Brian Greene: A Physicist Explains 'The Hidden Reality' Of Parallel Universes : NPR - 0 views

  • There are only so many ways matter can arrange itself within that infinite universe. Eventually, matter has to repeat itself and arrange itself in similar ways. So if the universe is infinitely large, it is also home to infinite parallel universes.
  • Greene thinks the key to understanding these multiverses comes from string theory, the area of physics he has studied for the past 25 years. In a nutshell, string theory attempts to reconcile a mathematical conflict between two already accepted ideas in physics: quantum mechanics and the theory of relativity.

Book Review - The Information - By James Gleick - NYTimes.com - 0 views

  • Information, he argues, is more than just the contents of our overflowing libraries and Web servers. It is “the blood and the fuel, the vital principle” of the world. Human consciousness, society, life on earth, the cosmos — it’s bits all the way down.
  • Shannon’s paper, published the same year as the invention of the transistor, instantaneously created the field of information theory, with broad applications in engineering and computer science.
  • information theory wound up reshaping fields from economics to philosophy, and heralded a dramatic rethinking of biology and physics.

  • molecular biologists were soon speaking of information, not to mention codes, libraries, alphabets and transcription, without any sense of metaphor. In Gleick’s words, “Genes themselves are made of bits.” At the same time, physicists exploring what Einstein had called the “spooky” paradoxes of quantum mechanics began to see information as the substance from which everything else in the universe derives. As the physicist John Archibald Wheeler put it in a paper title, “It From Bit.”

Lots of Physicists Are Nervous About the Speed of Light - Technology - The Atlantic Wire - 0 views

  • Until subsequent experiments back up these results, it would be foolish, they say, to throw out a foundational theory of physics.
  • "The correct attitude is to ask oneself what went wrong."
  • "The implications could be huge. Particles that move faster than light are essentially moving backwards in time, which could make the phrase cause and effect obsolete."

Mannequins Give Shape to a Venezuelan Fantasy - NYTimes.com - 0 views

  • “I have lots of clients that come here and say, ‘I want to look like that mannequin,’ ” Ms. Molina said. “I tell them, ‘O.K., then get an operation.’ ”
  • Ms. Corro, the co-owner, explained the changes in the mannequins over just a few years: bigger breasts, bigger buttocks, svelte waists. Until recently, “the mannequins were natural, just like the women were natural,” she said. “The transformation has been both of the woman and of the mannequin.”
  • While Ms. Corro’s mannequins took a quantum leap in body shape several years ago, Ms. Mieles said that the busts and buttocks of her family’s mannequins had grown gradually to keep up with the trends in plastic surgery.

Are scientists blocking their own progress? - The Washington Post - 1 views

  • Max Planck won a Nobel prize for his revolutionary work in quantum mechanics, but it was his interest in the philosophy of science that led to what is now called “Planck’s Principle.” Planck argued that science was an evolving system of thought which changes slowly over time, fueled by the deaths of old ideas. As he wrote in his 1968 autobiography: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
  • Is our understanding of the world based in pure objective reason, or are the theories that underpin it shaped by generational biases? Do our most famous thinkers actually block new ideas from gaining ground?
  • A new paper published by the National Bureau of Economic Research suggests that fame does play a significant role in deciding when and whether new scientific ideas can gain traction. When a prominent scientist dies, the paper’s authors found, the number of articles published by his or her collaborators tends to fall “precipitously” in the years following the death — those supporters tend not to continue advocating for a once-famous scientist’s ideas once the scientist is gone.

