History News Network | History Gets Into Bed with Psychology, and It's a Happy Match - 0 views

  • The fact that many of our self-protective delusions are built into the way the brain works is no justification for not trying to override them. Knowing how dissonance works helps us identify our own inclinations to perpetuate errors -- and protect ourselves from those who can’t.

  • at last, history has gotten into bed with psychological science, and it’s a happy match. History gives us the data of, in Barbara Tuchman’s splendid words, our march of folly -- repeated examples of human beings unable and unwilling to learn from mistakes, let alone to admit them. Cognitive science shows us why
  • Our brains, which have allowed us to travel into outer space, have a whole bunch of design flaws, which is why we have so much breathtaking bumbling here on Earth.

  • Of the many built-in biases in human thought, three have perhaps the greatest consequences for our own history and that of nations: the belief that we see things as they really are, rather than as we wish them to be; the belief that we are better, kinder, smarter, and more ethical than average; and the confirmation bias, which sees to it that we notice, remember, and accept information that confirms our beliefs -- and overlook, forget, and discount information that disconfirms our beliefs.
  • The great motivational theory that accommodates all of these biases is cognitive dissonance, developed by Leon Festinger in 1957 and further refined and transformed into a theory of self-justification by his student (and later my coauthor and friend) Elliot Aronson. The need to reduce dissonance is the key mechanism that underlies the reluctance to be wrong, to change our minds, to admit serious mistakes, and to be unwilling to accept unwelcome information
  • The greater the dissonance between who we are and the mistake we made or the cruelty we committed, the greater the need to justify the mistake, the crime, the villainy, instead of admitting and rectifying it

Stanford Magazine - History Detected - May/June 2013 - 2 views

  • an approach developed at Stanford's Graduate School of Education that's rapidly gaining adherents across the country
  • trial studies of the Stanford program demonstrated that when high school students engage regularly with challenging primary source documents, they not only make significant gains learning and retaining historical material, they also markedly improve their reading comprehension and critical thinking.
  • Colglazier builds his thought-provoking classes using an online tool called Reading Like a Historian. Designed by the Stanford History Education Group under Professor Sam Wineburg, the website offers 87 flexible lesson plans featuring documents from the Library of Congress
  • ...15 more annotations...
  • "Textbooks are useful as background narrative. It's difficult to talk about the Gulf of Tonkin Resolution if students don't know where Vietnam is, or the Lincoln-Douglas debates if they don't know who Abe Lincoln was before he was Daniel Day-Lewis.
  • The website's lessons have been downloaded 800,000 times and spawned a lively online community of history educators grateful for the camaraderie
  • just 30 percent of the people who teach history-related courses in U.S. public high schools both majored in the field and are certified to teach it.
  • " By reading these challenging documents and discovering history for themselves, he says, "not only will they remember the content, they'll develop skills for life."
  • Teachers can download the lessons and adapt them for their own purposes, free of charge. Students learn how to examine documents critically, just as historians would, in order to answer intriguing questions: Did Pocahontas really rescue John Smith? Was Abraham Lincoln a racist? Who blinked first in the Cuban Missile Crisis, the Russians or the Americans?
  • But when a ten-pound textbook becomes the script for a whole year's worth of instruction, a precious learning opportunity is lost. "Many students go through their entire middle and high school and never encounter the actual voice of a historical participant,"
  • The Common Core curriculum will bring radical changes in the standardized state tests that youngsters have been taking for decades. Instead of filling in multiple-choice bubbles, they will be expected to write out short answers that demonstrate their ability to analyze texts, and then cite those texts to support arguments—the exact skills that Reading Like a Historian fosters.
  • Wineburg realized that the art of historical thinking is not something that comes naturally to most people; it has to be cultivated. Students have to be taught to look at the source of a document before reading it, figure out the context in which it was written, and cross-check it with other sources before coming to a conclusion.
  • In 2008, Reisman was ready to conduct a test of the curriculum at five schools in the San Francisco Unified School District. As expected, students in the test classes showed an increased ability to retain historical knowledge, as well as a greater appreciation for history, compared to the control group. What took everyone by surprise, though, was how much the test students advanced in basic reading.
  • Fremont 11th grader Ayanna Black agrees. "In other history courses I have taken, I wasn't able to fully understand what was going on. It seemed that it was just a bunch of words I had to memorize for a future test," she says. "Now that I contextualize the information I am given, it helps me understand not only what is being said but also the reason behind it." The approach, she says, "leads me to remembering the information out of curiosity, rather than trying to pass a test."
  • Scholars in the Stanford History Education Group hope to develop more online lesson plans in world history
  • Wineburg devoured history books as a kid and did well in Advanced Placement courses at his public high school. But when he entered Brown University, he was shocked at how ill-prepared he was in the subject. Employed after college as a high school history teacher, he saw similar weaknesses in his students. "The best ones could repeat what the text said," he recalls, "but when I asked them to critically examine whether they believed the text, I could have been speaking Martian."
  • Wineburg and his PhD students have teamed up with the library on another project: a website called Beyond the Bubble,where teachers can learn how to evaluate their students using short written tests called History Assessments of Thinking. Each HAT asks students to consider a historical document—a letter drawn from the archives of the NAACP, for example—and justify their conclusions about it in three or four sentences. By scanning the responses, teachers can determine quickly whether their pupils are grasping basic concepts.
  • Wineburg hopes to make Reading Like a Historian lesson plans completely paperless, with exercise sheets that can be filled out on a laptop or tablet computer.
  • Though the work has been hard in history this year, she appreciates what it's taught her. "I've learned that you don't just read what is put in front of you and accept it, which is what I had been doing with my textbook all summer," she explains. "It can be frustrating to analyze documents that are contradictory, but I'm coming to appreciate that history is a collection of thousands of accounts and perspectives, and it's our job to interpret it."

