The brain has bursts of growth and then periods of consolidation, when excess connections are pruned. The most notable bursts are in the first two or three years of life, during puberty, and also a final burst in young adulthood.

t is the most evolutionarily recent brain structure, dealing with more complex cognitive brain activities.

But although it is always tempting to use hard science to explain otherwise perplexing behaviour, neuroimaging research is still in its infancy

There is much about the brain that no one understands yet, and there is rarely a clear relationship between a particular brain region and a discrete function, so any links between brain structure and behaviour remain speculative. Indeed, while researchers often take care to show that the relationship between how a brain looks and how someone behaves is correlative, often this link is misinterpreted as a sign of causation

Scientists also point out that brain science cannot be understood in a vacuum. All behaviour is a function of many influences, including parenting, socioeconomic status, nutrition, culture and so on

You can cast away Picasso because Hannah Gadsby told you he was cruel to women. But can you cast away Guernica?

Art isn’t something mere; it doesn’t exist as the moral bona fides of the person who made it. That person is a supernumerary. Separate yourself from any art—even popular art; even art created simply as entertainment—and you separate yourself from all of it

Artificial intelligence pioneer Ray Kurzweil was among the first to recognize how the link between pattern recognition and human intelligence could be used to build the next generation of artificially intelligent machines.

where human "expertise" has always trumped machine "expertise."

It turns out patterns matter, and they matter a lot.

The more you think about it, the more you can see patterns all around you. Getting to work on time in the morning is the result of recognizing patterns in your daily commute

it's really just a matter of recognizing the right patterns faster than anyone else, and machines just have so much processing power these days it's easy to see them becoming the future doctors and lawyers of the world.

The future of intelligence is in making our patterns better, our heuristics stronger.

One thing is clear – being able to recognize patterns is what gave humans their evolutionary edge over animals.

How we refine, shape and improve our pattern recognition is the key to how much longer we'll have the evolutionary edge over machines.

"What we found at the end of the day was zero correlation with fitness, which I must say was disappointing since I believed, and still believe, there is a tremendous positive impact of exercise on cognitive performance," Grossman says.

"When you go to bed matters," Grossman says. "If you get a certain amount of sleep -- let's say seven hours -- no matter when you get that sleep, as long as it's before certain times, say you go to bed at 10, or at 12, or at 1, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn't everything."

those who got relatively consistent amounts of sleep each night did better than those who had greater variations from one night to the next, even if they ended up with the same average amount.

The overall course grades for students averaging six and a half hours of sleep were down 50 percent from other students who averaged just one hour more sleep. Similarly, those who had just a half-hour more night-to-night variation in their total sleep time had grades that dropped 45 percent below others with less variation. This is huge!"

You might be well-intentioned, rational, and mistaken, simply because so much in our thinking can go wrong. (“RATIONAL, adj.: Devoid of all delusions save those of observation, experience and reflection,”

You might be rational and self-deceptive, because telling yourself that you are rational can itself become a source of bias. It’s possible that you are trying to appear rational only because you want to impress people; or that you are more rational about some things (your job) than others (your kids); or that your rationality gives way to rancor as soon as your ideas are challenged. Perhaps you irrationally insist on answering difficult questions yourself when you’d be better off trusting the expert consensus.

Not just individuals but societies can fall prey to false or compromised rationality. In a 2014 book, “The Revolt of the Public and the Crisis of Authority in the New Millennium,” Martin Gurri, a C.I.A. analyst turned libertarian social thinker, argued that the unmasking of allegedly pseudo-rational institutions had become the central drama of our age: people around the world, having concluded that the bigwigs in our colleges, newsrooms, and legislatures were better at appearing rational than at being so, had embraced a nihilist populism that sees all forms of public rationality as suspect.

modern life would be impossible without those rational systems; we must improve them, not reject them. We have no choice but to wrestle with rationality—an ideal that, the sociologist Max Weber wrote, “contains within itself a world of contradictions.”

Where others might be completely convinced that G.M.O.s are bad, or that Jack is trustworthy, or that the enemy is Eurasia, a Bayesian assigns probabilities to these propositions. She doesn’t build an immovable world view; instead, by continually updating her probabilities, she inches closer to a more useful account of reality. The cooking is never done.