  • the number of research articles written by other scientists — including those with opposing ideas — increases by 8 percent on average, implying that the work of these scientists had been stifled before, but that after the death of a ubiquitous figure, the field becomes more open to new ideas. The study also found that these new articles are less likely to cite previous research and are more likely to be cited by others in the field. Death signifies a changing of the guard
  • Our instinct is often to view science as a concrete tower, growing ever upward and built upon the immovable foundations of earlier pioneers.  Sir Isaac Newton famously characterized this as “standing on the shoulders of giants.”
  • Mid-20th century philosopher Thomas Kuhn was among the first to come to this conclusion, in his 1962 book “The Structure of Scientific Revolutions.” He argued that scientific theories appeared in punctuated “paradigm shifts,” in which the underlying assumptions of a field are questioned and eventually overthrown
  • Kuhn’s book was, to some extent, a paradigm shift in its own right. According to his logic, commonly held notions in science were bound to change and become outdated. What we believe today will tomorrow be revised, rewritten — and in the most extreme cases ridiculed.
  • the journal Nature earlier this year said scientific data is prone to bias because researchers design experiments and make observations in ways that support hypotheses
  • equally as important are simple shifts in perspective. It only takes one researcher seeing an accepted scientific model in a new light for a solidified paradigm to enter what Kuhn called a “crisis phase” and beg for alternative explanations
  • The NBER study shows that those who questioned consensus ought to be given the opportunity to make their case, not ignored, silenced or pushed to the back of the line.
  • We’re likely to see these “paradigm shifts” happen at a much faster rate as data and research become easier to share worldwide. For some, this reality might seem chaotic; for the truly curious, it is exhilarating. The result may be a more democratic version of science — one in which the progress of ideas doesn’t have to wait until the funeral of a great mind.

Physicists in Europe Find Tantalizing Hints of a Mysterious New Particle - The New York Times - 1 views

  • seen traces of what could be a new fundamental particle of nature.
  • One possibility, out of a gaggle of wild and not-so-wild ideas springing to life as the day went on, is that the particle — assuming it is real — is a heavier version of the Higgs boson, a particle that explains why other particles have mass. Another is that it is a graviton, the supposed quantum carrier of gravity, whose discovery could imply the existence of extra dimensions of space-time.
  • At the end of a long chain of “ifs” could be a revolution, the first clues to a theory of nature that goes beyond the so-called Standard Model, which has ruled physics for the last quarter-century.

  • noting that the history of particle physics is rife with statistical flukes and anomalies that disappeared when more data was compiled
  • A coincidence is the most probable explanation for the surprising bumps in data from the collider, physicists from the experiments cautioned
  • Physicists could not help wondering if history was about to repeat itself. It was four years ago this week that the same two teams’ detection of matching bumps in Large Hadron Collider data set the clock ticking for the discovery of the Higgs boson six months later.
  • If the particle is real, Dr. Lykken said, physicists should know by this summer, when they will have 10 times as much data to present to scientists from around the world who will convene in Chicago
  • The Higgs boson was the last missing piece of the Standard Model, which explains all we know about subatomic particles and forces. But there are questions this model does not answer, such as what happens at the bottom of a black hole, the identity of the dark matter and dark energy that rule the cosmos, or why the universe is matter and not antimatter.
  • CERN physicists have been running their collider at nearly twice the energy with which they discovered the Higgs, firing twin beams of protons with 6.5 trillion electron volts of energy at each other in search of new particles to help point them to deeper laws.The main news since then has been mainly that there is no news yet, only tantalizing hints, bumps in the data, that might be new particles and signposts of new theories, or statistical demons.
  • Or it could be a more massive particle that has decayed in steps down to a pair of photons. Nobody knows. No model predicted this, which is how some scientists like it.
  • “The more nonstandard the better,” said Joe Lykken, the director of research at the Fermi National Accelerator Laboratory and a member of one of the CERN teams. “It will give people a lot to think about. We get paid to speculate.”
  • When physicists announced in 2012 that they had indeed discovered the Higgs boson, it was not the end of physics. It was not even, to paraphrase Winston Churchill, the beginning of the end.It might, they hoped, be the end of the beginning.
  • Such a discovery would augur a fruitful future for cosmological wanderings and for the CERN collider, which will be running for the next 20 years.

While You Were Sleeping - The New York Times - 0 views

  • look at where we are today thanks to artificial intelligence from digital computers — and the amount of middle-skill and even high-skill work they’re supplanting — and then factor in how all of this could be supercharged in a decade by quantum computing.
  • In December 2016, Amazon announced plans for the Amazon Go automated grocery store, in which a combination of computer vision and deep-learning technologies track items and only charges customers when they remove the items from the store. In February 2017, Bank of America began testing three ‘employee-less’ branch locations that offer full-service banking automatically, with access to a human, when necessary, via video teleconference.”

