availability of guns to reduce shooting violence in the U.S. They say that similar rates of mental illness in other developed nations across the globe prove that mental illness alone cannot fully explain the prevalence of mass shootings in the U.S.

  • North Carolina has banned using recent science to guide policy making. House Bill 819, which passed today after the governor let the deadline to stop it slip, restricts all sea-level predictions used for policy-making to be based on "historical data," effectively sending science back to 1900. The law will prevent policy-makers from using a recent study by the state's Coastal Resources Commission (CRC) which predicted the sea level will rise by 39 inches in the next century.

The Ethical Will, an Ancient Concept, Is Revamped for the Tech Age - NYTimes.com - 2 views

  • These days, ethical wills are nonbinding documents that are increasingly seen as important legacy-building ingredients, say experts, because they can convey a person’s deep inner values and beliefs, even helping soothe ruffled feathers when dispensing family assets.

At the Existentialist Café: Freedom, Being, and Apricot Cocktails with Jean-P... - 0 views

  • The phenomenologists’ leading thinker, Edmund Husserl, provided a rallying cry, ‘To the things themselves!’ It meant: don’t waste time on the interpretations that accrue upon things, and especially don’t waste time wondering whether the things are real. Just look at this that’s presenting itself to you, whatever this may be, and describe it as precisely as possible.
  • You might think you have defined me by some label, but you are wrong, for I am always a work in progress. I create myself constantly through action, and this is so fundamental to my human condition that, for Sartre, it is the human condition, from the moment of first consciousness to the moment when death wipes it out. I am my own freedom: no more, no less.
  • Sartre wrote like a novelist — not surprisingly, since he was one. In his novels, short stories and plays as well as in his philosophical treatises, he wrote about the physical sensations of the world and the structures and moods of human life. Above all, he wrote about one big subject: what it meant to be free. Freedom, for him, lay at the heart of all human experience, and this set humans apart from all other kinds of object.
  • ...97 more annotations...
  • Sartre listened to his problem and said simply, ‘You are free, therefore choose — that is to say, invent.’ No signs are vouchsafed in this world, he said. None of the old authorities can relieve you of the burden of freedom. You can weigh up moral or practical considerations as carefully as you like, but ultimately you must take the plunge and do something, and it’s up to you what that something is.
  • Even if the situation is unbearable — perhaps you are facing execution, or sitting in a Gestapo prison, or about to fall off a cliff — you are still free to decide what to make of it in mind and deed. Starting from where you are now, you choose. And in choosing, you also choose who you will be.
  • The war had made people realise that they and their fellow humans were capable of departing entirely from civilised norms; no wonder the idea of a fixed human nature seemed questionable.
  • If this sounds difficult and unnerving, it’s because it is. Sartre does not deny that the need to keep making decisions brings constant anxiety. He heightens this anxiety by pointing out that what you do really matters. You should make your choices as though you were choosing on behalf of the whole of humanity, taking the entire burden of responsibility for how the human race behaves. If you avoid this responsibility by fooling yourself that you are the victim of circumstance or of someone else’s bad advice, you are failing to meet the demands of human life and choosing a fake existence, cut off from your own ‘authenticity’.
  • Along with the terrifying side of this comes a great promise: Sartre’s existentialism implies that it is possible to be authentic and free, as long as you keep up the effort.
  • almost all agreed that it was, as an article in Les nouvelles littéraires phrased it, a ‘sickening mixture of philosophic pretentiousness, equivocal dreams, physiological technicalities, morbid tastes and hesitant eroticism … an introspective embryo that one would take distinct pleasure in crushing’.
  • he offered a philosophy designed for a species that had just scared the hell out of itself, but that finally felt ready to grow up and take responsibility.
  • In this rebellious world, just as with the Parisian bohemians and Dadaists in earlier generations, everything that was dangerous and provocative was good, and everything that was nice or bourgeois was bad.
  • Such interweaving of ideas and life had a long pedigree, although the existentialists gave it a new twist. Stoic and Epicurean thinkers in the classical world had practised philosophy as a means of living well, rather than of seeking knowledge or wisdom for their own sake. By reflecting on life’s vagaries in philosophical ways, they believed they could become more resilient, more able to rise above circumstances, and better equipped to manage grief, fear, anger, disappointment or anxiety.
  • In the tradition they passed on, philosophy is neither a pure intellectual pursuit nor a collection of cheap self-help tricks, but a discipline for flourishing and living a fully human, responsible life.
  • For Kierkegaard, Descartes had things back to front. In his own view, human existence comes first: it is the starting point for everything we do, not the result of a logical deduction. My existence is active: I live it and choose it, and this precedes any statement I can make about myself.
  • Studying our own moral genealogy cannot help us to escape or transcend ourselves. But it can enable us to see our illusions more clearly and lead a more vital, assertive existence.
  • What was needed, he felt, was not high moral or theological ideals, but a deeply critical form of cultural history or ‘genealogy’ that would uncover the reasons why we humans are as we are, and how we came to be that way. For him, all philosophy could even be redefined as a form of psychology, or history.
  • For those oppressed on grounds of race or class, or for those fighting against colonialism, existentialism offered a change of perspective — literally, as Sartre proposed that all situations be judged according to how they appeared in the eyes of those most oppressed, or those whose suffering was greatest.
  • She observed that we need not expect moral philosophers to ‘live by’ their ideas in a simplistic way, as if they were following a set of rules. But we can expect them to show how their ideas are lived in. We should be able to look in through the windows of a philosophy, as it were, and see how people occupy it, how they move about and how they conduct themselves.
  • the existentialists inhabited their historical and personal world, as they inhabited their ideas. This notion of ‘inhabited philosophy’ is one I’ve borrowed from the English philosopher and novelist Iris Murdoch, who wrote the first full-length book on Sartre and was an early adopter of existentialism
  • What is existentialism anyway?
  • An existentialist who is also phenomenological provides no easy rules for dealing with this condition, but instead concentrates on describing lived experience as it presents itself. — By describing experience well, he or she hopes to understand this existence and awaken us to ways of living more authentic lives.
  • Existentialists concern themselves with individual, concrete human existence. — They consider human existence different from the kind of being other things have. Other entities are what they are, but as a human I am whatever I choose to make of myself at every moment. I am free — — and therefore I’m responsible for everything I do, a dizzying fact which causes — an anxiety inseparable from human existence itself.
  • On the other hand, I am only free within situations, which can include factors in my own biology and psychology as well as physical, historical and social variables of the world into which I have been thrown. — Despite the limitations, I always want more: I am passionately involved in personal projects of all kinds. — Human existence is thus ambiguous: at once boxed in by borders and yet transcendent and exhilarating. —
  • The first part of this is straightforward: a phenomenologist’s job is to describe. This is the activity that Husserl kept reminding his students to do. It meant stripping away distractions, habits, clichés of thought, presumptions and received ideas, in order to return our attention to what he called the ‘things themselves’. We must fix our beady gaze on them and capture them exactly as they appear, rather than as we think they are supposed to be.
  • Husserl therefore says that, to phenomenologically describe a cup of coffee, I should set aside both the abstract suppositions and any intrusive emotional associations. Then I can concentrate on the dark, fragrant, rich phenomenon in front of me now. This ‘setting aside’ or ‘bracketing out’ of speculative add-ons Husserl called epoché — a term borrowed from the ancient Sceptics,
  • The point about rigour is crucial; it brings us back to the first half of the command to describe phenomena. A phenomenologist cannot get away with listening to a piece of music and saying, ‘How lovely!’ He or she must ask: is it plaintive? is it dignified? is it colossal and sublime? The point is to keep coming back to the ‘things themselves’ — phenomena stripped of their conceptual baggage — so as to bail out weak or extraneous material and get to the heart of the experience.
  • Husserlian ‘bracketing out’ or epoché allows the phenomenologist to temporarily ignore the question ‘But is it real?’, in order to ask how a person experiences his or her world. Phenomenology gives a formal mode of access to human experience. It lets philosophers talk about life more or less as non-philosophers do, while still being able to tell themselves they are being methodical and rigorous.
  • Besides claiming to transform the way we think about reality, phenomenologists promised to change how we think about ourselves. They believed that we should not try to find out what the human mind is, as if it were some kind of substance. Instead, we should consider what it does, and how it grasps its experiences.
