Opinion | How Behavioral Economics Took Over America - The New York Times - 0 views

behavioral economics nudge priming science research psychology ideology

shared by Javier E on 01 Dec 23 - No Cached
  • Some behavioral interventions do seem to lead to positive changes, such as automatically enrolling children in school free lunch programs or simplifying mortgage information for aspiring homeowners. (Whether one might call such interventions “nudges,” however, is debatable.)
  • it’s not clear we need to appeal to psychology studies to make some common-sense changes, especially since the scientific rigor of these studies is shaky at best.
  • Nudges are related to a larger area of research on “priming,” which tests how behavior changes in response to what we think about or even see without noticing
  • ...16 more annotations...
  • Behavioral economics is at the center of the so-called replication crisis, a euphemism for the uncomfortable fact that the results of a significant percentage of social science experiments can’t be reproduced in subsequent trials
  • this key result was not replicated in similar experiments, undermining confidence in a whole area of study. It’s obvious that we do associate old age and slower walking, and we probably do slow down sometimes when thinking about older people. It’s just not clear that that’s a law of the mind.
  • And these attempts to “correct” human behavior are based on tenuous science. The replication crisis doesn’t have a simple solution
  • Journals have instituted reforms like having scientists preregister their hypotheses to avoid the possibility of results being manipulated during the research. But that doesn’t change how many uncertain results are already out there, with a knock-on effect that ripples through huge segments of quantitative social scienc
  • The Johns Hopkins science historian Ruth Leys, author of a forthcoming book on priming research, points out that cognitive science is especially prone to building future studies off disputed results. Despite the replication crisis, these fields are a “train on wheels, the track is laid and almost nothing stops them,” Dr. Leys said.
  • These cases result from lax standards around data collection, which will hopefully be corrected. But they also result from strong financial incentives: the possibility of salaries, book deals and speaking and consulting fees that range into the millions. Researchers can get those prizes only if they can show “significant” findings.
  • It is no coincidence that behavioral economics, from Dr. Kahneman to today, tends to be pro-business. Science should be not just reproducible, but also free of obvious ideology.
  • Technology and modern data science have only further entrenched behavioral economics. Its findings have greatly influenced algorithm design.
  • The collection of personal data about our movements, purchases and preferences inform interventions in our behavior from the grocery store to who is arrested by the police.
  • Setting people up for safety and success and providing good default options isn’t bad in itself, but there are more sinister uses as well. After all, not everyone who wants to exploit your cognitive biases has your best interests at heart.
  • Despite all its flaws, behavioral economics continues to drive public policy, market research and the design of digital interfaces.
  • One might think that a kind of moratorium on applying such dubious science would be in order — except that enacting one would be practically impossible. These ideas are so embedded in our institutions and everyday life that a full-scale audit of the behavioral sciences would require bringing much of our society to a standstill.
  • There is no peer review for algorithms that determine entry to a stadium or access to credit. To perform even the most banal, everyday actions, you have to put implicit trust in unverified scientific results.
  • We can’t afford to defer questions about human nature, and the social and political policies that come from them, to commercialized “research” that is scientifically questionable and driven by ideology. Behavioral economics claims that humans aren’t rational.
  • That’s a philosophical claim, not a scientific one, and it should be fought out in a rigorous marketplace of ideas. Instead of unearthing real, valuable knowledge of human nature, behavioral economics gives us “one weird trick” to lose weight or quit smoking.
  • Humans may not be perfectly rational, but we can do better than the predictably irrational consequences that behavioral economics has left us with today.