  • First, making a choice is physically exhausting, literally, so that somebody forced to make a number of decisions in a row is likely to get lazy and dumb.
  • Second, having too many choices can make us less likely to come to a conclusion. In a famous study of the so-called "paradox of choice", psychologists Mark Lepper and Sheena Iyengar found that customers presented with six jam varieties were more likely to buy one than customers offered a choice of 24.
  • ...7 more annotations...
  • Many of our mistakes stem from a central "availability bias." Our brains are computers, and we like to access recently opened files, even though many decisions require a deep body of information that might require some searching. Cheap example: We remember the first, last, and peak moments of certain experiences.
  • The third check against the theory of the rational consumer is the fact that we're social animals. We let our friends and family and tribes do our thinking for us
  • neurologists are finding that many of the biases behavioral economists perceive in decision-making start in our brains. "Brain studies indicate that organisms seem to be on a hedonic treadmill, quickly habituating to homeostasis," McFadden writes. In other words, perhaps our preference for the status quo isn't just figuratively our heads, but also literally sculpted by the hand of evolution inside of our brains.
  • The popular psychological theory of "hyperbolic discounting" says people don't properly evaluate rewards over time. The theory seeks to explain why many groups -- nappers, procrastinators, Congress -- take rewards now and pain later, over and over again. But neurology suggests that it hardly makes sense to speak of "the brain," in the singular, because it's two very different parts of the brain that process choices for now and later. The choice to delay gratification is mostly processed in the frontal system. But studies show that the choice to do something immediately gratifying is processed in a different system, the limbic system, which is more viscerally connected to our behavior, our "reward pathways," and our feelings of pain and pleasure.
  • the final message is that neither the physiology of pleasure nor the methods we use to make choices are as simple or as single-minded as the classical economists thought. A lot of behavior is consistent with pursuit of self-interest, but in novel or ambiguous decision-making environments there is a good chance that our habits will fail us and inconsistencies in the way we process information will undo us.
  • Our brains seem to operate like committees, assigning some tasks to the limbic system, others to the frontal system. The "switchboard" does not seem to achieve complete, consistent communication between different parts of the brain. Pleasure and pain are experienced in the limbic system, but not on one fixed "utility" or "self-interest" scale. Pleasure and pain have distinct neural pathways, and these pathways adapt quickly to homeostasis, with sensation coming from changes rather than levels
  • Social networks are sources of information, on what products are available, what their features are, and how your friends like them. If the information is accurate, this should help you make better choices. On the other hand, it also makes it easier for you to follow the crowd rather than engaging in the due diligence of collecting and evaluating your own information and playing it against your own preferences

Do Political Experts Know What They're Talking About? | Wired Science | Wired... - 1 views

  • I often joke that every cable news show should be forced to display a disclaimer, streaming in a loop at the bottom of the screen. The disclaimer would read: “These talking heads have been scientifically proven to not know what they are talking about. Their blather is for entertainment purposes only.” The viewer would then be referred to Tetlock’s most famous research project, which began in 1984.
  • He picked a few hundred political experts – people who made their living “commenting or offering advice on political and economic trends” – and began asking them to make predictions about future events. He had a long list of pertinent questions. Would George Bush be re-elected? Would there be a peaceful end to apartheid in South Africa? Would Quebec secede from Canada? Would the dot-com bubble burst? In each case, the pundits were asked to rate the probability of several possible outcomes. Tetlock then interrogated the pundits about their thought process, so that he could better understand how they made up their minds.
  • Most of Tetlock’s questions had three possible answers; the pundits, on average, selected the right answer less than 33 percent of the time. In other words, a dart-throwing chimp would have beaten the vast majority of professionals. These results are summarized in his excellent Expert Political Judgment.
  • ...5 more annotations...
  • Some experts displayed a top-down style of reasoning: politics as a deductive art. They started with a big-idea premise about human nature, society, or economics and applied it to the specifics of the case. They tended to reach more confident conclusions about the future. And the positions they reached were easier to classify ideologically: that is the Keynesian prediction and that is the free-market fundamentalist prediction and that is the worst-case environmentalist prediction and that is the best case technology-driven growth prediction etc. Other experts displayed a bottom-up style of reasoning: politics as a much messier inductive art. They reached less confident conclusions and they are more likely to draw on a seemingly contradictory mix of ideas in reaching those conclusions (sometimes from the left, sometimes from the right). We called the big-idea experts “hedgehogs” (they know one big thing) and the more eclectic experts “foxes” (they know many, not so big things).
  • The most consistent predictor of consistently more accurate forecasts was “style of reasoning”: experts with the more eclectic, self-critical, and modest cognitive styles tended to outperform the big-idea people (foxes tended to outperform hedgehogs).
  • Lehrer: Can non-experts do anything to encourage a more effective punditocracy?
  • Tetlock: Yes, non-experts can encourage more accountability in the punditocracy. Pundits are remarkably skillful at appearing to go out on a limb in their claims about the future, without actually going out on one. For instance, they often “predict” continued instability and turmoil in the Middle East (predicting the present) but they virtually never get around to telling you exactly what would have to happen to disconfirm their expectations. They are essentially impossible to pin down. If pundits felt that their public credibility hinged on participating in level playing field forecasting exercises in which they must pit their wits against an extremely difficult-to-predict world, I suspect they would be learn, quite quickly, to be more flexible and foxlike in their policy pronouncements.