  • For Brentano, this reaching towards objects is what our minds do all the time. Our thoughts are invariably of or about something, he wrote: in love, something is loved, in hatred, something is hated, in judgement, something is affirmed or denied. Even when I imagine an object that isn’t there, my mental structure is still one of ‘about-ness’ or ‘of-ness’.
  • Except in deepest sleep, my mind is always engaged in this aboutness: it has ‘intentionality’. Having taken the germ of this from Brentano, Husserl made it central to his whole philosophy.
  • Husserl saw in the idea of intentionality a way to sidestep two great unsolved puzzles of philosophical history: the question of what objects ‘really’ are, and the question of what the mind ‘really’ is. By doing the epoché and bracketing out all consideration of reality from both topics, one is freed to concentrate on the relationship in the middle. One can apply one’s descriptive energies to the endless dance of intentionality that takes place in our lives: the whirl of our minds as they seize their intended phenomena one after the other and whisk them around the floor,
  • Understood in this way, the mind hardly is anything at all: it is its aboutness. This makes the human mind (and possibly some animal minds) different from any other naturally occurring entity. Nothing else can be as thoroughly about or of things as the mind is:
  • Some Eastern meditation techniques aim to still this scurrying creature, but the extreme difficulty of this shows how unnatural it is to be mentally inert. Left to itself, the mind reaches out in all directions as long as it is awake — and even carries on doing it in the dreaming phase of its sleep.
  • a mind that is experiencing nothing, imagining nothing, or speculating about nothing can hardly be said to be a mind at all.
  • Three simple ideas — description, phenomenon, intentionality — provided enough inspiration to keep roomfuls of Husserlian assistants busy in Freiburg for decades. With all of human existence awaiting their attention, how could they ever run out of things to do?
  • For Sartre, this gives the mind an immense freedom. If we are nothing but what we think about, then no predefined ‘inner nature’ can hold us back. We are protean.
  • way of this interpretation. Real, not real; inside, outside; what difference did it make? Reflecting on this, Husserl began turning his phenomenology into a branch of ‘idealism’ — the philosophical tradition which denied external reality and defined everything as a kind of private hallucination.
  • For Sartre, if we try to shut ourselves up inside our own minds, ‘in a nice warm room with the shutters closed’, we cease to exist. We have no cosy home: being out on the dusty road is the very definition of what we are.
  • One might think that, if Heidegger had anything worth saying, he could have communicated it in ordinary language. The fact is that he does not want to be ordinary, and he may not even want to communicate in the usual sense. He wants to make the familiar obscure, and to vex us. George Steiner thought that Heidegger’s purpose was less to be understood than to be experienced through a ‘felt strangeness’.
  • He takes Dasein in its most ordinary moments, then talks about it in the most innovative way he can. For Heidegger, Dasein’s everyday Being is right here: it is Being-in-the-world, or In-der-Welt-sein. The main feature of Dasein’s everyday Being-in-the-world right here is that it is usually busy doing something.
  • Thus, for Heidegger, all Being-in-the-world is also a ‘Being-with’ or Mitsein. We cohabit with others in a ‘with-world’, or Mitwelt. The old philosophical problem of how we prove the existence of other minds has now vanished. Dasein swims in the with-world long before it wonders about other minds.
  • Sometimes the best-educated people were those least inclined to take the Nazis seriously, dismissing them as too absurd to last. Karl Jaspers was one of those who made this mistake, as he later recalled, and Beauvoir observed similar dismissive attitudes among the French students in Berlin.
  • In any case, most of those who disagreed with Hitler’s ideology soon learned to keep their view to themselves. If a Nazi parade passed on the street, they would either slip out of view or give the obligatory salute like everyone else, telling themselves that the gesture meant nothing if they did not believe in it. As the psychologist Bruno Bettelheim later wrote of this period, few people will risk their life for such a small thing as raising an arm — yet that is how one’s powers of resistance are eroded away, and eventually one’s responsibility and integrity go with them.
  • for Arendt, if you do not respond adequately when the times demand it, you show a lack of imagination and attention that is as dangerous as deliberately committing an abuse. It amounts to disobeying the one command she had absorbed from Heidegger in those Marburg days: Think!
  • ‘Everything takes place under a kind of anaesthesia. Objectively dreadful events produce a thin, puny emotional response. Murders are committed like schoolboy pranks. Humiliation and moral decay are accepted like minor incidents.’ Haffner thought modernity itself was partly to blame: people had become yoked to their habits and to mass media, forgetting to stop and think, or to disrupt their routines long enough to question what was going on.
  • Heidegger’s former lover and student Hannah Arendt would argue, in her 1951 study The Origins of Totalitarianism, that totalitarian movements thrived at least partly because of this fragmentation in modern lives, which made people more vulnerable to being swept away by demagogues. Elsewhere, she coined the phrase ‘the banality of evil’ to describe the most extreme failures of personal moral awareness.
  • His communicative ideal fed into a whole theory of history: he traced all civilisation to an ‘Axial Period’ in the fifth century BC, during which philosophy and culture exploded simultaneously in Europe, the Middle East and Asia, as though a great bubble of minds had erupted from the earth’s surface. ‘True philosophy needs communion to come into existence,’ he wrote, and added, ‘Uncommunicativeness in a philosopher is virtually a criterion of the untruth of his thinking.’
  • The idea of being called to authenticity became a major theme in later existentialism, the call being interpreted as saying something like ‘Be yourself!’, as opposed to being phony. For Heidegger, the call is more fundamental than that. It is a call to take up a self that you didn’t know you had: to wake up to your Being. Moreover, it is a call to action. It requires you to do something: to take a decision of some sort.
  • Being and Time contained at least one big idea that should have been of use in resisting totalitarianism. Dasein, Heidegger wrote there, tends to fall under the sway of something called das Man or ‘the they’ — an impersonal entity that robs us of the freedom to think for ourselves. To live authentically requires resisting or outwitting this influence, but this is not easy because das Man is so nebulous. Man in German does not mean ‘man’ as in English (that’s der Mann), but a neutral abstraction, something like ‘one’ in the English phrase ‘one doesn’t do that’,
  • for Heidegger, das Man is me. It is everywhere and nowhere; it is nothing definite, but each of us is it. As with Being, it is so ubiquitous that it is difficult to see. If I am not careful, however, das Man takes over the important decisions that should be my own. It drains away my responsibility or ‘answerability’. As Arendt might put it, we slip into banality, failing to think.
  • Jaspers focused on what he called Grenzsituationen — border situations, or limit situations. These are the moments when one finds oneself constrained or boxed in by what is happening, but at the same time pushed by these events towards the limits or outer edge of normal experience. For example, you might have to make a life-or-death choice, or something might remind you suddenly of your mortality,
  • Jaspers’ interest in border situations probably had much to do with his own early confrontation with mortality. From childhood, he had suffered from a heart condition so severe that he always expected to die at any moment. He also had emphysema, which forced him to speak slowly, taking long pauses to catch his breath. Both illnesses meant that he had to budget his energies with care in order to get his work done without endangering his life.
  • If I am to resist das Man, I must become answerable to the call of my ‘voice of conscience’. This call does not come from God, as a traditional Christian definition of the voice of conscience might suppose. It comes from a truly existentialist source: my own authentic self. Alas, this voice is one I do not recognise and may not hear, because it is not the voice of my habitual ‘they-self’. It is an alien or uncanny version of my usual voice. I am familiar with my they-self, but not with my unalienated voice — so, in a weird twist, my real voice is the one that sounds strangest to me.
  • Marcel developed a strongly theological branch of existentialism. His faith distanced him from both Sartre and Heidegger, but he shared a sense of how history makes demands on individuals. In his essay ‘On the Ontological Mystery’, written in 1932 and published in the fateful year of 1933, Marcel wrote of the human tendency to become stuck in habits, received ideas, and a narrow-minded attachment to possessions and familiar scenes. Instead, he urged his readers to develop a capacity for remaining ‘available’ to situations as they arise. Similar ideas of disponibilité or availability had been explored by other writers,
  • Marcel made it his central existential imperative. He was aware of how rare and difficult it was. Most people fall into what he calls ‘crispation’: a tensed, encrusted shape in life — ‘as though each one of us secreted a kind of shell which gradually hardened and imprisoned him’.
  • Bettelheim later observed that, under Nazism, only a few people realised at once that life could not continue unaltered: these were the ones who got away quickly. Bettelheim himself was not among them. Caught in Austria when Hitler annexed it, he was sent first to Dachau and then to Buchenwald, but was then released in a mass amnesty to celebrate Hitler’s birthday in 1939 — an extraordinary reprieve, after which he left at once for America.