  • Each time work gets outsourced or tasks get handed off to a machine, “we must reach up and learn a new skill or in some ways expand our capabilities as humans in order to fully realize our collaborative potential,” McGowan said.
  • Therefore, education needs to shift “from education as a content transfer to learning as a continuous process where the focused outcome is the ability to learn and adapt with agency as opposed to the transactional action of acquiring a set skill,
  • “Instructors/teachers move from guiding and accessing that transfer process to providing social and emotional support to the individual as they move into the role of driving their own continuous learning.”

Why Do We Spend So Much Time Teaching Historical Physics? - 0 views

  •  
    One of the two classes I'm teaching this term is our sophomore-level "modern physics" class, which richly deserves its scare quotes. "Modern physics" in an educational context means, essentially, "Physics from 1900-1950." It's a brief introduction to Special Relativity, followed by some introductory quantum physics, and a smattering of applications (solid state, nuclear) as time permits.

How to Defeat Those Who Are Waging War on Science - Scientific American Blog Network - 0 views

  • new language of this war—a subtle, yet potentially damaging form of science skepticism
  • The systematic use of so-called “uncertainty” surrounding well-established scientific ideas has proven to be a reliable method for manipulating public perception and stalling political action.
  • Make no mistake: the War on Science is going to affect you, whether you are a scientist or not. It is going to affect everything—ranging from the safety of the food we eat, the water we drink, the air we breathe, and the kind of planet we live on.
  • ...8 more annotations...
  • The reality is that science touches everything we do, and everyone we love
  • Do we want to be the America that embraces science and the pursuit of knowledge to advance our health, safety, prosperity, and security, making America the leader of the civilized world? Or do want America to mimic failed regimes of the past, where knowledge and science were deliberately suppressed to benefit a few, to funnel more profits into dying industries, and placate the prejudices of a mob
  • Traditionally, scientists have been coached to steer clear of the political fray. But if the past few weeks have taught us anything, it’s that now is the time for a quantum leap of political relevance.
  • You cannot isolate science from politics, or politics from science
  • That is precisely why scientists shouldn’t shy away from engaging in political conversations. Now more than ever, it is necessary to be participating in them
  • At the very least, we all share a deeply-held fascination with our natural world. The search for meaning, the understanding of something bigger than ourselves, is of universal significance.
  • In today’s world, facts alone are not enough to win debates, let alone people’s hearts and minds. Research shows that increasing scientific knowledge can often deepen the divide between people on polarizing issues. “Individuals subconsciously resist factual information that threatens their defining values,” a recent study points out
  • America has a choice to make. A choice between advancing civilization or bringing it down. A choice between knowledge and chaos. Now, everyone must choose which side they are on.

The trouble with atheists: a defence of faith | Books | The Guardian - 1 views

  • My daughter has just turned six. Some time over the next year or so, she will discover that her parents are weird. We're weird because we go to church.
  • This means as she gets older there'll be voices telling her what it means, getting louder and louder until by the time she's a teenager they'll be shouting right in her ear. It means that we believe in a load of bronze-age absurdities. That we fetishise pain and suffering. That we advocate wishy-washy niceness. That we're too stupid to understand the irrationality of our creeds. That we build absurdly complex intellectual structures on the marshmallow foundations of a fantasy. That we're savagely judgmental.
  • that's not the bad news. Those are the objections of people who care enough about religion to object to it. Or to rent a set of recreational objections from Richard Dawkins or Christopher Hitchens. As accusations, they may be a hodge-podge, but at least they assume there's a thing called religion which looms with enough definition and significance to be detested.