Rationality is one of humanity’s superpowers. How do we keep from misusing it?

Start with the big picture, fixing it firmly in your mind. Be cautious as you integrate new information, and don’t jump to conclusions. Notice when new data points do and do not alter your baseline assumptions (most of the time, they won’t alter them), but keep track of how often those assumptions seem contradicted by what’s new. Beware the power of alarming news, and proceed by putting it in a broader, real-world context.

Bayesian reasoning implies a few “best practices.”

Keep the cooked information over here and the raw information over there; remember that raw ingredients often reduce over heat

We want to live in a more rational society, but not in a falsely rationalized one. We want to be more rational as individuals, but not to overdo it. We need to know when to think and when to stop thinking, when to doubt and when to trust.

But the real power of the Bayesian approach isn’t procedural; it’s that it replaces the facts in our minds with probabilities.

Applied to specific problems—Should you invest in Tesla? How bad is the Delta variant?—the techniques promoted by rationality writers are clarifying and powerful.

the rationality movement is also a social movement; rationalists today form what is sometimes called the “rationality community,” and, as evangelists, they hope to increase its size.

In “Rationality,” “The Scout Mindset,” and other similar books, irrationality is often presented as a form of misbehavior, which might be rectified through education or socialization.

Greg tells me that, in his business, it’s not enough to have rational thoughts. Someone who’s used to pondering questions at leisure might struggle to learn and reason when the clock is ticking; someone who is good at reaching rational conclusions might not be willing to sign on the dotted line when the time comes. Greg’s hedge-fund colleagues describe as “commercial”—a compliment—someone who is not only rational but timely and decisive.

You can know what’s right but still struggle to do it.

Following through on your own conclusions is one challenge. But a rationalist must also be “metarational,” willing to hand over the thinking keys when someone else is better informed or better trained. This, too, is harder than it sounds.

For all this to happen, rationality is necessary, but not sufficient. Thinking straight is just part of the work. 

I found it possible to be metarational with my dad not just because I respected his mind but because I knew that he was a good and cautious person who had my and my mother’s best interests at heart.

between the two of us, we had the right ingredients—mutual trust, mutual concern, and a shared commitment to reason and to act.

Intellectually, we understand that our complex society requires the division of both practical and cognitive labor. We accept that our knowledge maps are limited not just by our smarts but by our time and interests. Still, like Gurri’s populists, rationalists may stage their own contrarian revolts, repeatedly finding that no one’s opinions but their own are defensible. In letting go, as in following through, one’s whole personality gets involved.

in truth, it maps out a series of escalating challenges. In search of facts, we must make do with probabilities. Unable to know it all for ourselves, we must rely on others who care enough to know. We must act while we are still uncertain, and we must act in time—sometimes individually, but often together.

The realities of rationality are humbling. Know things; want things; use what you know to get what you want. It sounds like a simple formula.

The real challenge isn’t being right but knowing how wrong you might be.By Joshua RothmanAugust 16, 2021

Writing about rationality in the early twentieth century, Weber saw himself as coming to grips with a titanic force—an ascendant outlook that was rewriting our values. He talked about rationality in many different ways. We can practice the instrumental rationality of means and ends (how do I get what I want?) and the value rationality of purposes and goals (do I have good reasons for wanting what I want?). We can pursue the rationality of affect (am I cool, calm, and collected?) or develop the rationality of habit (do I live an ordered, or “rationalized,” life?).

Weber worried that it was turning each individual into a “cog in the machine,” and life into an “iron cage.” Today, rationality and the words around it are still shadowed with Weberian pessimism and cursed with double meanings. You’re rationalizing the org chart: are you bringing order to chaos, or justifying the illogical?

For Aristotle, rationality was what separated human beings from animals. For the authors of “The Rationality Quotient,” it’s a mental faculty, parallel to but distinct from intelligence, which involves a person’s ability to juggle many scenarios in her head at once, without letting any one monopolize her attention or bias her against the rest.