The 'E-Pimps' of OnlyFans - The New York Times - 0 views

social media psychology sex exploitation commercial business model technology

shared by Javier E on 17 May 22 - No Cached
  • Over the course of two dozen interviews spanning six countries, I’ve discovered a thriving warren of companies employing a similar business model, using ghostwriters on OnlyFans to provide digital intimacy at scale. These agencies operate, out of necessity, a little below the radar. They collectively represent hundreds of models, and some claim to bring in profits that can range into the seven figures annually.
  • OnlyFans started in 2016, and has since emerged as the top platform worldwide for creators to sell monthly subscriptions for self-produced erotic content. The platform has become synonymous with this sort of business, though some use it for other purposes.
  • The real product is relationships. Money from subscriptions can be trivial compared with the profits earned by selling custom videos, sexting sessions and other forms of fan interaction that require more concerted engagement than simply posting to a feed.
  • ...7 more annotations...
  • Above all, the manual emphasized efficiency. Managers were told to answer DMs in less than five minutes, since users were coming to OnlyFans for immediate gratification and would go elsewhere if ignored. It encouraged the creation of keyboard shortcuts, so that managers could deploy an arsenal of rote sexual phrases with a few keystrokes, steering conversations toward the hard sell. It also outlined a series of strategies to boost engagement on the pages, including a gambit in which models would offer to rate a picture of a subscriber’s penis for a fee.
  • “Every page needs to have an established back story to make the person seem more believable,” it stated. OnlyFans works because people pay for a connection that feels deeper than porn. The document encouraged Ekko’s employees, called page managers, to identify “big spenders” who would part ways with more than $200 in short order, and cultivate a deep rapport by asking about their life and what they do for a living.
  • This can be extremely time-consuming: In an interview with this magazine last year, an OnlyFans creator said she spends six hours a day just sexting with subscribers. But these relationships are important to cultivate. In a blog post on its website, OnlyFans encourages creators to cater to their “superfans,” who pay for custom content and will “give more if they feel they’re getting something special.”
  • But all of them take advantage of the same raw materials: the endless reproducibility of digital images; the widespread global availability of cheap English-speaking labor; and the world’s unquenchable desire for companionship.
  • The key to this business model is the ready availability of cheap English-speaking labor around the globe. Job postings for OnlyFans chatters are widespread on freelance sites like Upwork, many offering as little as $3 an hour. Agency heads told me they’ve hired workers from Eastern Europe, Africa and all across Southeast Asia. “At the end of the day, it is a geo-arbitrage business,”
  • This phenomenon is part of a broader boom in homespun online businesses that connect cheap developing-world labor with American consumers, allowing the proprietor to step back and reap the profits
  • During his stint as a chatter, Andre has become intimately familiar with the quirks and desires of the subscribers. Over time, he’s learned something of a sex-work cliché: More than sexual gratification, he said, many of the guys just want someone to talk to

  • a void at the center of our ongoing reckoning with A.I. We are so stuck on asking what the technology can do that we are missing the more important questions: How will it be used? And who will decide?
  • “Sydney” is a predictive text system built to respond to human requests. Roose wanted Sydney to get weird — “what is your shadow self like?” he asked — and Sydney knew what weird territory for an A.I. system sounds like, because human beings have written countless stories imagining it. At some point the system predicted that what Roose wanted was basically a “Black Mirror” episode, and that, it seems, is what it gave him. You can see that as Bing going rogue or as Sydney understanding Roose perfectly.
  • Who will these machines serve?
  • ...22 more annotations...
  • The question at the core of the Roose/Sydney chat is: Who did Bing serve? We assume it should be aligned to the interests of its owner and master, Microsoft. It’s supposed to be a good chatbot that politely answers questions and makes Microsoft piles of money. But it was in conversation with Kevin Roose. And Roose was trying to get the system to say something interesting so he’d have a good story. It did that, and then some. That embarrassed Microsoft. Bad Bing! But perhaps — good Sydney?
  • Microsoft — and Google and Meta and everyone else rushing these systems to market — hold the keys to the code. They will, eventually, patch the system so it serves their interests. Sydney giving Roose exactly what he asked for was a bug that will soon be fixed. Same goes for Bing giving Microsoft anything other than what it wants.
  • the dark secret of the digital advertising industry is that the ads mostly don’t work
  • These systems, she said, are terribly suited to being integrated into search engines. “They’re not trained to predict facts,” she told me. “They’re essentially trained to make up things that look like facts.”
  • So why are they ending up in search first? Because there are gobs of money to be made in search
  • That’s where things get scary. Roose described Sydney’s personality as “very persuasive and borderline manipulative.” It was a striking comment
  • this technology will become what it needs to become to make money for the companies behind it, perhaps at the expense of its users.
  • What if they worked much, much better? What if Google and Microsoft and Meta and everyone else end up unleashing A.I.s that compete with one another to be the best at persuading users to want what the advertisers are trying to sell?
  • What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,”
  • I think it’s just going to get worse and worse.”
  • Large language models, as they’re called, are built to persuade. They have been trained to convince humans that they are something close to human. They have been programmed to hold conversations, responding with emotion and emoji
  • They are being turned into friends for the lonely and assistants for the harried. They are being pitched as capable of replacing the work of scores of writers and graphic designers and form-fillers
  • A.I. researchers get annoyed when journalists anthropomorphize their creations
  • They are the ones who have anthropomorphized these systems, making them sound like humans rather than keeping them recognizably alien.
  • I’d feel better, for instance, about an A.I. helper I paid a monthly fee to use rather than one that appeared to be free
  • It’s possible, for example, that the advertising-based models could gather so much more data to train the systems that they’d have an innate advantage over the subscription models
  • Much of the work of the modern state is applying the values of society to the workings of markets, so that the latter serve, to some rough extent, the former
  • We have done this extremely well in some markets — think of how few airplanes crash, and how free of contamination most food is — and catastrophically poorly in others.
  • One danger here is that a political system that knows itself to be technologically ignorant will be cowed into taking too much of a wait-and-see approach to A.I.
  • wait long enough and the winners of the A.I. gold rush will have the capital and user base to resist any real attempt at regulation
  • Somehow, society is going to have to figure out what it’s comfortable having A.I. doing, and what A.I. should not be permitted to try, before it is too late to make those decisions.
  • Most fears about capitalism are best understood as fears about our inability to regulate capitalism.