  • we are used to reading philosophy as offering a universal message for all times and places — or at least as aiming to do so. But Heidegger disliked the notion of universal truths or universal humanity, which he considered a fantasy. For him, Dasein is not defined by shared faculties of reason and understanding, as the Enlightenment philosophers thought. Still less is it defined by any kind of transcendent eternal soul, as in religious tradition. We do not exist on a higher, eternal plane at all. Dasein’s Being is local: it has a historical situation, and is constituted in time and place.
  • For Marcel, learning to stay open to reality in this way is the philosopher’s prime job. Everyone can do it, but the philosopher is the one who is called on above all to stay awake, so as to be the first to sound the alarm if something seems wrong.
  • Second, it also means understanding that we are historical beings, and grasping the demands our particular historical situation is making on us. In what Heidegger calls ‘anticipatory resoluteness’, Dasein discovers ‘that its uttermost possibility lies in giving itself up’. At that moment, through Being-towards-death and resoluteness in facing up to one’s time, one is freed from the they-self and attains one’s true, authentic self.
  • If we are temporal beings by our very nature, then authentic existence means accepting, first, that we are finite and mortal. We will die: this all-important realisation is what Heidegger calls authentic ‘Being-towards-Death’, and it is fundamental to his philosophy.
  • Hannah Arendt, instead, left early on: she had the benefit of a powerful warning. Just after the Nazi takeover, in spring 1933, she had been arrested while researching materials on anti-Semitism for the German Zionist Organisation at Berlin’s Prussian State Library. Her apartment was searched; both she and her mother were locked up briefly, then released. They fled, without stopping to arrange travel documents. They crossed to Czechoslovakia (then still safe) by a method that sounds almost too fabulous to be true: a sympathetic German family on the border had a house with its front door in Germany and its back door in Czechoslovakia. The family would invite people for dinner, then let them leave through the back door at night.
  • As Sartre argued in his 1943 review of The Stranger, basic phenomenological principles show that experience comes to us already charged with significance. A piano sonata is a melancholy evocation of longing. If I watch a soccer match, I see it as a soccer match, not as a meaningless scene in which a number of people run around taking turns to apply their lower limbs to a spherical object. If the latter is what I’m seeing, then I am not watching some more essential, truer version of soccer; I am failing to watch it properly as soccer at all.
  • Much as they liked Camus personally, neither Sartre nor Beauvoir accepted his vision of absurdity. For them, life is not absurd, even when viewed on a cosmic scale, and nothing can be gained by saying it is. Life for them is full of real meaning, although that meaning emerges differently for each of us.
  • For Sartre, we show bad faith whenever we portray ourselves as passive creations of our race, class, job, history, nation, family, heredity, childhood influences, events, or even hidden drives in our subconscious which we claim are out of our control. It is not that such factors are unimportant: class and race, in particular, he acknowledged as powerful forces in people’s lives, and Simone de Beauvoir would soon add gender to that list.
  • Sartre takes his argument to an extreme point by asserting that even war, imprisonment or the prospect of imminent death cannot take away my existential freedom. They form part of my ‘situation’, and this may be an extreme and intolerable situation, but it still provides only a context for whatever I choose to do next. If I am about to die, I can decide how to face that death. Sartre here resurrects the ancient Stoic idea that I may not choose what happens to me, but I can choose what to make of it, spiritually speaking.
  • But the Stoics cultivated indifference in the face of terrible events, whereas Sartre thought we should remain passionately, even furiously engaged with what happens to us and with what we can achieve. We should not expect freedom to be anything less than fiendishly difficult.
  • Freedom does not mean entirely unconstrained movement, and it certainly does not mean acting randomly. We often mistake the very things that enable us to be free — context, meaning, facticity, situation, a general direction in our lives — for things that define us and take away our freedom. It is only with all of these that we can be free in a real sense.
  • Nor did he mean that privileged groups have the right to pontificate to the poor and downtrodden about the need to ‘take responsibility’ for themselves. That would be a grotesque misreading of Sartre’s point, since his sympathy in any encounter always lay with the more oppressed side. But for each of us — for me — to be in good faith means not making excuses for myself.
  • Camus’ novel gives us a deliberately understated vision of heroism and decisive action compared to those of Sartre and Beauvoir. One can only do so much. It can look like defeatism, but it shows a more realistic perception of what it takes to actually accomplish difficult tasks like liberating one’s country.
  • Camus just kept returning to his core principle: no torture, no killing — at least not with state approval. Beauvoir and Sartre believed they were taking a more subtle and more realistic view. If asked why a couple of innocuous philosophers had suddenly become so harsh, they would have said it was because the war had changed them in profound ways. It had shown them that one’s duties to humanity could be more complicated than they seemed. ‘The war really divided my life in two,’ Sartre said later.
  • Poets and artists ‘let things be’, but they also let things come out and show themselves. They help to ease things into ‘unconcealment’ (Unverborgenheit), which is Heidegger’s rendition of the Greek term alētheia, usually translated as ‘truth’. This is a deeper kind of truth than the mere correspondence of a statement to reality, as when we say ‘The cat is on the mat’ and point to a mat with a cat on it. Long before we can do this, both cat and mat must ‘stand forth out of concealedness’. They must un-hide themselves.
  • Heidegger does not use the word ‘consciousness’ here because — as with his earlier work — he is trying to make us think in a radically different way about ourselves. We are not to think of the mind as an empty cavern, or as a container filled with representations of things. We are not even supposed to think of it as firing off arrows of intentional ‘aboutness’, as in the earlier phenomenology of Brentano. Instead, Heidegger draws us into the depths of his Schwarzwald, and asks us to imagine a gap with sunlight filtering in. We remain in the forest, but we provide a relatively open spot where other beings can bask for a moment. If we did not do this, everything would remain in the thickets, hidden even to itself.
  • The astronomer Carl Sagan began his 1980 television series Cosmos by saying that human beings, though made of the same stuff as the stars, are conscious and are therefore ‘a way for the cosmos to know itself’. Merleau-Ponty similarly quoted his favourite painter Cézanne as saying, ‘The landscape thinks itself in me, and I am its consciousness.’ This is something like what Heidegger thinks humanity contributes to the earth. We are not made of spiritual nothingness; we are part of Being, but we also bring something unique with us. It is not much: a little open space, perhaps with a path and a bench like the one the young Heidegger used to sit on to do his homework. But through us, the miracle occurs.
  • Beauty aside, Heidegger’s late writing can also be troubling, with its increasingly mystical notion of what it is to be human. If one speaks of a human being mainly as an open space or a clearing, or a means of ‘letting beings be’ and dwelling poetically on the earth, then one doesn’t seem to be talking about any recognisable person. The old Dasein has become less human than ever. It is now a forestry feature.
  • Even today, Jaspers, the dedicated communicator, is far less widely read than Heidegger, who has influenced architects, social theorists, critics, psychologists, artists, film-makers, environmental activists, and innumerable students and enthusiasts — including the later deconstructionist and post-structuralist schools, which took their starting point from his late thinking. Having spent the late 1940s as an outsider and then been rehabilitated, Heidegger became the overwhelming presence in university philosophy all over the European continent from then on.
  • As Levinas reflected on this experience, it helped to lead him to a philosophy that was essentially ethical, rather than ontological like Heidegger’s. He developed his ideas from the work of Jewish theologian Martin Buber, whose I and Thou in 1923 had distinguished between my relationship with an impersonal ‘it’ or ‘them’, and the direct personal encounter I have with a ‘you’. Levinas took it further: when I encounter you, we normally meet face-to-face, and it is through your face that you, as another person, can make ethical demands on me. This is very different from Heidegger’s Mitsein or Being-with, which suggests a group of people standing alongside one another, shoulder to shoulder as if in solidarity — perhaps as a unified nation or Volk.
  • For Levinas, we literally face each other, one individual at a time, and that relationship becomes one of communication and moral expectation. We do not merge; we respond to one another. Instead of being co-opted into playing some role in my personal drama of authenticity, you look me in the eyes — and you remain Other. You remain you.
  • This relationship is more fundamental than the self, more fundamental than consciousness, more fundamental even than Being — and it brings an unavoidable ethical obligation. Ever since Husserl, phenomenologists and existentialists had being trying to stretch the definition of existence to incorporate our social lives and relationships. Levinas did more: he turned philosophy around entirely so that these relationships were the foundation of our existence, not an extension of it.