In “The Rationality Quotient: Toward a Test of Rational Thinking” (M.I.T.), from 2016, the psychologists Keith E. Stanovich, Richard F. West, and Maggie E. Toplak call rationality “a torturous and tortured term,” in part because philosophers, sociologists, psychologists, and economists have all defined it differently

Galef, who hosts a podcast called “Rationally Speaking” and co-founded the nonprofit Center for Applied Rationality, in Berkeley, barely uses the word “rationality” in her book on the subject. Instead, she describes a “scout mindset,” which can help you “to recognize when you are wrong, to seek out your blind spots, to test your assumptions and change course.” (The “soldier mindset,” by contrast, encourages you to defend your positions at any cost.)

Galef tends to see rationality as a method for acquiring more accurate views.

Pinker, a cognitive and evolutionary psychologist, sees it instrumentally, as “the ability to use knowledge to attain goals.” By this definition, to be a rational person you have to know things, you have to want things, and you have to use what you know to get what you want.

Introspection is key to rationality. A rational person must practice what the neuroscientist Stephen Fleming, in “Know Thyself: The Science of Self-Awareness” (Basic Books), calls “metacognition,” or “the ability to think about our own thinking”—“a fragile, beautiful, and frankly bizarre feature of the human mind.”

A successful student uses metacognition to know when he needs to study more and when he’s studied enough: essentially, parts of his brain are monitoring other parts.

In everyday life, the biggest obstacle to metacognition is what psychologists call the “illusion of fluency.” As we perform increasingly familiar tasks, we monitor our performance less rigorously; this happens when we drive, or fold laundry, and also when we think thoughts we’ve thought many times before

The trick is to break the illusion of fluency, and to encourage an “awareness of ignorance.”

metacognition is a skill. Some people are better at it than others. Galef believes that, by “calibrating” our metacognitive minds, we can improve our performance and so become more rational

There are many calibration methods

nowing about what you know is Rationality 101. The advanced coursework has to do with changes in your knowledge.

Most of us stay informed straightforwardly—by taking in new information. Rationalists do the same, but self-consciously, with an eye to deliberately redrawing their mental maps.

The challenge is that news about distant territories drifts in from many sources; fresh facts and opinions aren’t uniformly significant. In recent decades, rationalists confronting this problem have rallied behind the work of Thomas Bayes

So-called Bayesian reasoning—a particular thinking technique, with its own distinctive jargon—has become de rigueur.

the basic idea is simple. When new information comes in, you don’t want it to replace old information wholesale. Instead, you want it to modify what you already know to an appropriate degree. The degree of modification depends both on your confidence in your preëxisting knowledge and on the value of the new data. Bayesian reasoners begin with what they call the “prior” probability of something being true, and then find out if they need to adjust it.

Bayesian reasoning is an approach to statistics, but you can use it to interpret all sorts of new information.

poptimism has intertwined with a variety of cultural omnivorism that encourages people to embrace the most popular fare from all genres. And this is where the algorithm comes in: it feeds people a steady drip of the most popular things and assures you you’re good for enjoying a diverse array of sameness.

But, and this is important, taste distinctions still matter. Social rank demands fealty to certain ideals of taste, even if artistry isn’t the taste that matters. “Omnivorism, for all of its rejections of ‘taste,’ still presupposes that cultural choice can change society,” Marx writes. “Consumerism can support allies, shame enemies, and deny prestige and financial support to oppressors.”

In the modern cultural landscape, “the hipster” has been replaced by what might be called “der kommisar,” and der kommisar has a few general rules for how to appreciate culture:

1.     Artists should create content that promotes progressive political views and reveals unconscious biases against oppressed groups.2.  Gatekeepers should work to represent minority voices by elevating minority artists.3.     Consumers should only buy artworks and goods with progressive values that are created by upright individuals.4.     Majority groups should never profit on styles or stories that originate within minority groups.5.     Critics should decanonize antiprogressive artists and their works, and question aesthetics associated with high-status distinction.*

“art should avoid being for art’s sake when social equity is at stake.” The quality of artistry matters less than supporting artists who think the right things and say the right things

I don’t think you can really understand much of the last decade or so of cultural writing—or, for that matter, cultural production—if you don’t understand this dynamic and how poptimism, omnivorism, and identity politics have all spun together to change, at the very least, how people talk publicly about the art they consume

"Go ask him what he means by 'I now know what I need to do,'" she instructed Bremmer. "If it's a matter of him picking up an automatic rifle or something, we have to intervene."