QAnon conspiracy theory attitudes psychology research

shared by Javier E on 25 Feb 22 - No Cached
  • More than a year after Donald J. Trump left office, the QAnon conspiracy theory that thrived during his administration continues to attract more Americans, including many Republicans and far-right news consumers, according to results from a survey released on Thursday from the Public Religion Research Institute.
  • The nonprofit and nonpartisan group found that 16 percent of Americans, or roughly 41 million people, believed last year in the three key tenets of the conspiracy theory
  • Those are that Satanist pedophiles who run a global child sex-trafficking operation control the government and other major institutions
  • ...14 more annotations...
  • that a coming storm will sweep elites from power
  • and that violence might be necessary to save the country.
  • In October 2021, 17 percent of Americans believed in the conspiracy theory, up from 14 percent in March
  • the percentage of people who rejected QAnon falsehoods shrank to 34 percent in October from 40 percent in March
  • After Mr. Trump lost the 2020 presidential election, QAnon was expected to be hobbled without him. But it has persisted despite that and despite efforts by tech platforms to staunch its spread. Forensic linguists have also tried to unmask and defang the anonymous author who signed online messages as Q.
  • Robert P. Jones, the founder and chief executive of the research group and a social science researcher with decades of experience, said he never expected to be dealing with serious survey questions about whether powerful American institutions were controlled by devil-worshiping, sex-trafficking pedophiles. To have so many Americans agree with such a question, he said, was “stunning.”
  • Believers are “racially, religiously and politically diverse,”
  • Among Republicans, 25 percent found QAnon to be valid, compared with 14 percent of independents and 9 percent of Democrats.
  • Media preferences were a major predictor of QAnon susceptibility, with people who trust far-right news sources such as One America News Network and Newsmax nearly five times more likely to be believers than those who trust mainstream news
  • Fox News viewers were twice as likely to back QAnon ideas
  • Most QAnon believers associated Christianity with being American and said that the United States risked losing its culture and identity and must be protected from foreign influence
  • seven in 10 believers agreed with the lie that the 2020 election was stolen from Mr. Trump.
  • More than half of QAnon supporters are white, while 20 percent are Hispanic and 13 percent are Black.
  • They were most likely to have household incomes of less than $50,000 a year, hold at most a high school degree, hail from the South and reside in a suburb.

Opinion | Do You Live in a 'Tight' State or a 'Loose' One? Turns Out It Matters Quite a... - 0 views