  • Her last work, The Need for Roots, argues, among other things, that none of us has rights, but each one of us has a near-infinite degree of duty and obligation to the other. Whatever the underlying cause of her death — and anorexia nervosa seems to have been involved — no one could deny that she lived out her philosophy with total commitment. Of all the lives touched on in this book, hers is surely the most profound and challenging application of Iris Murdoch’s notion that a philosophy can be ‘inhabited’.
  • Other thinkers took radical ethical turns during the war years. The most extreme was Simone Weil, who actually tried to live by the principle of putting other people’s ethical demands first. Having returned to France after her travels through Germany in 1932, she had worked in a factory so as to experience the degrading nature of such work for herself. When France fell in 1940, her family fled to Marseilles (against her protests), and later to the US and to Britain. Even in exile, Weil made extraordinary sacrifices. If there were people in the world who could not sleep in a bed, she would not do so either, so she slept on the floor.
  • The mystery tradition had roots in Kierkegaard’s ‘leap of faith’. It owed much to the other great nineteenth-century mystic of the impossible, Dostoevsky, and to older theological notions. But it also grew from the protracted trauma that was the first half of the twentieth century. Since 1914, and especially since 1939, people in Europe and elsewhere had come to the realisation that we cannot fully know or trust ourselves; that we have no excuses or explanations for what we do — and yet that we must ground our existence and relationships on something firm, because otherwise we cannot survive.
  • One striking link between these radical ethical thinkers, all on the fringes of our main story, is that they had religious faith. They also granted a special role to the notion of ‘mystery’ — that which cannot be known, calculated or understood, especially when it concerns our relationships with each other. Heidegger was different from them, since he rejected the religion he grew up with and had no real interest in ethics — probably as a consequence of his having no real interest in the human.
  • Meanwhile, the Christian existentialist Gabriel Marcel was also still arguing, as he had since the 1930s, that ethics trumps everything else in philosophy and that our duty to each other is so great as to play the role of a transcendent ‘mystery’. He too had been led to this position partly by a wartime experience: during the First World War he had worked for the Red Cross’ Information Service, with the unenviable job of answering relatives’ inquiries about missing soldiers. Whenever news came, he passed it on, and usually it was not good. As Marcel later said, this task permanently inoculated him against warmongering rhetoric of any kind, and it made him aware of the power of what is unknown in our lives.
  • As the play’s much-quoted and frequently misunderstood final line has it: ‘Hell is other people.’ Sartre later explained that he did not mean to say that other people were hellish in general. He meant that after death we become frozen in their view, unable any longer to fend off their interpretation. In life, we can still do something to manage the impression we make; in death, this freedom goes and we are left entombed in other’s people’s memories and perceptions.
  • We have to do two near-impossible things at once: understand ourselves as limited by circumstances, and yet continue to pursue our projects as though we are truly in control. In Beauvoir’s view, existentialism is the philosophy that best enables us to do this, because it concerns itself so deeply with both freedom and contingency. It acknowledges the radical and terrifying scope of our freedom in life, but also the concrete influences that other philosophies tend to ignore: history, the body, social relationships and the environment.
  • The aspects of our existence that limit us, Merleau-Ponty says, are the very same ones that bind us to the world and give us scope for action and perception. They make us what we are. Sartre acknowledged the need for this trade-off, but he found it more painful to accept. Everything in him longed to be free of bonds, of impediments and limitations
  • Of course we have to learn this skill of interpreting and anticipating the world, and this happens in early childhood, which is why Merleau-Ponty thought child psychology was essential to philosophy. This is an extraordinary insight. Apart from Rousseau, very few philosophers before him had taken childhood seriously; most wrote as though all human experience were that of a fully conscious, rational, verbal adult who has been dropped into this world from the sky — perhaps by a stork.
  • For Merleau-Ponty, we cannot understand our experience if we don’t think of ourselves in part as overgrown babies. We fall for optical illusions because we once learned to see the world in terms of shapes, objects and things relevant to our own interests. Our first perceptions came to us in tandem with our first active experiments in observing the world and reaching out to explore it, and are still linked with those experiences.
  • Another factor in all of this, for Merleau-Ponty, is our social existence: we cannot thrive without others, or not for long, and we need this especially in early life. This makes solipsistic speculation about the reality of others ridiculous; we could never engage in such speculation if we hadn’t already been formed by them.
  • As Descartes could have said (but didn’t), ‘I think, therefore other people exist.’ We grow up with people playing with us, pointing things out, talking, listening, and getting us used to reading emotions and movements; this is how we become capable, reflective, smoothly integrated beings.
  • In general, Merleau-Ponty thinks human experience only makes sense if we abandon philosophy’s time-honoured habit of starting with a solitary, capsule-like, immobile adult self, isolated from its body and world, which must then be connected up again — adding each element around it as though adding clothing to a doll. Instead, for him, we slide from the womb to the birth canal to an equally close and total immersion in the world. That immersion continues as long as we live, although we may also cultivate the art of partially withdrawing from time to time when we want to think or daydream.
  • When he looks for his own metaphor to describe how he sees consciousness, he comes up with a beautiful one: consciousness, he suggests, is like a ‘fold’ in the world, as though someone had crumpled a piece of cloth to make a little nest or hollow. It stays for a while, before eventually being unfolded and smoothed away. There is something seductive, even erotic, in this idea of my conscious self as an improvised pouch in the cloth of the world. I still have my privacy — my withdrawing room. But I am part of the world’s fabric, and I remain formed out of it for as long as I am here.
  • By the time of these works, Merleau-Ponty is taking his desire to describe experience to the outer limits of what language can convey. Just as with the late Husserl or Heidegger, or Sartre in his Flaubert book, we see a philosopher venturing so far from shore that we can barely follow. Emmanuel Levinas would head out to the fringes too, eventually becoming incomprehensible to all but his most patient initiates.
  • Sartre once remarked — speaking of a disagreement they had about Husserl in 1941 — that ‘we discovered, astounded, that our conflicts had, at times, stemmed from our childhood, or went back to the elementary differences of our two organisms’. Merleau-Ponty also said in an interview that Sartre’s work seemed strange to him, not because of philosophical differences, but because of a certain ‘register of feeling’, especially in Nausea, that he could not share. Their difference was one of temperament and of the whole way the world presented itself to them.
  • The two also differed in their purpose. When Sartre writes about the body or other aspects of experience, he generally does it in order to make a different point. He expertly evokes the grace of his café waiter, gliding between the tables, bending at an angle just so, steering the drink-laden tray through the air on the tips of his fingers — but he does it all in order to illustrate his ideas about bad faith. When Merleau-Ponty writes about skilled and graceful movement, the movement itself is his point. This is the thing he wants to understand.
  • We can never move definitively from ignorance to certainty, for the thread of the inquiry will constantly lead us back to ignorance again. This is the most attractive description of philosophy I’ve ever read, and the best argument for why it is worth doing, even (or especially) when it takes us no distance at all from our starting point.
  • By prioritising perception, the body, social life and childhood development, Merleau-Ponty gathered up philosophy’s far-flung outsider subjects and brought them in to occupy the centre of his thought.
  • In his inaugural lecture at the Collège de France on 15 January 1953, published as In Praise of Philosophy, he said that philosophers should concern themselves above all with whatever is ambiguous in our experience. At the same time, they should think clearly about these ambiguities, using reason and science. Thus, he said, ‘The philosopher is marked by the distinguishing trait that he possesses inseparably the taste for evidence and the feeling for ambiguity.’ A constant movement is required between these two
  • As Sartre wrote in response to Hiroshima, humanity had now gained the power to wipe itself out, and must decide every single day that it wanted to live. Camus also wrote that humanity faced the task of choosing between collective suicide and a more intelligent use of its technology — ‘between hell and reason’. After 1945, there seemed little reason to trust in humanity’s ability to choose well.
  • Merleau-Ponty observed in a lecture of 1951 that, more than any previous century, the twentieth century had reminded people how ‘contingent’ their lives were — how at the mercy of historical events and other changes that they could not control. This feeling went on long after the war ended. After the A-bombs were dropped on Hiroshima and Nagasaki, many feared that a Third World War would not be long in coming, this time between the Soviet Union and the United States.