As he clarified to Bremmer, love is what he had just realised he had to do. "Love is the most important thing," he told the baffled research assistant. "Nothing matters without

When de Wit recounted this story to me nearly two years after the fact, she still could hardly believe it. "Isn't that amazing?" she said. "It's what everyone says about this damn drug, that it makes people feel love. To think that a drug could change somebody's beliefs and thoughts without any expectations – it's mind-boggling."

Over the past few years, I've been investigating the scientific research and medical potential of MDMA for a book called "I Feel Love: MDMA and the Quest for Connection in a Fractured World". I learnt how this once-vilified drug is now remerging as a therapeutic agent – a role it previously played in the 1970s and 1980s, prior to its criminalisation

He attended the notorious "Unite the Right" rally in Charlottesville and quickly rose up the ranks of his organisation, first becoming the coordinator for Illinois and then the entire Midwest. He travelled to Europe and around the US to meet other white nationalist groups, with the ultimate goal of taking the movement mainstream

some researchers have begun to wonder if it could be an effective tool for pushing people who are already somehow primed to reconsider their ideology toward a new way of seeing things

While MDMA cannot fix societal-level drivers of prejudice and disconnection, on an individual basis it can make a difference. In certain cases, the drug may even be able to help people see through the fog of discrimination and fear that divides so many of us.

in December 2021 I paid Brendan a visit

What I didn't expect was how ordinary the 31-year-old who answered the door would appear to be: blue plaid button-up shirt, neatly cropped hair, and a friendly smile.

Brendan grew up in an affluent Chicago suburb in an Irish Catholic family. He leaned liberal in high school but got sucked into white nationalism at the University of Illinois Urbana-Champaign, where he joined a fraternity mostly composed of conservative Republican men, began reading antisemitic conspiracy books, and fell down a rabbit hole of racist, sexist content online. Brendan was further emboldened by the populist rhetoric of Donald Trump during his presidential campaign. "His speech talking about Mexicans being rapists, the fixation on the border wall and deporting everyone, the Muslim ban – I didn't really get white nationalism until Trump started running for president," Brendan said.

If this comes to pass, MDMA – and other psychedelics-assisted therapy – could transform the field of mental health through widespread clinical use in the US and beyond, for addressing trauma and possibly other conditions as well, including substance use disorders, depression and eating disorders.

A group of anti-fascist activists published identifying information about him and more than 100 other people in Identity Evropa. He was immediately fired from his job and ostracised by his siblings and friends outside white nationalism.

When Brendan saw a Facebook ad in early 2020 for some sort of drug trial at the University of Chicago, he decided to apply just to have something to do and to earn a little money

At the time, Brendan was "still in the denial stage" following his identity becoming public, he said. He was racked with regret – not over his bigoted views, which he still held, but over the missteps that had landed him in this predicament.

About 30 minutes after taking the pill, he started to feel peculiar. "Wait a second – why am I doing this? Why am I thinking this way?" he began to wonder. "Why did I ever think it was okay to jeopardise relationships with just about everyone in my life?"

Just then, Bremmer came to collect Brendan to start the experiment. Brendan slid into an MRI, and Bremmer started tickling his forearm with a brush and asked him to rate how pleasant it felt. "I noticed it was making me happier – the experience of the touch," Brendan recalled. "I started progressively rating it higher and higher." As he relished in the pleasurable feeling, a single, powerful word popped into his mind: connection.

It suddenly seemed so obvious: connections with other people were all that mattered. "This is stuff you can't really put into words, but it was so profound," Brendan said. "I conceived of my relationships with other people not as distinct boundaries with distinct entities, but more as we-are-all-on

I realised I'd been fixated on stuff that doesn't really matter, and is just so messed up, and that I'd been totally missing the point. I hadn't been soaking up the joy that life has to offer."