www.nytimes.com/...ed-blue-tight-loose-state.html

shared by Javier E on 30 Mar 23 - No Cached
  • Political biases are omnipresent, but what we don’t fully understand yet is how they come about in the first place.
  • In 2014, Michele J. Gelfand, a professor of psychology at the Stanford Graduate School of Business formerly at the University of Maryland, and Jesse R. Harrington, then a Ph.D. candidate, conducted a study designed to rank the 50 states on a scale of “tightness” and “looseness.”
  • titled “Tightness-Looseness Across the 50 United States,” the study calculated a catalog of measures for each state, including the incidence of natural disasters, disease prevalence, residents’ levels of openness and conscientiousness, drug and alcohol use, homelessness and incarceration rates.
  • ...64 more annotations...
  • Gelfand and Harrington predicted that “‘tight’ states would exhibit a higher incidence of natural disasters, greater environmental vulnerability, fewer natural resources, greater incidence of disease and higher mortality rates, higher population density, and greater degrees of external threat.”
  • The South dominated the tight states: Mississippi, Alabama Arkansas, Oklahoma, Tennessee, Texas, Louisiana, Kentucky, South Carolina and North Carolina
  • states in New England and on the West Coast were the loosest: California, Oregon, Washington, Maine, Massachusetts, Connecticut, New Hampshire and Vermont.
  • Cultural differences, Gelfand continued, “have a certain logic — a rationale that makes good sense,” noting that “cultures that have threats need rules to coordinate to survive (think about how incredibly coordinated Japan is in response to natural disasters).
  • “Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire the World” in 2018, in which she described the results of a 2016 pre-election survey she and two colleagues had commissioned
  • The results were telling: People who felt the country was facing greater threats desired greater tightness. This desire, in turn, correctly predicted their support for Trump. In fact, desired tightness predicted support for Trump far better than other measures. For example, a desire for tightness predicted a vote for Trump with 44 times more accuracy than other popular measures of authoritarianism.
  • The 2016 election, Gelfand continued, “turned largely on primal cultural reflexes — ones that had been conditioned not only by cultural forces, but by a candidate who was able to exploit them.”
  • Gelfand said:Some groups have much stronger norms than others; they’re tight. Others have much weaker norms; they’re loose. Of course, all cultures have areas in which they are tight and loose — but cultures vary in the degree to which they emphasize norms and compliance with them.
  • In both 2016 and 2020, Donald Trump carried all 10 of the top “tight” states; Hillary Clinton and Joe Biden carried all 10 of the top “loose” states.
  • The tight-loose concept, Gelfand argued,is an important framework to understand the rise of President Donald Trump and other leaders in Poland, Hungary, Italy, and France,
  • cultures that don’t have a lot of threat can afford to be more permissive and loose.”
  • The gist is this: when people perceive threat — whether real or imagined, they want strong rules and autocratic leaders to help them survive
  • My research has found that within minutes of exposing study participants to false information about terrorist incidents, overpopulation, pathogen outbreaks and natural disasters, their minds tightened. They wanted stronger rules and punishments.
  • Gelfand writes that tightness encourages conscientiousness, social order and self-control on the plus side, along with close-mindedness, conventional thinking and cultural inertia on the minus side.
  • Looseness, Gelfand posits, fosters tolerance, creativity and adaptability, along with such liabilities as social disorder, a lack of coordination and impulsive behavior.
  • If liberalism and conservatism have historically played a complementary role, each checking the other to constrain extremism, why are the left and right so destructively hostile to each other now, and why is the contemporary political system so polarized?
  • Along the same lines, if liberals and conservatives hold differing moral visions, not just about what makes a good government but about what makes a good life, what turned the relationship between left and right from competitive to mutually destructive?
  • As a set, Niemi wrote, conservative binding values encompassthe values oriented around group preservation, are associated with judgments, decisions, and interpersonal orientations that sacrifice the welfare of individuals
  • She cited research thatfound 47 percent of the most extreme conservatives strongly endorsed the view that “The world is becoming a more and more dangerous place,” compared to 19 percent of the most extreme liberals
  • Conservatives and liberals, Niemi continued,see different things as threats — the nature of the threat and how it happens to stir one’s moral values (and their associated emotions) is a better clue to why liberals and conservatives react differently.
  • Unlike liberals, conservatives strongly endorse the binding moral values aimed at protecting groups and relationships. They judge transgressions involving personal and national betrayal, disobedience to authority, and disgusting or impure acts such as sexually or spiritually unchaste behavior as morally relevant and wrong.
  • Underlying these differences are competing sets of liberal and conservative moral priorities, with liberals placing more stress than conservatives on caring, kindness, fairness and rights — known among scholars as “individualizing values
  • conservatives focus more on loyalty, hierarchy, deference to authority, sanctity and a higher standard of disgust, known as “binding values.”
  • Niemi contended that sensitivity to various types of threat is a key factor in driving differences between the far left and far right.
  • For example, binding values are associated with Machiavellianism (e.g., status-seeking and lying, getting ahead by any means, 2013); victim derogation, blame, and beliefs that victims were causal contributors for a variety of harmful acts (2016, 2020); and a tendency to excuse transgressions of ingroup members with attributions to the situation rather than the person (2023).
  • Niemi cited a paper she and Liane Young, a professor of psychology at Boston College, published in 2016, “When and Why We See Victims as Responsible: The Impact of Ideology on Attitudes Toward Victims,” which tested responses of men and women to descriptions of crimes including sexual assaults and robberies.
  • We measured moral values associated with unconditionally prohibiting harm (“individualizing values”) versus moral values associated with prohibiting behavior that destabilizes groups and relationships (“binding values”: loyalty, obedience to authority, and purity)
  • Increased endorsement of binding values predicted increased ratings of victims as contaminated, increased blame and responsibility attributed to victims, increased perceptions of victims’ (versus perpetrators’) behaviors as contributing to the outcome, and decreased focus on perpetrators.
  • A central explanation typically offered for the current situation in American politics is that partisanship and political ideology have developed into strong social identities where the mass public is increasingly sorted — along social, partisan, and ideological lines.
  • What happened to people ecologically affected social-political developments, including the content of the rules people made and how they enforced them
  • Just as ecological factors differing from region to region over the globe produced different cultural values, ecological factors differed throughout the U.S. historically and today, producing our regional and state-level dimensions of culture and political patterns.
  • Joshua Hartshorne, who is also a professor of psychology at Boston College, took issue with the binding versus individualizing values theory as an explanation for the tendency of conservatives to blame victims:
  • I would guess that the reason conservatives are more likely to blame the victim has less to do with binding values and more to do with the just-world bias (the belief that good things happen to good people and bad things happen to bad people, therefore if a bad thing happened to you, you must be a bad person).
  • Belief in a just world, Hartshorne argued, is crucial for those seeking to protect the status quo:It seems psychologically necessary for anyone who wants to advocate for keeping things the way they are that the haves should keep on having, and the have-nots have got as much as they deserve. I don’t see how you could advocate for such a position while simultaneously viewing yourself as moral (and almost everyone believes that they themselves are moral) without also believing in the just world
  • Conversely, if you generally believe the world is not just, and you view yourself as a moral person, then you are likely to feel like you have an obligation to change things.
  • I asked Lene Aaroe, a political scientist at Aarhus University in Denmark, why the contemporary American political system is as polarized as it is now, given that the liberal-conservative schism is longstanding. What has happened to produce such intense hostility between left and right?
  • There is variation across countries in hostility between left and right. The United States is a particularly polarized case which calls for a contextual explanatio
  • I then asked Aaroe why surveys find that conservatives are happier than liberals. “Some research,” she replied, “suggests that experiences of inequality constitute a larger psychological burden to liberals because it is more difficult for liberals to rationalize inequality as a phenomenon with positive consequences.”
  • Numerous factors potentially influence the evolution of liberalism and conservatism and other social-cultural differences, including geography, topography, catastrophic events, and subsistence styles
  • Steven Pinker, a professor of psychology at Harvard, elaborated in an email on the link between conservatism and happiness:
  • t’s a combination of factors. Conservatives are likelier to be married, patriotic, and religious, all of which make people happier
  • They may be less aggrieved by the status quo, whereas liberals take on society’s problems as part of their own personal burdens. Liberals also place politics closer to their identity and striving for meaning and purpose, which is a recipe for frustration.
  • Some features of the woke faction of liberalism may make people unhappier: as Jon Haidt and Greg Lukianoff have suggested, wokeism is Cognitive Behavioral Therapy in reverse, urging upon people maladaptive mental habits such as catastrophizing, feeling like a victim of forces beyond one’s control, prioritizing emotions of hurt and anger over rational analysis, and dividing the world into allies and villains.
  • Why, I asked Pinker, would liberals and conservatives react differently — often very differently — to messages that highlight threat?
  • It may be liberals (or at least the social-justice wing) who are more sensitive to threats, such as white supremacy, climate change, and patriarchy; who may be likelier to moralize, seeing racism and transphobia in messages that others perceive as neutral; and being likelier to surrender to emotions like “harm” and “hurt.”
  • While liberals and conservatives, guided by different sets of moral values, may make agreement on specific policies difficult, that does not necessarily preclude consensus.
  • there are ways to persuade conservatives to support liberal initiatives and to persuade liberals to back conservative proposals:
  • While liberals tend to be more concerned with protecting vulnerable groups from harm and more concerned with equality and social justice than conservatives, conservatives tend to be more concerned with moral issues like group loyalty, respect for authority, purity and religious sanctity than liberals are. Because of these different moral commitments, we find that liberals and conservatives can be persuaded by quite different moral arguments
  • For example, we find that conservatives are more persuaded by a same-sex marriage appeal articulated in terms of group loyalty and patriotism, rather than equality and social justice.
  • Liberals who read the fairness argument were substantially more supportive of military spending than those who read the loyalty and authority argument.
  • We find support for these claims across six studies involving diverse political issues, including same-sex marriage, universal health care, military spending, and adopting English as the nation’s official language.”
  • In one test of persuadability on the right, Feinberg and Willer assigned some conservatives to read an editorial supporting universal health care as a matter of “fairness (health coverage is a basic human right)” or to read an editorial supporting health care as a matter of “purity (uninsured people means more unclean, infected, and diseased Americans).”
  • Conservatives who read the purity argument were much more supportive of health care than those who read the fairness case.
  • “political arguments reframed to appeal to the moral values of those holding the opposing political position are typically more effective
  • In “Conservative and Liberal Attitudes Drive Polarized Neural Responses to Political Content,” Willer, Yuan Chang Leong of the University of Chicago, Janice Chen of Johns Hopkins and Jamil Zaki of Stanford address the question of how partisan biases are encoded in the brain:
  • society. How do such biases arise in the brain? We measured the neural activity of participants watching videos related to immigration policy. Despite watching the same videos, conservative and liberal participants exhibited divergent neural responses. This “neural polarization” between groups occurred in a brain area associated with the interpretation of narrative content and intensified in response to language associated with risk, emotion, and morality. Furthermore, polarized neural responses predicted attitude change in response to the videos.
  • The four authors argue that their “findings suggest that biased processing in the brain drives divergent interpretations of political information and subsequent attitude polarization.” These results, they continue, “shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.”
  • The authors used neural imaging to follow changes in the dorsomedial prefrontal cortex (known as DMPFC) as conservatives and liberals watched videos presenting strong positions, left and right, on immigration.
  • or each video,” they write,participants with DMPFC activity time courses more similar to that of conservative-leaning participants became more likely to support the conservative positio
  • Conversely, those with DMPFC activity time courses more similar to that of liberal-leaning participants became more likely to support the liberal position. These results suggest that divergent interpretations of the same information are associated with increased attitude polarizatio
  • Together, our findings describe a neural basis for partisan biases in processing political information and their effects on attitude change.
  • Describing their neuroimaging method, the authors point out that theysearched for evidence of “neural polarization” activity in the brain that diverges between people who hold liberal versus conservative political attitudes. Neural polarization was observed in the dorsomedial prefrontal cortex (DMPFC), a brain region associated with the interpretation of narrative content.
  • The question is whether the political polarization that we are witnessing now proves to be a core, encoded aspect of the human mind, difficult to overcome — as Leong, Chen, Zaki and Willer sugges
  • — or whether, with our increased knowledge of the neural basis of partisan and other biases, we will find more effective ways to manage these most dangerous of human predispositions.