Does Your Language Shape How You Think? - NYTimes.com - 1 views

  • it turns out that the colors that our language routinely obliges us to treat as distinct can refine our purely visual sensitivity to certain color differences in reality, so that our brains are trained to exaggerate the distance between shades of color if these have different names in our language.
  • some languages, like Matses in Peru, oblige their speakers, like the finickiest of lawyers, to specify exactly how they came to know about the facts they are reporting. You cannot simply say, as in English, “An animal passed here.” You have to specify, using a different verbal form, whether this was directly experienced (you saw the animal passing), inferred (you saw footprints), conjectured (animals generally pass there that time of day), hearsay or such. If a statement is reported with the incorrect “evidentiality,” it is considered a lie.
  • For many years, our mother tongue was claimed to be a “prison house” that constrained our capacity to reason. Once it turned out that there was no evidence for such claims, this was taken as proof that people of all cultures think in fundamentally the same way. But surely it is a mistake to overestimate the importance of abstract reasoning in our lives. After all, how many daily decisions do we make on the basis of deductive logic compared with those guided by gut feeling, intuition, emotions, impulse or practical skills? The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies.

How Does Light Travel? - Universe Today - 0 views

  • However, there remains many fascinating and unanswered questions when it comes to light, many of which arise from its dual nature. For instance, how is it that light can be apparently without mass, but still behave as a particle? And how can it behave like a wave and pass through a vacuum, when all other waves require a medium to propagate?
  • This included rejecting Aristotle’s theory of light, which viewed it as being a disturbance in the air (one of his four “elements” that composed matter), and embracing the more mechanistic view that light was composed of indivisible atoms
  • In Young’s version of the experiment, he used a slip of paper with slits cut into it, and then pointed a light source at them to measure how light passed through it
  • ...6 more annotations...
  • According to classical (i.e. Newtonian) particle theory, the results of the experiment should have corresponded to the slits, the impacts on the screen appearing in two vertical lines. Instead, the results showed that the coherent beams of light were interfering, creating a pattern of bright and dark bands on the screen. This contradicted classical particle theory, in which particles do not interfere with each other, but merely collide.
  • The only possible explanation for this pattern of interference was that the light beams were in fact behaving as waves
  • By the late 19th century, James Clerk Maxwell proposed that light was an electromagnetic wave, and devised several equations (known as Maxwell’s equations) to describe how electric and magnetic fields are generated and altered by each other and by charges and currents. By conducting measurements of different types of radiation (magnetic fields, ultraviolet and infrared radiation), he was able to calculate the speed of light in a vacuum (represented as c).
  • For one, it introduced the idea that major changes occur when things move close the speed of light, including the time-space frame of a moving body appearing to slow down and contract in the direction of motion when measured in the frame of the observer. After centuries of increasingly precise measurements, the speed of light was determined to be 299,792,458 m/s in 1975
  • According to his theory, wave function also evolves according to a differential equation (aka. the Schrödinger equation). For particles with mass, this equation has solutions; but for particles with no mass, no solution existed. Further experiments involving the Double-Slit Experiment confirmed the dual nature of photons. where measuring devices were incorporated to observe the photons as they passed through the slits.
  • For instance, its interaction with gravity (along with weak and strong nuclear forces) remains a mystery. Unlocking this, and thus discovering a Theory of Everything (ToE) is something astronomers and physicists look forward to. Someday, we just might have it all figured out!