Brendan hired a diversity, equity, and inclusion consultant to advise him, enrolled in therapy, began meditating, and started working his way through a list of educational books. S still regularly communicates with Brendan and, for his part, thinks that Brendan is serious in his efforts to change

"I think he is trying to better himself and work on himself, and I do think that experience with MDMA had an impact on him. It's been a touchstone for growth, and over time, I think, the reflection on that experience has had a greater impact on him than necessarily the experience itself."

Brendan is still struggling, though, to make the connections with others that he craves. When I visited him, he'd just spent Thanksgiving alone

He also has not completely abandoned his bigoted ideology, and is not sure that will ever be possible. "There are moments when I have racist or antisemitic thoughts, definitely," he said. "But now I can recognise that those kinds of thought patterns are harming me more than anyone else."

it's not without precedent. In the 1980s, for example, an acquaintance of early MDMA-assisted therapy practitioner Requa Greer administered the drug to a pilot who had grown up in a racist home and had inherited those views. The pilot had always accepted his bigoted way of thinking as being a normal, accurate reflection of the way things were. MDMA, however, "gave him a clear vision that unexamined racism was both wrong and mean," Greer says

Encouraging stories of seemingly spontaneous change appear to be exceptions to the norm, however, and from a neurological point of view, this makes sense

Research shows that oxytocin – one of the key hormones that MDMA triggers neurons to release – drives a "tend and defend" response across the animal kingdom. The same oxytocin that causes a mother bear to nurture her newborn, for example, also fuels her rage when she perceives a threat to her cub. In people, oxytocin likewise strengthens caregiving tendencies toward liked members of a person's in-group and strangers perceived to belong to the same group, but it increases hostility toward individuals from disliked groups

In a 2010 study published in Science, for example, men who inhaled oxytocin were three times more likely to donate money to members of their team in an economic game, as well as more likely to harshly punish competing players for not donating enough. (Read more: "The surprising downsides of empathy.")

According to research published this week in Nature by Johns Hopkins University neuroscientist Gül Dölen, MDMA and other psychedelics – including psilocybin, LSD, ketamine and ibogaine – work therapeutically by reopening a critical period in the brain. Critical periods are finite windows of impressionability that typically occur in childhood, when our brains are more malleable and primed to learn new things

Dölen and her colleagues' findings likewise indicate that, without the proper set and setting, MDMA and other psychedelics probably do not reopen critical periods, which means they will not have a spontaneous, revelatory effect for ridding someone of bigoted beliefs.

In the West, plenty of members of right-wing authoritarian political movements, including neo-Nazi groups, also have track records of taking MDMA and other psychedelics

This suggests, researchers write, that psychedelics are nonspecific, "politically pluripotent" amplifiers of whatever is going on in somebody's head, with no particular directional leaning "on the axes of conservatism-liberalism or authoritarianism-egalitarianism."

That said, a growing body of scientific evidence indicates that the human capacity for compassion, kindness, empathy, gratitude, altruism, fairness, trust, and cooperation are core features of our natures

As Emory University primatologist Frans de Waal wrote, "Empathy is the one weapon in the human repertoire that can rid us of the curse of xenophobia."

Ginsberg also envisions using the drug in workshops aimed at eliminating racism, or as a means of bringing people together from opposite sides of shared cultural histories to help heal intergenerational trauma. "I think all psychedelics have a role to play, but I think MDMA has a particularly key role because you're both expanded and present, heart-open and really able to listen in a new way," Ginsberg says. "That's something really powerful."

"If you give MDMA to hard-core haters on each side of an issue, I don't think it'll do a lot of good,"

if you start with open-minded people on both sides, then I think it can work. You can improve communications and build empathy between groups, and help people be more capable of analysing the world from a more balanced perspective rather than from fear-based, anxiety-based distrust."