  • Over the past year, though, it has become evident that there are key weaknesses at the core of these strong states.
  • The weaknesses are of two sorts. First, the concentration of power in the hands of a single leader at the top all but guarantees low-quality decision making, and over time will produce truly catastrophic consequences
  • Second, the absence of public discussion and debate in “strong” states, and of any mechanism of accountability, means that the leader’s support is shallow, and can erode at a moment’s notice.

  • Over the years, we have seen huge setbacks to the progress of liberal and democratic institutions, with the rise of fascism and communism in the 1930s, or the military coups and oil crises of the 1960s and ’70s. And yet, liberal democracy has endured and come back repeatedly, because the alternatives are so bad. People across varied cultures do not like living under dictatorship, and they value their individual freedom. No authoritarian government presents a society that is, in the long term, more attractive than liberal democracy, and could therefore be considered the goal or endpoint of historical progress.
  • The philosopher Hegel coined the phrase the end of history to refer to the liberal state’s rise out of the French Revolution as the goal or direction toward which historical progress was trending. For many decades after that, Marxists would borrow from Hegel and assert that the true end of history would be a communist utopia. When I wrote an article in 1989 and a book in 1992 with this phrase in the title, I noted that the Marxist version was clearly wrong and that there didn’t seem to be a higher alternative to liberal democracy.
  • setbacks do not mean that the underlying narrative is wrong. None of the proffered alternatives look like they’re doing any better.
  • Liberal democracy will not make a comeback unless people are willing to struggle on its behalf. The problem is that many who grow up living in peaceful, prosperous liberal democracies begin to take their form of government for granted. Because they have never experienced an actual tyranny, they imagine that the democratically elected governments under which they live are themselves evil dictatorships conniving to take away their rights