Pandemic-Era Politics Are Ruining Public Education - The Atlantic - 0 views

  • You’re also the nonvoting, perhaps unwitting, subject of adults’ latest pedagogical experiments: either relentless test prep or test abolition; quasi-religious instruction in identity-based virtue and sin; a flood of state laws to keep various books out of your hands and ideas out of your head.
  • Your parents, looking over your shoulder at your education and not liking what they see, have started showing up at school-board meetings in a mortifying state of rage. If you live in Virginia, your governor has set up a hotline where they can rat out your teachers to the government. If you live in Florida, your governor wants your parents to sue your school if it ever makes you feel “discomfort” about who you are
  • Adults keep telling you the pandemic will never end, your education is being destroyed by ideologues, digital technology is poisoning your soul, democracy is collapsing, and the planet is dying—but they’re counting on you to fix everything when you grow up.
  • ...37 more annotations...
  • It isn’t clear how the American public-school system will survive the COVID years. Teachers, whose relative pay and status have been in decline for decades, are fleeing the field. In 2021, buckling under the stresses of the pandemic, nearly 1 million people quit jobs in public education, a 40 percent increase over the previous year.
  • These kids, and the investments that come with them, may never return—the beginning of a cycle of attrition that could continue long after the pandemic ends and leave public schools even more underfunded and dilapidated than before. “It’s an open question whether the public-school system will recover,” Steiner said. “That is a real concern for democratic education.”
  • The high-profile failings of public schools during the pandemic have become a political problem for Democrats, because of their association with unions, prolonged closures, and the pedagogy of social justice, which can become a form of indoctrination.
  • The party that stands for strong government services in the name of egalitarian principles supported the closing of schools far longer than either the science or the welfare of children justified, and it has been woefully slow to acknowledge how much this damaged the life chances of some of America’s most disadvantaged students.
  • Public education is too important to be left to politicians and ideologues. Public schools still serve about 90 percent of children across red and blue America.
  • Since the common-school movement in the early 19th century, the public school has had an exalted purpose in this country. It’s our core civic institution—not just because, ideally, it brings children of all backgrounds together in a classroom, but because it prepares them for the demands and privileges of democratic citizenship. Or at least, it needs to.
  • What is school for? This is the kind of foundational question that arises when a crisis shakes the public’s faith in an essential institution. “The original thinkers about public education were concerned almost to a point of paranoia about creating self-governing citizens,”
  • “Horace Mann went to his grave having never once uttered the phrase college- and career-ready. We’ve become more accustomed to thinking about the private ends of education. We’ve completely lost the habit of thinking about education as citizen-making.”
  • School can’t just be an economic sorting system. One reason we have a stake in the education of other people’s children is that they will grow up to be citizens.
  • Public education is meant not to mirror the unexamined values of a particular family or community, but to expose children to ways that other people, some of them long dead, think.
  • If the answer were simply to push more and more kids into college, the United States would be entering its democratic prime
  • So the question isn’t just how much education, but what kind. Is it quaint, or utopian, to talk about teaching our children to be capable of governing themselves?
  • The COVID era, with Donald Trump out of office but still in power and with battles over mask mandates and critical race theory convulsing Twitter and school-board meetings, shows how badly Americans are able to think about our collective problems—let alone read, listen, empathize, debate, reconsider, and persuade in the search for solutions.
  • democratic citizenship can, at least in part, be learned.
  • The history warriors build their metaphysics of national good or evil on a foundation of ignorance. In a 2019 survey, only 40 percent of Americans were able to pass the test that all applicants for U.S. citizenship must take, which asks questions like “Who did the United States fight in World War II?” and “We elect a President for how many years?” The only state in which a majority passed was Vermont.
  • he orthodoxies currently fighting for our children’s souls turn the teaching of U.S. history into a static and morally simple quest for some American essence. They proceed from celebration or indictment toward a final judgment—innocent or guilty—and bury either oppression or progress in a subordinate clause. The most depressing thing about this gloomy pedagogy of ideologies in service to fragile psyches is how much knowledge it takes away from students who already have so little
  • A central goal for history, social-studies, and civics instruction should be to give students something more solid than spoon-fed maxims—to help them engage with the past on its own terms, not use it as a weapon in the latest front of the culture wars.
  • Releasing them to do “research” in the vast ocean of the internet without maps and compasses, as often happens, guarantees that they will drown before they arrive anywhere.
  • The truth requires a grounding in historical facts, but facts are quickly forgotten without meaning and context
  • The goal isn’t just to teach students the origins of the Civil War, but to give them the ability to read closely, think critically, evaluate sources, corroborate accounts, and back up their claims with evidence from original documents.
  • This kind of instruction, which requires teachers to distinguish between exposure and indoctrination, isn’t easy; it asks them to be more sophisticated professionals than their shabby conditions and pay (median salary: $62,000, less than accountants and transit police) suggest we are willing to support.
  • To do that, we’ll need to help kids restore at least part of their crushed attention spans.
  • staring at a screen for hours is a heavy depressant, especially for teenagers.
  • we’ll look back on the amount of time we let our children spend online with the same horror that we now feel about earlier generations of adults who hooked their kids on smoking.
  • “It’s not a choice between tech or no tech,” Bill Tally, a researcher with the Education Development Center, told me. “The question is what tech infrastructure best enables the things we care about,” such as deep engagement with instructional materials, teachers, and other students.
  • The pandemic should have forced us to reassess what really matters in public school; instead, it’s a crisis that we’ve just about wasted.
  • Like learning to read as historians, learning to sift through the tidal flood of memes for useful, reliable information can emancipate children who have been heedlessly hooked on screens by the adults in their lives
  • Finally, let’s give children a chance to read books—good books. It’s a strange feature of all the recent pedagogical innovations that they’ve resulted in the gradual disappearance of literature from many classrooms.
  • The best way to interest young people in literature is to have them read good literature, and not just books that focus with grim piety on the contemporary social and psychological problems of teenagers.
  • We sell them insultingly short in thinking that they won’t read unless the subject is themselves. Mirrors are ultimately isolating; young readers also need windows, even if the view is unfamiliar, even if it’s disturbing
  • connection through language to universal human experience and thought is the reward of great literature, a source of empathy and wisdom.
  • The culture wars, with their atmosphere of resentment, fear, and petty faultfinding, are hostile to the writing and reading of literature.
  • W. E. B. Du Bois wrote: “Nations reel and stagger on their way; they make hideous mistakes; they commit frightful wrongs; they do great and beautiful things. And shall we not best guide humanity by telling the truth about all this, so far as the truth is ascertainable?”
  • The classroom has become a half-abandoned battlefield, where grown-ups who claim to be protecting students from the virus, from books, from ideologies and counter-ideologies end up using children to protect themselves and their own entrenched camps.
  • American democracy can’t afford another generation of adults who don’t know how to talk and listen and think. We owe our COVID-scarred children the means to free themselves from the failures of the past and the present.
  • Students are leaving as well. Since 2020, nearly 1.5 million children have been removed from public schools to attend private or charter schools or be homeschooled.
  • “COVID has encouraged poor parents to question the quality of public education. We are seeing diminished numbers of children in our public schools, particularly our urban public schools.” In New York, more than 80,000 children have disappeared from city schools; in Los Angeles, more than 26,000; in Chicago, more than 24,000.