Naomi Oreskes, a Lightning Rod in a Changing Climate - The New York Times - 0 views

  • Dr. Oreskes is fast becoming one of the biggest names in climate science — not as a climatologist, but as a defender who uses the tools of historical scholarship to counter what she sees as ideologically motivated attacks on the field.
  • Formally, she is a historian of science
  • Dr. Oreskes’s approach has been to dig deeply into the history of climate change denial, documenting its links to other episodes in which critics challenged a developing scientific consensus.
  • ...20 more annotations...
  • Her core discovery, made with a co-author, Erik M. Conway, was twofold. They reported that dubious tactics had been used over decades to cast doubt on scientific findings relating to subjects like acid rain, the ozone shield, tobacco smoke and climate change. And most surprisingly, in each case, the tactics were employed by the same group of people.
  • The central players were serious scientists who had major career triumphs during the Cold War, but in subsequent years apparently came to equate environmentalism with socialism, and government regulation with tyranny.
  • In a 2010 book, Dr. Oreskes and Dr. Conway called these men “Merchants of Doubt,” and this spring the book became a documentary film, by Robert Kenner. At the heart of both works is a description of methods that were honed by the tobacco industry in the 1960s and have since been employed to cast doubt on just about any science being cited to support new government regulations.
  • Dr. Oreskes, the more visible and vocal of the “Merchants” authors, has been threatened with lawsuits and vilified on conservative websites, and routinely gets hate mail calling her a communist or worse.
  • She established her career as a historian with a book-length study examining the role of dissent in the scientific method. As she put it a few months ago to an audience at Indiana University, she wanted to wrestle with this question: “How do you distinguish a maverick from a crank?”
  • Dr. Oreskes found that Wegener had been treated badly, particularly by American geologists. But he did not abandon his faith in the scientific method. He kept publishing until his death in 1930, trying to convince fellow scientists of his position, and was finally vindicated three decades later by oceanographic research conducted during the Cold War.
  • As she completed that study, Dr. Oreskes sought to understand how science was affected not only by the Cold War but by its end. In particular, she started wondering about climate science. Global warming had seemed to rise as an important issue around the time the Iron Curtain came down. Was this just a way for scientists to scare up research money that would no longer be coming their way through military channels?
  • the widespread public impression was that scientists were still divided over whether humans were primarily responsible for the warming of the planet. But how sharp was the split, she wondered?
  • She decided to do something no climate scientist had thought to do: count the published scientific papers. Pulling 928 of them, she was startled to find that not one dissented from the basic findings that warming was underway and human activity was the main reason.
  • She published that finding in a short paper in the journal Science in 2004, and the reaction was electric. Advocates of climate action seized on it as proof of a level of scientific consensus that most of them had not fully perceived. Just as suddenly, Dr. Oreskes found herself under political attack.
  • Some of the voices criticizing her — scientists like Dr. Singer and groups like the George C. Marshall Institute in Washington — were barely known to her at the time, Dr. Oreskes said in an interview. Just who were they?
  • It did not take them long to document that this group, which included prominent Cold War scientists, had been attacking environmental research for decades, challenging the science of the ozone layer and acid rain, even the finding that breathing secondhand tobacco smoke was harmful. Trying to undermine climate science was simply the latest project.
  • Dr. Oreskes and Dr. Conway came to believe that the attacks were patterned on the strategy employed by the tobacco industry when evidence of health risks first emerged. Documents pried loose by lawyers showed that the industry had paid certain scientists to contrive dubious research, had intimidated reputable scientists, and had cherry-picked evidence to present a misleading pictur
  • The tobacco industry had used these tactics in defense of profits. But Dr. Oreskes and Dr. Conway wrote that the so-called merchants of doubt had adopted them for a deep ideological reason: contempt for government regulation. The insight gave climate scientists a new way of understanding the politics that had engulfed their field.
  • Following Dr. Oreskes’s cue, researchers have in recent years developed a cottage industry of counting scientific papers and polling scientists. The results typically show that about 97 percent of working climate scientists accept that global warming is happening, that humans are largely responsible, and that the situation poses long-term risks, though the severity of those risks is not entirely clear. That wave of evidence has prompted many national news organizations to stop portraying the field as split evenly between scientists who are convinced and unconvinced.
  • Dr. Oreskes’s critics have taken delight in searching out errors in her books and other writings, prompting her to post several corrections. They have generally been minor, though, like describing a pH of six as neutral, when the correct number is seven. Dr. Oreskes described that as a typographical error.
  • In the leaked emails, Dr. Singer told a group of his fellow climate change denialists that he felt that Dr. Oreskes and Dr. Conway had libeled him. But in an interview, when pressed for specific errors in the book that might constitute libel, he listed none. Nor did he provide such a list in response to a follow-up email request.
  • However much she might be hated by climate change denialists, Dr. Oreskes is often welcomed on college campuses these days. She usually outlines the decades of research supporting the idea that human emissions pose serious risks.
  • “One of the things that should always be asked about scientific evidence is, how old is it?” Dr. Oreskes said. “It’s like wine. If the science about climate change were only a few years old, I’d be a skeptic, too.”
  • Dr. Oreskes and Dr. Conway keep looking for ways to reach new audiences. Last year, they published a short work of science fiction, written as a historical essay from the distant future. “The Collapse of Western Civilization: A View From the Future” argues that conservatives, by fighting sensible action to cope with the climate crisis, are essentially guaranteeing the long-term outcome they fear, a huge expansion of government.