  • the really painful message our daughter will receive is that we're embarrassing. For most people who aren't New Atheists, or old atheists, and have no passion invested in the subject, either negative or positive, believers aren't weird because we're wicked. We're weird because we're inexplicable; because, when there's no necessity for it that anyone sensible can see, we've committed ourselves to a set of awkward and absurd attitudes that obtrude, that stick out against the background of modern life, and not in some important or respectworthy or principled way, either.
  • Believers are people who try to insert Jee-zus into conversations at parties; who put themselves down, with writhings of unease, for perfectly normal human behaviour; who are constantly trying to create a solemn hush that invites a fart, a hiccup, a bit of subversion. Believers are people who, on the rare occasions when you have to listen to them, like at a funeral or a wedding, seize the opportunity to pour the liquidised content of a primary-school nativity play into your earhole, apparently not noticing that childhood is over.
  • What goes on inside believers is mysterious. So far as it can be guessed at it appears to be a kind of anxious pretending, a kind of continual, nervous resistance to reality.
  • to me, it's belief that involves the most uncompromising attention to the nature of things of which you are capable. Belief demands that you dispense with illusion after illusion, while contemporary common sense requires continual, fluffy pretending – pretending that might as well be systematic, it's so thoroughly incentivised by our culture.
  • The atheist bus says: "There's probably no God. So stop worrying and enjoy your life."
  • the word that offends against realism here is "enjoy". I'm sorry – enjoy your life?
  • If you based your knowledge of the human species exclusively on adverts, you'd think that the normal condition of humanity was to be a good-looking single person between 20 and 35, with excellent muscle-definition and/or an excellent figure, and a large disposable income. And you'd think the same thing if you got your information exclusively from the atheist bus
  • The implication of the bus slogan is that enjoyment would be your natural state if you weren't being "worried" by us believers and our hellfire preaching. Take away the malignant threat of God-talk, and you would revert to continuous pleasure
  • What's so wrong with this, apart from it being total bollocks? Well, in the first place, that it buys a bill of goods, sight unseen, from modern marketing. Given that human life isn't and can't be made up of enjoyment, it is in effect accepting a picture of human life in which those pieces of living where easy enjoyment is more likely become the only pieces that are visible.
  • But then, like every human being, I am not in the habit of entertaining only those emotions I can prove. I'd be an unrecognisable oddity if I did. Emotions can certainly be misleading: they can fool you into believing stuff that is definitely, demonstrably untrue. Yet emotions are also our indispensable tool for navigating, for feeling our way through, the much larger domain of stuff that isn't susceptible to proof or disproof, that isn't checkable against the physical universe. We dream, hope, wonder, sorrow, rage, grieve, delight, surmise, joke, detest; we form such unprovable conjectures as novels or clarinet concertos; we imagine. And religion is just a part of that, in one sense. It's just one form of imagining, absolutely functional, absolutely human-normal. It would seem perverse, on the face of it, to propose that this one particular manifestation of imagining should be treated as outrageous, should be excised if (which is doubtful) we can manage it.
  • suppose, as the atheist bus goes by, you are povertystricken, or desperate for a job, or a drug addict, or social services have just taken away your child. The bus tells you that there's probably no God so you should stop worrying and enjoy your life, and now the slogan is not just bitterly inappropriate in mood. What it means, if it's true, is that anyone who isn't enjoying themselves is entirely on their own. What the bus says is: there's no help coming.