Why The CHIPS and Science Act Is a Climate Bill - The Atlantic - 0 views

  • Over the next five years, the CHIPS Act will direct an estimated $67 billion, or roughly a quarter of its total funding, toward accelerating the growth of zero-carbon industries and conducting climate-relevant research, according to an analysis from RMI, a nonpartisan energy think tank based in Colorado.
  • That means that the CHIPS Act is one of the largest climate bills ever passed by Congress. It exceeds the total amount of money that the government spent on renewable-energy tax credits from 2005 to 2019
  • And it’s more than half the size of the climate spending in President Barack Obama’s 2009 stimulus bill. That’s all the more remarkable because the CHIPS Act was passed by large bipartisan majorities, with 41 Republicans and nearly all Democrats supporting it in the House and the Senate.
  • ...15 more annotations...
  • When viewed with the Inflation Reduction Act, which the House is poised to pass later this week, and last year’s bipartisan infrastructure law, a major shift in congressional climate spending comes into focus. According to the RMI analysis, these three laws are set to more than triple the federal government’s average annual spending on climate and clean energy this decade, compared with the 2010s.
  • Within a few years, when the funding has fully ramped up, the government will spend roughly $80 billion a year on accelerating the development and deployment of zero-carbon energy and preparing for the impacts of climate change. That exceeds the GDP of about 120 of the 192 countries that have signed the Paris Agreement on Climate Change
  • By the end of the decade, the federal government will have spent more than $521 billion
  • the bill’s programs focus on the bleeding edge of the decarbonization problem, investing money in technology that should lower emissions in the 2030s and beyond.
  • The International Energy Association has estimated that almost half of global emissions reductions by 2050 will come from technologies that exist only as prototypes or demonstration projects today.
  • To get those technologies ready in time, we need to deploy those new ideas as fast as we can, then rapidly get them to commercial scale, Carey said. “What used to take two decades now needs to take six to 10 years.” That’s what the CHIPS Act is supposed to do
  • The law, for instance, establishes a new $20 billion Directorate for Technology, which will specialize in pushing new technologies from the prototype stage into the mass market. It is meant to prevent what happened with the solar industry—where America invented a new technology, only to lose out on commercializing it—from happening again
  • Congress has explicitly tasked the new office with studying “natural and anthropogenic disaster prevention or mitigation” as well as “advanced energy and industrial efficiency technologies,” including next-generation nuclear reactors.
  • The bill also directs about $12 billion in new research, development, and demonstration funding to the Department of Energy, according to RMI’s estimate. That includes doubling the budget for ARPA-E, the department’s advanced-energy-projects skunk works.
  • it allocates billions to upgrade facilities at the government’s in-house defense and energy research institutes, including the National Renewable Energy Laboratory, the Princeton Plasma Physics Laboratory, and Berkeley Lab, which conducts environmental-science research.
  • RMI’s estimate of the climate spending in the CHIPS bill should be understood as just that: an estimate. The bill text rarely specifies how much of its new funding should go to climate issues.
  • When you add CHIPS, the IRA, and the infrastructure law together, Washington appears to be unifying behind a new industrial policy, focused not only on semiconductors and defense technology but clean energy
  • The three bills combine to form a “a coordinated, strategic policy for accelerating the transition to the technologies that are going to define the 21st century,”
  • scholars and experts have speculated about whether industrial policy—the intentional use of law to nurture and grow certain industries—might make a comeback to help fight climate change. Industrial policy was central to some of the Green New Deal’s original pitch, and it has helped China develop a commanding lead in the global solar industry.
  • “Industrial policy,” he said, “is back.”

So where does the responsibility lie in improving worker safety, and what can be done about it?