In 2021, Ginsberg and Doblin were coauthors on a study investigating the possibility of using ayahuasca – a plant-based psychedelic – in group contexts to bridge divides between Palestinians and Israelis, with positive findings

"I kind of have a fantasy that maybe as we get more reacquainted with psychedelics, there could be group-based experiences that build community resiliency and are intentionally oriented toward breaking down barriers between people, having people see things from other perspectives and detribalising our society,

"But that's not going to happen on its own. It would have to be intentional, and – if it happens – it would probably take multiple generations."

Based on his experience with extremism, Brendan agreed with expert takes that no drug, on its own, will spontaneously change the minds of white supremacists or end political conflict in the US

he does think that, with the right framing and mindset, MDMA could be useful for people who are already at least somewhat open to reconsidering their ideologies, just as it was for him. "It helped me see things in a different way that no amount of therapy or antiracist literature ever would have done," he said. "I really think it was a breakthrough experience."

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.

this might explain why it is relative, rather than absolute, inequality that matters so much to people today. In modern Western society, when even relatively poor people have access to transport, refrigeration, entertainment, shoes and plentiful food, you might expect that inequality would be less resented than a century ago—when none of those things might come within the reach of a poor person. What does it matter if there are people who can afford private jets and designer dresses? But clearly that isn't how people think. They resent inequality in luxuries just as much if not more than inequality in necessities. They dislike (and envy) conspicuous consumption, even if it impinges on them not at all. What hurts is not that somebody is rich, but that he is richer.

The iron law of Darwinian evolution is that everything that exists strives with all its power to reproduce, to extend life into the future, and that every feature of every creature can be explained as an adaptation toward this end. For the artist to deny any connection with the enterprise of life, then, is to assert his freedom from this universal imperative; to reclaim negatively the autonomy that evolution seems to deny to human beings. It is only because we can freely choose our own ends that we can decide not to live for life, but for some other value that we posit. The artist’s decision to produce spiritual offspring rather than physical ones is thus allied to the monk’s celibacy and the warrior’s death for his country, as gestures that deny the empire of mere life.

Animals produce beauty on their bodies; humans can also produce it in their artifacts. The natural inference, then, would be that art is a human form of sexual display, a way for males to impress females with spectacularly redundant creations.

For Darwin, the human sense of beauty was not different in kind from the bird’s.

Still, Darwin recognized that the human sense of beauty was mediated by “complex ideas and trains of thought,” which make it impossible to explain in terms as straightforward as a bird’s:

Put more positively, one might say that any given work of art can be discussed critically and historically, but not deduced from the laws of evolution.

with the rise of evolutionary psychology, it was only a matter of time before the attempt was made to explain art in Darwinian terms. After all, if ethics and politics can be explained by game theory and reciprocal altruism, there is no reason why aesthetics should be different: in each case, what appears to be a realm of human autonomy can be reduced to the covert expression of biological imperatives

Still, there is an unmistakable sense in discussions of Darwinian aesthetics that by linking art to fitness, we can secure it against charges of irrelevance or frivolousness—that mattering to reproduction is what makes art, or anything, really matter.

The first popular effort in this direction was the late Denis Dutton’s much-discussed book The Art Instinct, which appeared in 2009.

Dutton’s Darwinism was aesthetically conservative: “Darwinian aesthetics,” he wrote, “can restore the vital place of beauty, skill, and pleasure as high artistic values.” Dutton’s argument has recently been reiterated and refined by a number of new books,

“The universality of art and artistic behaviors, their spontaneous appearance everywhere across the globe ... and the fact that in most cases they can be easily recognized as artistic across cultures suggest that they derive from a natural, innate source: a universal human psychology.”

Again like language, art is universal in the sense that any local expression of it can be “learned” by anyone.

Yet earlier theorists of evolution were reluctant to say that art was an evolutionary adaptation like language, for the simple reason that it does not appear to be evolutionarily adaptive.