  • Enjoyment is great. The more enjoyment the better. But enjoyment is one emotion. To say that life is to be enjoyed (just enjoyed) is like saying that mountains should only have summits, or that all colours should be purple, or that all plays should be by Shakespeare. This really is a bizarre category error.
  • A consolation you could believe in would be one that wasn't in danger of popping like a soap bubble on contact with the ordinary truths about us. A consolation you could trust would be one that acknowledged the difficult stuff rather than being in flight from it, and then found you grounds for hope in spite of it, or even because of it
  • The novelist Richard Powers has written that the Clarinet Concerto sounds the way mercy would sound, and that's exactly how I experienced it in 1997. Mercy, though, is one of those words that now requires definition. It does not only mean some tyrant's capacity to suspend a punishment he has himself inflicted. It can mean – and does mean in this case – getting something kind instead of the sensible consequences of an action, or as well as the sensible consequences of an action.
  • from outside, belief looks like a series of ideas about the nature of the universe for which a truth-claim is being made, a set of propositions that you sign up to; and when actual believers don't talk about their belief in this way, it looks like slipperiness, like a maddening evasion of the issue.
  • I am a fairly orthodox Christian. Every Sunday I say and do my best to mean the whole of the Creed, which is a series of propositions. But it is still a mistake to suppose that it is assent to the propositions that makes you a believer. It is the feelings that are primary. I assent to the ideas because I have the feelings; I don't have the feelings because I've assented to the ideas.
  • what I felt listening to Mozart in 1997 is not some wishy-washy metaphor for an idea I believe in, and it's not a front behind which the real business of belief is going on: it's the thing itself. My belief is made of, built up from, sustained by, emotions like that. That's what makes it real.
  • I think that Mozart, two centuries earlier, had succeeded in creating a beautiful and accurate report of an aspect of reality. I think that the reason reality is that way – that it is in some ultimate sense merciful as well as being a set of physical processes all running along on their own without hope of appeal, all the way up from quantum mechanics to the relative velocity of galaxies by way of "blundering, low and horridly cruel" biology (Darwin) – is that the universe is sustained by a continual and infinitely patient act of love. I think that love keeps it in being.
  • That's what I think. But it's all secondary. It all comes limping along behind my emotional assurance that there was mercy, and I felt it. And so the argument about whether the ideas are true or not, which is the argument that people mostly expect to have about religion, is also secondary for me.
  • No, I can't prove it. I don't know that any of it is true. I don't know if there's a God. (And neither do you, and neither does Professor Dawkins, and neither does anybody. It isn't the kind of thing you can know. It isn't a knowable item.)
  • let's be clear about the emotional logic of the bus's message. It amounts to a denial of hope or consolation on any but the most chirpy, squeaky, bubble-gummy reading of the human situation
  • It's got itself established in our culture, relatively recently, that the emotions involved in religious belief must be different from the ones involved in all the other kinds of continuous imagining, hoping, dreaming, and so on, that humans do. These emotions must be alien, freakish, sad, embarrassing, humiliating, immature, pathetic. These emotions must be quite separate from commonsensical us. But they aren't
  • The emotions that sustain religious belief are all, in fact, deeply ordinary and deeply recognisable to anybody who has ever made their way across the common ground of human experience as an adult.
  • It's just that the emotions in question are rarely talked about apart from their rationalisation into ideas. This is what I have tried to do in my new book, Unapologetic.
  • You can easily look up what Christians believe in. You can read any number of defences of Christian ideas. This, however, is a defence of Christian emotions – of their intelligibility, of their grown-up dignity.