Is Facebook Bad for You? It Is for About 360 Million Users, Company Surveys Suggest - WSJ - 0 views

  • Facebook FB 1.57% researchers have found that 1 in 8 of its users report engaging in compulsive use of social media that impacts their sleep, work, parenting or relationships, according to documents reviewed by The Wall Street Journal.
  • These patterns of what the company calls problematic use mirror what is popularly known as internet addiction. They were perceived by users to be worse on Facebook than any other major social-media platform
  • A Facebook team focused on user well-being suggested a range of fixes, and the company implemented some, building in optional features to encourage breaks from social media and to dial back the notifications that can serve as a lure to bring people back to the platform.
  • ...25 more annotations...
  • Facebook shut down the team in late 2019.
  • “We have a role to play, which is why we’ve built tools and controls to help people manage when and how they use our services,” she said in the statement. “Furthermore, we have a dedicated team working across our platforms to better understand these issues and ensure people are using our apps in ways that are meaningful to them.”
  • They wrote that they don’t consider the behavior to be a clinical addiction because it doesn’t affect the brain in the same way as gambling or substance abuse. In one document, they noted that “activities like shopping, sex and Facebook use, when repetitive and excessive, may cause problems for some people.”
  • In March 2020, several months after the well-being team was dissolved, researchers who had been on the team shared a slide deck internally with some of the findings and encouraged other teams to pick up the work.
  • The researchers estimated these issues affect about 12.5% of the flagship app’s more than 2.9 billion users, or more than 360 million people. About 10% of users in the U.S., one of Facebook’s most lucrative markets, exhibit this behavior
  • In the Philippines and in India, which is the company’s largest market, the employees put the figure higher, at around 25%.
  • “Why should we care?” the researchers wrote in the slide deck. “People perceive the impact. In a comparative study with competitors, people perceived lower well-being and higher problematic use on Facebook compared to any other service.
  • Facebook’s findings are consistent with what many external researchers have observed for years,
  • said Brian Primack, a professor of public health and medicine and dean of the College of Education and Health Professions at the University of Arkansas
  • His research group followed about a thousand people over six months in a nationally representative survey and found that the amount of social media that a person used was the No. 1 predictor of the variables they measured for who became depressed.
  • In late 2017, a Facebook executive and a researcher wrote a public blog post that outlined some of the issues with social-media addiction. According to the post, the company had found that while passive consumption of social media could make you feel worse, the opposite was true of more active social-media use.
  • Inside Facebook, the researchers registered concern about the direction of Facebook’s focus on certain metrics, including the number of times a person logs into the app, which the company calls a session. “One of the worries with using sessions as a north star is we want to be extra careful not to game them by creating bad experiences for vulnerable populations,” a researcher wrote, referring to elements designed to draw people back to Facebook frequently, such as push notifications.
  • Facebook then made a switch to more heavily weigh “meaningful social interactions” in its news feed as a way to combat passive consumption. One side effect of that change, as outlined in a previous Journal article in The Facebook Files, was that the company’s algorithms rewarded content that was angry or sensational, because those posts increased engagement from users.
  • Facebook said any algorithm can promote objectionable or harmful content and that the company is doing its best to mitigate the problem.
  • “Every second that I wasn’t occupied by something I had to do I was fooling around on my phone scrolling through Facebook,” Ms. Gandy said. “Facebook took over my brain.”
  • “Actively interacting with people—especially sharing messages, posts and comments with close friends and reminiscing about past interactions—is linked to improvements in well-being,” the company said.
  • The well-being team, according to people familiar with the matter, was reshuffled at least twice since late 2017 before it was disbanded, and could get only about half of the resources the team requested to do its work.
  • In 2018, Facebook’s researchers surveyed 20,000 U.S. users and paired their answers with data about their behavior on Facebook. The researchers found about 3% of these users said they experienced “serious problems” in their sleep, work or relationships related to their time on Facebook that they found difficult to change. Some of the researchers’ work was published in a 2019 paper.
  • According to that study, the researchers also said that a liberal interpretation of the results would be that 14% of respondents spent “a lot more time on Facebook than they want to,” although they didn’t label this group problematic users.
  • In 2019, the researchers had come to a new figure: What they called problematic use affects 12.5% of people on Facebook, they said. This survey used a broader definition for the issue, including users who reported negative results on key aspects of their life as well as feelings of guilt or a loss of control, according to the documents.
  • The researchers also asked Facebook users what aspects of Facebook triggered them most. The users said the app’s many notifications sucked them in. “Red dots are toxic on the home screen,” a male young adult in the U.S. told the researchers, referring to the symbol that alerts a user to new content.
  • One entrepreneur came up with his own solution to some of these issues. In 2016, software developer Louis Barclay manually unfollowed all the people, pages and groups he saw on Facebook in an attempt to be more deliberate about how he used technology. The process, which isn’t the same as unfriending, took him days, but he was happy with the result: an empty newsfeed that no longer sucked him in for hours. He could still visit the profile pages of everyone he wanted to connect with on Facebook, but their content would no longer appear in the never-ending scroll of posts.
  • Thinking other people might benefit from a similar experience on Facebook, he built a tool that would enable anyone to automate the process. He created it as a piece of add-on software called a browser extension that anyone could download. He called it Unfollow Everything and made it available on Chrome’s web store free of charge.