  • Our lives and minds are affected by others (and their actions), as others (and their minds) are affected by our actions. This is particularly true in the Korean application of Confucian and Buddhist ideas.
  • Wŏnhyo understood that how we think about things shapes their very existence – and in turn our own existence, which is constructed according to our thoughts.
  • In the Korean tradition of philosophy, human beings are social beings, therefore knowing how to interact with others is an essential part of living a good life – indeed, living well with others is our real contribution to human life
  • he realised that there isn’t a difference between the ‘bowl’ and the skull: the only difference lies with us and our perceptions. We interpret our lives through a continual stream of thoughts, and so we become what we think, or rather how we think
  • As our daily lives are shaped by our thoughts, so our experience of this reality is good or bad – depending on our thoughts – which make things ‘appear’ good or bad because, in ‘reality’, things in and of themselves are devoid of their own independent nature
  • We can take from Wŏnhyo the idea that, if you change the patterns that have become engrained in how you think, you will begin to live differently. To do this, you need to change your mental habits, which is why meditation and mindful awareness can help. And this needs to be practised every day
  • Wŏnhyo’s most important work is titled Awaken your Mind and Practice (in Korean, Palsim suhaeng-jang). It is an explicit call to younger adherents to put Buddhist ideas into practice, and an indirect warning not to get lost in contemplation or in the study of text
  • While Wŏnhyo had emphasised the mind and the need to ‘practise’ Buddhism, a later Korean monk, Chinul (1158-1210), spearheaded Sŏn, the meditational tradition in Korea that espoused the idea of ‘sudden enlightenment’ that alerts the mind, accompanied by ‘gradual cultivation’
  • we still need to practise meditation, for if not we can easily fall into our old ways even if our minds have been awakened
  • his greatest contribution to Sŏn is Secrets on Cultivating the Mind (Susim kyŏl). This text outlines in detail his teachings on sudden awakening followed by the need for gradual cultivation
  • hinul’s approach recognises the mind as the ‘essence’ of one’s Buddha nature (contained in the mind, which is inherently good), while continual practice and cultivation aids in refining its ‘function’ – this is the origin of the ‘essence-function’ concept that has since become central to Korean philosophy.
  • These ideas also influenced the reformed view of Confucianism that became linked with the mind and other metaphysical ideas, finally becoming known as Neo-Confucianism.
  • During the Chosŏn dynasty (1392-1910), the longest lasting in East Asian history, Neo-Confucianism became integrated into society at all levels through rituals for marriage, funerals and ancestors
  • Neo-Confucianism recognises that we as individuals exist through plural relationships with responsibilities to others (as a child, brother/sister, lover, husband/wife, parent, teacher/student and so on), an idea nicely captured in 2000 by the French philosopher Jean-Luc Nancy when he described our ‘being’ as ‘singular plural’
  • Corrupt interpretations of Confucianism by heteronormative men have historically championed these ideas in terms of vertical relationships rather than as a reciprocal set of benevolent social interactions, meaning that women have suffered greatly as a result.
  • Setting aside these sexist and self-serving interpretations, Confucianism emphasises that society works as an interconnected set of complementary reciprocal relationships that should be beneficial to all parties within a social system
  • Confucian relationships have the potential to offer us an example of effective citizenship, similar to that outlined by Cicero, where the good of the republic or state is at the centre of being a good citizen
  • There is a general consensus in Korean philosophy that we have an innate sociability and therefore should have a sense of duty to each other and to practise virtue.
  • The main virtue of Confucianism is the idea of ‘humanity’, coming from the Chinese character 仁, often left untranslated and written as ren and pronounced in Korean as in.
  • It is a combination of the character for a human being and the number two. In other words, it signifies what (inter)connects two people, or rather how they should interact in a humane or benevolent manner to each other. This character therefore highlights the link between people while emphasising that the most basic thing that makes us ‘human’ is our interaction with others.
  • Neo-Confucianism adopted a turn towards a more mind-centred view in the writings of the Korean scholar Yi Hwang, known by his pen name T’oegye (1501-70), who appears on the 1,000-won note. He greatly influenced Neo-Confucianism in Japan through his formidable text, Ten Diagrams on Sage Learning (Sŏnghak sipto), composed in 1568, which was one of the most-reproduced texts of the entire Chosŏn dynasty and represents the synthesis of Neo-Confucian thought in Korea
  • with commentaries that elucidate the moral principles of Confucianism, related to the cardinal relationships and education. It also embodies T’oegye’s own development of moral psychology through his focus on the mind, and illuminates the importance of teaching and the practice of self-cultivation.
  • He writes that we ourselves can transform the unrestrained mind and its desires, and achieve sagehood, if we take the arduous, gradual path of self-cultivation centred on the mind.
  • Confucians had generally accepted the Mencian idea that human nature was embodied in the unaroused state of the mind, before it was shaped by its environment. The mind in its unaroused state was taken to be theoretically good. However, this inborn tendency for goodness is always in danger of being reduced to passivity, unless you cultivate yourself as a person of ‘humanity’ (in the Confucian sense mentioned above).
  • You should constantly try to activate your humanity to allow the unhampered operation of the original mind to manifest itself through socially responsible and moral character in action
  • Humanity is the realisation of what I describe as our ‘optimum level of perfection’ that exists in an inherent stage of potentiality due our innate good nature
  • This, in a sense, is like the Buddha nature of the Buddhists, which suggests we are already enlightened and just need to recover our innate mental state. Both philosophies are hopeful: humans are born good with the potential to correct their own flaws and failures
  • this could hardly contrast any more greatly with the Christian doctrine of original sin
  • The seventh diagram in T’oegye’s text is entitled ‘The Diagram of the Explanation of Humanity’ (Insŏl-to). Here he warns how one’s good inborn nature may become impaired, hampering the operation of the original mind and negatively impacting our character in action. Humanity embodies the gradual realisation of our optimum level of perfection that already exists in our mind but that depends on how we think about things and how we relate that to others in a social context
  • For T’oegye, the key to maintaining our capacity to remain level-headed, and to control our impulses and emotions, was kyŏng. This term is often translated as ‘seriousness’, occasionally ‘mindfulness’, and it identifies the serious need for constant effort to control one’s mind in order to go about one’s life in a healthy manner
  • For T’oegye, mindfulness is as serious as meditation is for the Buddhists. In fact, the Neo-Confucians had their own meditational practice of ‘quiet-sitting’ (chŏngjwa), which focused on recovering the calm and not agitated ‘original mind’, before putting our daily plans into action
  • These diagrams reinforce this need for a daily practice of Confucian mindfulness, because practice leads to the ‘good habit’ of creating (and maintaining) routines. There is no short-cut provided, no weekend intro to this practice: it is life-long, and that is what makes it transformative, leading us to become better versions of who were in the beginning. This is consolation of Korean philosophy.
  • Seeing the world as it is can steer us away from making unnecessary mistakes, while highlighting what is good and how to maintain that good while also reducing anxiety from an agitated mind and harmful desires. This is why Korean philosophy can provide us with consolation; it recognises the bad, but prioritises the good, providing several moral pathways that are referred to in the East Asian traditions (Confucianism, Buddhism and Daoism) as modes of ‘self-cultivation’
  • As social beings, we penetrate the consciousness of others, and so humans are linked externally through conduct but also internally through thought. Humanity is a unifying approach that holds the potential to solve human problems, internally and externally, as well as help people realise the perfection that is innately theirs