The decline effect and the scientific method : The New Yorker - 3 views

  • The test of replicability, as it’s known, is the foundation of modern research. Replicability is how the community enforces itself. It’s a safeguard for the creep of subjectivity. Most of the time, scientists know what results they want, and that can influence the results they get. The premise of replicability is that the scientific community can correct for these flaws.
  • But now all sorts of well-established, multiply confirmed findings have started to look increasingly uncertain. It’s as if our facts were losing their truth: claims that have been enshrined in textbooks are suddenly unprovable.
  • This phenomenon doesn’t yet have an official name, but it’s occurring across a wide range of fields, from psychology to ecology.
  • ...39 more annotations...
  • If replication is what separates the rigor of science from the squishiness of pseudoscience, where do we put all these rigorously validated findings that can no longer be proved? Which results should we believe?
  • Schooler demonstrated that subjects shown a face and asked to describe it were much less likely to recognize the face when shown it later than those who had simply looked at it. Schooler called the phenomenon “verbal overshadowing.”
  • The most likely explanation for the decline is an obvious one: regression to the mean. As the experiment is repeated, that is, an early statistical fluke gets cancelled out. The extrasensory powers of Schooler’s subjects didn’t decline—they were simply an illusion that vanished over time.
  • yet Schooler has noticed that many of the data sets that end up declining seem statistically solid—that is, they contain enough data that any regression to the mean shouldn’t be dramatic. “These are the results that pass all the tests,” he says. “The odds of them being random are typically quite remote, like one in a million. This means that the decline effect should almost never happen. But it happens all the time!
  • this is why Schooler believes that the decline effect deserves more attention: its ubiquity seems to violate the laws of statistics
  • In 2001, Michael Jennions, a biologist at the Australian National University, set out to analyze “temporal trends” across a wide range of subjects in ecology and evolutionary biology. He looked at hundreds of papers and forty-four meta-analyses (that is, statistical syntheses of related studies), and discovered a consistent decline effect over time, as many of the theories seemed to fade into irrelevance.
  • Jennions admits that his findings are troubling, but expresses a reluctance to talk about them
  • publicly. “This is a very sensitive issue for scientists,” he says. “You know, we’re supposed to be dealing with hard facts, the stuff that’s supposed to stand the test of time. But when you see these trends you become a little more skeptical of things.”
  • While publication bias almost certainly plays a role in the decline effect, it remains an incomplete explanation. For one thing, it fails to account for the initial prevalence of positive results among studies that never even get submitted to journals. It also fails to explain the experience of people like Schooler, who have been unable to replicate their initial data despite their best efforts.
  • Jennions, similarly, argues that the decline effect is largely a product of publication bias, or the tendency of scientists and scientific journals to prefer positive data over null results, which is what happens when no effect is found. The bias was first identified by the statistician Theodore Sterling, in 1959, after he noticed that ninety-seven per cent of all published psychological studies with statistically significant data found the effect they were looking for
  • Sterling saw that if ninety-seven per cent of psychology studies were proving their hypotheses, either psychologists were extraordinarily lucky or they published only the outcomes of successful experiments.
  • One of his most cited papers has a deliberately provocative title: “Why Most Published Research Findings Are False.”
  • suspects that an equally significant issue is the selective reporting of results—the data that scientists choose to document in the first place. Palmer’s most convincing evidence relies on a statistical tool known as a funnel graph. When a large number of studies have been done on a single subject, the data should follow a pattern: studies with a large sample size should all cluster around a common value—the true result—whereas those with a smaller sample size should exhibit a random scattering, since they’re subject to greater sampling error. This pattern gives the graph its name, since the distribution resembles a funnel.
  • after Palmer plotted every study of fluctuating asymmetry, he noticed that the distribution of results with smaller sample sizes wasn’t random at all but instead skewed heavily toward positive results. Palmer has since documented a similar problem in several other contested subject areas. “Once I realized that selective reporting is everywhere in science, I got quite depressed,” Palmer told me. “As a researcher, you’re always aware that there might be some nonrandom patterns, but I had no idea how widespread it is.”
  • Palmer summarized the impact of selective reporting on his field: “We cannot escape the troubling conclusion that some—perhaps many—cherished generalities are at best exaggerated in their biological significance and at worst a collective illusion nurtured by strong a-priori beliefs often repeated.”
  • Palmer emphasizes that selective reporting is not the same as scientific fraud. Rather, the problem seems to be one of subtle omissions and unconscious misperceptions, as researchers struggle to make sense of their results. Stephen Jay Gould referred to this as the “sho
  • horning” process.
  • “A lot of scientific measurement is really hard,” Simmons told me. “If you’re talking about fluctuating asymmetry, then it’s a matter of minuscule differences between the right and left sides of an animal. It’s millimetres of a tail feather. And so maybe a researcher knows that he’s measuring a good male”—an animal that has successfully mated—“and he knows that it’s supposed to be symmetrical. Well, that act of measurement is going to be vulnerable to all sorts of perception biases. That’s not a cynical statement. That’s just the way human beings work.”
  • For Simmons, the steep rise and slow fall of fluctuating asymmetry is a clear example of a scientific paradigm, one of those intellectual fads that both guide and constrain research: after a new paradigm is proposed, the peer-review process is tilted toward positive results. But then, after a few years, the academic incentives shift—the paradigm has become entrenched—so that the most notable results are now those that disprove the theory.
  • John Ioannidis, an epidemiologist at Stanford University, argues that such distortions are a serious issue in biomedical research. “These exaggerations are why the decline has become so common,” he says. “It’d be really great if the initial studies gave us an accurate summary of things. But they don’t. And so what happens is we waste a lot of money treating millions of patients and doing lots of follow-up studies on other themes based on results that are misleading.”
  • In 2005, Ioannidis published an article in the Journal of the American Medical Association that looked at the forty-nine most cited clinical-research studies in three major medical journals.
  • the data Ioannidis found were disturbing: of the thirty-four claims that had been subject to replication, forty-one per cent had either been directly contradicted or had their effect sizes significantly downgraded.
  • the most troubling fact emerged when he looked at the test of replication: out of four hundred and thirty-two claims, only a single one was consistently replicable. “This doesn’t mean that none of these claims will turn out to be true,” he says. “But, given that most of them were done badly, I wouldn’t hold my breath.”
  • According to Ioannidis, the main problem is that too many researchers engage in what he calls “significance chasing,” or finding ways to interpret the data so that it passes the statistical test of significance—the ninety-five-per-cent boundary invented by Ronald Fisher.
  • One of the classic examples of selective reporting concerns the testing of acupuncture in different countries. While acupuncture is widely accepted as a medical treatment in various Asian countries, its use is much more contested in the West. These cultural differences have profoundly influenced the results of clinical trials.
  • The problem of selective reporting is rooted in a fundamental cognitive flaw, which is that we like proving ourselves right and hate being wrong.
  • “It feels good to validate a hypothesis,” Ioannidis said. “It feels even better when you’ve got a financial interest in the idea or your career depends upon it. And that’s why, even after a claim has been systematically disproven”—he cites, for instance, the early work on hormone replacement therapy, or claims involving various vitamins—“you still see some stubborn researchers citing the first few studies
  • That’s why Schooler argues that scientists need to become more rigorous about data collection before they publish. “We’re wasting too much time chasing after bad studies and underpowered experiments,”
  • The current “obsession” with replicability distracts from the real problem, which is faulty design.
  • “Every researcher should have to spell out, in advance, how many subjects they’re going to use, and what exactly they’re testing, and what constitutes a sufficient level of proof. We have the tools to be much more transparent about our experiments.”
  • Schooler recommends the establishment of an open-source database, in which researchers are required to outline their planned investigations and document all their results. “I think this would provide a huge increase in access to scientific work and give us a much better way to judge the quality of an experiment,”
  • scientific research will always be shadowed by a force that can’t be curbed, only contained: sheer randomness. Although little research has been done on the experimental dangers of chance and happenstance, the research that exists isn’t encouraging.
  • The disturbing implication of the Crabbe study is that a lot of extraordinary scientific data are nothing but noise. The hyperactivity of those coked-up Edmonton mice wasn’t an interesting new fact—it was a meaningless outlier, a by-product of invisible variables we don’t understand.
  • The problem, of course, is that such dramatic findings are also the most likely to get published in prestigious journals, since the data are both statistically significant and entirely unexpected
  • This suggests that the decline effect is actually a decline of illusion. While Karl Popper imagined falsification occurring with a single, definitive experiment—Galileo refuted Aristotelian mechanics in an afternoon—the process turns out to be much messier than that.
  • Many scientific theories continue to be considered true even after failing numerous experimental tests.
  • Even the law of gravity hasn’t always been perfect at predicting real-world phenomena. (In one test, physicists measuring gravity by means of deep boreholes in the Nevada desert found a two-and-a-half-per-cent discrepancy between the theoretical predictions and the actual data.)
  • Such anomalies demonstrate the slipperiness of empiricism. Although many scientific ideas generate conflicting results and suffer from falling effect sizes, they continue to get cited in the textbooks and drive standard medical practice. Why? Because these ideas seem true. Because they make sense. Because we can’t bear to let them go. And this is why the decline effect is so troubling. Not because it reveals the human fallibility of science, in which data are tweaked and beliefs shape perceptions. (Such shortcomings aren’t surprising, at least for scientists.) And not because it reveals that many of our most exciting theories are fleeting fads and will soon be rejected. (That idea has been around since Thomas Kuhn.)
  • The decline effect is troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that’s often not the case. Just because an idea is true doesn’t mean it can be proved. And just because an idea can be proved doesn’t mean it’s true. When the experiments are done, we still have to choose what to believe. ♦