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. ♦

The Story Behind the SAT Overhaul - NYTimes.com - 2 views

  • “When you cover too many topics,” Coleman said, “the assessments designed to measure those standards are inevitably superficial.” He pointed to research showing that more students entering college weren’t prepared and were forced into “remediation programs from which they never escape.” In math, for example, if you examined data from top-performing countries, you found an approach that emphasized “far fewer topics, far deeper,” the opposite of the curriculums he found in the United States, which he described as “a mile wide and an inch deep.”
  • The lessons he brought with him from thinking about the Common Core were evident — that American education needed to be more focused and less superficial, and that it should be possible to test the success of the newly defined standards through an exam that reflected the material being taught in the classroom.
  • she and her team had extensive conversations with students, teachers, parents, counselors, admissions officers and college instructors, asking each group to tell them in detail what they wanted from the test. What they arrived at above all was that a test should reflect the most important skills that were imparted by the best teachers
  • ...12 more annotations...
  • for example, a good instructor would teach Martin Luther King Jr.’s “I Have a Dream” speech by encouraging a conversation that involved analyzing the text and identifying the evidence, both factual and rhetorical, that makes it persuasive. “The opposite of what we’d want is a classroom where a teacher might ask only: ‘What was the year the speech was given? Where was it given?’ ”
  • in the past, assembling the SAT focused on making sure the questions performed on technical grounds, meaning: Were they appropriately easy or difficult among a wide range of students, and were they free of bias when tested across ethnic, racial and religious subgroups? The goal was “maximizing differentiation” among kids, which meant finding items that were answered correctly by those students who were expected to get them right and incorrectly by the weaker students. A simple way of achieving this, Coleman said, was to test the kind of obscure vocabulary words for which the SAT was famous
  • In redesigning the test, the College Board shifted its emphasis. It prioritized content, measuring each question against a set of specifications that reflect the kind of reading and math that students would encounter in college and their work lives. Schmeiser and others then spent much of early last year watching students as they answered a set of 20 or so problems, discussing the questions with the students afterward. “The predictive validity is going to come out the same,” she said of the redesigned test. “But in the new test, we have much more control over the content and skills that are being measured.”
  • Evidence-based reading and writing, he said, will replace the current sections on reading and writing. It will use as its source materials pieces of writing — from science articles to historical documents to literature excerpts — which research suggests are important for educated Americans to know and understand deeply. “The Declaration of Independence, the Constitution, the Bill of Rights and the Federalist Papers,” Coleman said, “have managed to inspire an enduring great conversation about freedom, justice, human dignity in this country and the world” — therefore every SAT will contain a passage from either a founding document or from a text (like Lincoln’s Gettysburg Address) that is part of the “great global conversation” the founding documents inspired.
  • The Barbara Jordan vocabulary question would have a follow-up — “How do you know your answer is correct?” — to which students would respond by identifying lines in the passage that supported their answer.
  • The idea is that the test will emphasize words students should be encountering, like “synthesis,” which can have several meanings depending on their context. Instead of encouraging students to memorize flashcards, the test should promote the idea that they must read widely throughout their high-school years.
  • . No longer will it be good enough to focus on tricks and trying to eliminate answer choices. We are not interested in students just picking an answer, but justifying their answers.”
  • the essay portion of the test will also be reformulated so that it will always be the same, some version of: “As you read the passage in front of you, consider how the author uses evidence such as facts or examples; reasoning to develop ideas and to connect claims and evidence; and stylistic or persuasive elements to add power to the ideas expressed. Write an essay in which you explain how the author builds an argument to persuade an audience.”
  • The math section, too, will be predicated on research that shows that there are “a few areas of math that are a prerequisite for a wide range of college courses” and careers. Coleman conceded that some might treat the news that they were shifting away from more obscure math problems to these fewer fundamental skills as a dumbing-down the test, but he was adamant that this was not the case. He explained that there will be three areas of focus: problem solving and data analysis, which will include ratios and percentages and other mathematical reasoning used to solve problems in the real world; the “heart of algebra,” which will test how well students can work with linear equations (“a powerful set of tools that echo throughout many fields of study”); and what will be called the “passport to advanced math,” which will focus on the student’s familiarity with complex equations and their applications in science and social science.
  • “Sometimes in the past, there’s been a feeling that tests were measuring some sort of ineffable entity such as intelligence, whatever that might mean. Or ability, whatever that might mean. What this is is a clear message that good hard work is going to pay off and achievement is going to pay off. This is one of the most significant developments that I have seen in the 40-plus years that I’ve been working in admissions in higher education.”
  • The idea of creating a transparent test and then providing a free website that any student could use — not to learn gimmicks but to get a better grounding and additional practice in the core knowledge that would be tested — was appealing to Coleman.
  • (The College Board won’t pay Khan Academy.) They talked about a hypothetical test-prep experience in which students would log on to a personal dashboard, indicate that they wanted to prepare for the SAT and then work through a series of preliminary questions to demonstrate their initial skill level and identify the gaps in their knowledge. Khan said he could foresee a way to estimate the amount of time it would take to achieve certain benchmarks. “It might go something like, ‘O.K., we think you’ll be able to get to this level within the next month and this level within the next two months if you put in 30 minutes a day,’ ” he said. And he saw no reason the site couldn’t predict for anyone, anywhere the score he or she might hope to achieve with a commitment to a prescribed amount of work.