Ian Hacking, Eminent Philosopher of Science and Much Else, Dies at 87 - The New York Times - 0 views

  • In an academic career that included more than two decades as a professor in the philosophy department of the University of Toronto, following appointments at Cambridge and Stanford, Professor Hacking’s intellectual scope seemed to know no bounds. Because of his ability to span multiple academic fields, he was often described as a bridge builder.
  • “Ian Hacking was a one-person interdisciplinary department all by himself,” Cheryl Misak, a philosophy professor at the University of Toronto, said in a phone interview. “Anthropologists, sociologists, historians and psychologists, as well as those working on probability theory and physics, took him to have important insights for their disciplines.”
  • Professor Hacking wrote several landmark works on the philosophy and history of probability, including “The Taming of Chance” (1990), which was named one of the best 100 nonfiction books of the 20th century by the Modern Library.
  • ...17 more annotations...
  • “I have long been interested in classifications of people, in how they affect the people classified, and how the effects on the people in turn change the classifications,” he wrote in “Making Up People
  • His work in the philosophy of science was groundbreaking: He departed from the preoccupation with questions that had long concerned philosophers. Arguing that science was just as much about intervention as it was about representation, be helped bring experimentation to center stage.
  • Regarding one such question — whether unseen phenomena like quarks and electrons were real or merely the theoretical constructs of physicists — he argued for reality in the case of phenomena that figured in experiments, citing as an example an experiment at Stanford that involved spraying electrons and positrons into a ball of niobium to detect electric charges. “So far as I am concerned,” he wrote, “if you can spray them, they’re real.”
  • His book “The Emergence of Probability” (1975), which is said to have inspired hundreds of books by other scholars, examined how concepts of statistical probability have evolved over time, shaping the way we understand not just arcane fields like quantum physics but also everyday life.
  • “I was trying to understand what happened a few hundred years ago that made it possible for our world to be dominated by probabilities,” he said in a 2012 interview with the journal Public Culture. “We now live in a universe of chance, and everything we do — health, sports, sex, molecules, the climate — takes place within a discourse of probabilities.”
  • Whatever the subject, whatever the audience, one idea that pervades all his work is that “science is a human enterprise,” Ragnar Fjelland and Roger Strand of the University of Bergen in Norway wrote when Professor Hacking won the Holberg Prize. “It is always created in a historical situation, and to understand why present science is as it is, it is not sufficient to know that it is ‘true,’ or confirmed. We have to know the historical context of its emergence.”
  • Hacking often argued that as the human sciences have evolved, they have created categories of people, and that people have subsequently defined themselves as falling into those categories. Thus does human reality become socially constructed.
  • In 2000, he became the first Anglophone to win a permanent position at the Collège de France, where he held the chair in the philosophy and history of scientific concepts until he retired in 2006.
  • “I call this the ‘looping effect,’” he added. “Sometimes, our sciences create kinds of people that in a certain sense did not exist before.”
  • In “Why Race Still Matters,” a 2005 article in the journal Daedalus, he explored how anthropologists developed racial categories by extrapolating from superficial physical characteristics, with lasting effects — including racial oppression. “Classification and judgment are seldom separable,” he wrote. “Racial classification is evaluation.”
  • Similarly, he once wrote, in the field of mental health the word “normal” “uses a power as old as Aristotle to bridge the fact/value distinction, whispering in your ear that what is normal is also right.”
  • In his influential writings about autism, Professor Hacking charted the evolution of the diagnosis and its profound effects on those diagnosed, which in turn broadened the definition to include a greater number of people.
  • Encouraging children with autism to think of themselves that way “can separate the child from ‘normalcy’ in a way that is not appropriate,” he told Public Culture. “By all means encourage the oddities. By no means criticize the oddities.”
  • His emphasis on historical context also illuminated what he called transient mental illnesses, which appear to be so confined 0cto their time 0c 0cthat they can vanish when times change.
  • “hysterical fugue” was a short-lived epidemic of compulsive wandering that emerged in Europe in the 1880s, largely among middle-class men who had become transfixed by stories of exotic locales and the lure of trave
  • His intellectual tendencies were unmistakable from an early age. “When he was 3 or 4 years old, he would sit and read the dictionary,” Jane Hacking said. “His parents were completely baffled.”
  • He wondered aloud, the interviewer noted, if the whole universe was governed by nonlocality — if “everything in the universe is aware of everything else.”“That’s what you should be writing about,” he said. “Not me. I’m a dilettante. My governing word is ‘curiosity.’”