Stephen Jay Gould suggested that art was not an evolutionary adaptation but what he called a “spandrel”—that is, a showy but accidental by-product of other adaptations that were truly functiona

the very words “success” and “failure,” despite themselves, bring an emotive and ethical dimension into the discussion, so impossible is it for human beings to inhabit a valueless world. In the nineteenth century, the idea that fitness for survival was a positive good motivated social Darwinism and eugenics. Proponents of these ideas thought that in some way they were serving progress by promoting the flourishing of the human race, when the basic premise of Darwinism is that there is no such thing as progress or regress, only differential rates of reproduction

In particular, Darwin suggests that it is impossible to explain the history or the conventions of any art by the general imperatives of evolution

Boyd begins with the premise that human beings are pattern-seeking animals: both our physical perceptions and our social interactions are determined by our brain’s innate need to find and to

Art, then, can be defined as the calisthenics of pattern-finding. “Just as animal physical play refines performance, flexibility, and efficiency in key behaviors,” Boyd writes, “so human art refines our performance in our key perceptual and cognitive modes, in sight (the visual arts), sound (music), and social cognition (story). These three modes of art, I propose, are adaptations ... they show evidence of special design in humans, design that offers survival and especially reproductive advantages.”

What matters now, Hughes argued, is not whether his fraud claim is true. No, what matters is who believes it.

“You guys took everything that Donald Trump said so literally,” said Lewandowski, who was another ill-advised CNN hire. “The American people didn’t. They understood it. They understood that sometimes — when you have a conversation with people, whether it’s around the dinner table or at a bar — you’re going to say things, and sometimes you don’t have all the facts to back it up.”

“Mr. Trump’s tweet, amongst a certain crowd, a large — a large part of the population, are truth. When he says that millions of people illegally voted, he has some — in his — amongst him and his supporters, and people believe they have facts to back that up. Those that do not like Mr. Trump, they say that those are lies, and there’s no facts to back it up.”

Ousted Trump campaign manager Corey Lewandowski, speaking during an election post-mortem at Harvard University’s Shorenstein Center on Media, Politics and Public Policy, blamed journalists for — yes — believing what his candidate said.

two other Trump surrogates echoed this sentiment.

but Trump is not a guy at a bar; he was the Republican nominee for president of the United States and will pretty soon be the leader of the free world

When CNN’s Jake Tapper asked Trump senior adviser Kellyanne Conway about the same election-fraud claim discussed above — specifically, whether disseminating misinformation was “presidential”

“He’s the president-elect, so that’s presidential behavior,” Conway said, using mind-bending pseudo-logic

Complaining about political correctness is patriotically correct. The patriotically correct must use the non-word “illegals,” or “illegal immigrant” or “illegal alien” to describe foreigners who broke our immigration laws. Dissenters support “open borders” or “shamnesty” for 30 million illegal alien invaders. The punishment is deportation because “we’re a nation of laws” and they didn’t “get in line,” even though no such line actually exists. Just remember that they are never anti-immigration, only anti-illegal immigration, even when they want to cut legal immigration.

Black Lives Matter is racist because it implies that black lives are more important than other lives, but Blue Lives Matter doesn’t imply that cops’ lives are more important than the rest of ours. Banning Islam or Muslim immigration is a necessary security measure, but homosexuals should not be allowed to get married because it infringes on religious liberty. Transgender people could access women’s restrooms for perverted purposes, but Donald Trump walking in on nude underage girls in dressing rooms before a beauty pageant is just “media bias.”

Terrorism is an “existential threat,” even though the chance of being killed in a terrorist attack is about 1 in 3.2 million a year. Saying the words “radical Islam” when describing terrorism is an important incantation necessary to defeat that threat. When Chobani yogurt founder Hamdi Ulukaya decides to employ refugees in his factories, it’s because of his ties to “globalist corporate figures.” Waving a Mexican flag on U.S. soil means you hate America, but waving a Confederate flag just means you’re proud of your heritage.

Insufficient displays of patriotism among the patriotically correct can result in exclusion from public life and ruined careers. It also restricts honest criticism of failed public policies, diverting blame for things like the war in Iraq to those Americans who didn’t support the war effort enough.

Poor white Americans are the victims of economic dislocation and globalization beyond their control, while poor blacks and Hispanics are poor because of their failed cultures. The patriotically correct are triggered when they hear strangers speaking in a language other than English. Does that remind you of the PC duty to publicly shame those who use unacceptable language to describe race, gender or whatever other identity is the victim du jour?