  • although Instagram now has 2 billion monthly users, it faces an existential problem: What happens when the 18-to-29-year-olds who are most likely to use the app, at least in America, age out or go elsewhere? Last year, The New York Times reported that Instagram was privately worried about attracting and retaining the new young users that would sustain its long-term growth—not to mention whose growing shopping potential is catnip to advertisers.
  • Over the summer, these frustrations boiled over. An update that promised, among other things, algorithmically recommended video content that would fill the entire screen was a bridge too far. Users were fed up with watching the app contort itself into a TikTok copycat that prioritized video and recommended posts over photos from friends

Internal documents obtained by The Wall Street Journal show that Instagram users spend 17.6 million hours a day watching Reels, Instagram’s TikTok knockoff, compared with the 197.8 million hours people spend watching TikTok every day. The documents also revealed that Reels engagement has declined by 13.6 percent in recent months, with most users generating “no engagement whatsoever.”
  • Instagram may not be on its deathbed, but its transformation from cool to cringe is a sea change in the social-media universe. The platform was perhaps the most significant among an old generation of popular apps that embodied the original purpose of social media: to connect online with friends and family. Its decline is about not just a loss of relevance, but a capitulation to a new era of “performance” media, in which we create online primarily to reach people we don’t know instead of the people we do
  • . Lavish brand deals, in which an influencer promotes a brand’s product to their audience for a fee, have been known to pay anywhere from $100 to $10,000 per post, depending on the size of the creator’s following and their engagement. Now Tilghman, who became an Instagram influencer in 2015 and at one point had close to 400,000 followers, says she’s seen her rate go down by 80 percent over the past five years. The market’s just oversaturated.
  • The author Jessica DeFino, who joined Instagram in 2018 on the advice of publishing agents, similarly began stepping back from the platform in 2020, feeling overwhelmed by the constant feedback of her following. She has now set up auto-replies to her Instagram DMs: If one of her 59,000 followers sends her a message, they’re met with an invitation to instead reach out to DeFino via email.
  • would she get back on Instagram as a regular user? Only if she “created a private, personal account — somewhere I could limit my interactions to just family and friends,” she says. “Like what Instagram was in the beginning, I guess.”
  • That is if, by then, Instagram’s algorithm-driven, recommendation-fueled, shopping-heavy interface would even let her. Ick.

His Job Was to Make Instagram Safe for Teens. His 14-Year-Old Showed Him What the App W... - 0 views