The Constitution of Knowledge - Persuasion - 0 views

  • But ideas in the marketplace do not talk directly to each other, and for the most part neither do individuals.
  • It is a good metaphor as far as it goes, yet woefully incomplete. It conjures up an image of ideas being traded by individuals in a kind of flea market, or of disembodied ideas clashing and competing in some ethereal realm of their own
  • When Americans think about how we find truth amid a world full of discordant viewpoints, we usually turn to a metaphor, that of the marketplace of ideas
  • ...31 more annotations...
  • Rather, our conversations are mediated through institutions like journals and newspapers and social-media platforms. They rely on a dense network of norms and rules, like truthfulness and fact-checking. They depend on the expertise of professionals, like peer reviewers and editors. The entire system rests on a foundation of values: a shared understanding that there are right and wrong ways to make knowledge.
  • Those values and rules and institutions do for knowledge what the U.S. Constitution does for politics: They create a governing structure, forcing social contestation onto peaceful and productive pathways.
  • I call them, collectively, the Constitution of Knowledge. If we want to defend that system from its many persistent attackers, we need to understand it—and its very special notion of reality.
  • What reality really is
  • The question “What is reality?” may seem either too metaphysical to answer meaningfully or too obvious to need answering
  • The whole problem is that humans have no direct access to an objective world independent of our minds and senses, and subjective certainty is no guarantee of truth. Faced with those problems and others, philosophers and practitioners think of reality as a set of propositions (or claims, or statements) that have been validated in some way, and that have thereby been shown to be at least conditionally true—true, that is, unless debunked
  • Some propositions reflect reality as we perceive it in everyday life (“The sky is blue”). Others, like the equations on a quantum physicist’s blackboard, are incomprehensible to intuition. Many fall somewhere in between.
  • a phrase I used a few sentences ago, “validated in some way,” hides a cheat. In epistemology, the whole question is, validated in what way? If we care about knowledge, freedom, and peace, then we need to stake a strong claim: Anyone can believe anything, but liberal science—open-ended, depersonalized checking by an error-seeking social network—is the only legitimate validator of knowledge, at least in the reality-based community.
  • That is a very bold, very broad, very tough claim, and it goes down very badly with lots of people and communities who feel ignored or oppressed by the Constitution of Knowledge: creationists, Christian Scientists, homeopaths, astrologists, flat-earthers, anti-vaxxers, birthers, 9/11 truthers, postmodern professors, political partisans, QAnon followers, and adherents of any number of other belief systems and religions.
  • But, like the U.S. Constitution’s claim to exclusivity in governing (“unconstitutional” means “illegal,” period), the Constitution of Knowledge’s claim to exclusivity is its sine qua non.
  • Rules for reality
  • The specific proposition does not matter. What does matter is that the only way to validate it is to submit it to the reality-based community. Otherwise, you could win dominance for your proposition by, say, brute force, threatening and jailing and torturing and killing those who see things differently—a standard method down through history
  • Say you believe something (X) to be true, and you believe that its acceptance as true by others is important or at least warranted
  • Or you and your like-minded friends could go off and talk only to each other, in which case you would have founded a cult—which is lawful but socially divisive and epistemically worthless.
  • Or you could engage in a social-media campaign to shame and intimidate those who disagree with you—a very common method these days, but one that stifles debate and throttles knowledge (and harms a lot of people).
  • What the reality-based community does is something else again. Its distinctive qualities derive from two core rules: 
  • what counts is the way the rule directs us to behave: You must assume your own and everyone else’s fallibility and you must hunt for your own and others’ errors, even if you are confident you are right. Otherwise, you are not reality-based.
  • The fallibilist rule: No one gets the final say. You may claim that a statement is established as knowledge only if it can be debunked, in principle, and only insofar as it withstands attempts to debunk it.
  • The empirical rule: No one has personal authority. You may claim that a statement has been established as knowledge only insofar as the method used to check it gives the same result regardless of the identity of the checker, and regardless of the source of the statement
  • Who you are does not count; the rules apply to everybody and persons are interchangeable. If your method is valid only for you or your affinity group or people who believe as you do, then you are not reality-based.
  • Whatever you do to check a proposition must be something that anyone can do, at least in principle, and get the same result. Also, no one proposing a hypothesis gets a free pass simply because of who she is or what group she belongs to.
  • Both rules have very profound social implications. “No final say” insists that to be knowledge, a statement must be checked; and it also says that knowledge is always provisional, standing only as long as it withstands checking.
  • “No personal authority” adds a crucial second step by defining what properly counts as checking. The point, as the great American philosopher Charles Sanders Peirce emphasized more than a century ago, is not that I look or you look but that we look; and then we compare, contest, and justify our views. Critically, then, the empirical rule is a social principle that forces us into the same conversation—a requirement that all of us, however different our viewpoints, agree to discuss what is in principle only one reality.
  • By extension, the empirical rule also dictates what does not count as checking: claims to authority by dint of a personally or tribally privileged perspective.
  • In principle, persons and groups are interchangeable. If I claim access to divine revelation, or if I claim the support of miracles that only believers can witness, or if I claim that my class or race or historically dominant status or historically oppressed status allows me to know and say things that others cannot, then I am breaking the empirical rule by exempting my views from contestability by others.
  • Though seemingly simple, the two rules define a style of social learning that prohibits a lot of the rhetorical moves we see every day.
  • Claiming that a conversation is too dangerous or blasphemous or oppressive or traumatizing to tolerate will almost always break the fallibilist rule.
  • Claims which begin “as a Jew,” or “as a queer,” or for that matter “as minister of information” or “as Pope” or “as head of the Supreme Soviet,” can be valid if they provide useful information about context or credentials; but if they claim to settle an argument by appealing to personal or tribal authority, rather than earned authority, they violate the empirical rule. 
  • “No personal authority” says nothing against trying to understand where people are coming from. If we are debating same-sex marriage, I may mention my experience as a gay person, and my experience may (I hope) be relevant.
  • But statements about personal standing and interest inform the conversation; they do not control it, dominate it, or end it. The rule acknowledges, and to an extent accepts, that people’s social positions and histories matter; but it asks its adherents not to burrow into their social identities, and not to play them as rhetorical trump cards, but to bring them to the larger project of knowledge-building and thereby transcend them.
  • the fallibilist and empirical rules are the common basis of science, journalism, law, and all the other branches of today’s reality-based community. For that reason, both rules also attract hostility, defiance, interference, and open warfare from those who would rather manipulate truth than advance it.