The patriotically correct rightly ridicule PC “safe spaces” but promptly retreat to Breitbart or talk radio, where they can have mutually reinforcing homogeneous temper tantrums while complaining about the lack of intellectual diversity on the left.

There is no such thing as too much national security, but it’s liberals who want to coddle Americans with a “nanny state.”

Those who disagree with the patriotically correct are animated by anti-Americanism, are post-American, or deserve any other of a long list of clunky and vague labels that signal virtue to other members of the patriotic in-group.

Every group has implicit rules against certain opinions, actions and language as well as enforcement mechanisms — and the patriotically correct are no exception. But they are different because they are near-uniformly unaware of how they are hewing to a code of speech and conduct similar to the PC lefties they claim to oppose.

The modern form of political correctness on college campuses and the media is social tyranny with manners, while patriotic correctness is tyranny without the manners, and its adherents do not hesitate to use the law to advance their goals.

Eventually I realised that actions that are individually non-coercive can add up to stable patterns of behaviour that are systematically or structurally coercive, depriving some individuals of their rightful liberty. In fact, rights-violating structures or patterns of behaviour are excellent examples of Hayekian spontaneous orders—of phenomena that are the product of human action, but not of human design. This shift has led me to see racism and sexism themselves as threats to liberty. Racism and sexism have come to matter more to me in that I have come to see them in terms of the political value that matters most to me: liberty. And so I have become much more sympathetic to policies that would limit individual liberty in order to suppress patterns or norms of behaviour that might pose an even greater threat to freedom. So I've become fairly friendly toward federal anti-discrimination law, affirmative action, Title 9, the works. I have found that this sympathy, together with my belief in the theoretical possibility and historical reality of structural coercion, releases me almost entirely from the liberal suspicion that I'm soft on racism (even if I do wish to voucherise Medicare).

this shift in conviction has almost nothing at all to do with a shift in attitude toward any group of people. I say "almost" because it has required that I come to see victims of structural coercion as real victims, really wronged, and thus to see the demand for reform and redress as both legitimate and urgently necessary. And this makes no small difference in one's relationship to those who see it the same way.

First of all, they are not simply for the education of students.  This is an essential function, but the raison d’être of a college is to nourish a world of intellectual culture; that is, a world of ideas, dedicated to what we can know scientifically, understand humanistically, or express artistically.  In our society, this world is mainly populated by members of college faculties: scientists, humanists, social scientists (who straddle the humanities and the sciences properly speaking), and those who study the fine arts. Law, medicine and engineering are included to the extent that they are still understood as “learned professions,” deploying practical skills that are nonetheless deeply rooted in scientific knowledge or humanistic understanding

there are serious concerns about the quality of this experience.  In particular, the university curriculum leaves students disengaged from the material they are supposed to be learning.  They see most of their courses as intrinsically “boring,” of value only if they provide training relevant to future employment or if the teacher has a pleasing (amusing, exciting, “relevant”) way of presenting the material. As a result, students spend only as much time as they need to get what they see as acceptable grades (on average, about 12 to 14 hour a week for all courses combined).  Professors have ceased to expect genuine engagement from students and often give good grades (B or better) to work that is at best minimally adequate.

Our support for higher education makes sense only if we regard this intellectual culture as essential to our society

This has important consequences for how we regard what goes on in college classrooms.  Teachers need to see themselves as, first of all, intellectuals, dedicated to understanding poetry, history, human psychology, physics, biology — or whatever is the focus of their discipline.  But they also need to realize that this dedication expresses not just their idiosyncratic interest in certain questions but a conviction that those questions have general human significance, even apart from immediately practical applications.  This is why a discipline requires not just research but also teaching

Students, in turn, need to recognize that their college education is above all a matter of opening themselves up to new dimensions of knowledge and understanding.  Teaching is not a matter of (as we too often say) “making a subject (poetry, physics, philosophy) interesting” to students but of students coming to see how such subjects are intrinsically interesting.  It is more a matter of students moving beyond their interests than of teachers fitting their subjects to interests that students already have.   Good teaching does not make a course’s subject more interesting; it gives the students more interests — and so makes them more interesting.