  • The experience of young users on Meta’s Instagram—where Bejar had spent the previous two years working as a consultant—was especially acute. In a subsequent email to Instagram head Adam Mosseri, one statistic stood out: One in eight users under the age of 16 said they had experienced unwanted sexual advances on the platform over the previous seven days.
  • For Bejar, that finding was hardly a surprise. His daughter and her friends had been receiving unsolicited penis pictures and other forms of harassment on the platform since the age of 14, he wrote, and Meta’s systems generally ignored their reports—or responded by saying that the harassment didn’t violate platform rules.
  • “I asked her why boys keep doing that,” Bejar wrote to Zuckerberg and his top lieutenants. “She said if the only thing that happens is they get blocked, why wouldn’t they?”
  • ...39 more annotations...
  • For the well-being of its users, Bejar argued, Meta needed to change course, focusing less on a flawed system of rules-based policing and more on addressing such bad experiences
  • The company would need to collect data on what upset users and then work to combat the source of it, nudging those who made others uncomfortable to improve their behavior and isolating communities of users who deliberately sought to harm others.
  • “I am appealing to you because I believe that working this way will require a culture shift,” Bejar wrote to Zuckerberg—the company would have to acknowledge that its existing approach to governing Facebook and Instagram wasn’t working.
  • During and after Bejar’s time as a consultant, Meta spokesman Andy Stone said, the company has rolled out several product features meant to address some of the Well-Being Team’s findings. Those features include warnings to users before they post comments that Meta’s automated systems flag as potentially offensive, and reminders to be kind when sending direct messages to users like content creators who receive a large volume of messages.&nbsp;
  • Meta’s classifiers were reliable enough to remove only a low single-digit percentage of hate speech with any degree of precision.
  • Bejar was floored—all the more so when he learned that virtually all of his daughter’s friends had been subjected to similar harassment. “DTF?” a user they’d never met would ask, using shorthand for a vulgar proposition. Instagram acted so rarely on reports of such behavior that the girls no longer bothered reporting them.&nbsp;
  • Meta’s own statistics suggested that big problems didn’t exist.&nbsp;
  • Meta had come to approach governing user behavior as an overwhelmingly automated process. Engineers would compile data sets of unacceptable content—things like terrorism, pornography, bullying or “excessive gore”—and then train machine-learning models to screen future content for similar material.
  • While users could still flag things that upset them, Meta shifted resources away from reviewing them. To discourage users from filing reports, internal documents from 2019 show, Meta added steps to the reporting process. Meta said the changes were meant to discourage frivolous reports and educate users about platform rules.&nbsp;
  • The outperformance of Meta’s automated enforcement relied on what Bejar considered two sleights of hand. The systems didn’t catch anywhere near the majority of banned content—only the majority of what the company ultimately removed
  • “Please don’t talk about my underage tits,” Bejar’s daughter shot back before reporting his comment to Instagram. A few days later, the platform got back to her: The insult didn’t violate its community guidelines.
  • Also buttressing Meta’s statistics were rules written narrowly enough to ban only unambiguously vile material. Meta’s rules didn’t clearly prohibit adults from flooding the comments section on a teenager’s posts with kiss emojis or posting pictures of kids in their underwear, inviting their followers to “see more” in a private Facebook Messenger group.&nbsp;
  • “Mark personally values freedom of expression first and foremost and would say this is a feature and not a bug,” Rosen responded
  • Narrow rules and unreliable automated enforcement systems left a lot of room for bad behavior—but they made the company’s child-safety statistics look pretty good according to Meta’s metric of choice: prevalence.
  • Defined as the percentage of content viewed worldwide that explicitly violates a Meta rule, prevalence was the company’s preferred measuring stick for the problems users experienced.
  • According to prevalence, child exploitation was so rare on the platform that it couldn’t be reliably estimated, less than 0.05%, the threshold for functional measurement. Content deemed to encourage self-harm, such as eating disorders, was just as minimal, and rule violations for bullying and harassment occurred in just eight of 10,000 views.&nbsp;
  • “There’s a grading-your-own-homework problem,”
  • Meta defines what constitutes harmful content, so it shapes the discussion of how successful it is at dealing with it.”
  • It could reconsider its AI-generated “beauty filters,” which internal research suggested made both the people who used them and those who viewed the images more self-critical
  • the team built a new questionnaire called BEEF, short for “Bad Emotional Experience Feedback.
  • A recurring survey of issues 238,000 users had experienced over the past seven days, the effort identified problems with prevalence from the start: Users were 100 times more likely to tell Instagram they’d witnessed bullying in the last week than Meta’s bullying-prevalence statistics indicated they should.
  • “People feel like they’re having a bad experience or they don’t,” one presentation on BEEF noted. “Their perception isn’t constrained by policy.
  • they seemed particularly common among teens on Instagram.
  • Among users under the age of 16, 26% recalled having a bad experience in the last week due to witnessing hostility against someone based on their race, religion or identity
  • More than a fifth felt worse about themselves after viewing others’ posts, and 13% had experienced unwanted sexual advances in the past seven days.&nbsp;
  • The vast gap between the low prevalence of content deemed problematic in the company’s own statistics and what users told the company they experienced suggested that Meta’s definitions were off, Bejar argued
  • To minimize content that teenagers told researchers made them feel bad about themselves, Instagram could cap how much beauty- and fashion-influencer content users saw.
  • Proving to Meta’s leadership that the company’s prevalence metrics were missing the point was going to require data the company didn’t have. So Bejar and a group of staffers from the Well-Being Team started collecting it
  • And it could build ways for users to report unwanted contacts, the first step to figuring out how to discourage them.
  • One experiment run in response to BEEF data showed that when users were notified that their comment or post had upset people who saw it, they often deleted it of their own accord. “Even if you don’t mandate behaviors,” said Krieger, “you can at least send signals about what behaviors aren’t welcome.”
  • But among the ranks of Meta’s senior middle management, Bejar and Krieger said, BEEF hit a wall. Managers who had made their careers on incrementally improving prevalence statistics weren’t receptive to the suggestion that the approach wasn’t working.&nbsp;
  • After three decades in Silicon Valley, he understood that members of the company’s C-Suite might not appreciate a damning appraisal of the safety risks young users faced from its product—especially one citing the company’s own data.&nbsp;
  • “This was the email that my entire career in tech trained me not to send,” he says. “But a part of me was still hoping they just didn’t know.”
  • “Policy enforcement is analogous to the police,” he wrote in the email Oct. 5, 2021—arguing that it’s essential to respond to crime, but that it’s not what makes a community safe. Meta had an opportunity to do right by its users and take on a problem that Bejar believed was almost certainly industrywide.
  • fter Haugen’s airing of internal research, Meta had cracked down on the distribution of anything that would, if leaked, cause further reputational damage. With executives privately asserting that the company’s research division harbored a fifth column of detractors, Meta was formalizing a raft of new rules for employees’ internal communication.
  • Among the mandates for achieving “Narrative Excellence,” as the company called it, was to keep research data tight and never assert a moral or legal duty to fix a problem.
  • “I had to write about it as a hypothetical,” Bejar said. Rather than acknowledging that Instagram’s survey data showed that teens regularly faced unwanted sexual advances, the memo merely suggested how Instagram might help teens if they faced such a problem.
  • The hope that the team’s work would continue didn’t last. The company stopped conducting the specific survey behind BEEF, then laid off most everyone who’d worked on it as part of what Zuckerberg called Meta’s “year of efficiency.
  • If Meta was to change, Bejar told the Journal, the effort would have to come from the outside. He began consulting with a coalition of state attorneys general who filed suit against the company late last month, alleging that the company had built its products to maximize engagement at the expense of young users’ physical and mental health. Bejar also got in touch with members of Congress about where he believes the company’s user-safety efforts fell short.&nbsp;

One of Us - Lapham's Quarterly - 0 views

  • On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly
  • an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” a document stating that “humans are not unique in possessing the neurological substrates that generate consciousness.” It goes further to conclude that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”
  • Only with the Greeks does there enter the notion of a formal divide between our species, our animal, and every other on earth.

  • there’s that exquisite verse, one of the most beautiful in the Bible, the one that says if God cares deeply about sparrows, don’t you think He cares about you? One is so accustomed to dwelling on the second, human, half of the equation, the comforting part, but when you put your hand over that and consider only the first, it’s a little startling: God cares deeply about the sparrows. Not just that, He cares about them individually. “Are not five sparrows sold for two pennies?” Jesus says. “Yet not one of them is forgotten in God’s sight.”
  • The modern conversation on animal consciousness proceeds, with the rest of the Enlightenment, from the mind of René Descartes, whose take on animals was vividly (and approvingly) paraphrased by the French philosopher Nicolas Malebranche: they “eat without pleasure, cry without pain, grow without knowing it; they desire nothing, fear nothing, know nothing.” Descartes’ term for them was automata
  • In On the Origin of Species, Charles Darwin made the intriguing claim that among the naturalists he knew it was consistently the case that the better a researcher got to know a certain species, the more each individual animal’s actions appeared attributable to “reason and the less to unlearnt instinct.” The more you knew, the more you suspected that they were rational. That marks an important pivot, that thought, insofar as it took place in the mind of someone devoted to extremely close and meticulous study of living animals, a mind that had trained itself not to sentimentalize.
  • The sheer number and variety of experiments carried out in the twentieth century—and with, if anything, a renewed intensity in the twenty-first—exceeds summary. Reasoning, language, neurology, the science of emotions—every chamber where “consciousness” is thought to hide has been probed. Birds and chimps and dolphins have been made to look at themselves in mirrors—to observe whether, on the basis of what they see, they groom or preen (a measure, if somewhat arbitrary, of self-awareness). Dolphins have been found to grieve. Primates have learned symbolic or sign languages and then been interrogated with them. Their answers show thinking but have proved stubbornly open to interpretation on the issue of “consciousness,” with critics warning, as always, about the dangers of anthropomorphism, animal-rights bias, etc.
  • If we put aside the self-awareness standard—and really, how arbitrary and arrogant is that, to take the attribute of consciousness we happen to possess over all creatures and set it atop the hierarchy, proclaiming it the very definition of consciousness (Georg Christoph Lichtenberg wrote something wise in his notebooks, to the effect of: only a man can draw a self-portrait, but only a man wants to)—it becomes possible to say at least the following: the overwhelming tendency of all this scientific work, of its results, has been toward more consciousness. More species having it, and species having more of it than assumed.
  • The animal kingdom is symphonic with mental activity, and of its millions of wavelengths, we’re born able to understand the minutest sliver. The least we can do is have a proper respect for our ignorance.
  • The philosopher Thomas Nagel wrote an essay in 1974 titled, “What Is It Like To Be a Bat?”, in which he put forward perhaps the least overweening, most useful definition of “animal consciousness” ever written, one that channels Spinoza’s phrase about “that nature belonging to him wherein he has his being.” Animal consciousness occurs, Nagel wrote, when “there is something that it is to be that organism—something it is like for the organism.” The strangeness of his syntax carries the genuine texture of the problem. We’ll probably never be able to step far enough outside of our species-reality to say much about what is going on with them, beyond saying how like or unlike us they are. Many things are conscious on the earth, and we are one, and our consciousness feels like this; one of the things it causes us to do is doubt the existence of the consciousness of the other millions of species. But it also allows us to imagine a time when we might stop doing that.