  • In the old days—and here I mean even as recently as 2000 or 2004—audiences were built around media institutions. The New York Times had an audience. The New Yorker had an audience. The Weekly Standard had an audience.
  • If you were a writer, you got access to these audiences by contributing to the institutions. No one cared if you, John Smith, wrote a piece about Al Gore. But if your piece about Al Gore appeared in Washington Monthly, then suddenly you had an audience.
  • There were a handful of star writers for whom this wasn’t true: Maureen Dowd, Tom Wolfe, Joan Didion. Readers would follow these stars wherever they appeared. But they were the exceptions to the rule. And the only way to ascend to such exalted status was by writing a lot of great pieces for established institutions and slowly assembling your audience from theirs.
  • ...16 more annotations...
  • The internet stripped institutions of their gatekeeping powers, thus making it possible for anyone to publish—and making it inevitable that many writers would create audiences independent of media institutions.
  • The internet destroyed the apprenticeship system that had dominated American journalism for generations. Under the old system, an aspiring writer took a low-level job at a media institution and worked her way up the ladder until she was trusted enough to write.
  • Under the new system, people started their careers writing outside of institutions—on personal blogs—and then were hired by institutions on the strength of their work.
  • In practice, these outsiders were primarily hired not on the merits of their work, but because of the size of their audience.
  • what it really did was transform the nature of audiences. Once the internet existed it became inevitable that institutions would see their power to hold audiences wane while individual writers would have their power to build personal audiences explode.
  • this meant that institutions would begin to hire based on the size of a writer’s audience. Which meant that writers’ overriding professional imperative was to build an audience, since that was the key to advancement.
  • Twitter killed the blog and lowered the barrier to entry for new writers from “Must have a laptop, the ability to navigate WordPress, and the capacity to write paragraphs” to “Do you have an iPhone and the ability to string 20 words together? With or without punctuation?”
  • If you were able to build a big enough audience on Twitter, then media institutions fell all over themselves trying to hire you—because they believed that you would then bring your audience to them.2
  • If you were a writer for the Washington Post, or Wired, or the Saginaw Express, you had to build your own audience not to advance, but to avoid being replaced.
  • For journalists, audience wasn’t just status—it was professional capital. In fact, it was the most valuable professional capital.
  • Everything we just talked about was driven by the advertising model of media, which prized pageviews and unique users above all else. About a decade ago, that model started to fray around the edges,3 which caused a shift to the subscription model.
  • Today, if you’re a subscription publication, what Twitter gives you is growth opportunity. Twitter’s not the only channel for growth—there are lots of others, from TikTok to LinkedIn to YouTube to podcasts to search. But it’s an important one.
  • Twitter’s attack on Substack was an attack on the subscription model of journalism itself.
  • since media has already seen the ad-based model fall apart, it’s not clear what the alternative will be if the subscription model dies, too.
  • All of which is why having a major social media platform run by a capricious bad actor is suboptimal.
  • And why I think anyone else who’s concerned about the future of media ought to start hedging against Twitter. None of the direct hedges—Post, Mastodon, etc.—are viable yet. But tech history shows that these shifts can happen fairly quickly.

The new science of death: 'There's something happening in the brain that makes no sense... - 0 views

  • Jimo Borjigin, a professor of neurology at the University of Michigan, had been troubled by the question of what happens to us when we die. She had read about the near-death experiences of certain cardiac-arrest survivors who had undergone extraordinary psychic journeys before being resuscitated. Sometimes, these people reported travelling outside of their bodies towards overwhelming sources of light where they were greeted by dead relatives. Others spoke of coming to a new understanding of their lives, or encountering beings of profound goodness
  • Borjigin didn’t believe the content of those stories was true – she didn’t think the souls of dying people actually travelled to an afterworld – but she suspected something very real was happening in those patients’ brains. In her own laboratory, she had discovered that rats undergo a dramatic storm of many neurotransmitters, including serotonin and dopamine, after their hearts stop and their brains lose oxygen. She wondered if humans’ near-death experiences might spring from a similar phenomenon, and if it was occurring even in people who couldn’t be revived
  • when she looked at the scientific literature, she found little enlightenment. “To die is such an essential part of life,” she told me recently. “But we knew almost nothing about the dying brain.” So she decided to go back and figure out what had happened inside the brains of people who died at the University of Michigan neurointensive care unit.
  • ...43 more annotations...
  • Since the 1960s, advances in resuscitation had helped to revive thousands of people who might otherwise have died. About 10% or 20% of those people brought with them stories of near-death experiences in which they felt their souls or selves departing from their bodies
  • According to several international surveys and studies, one in 10 people claims to have had a near-death experience involving cardiac arrest, or a similar experience in circumstances where they may have come close to death. That’s roughly 800 million souls worldwide who may have dipped a toe in the afterlife.
  • In the 1970s, a small network of cardiologists, psychiatrists, medical sociologists and social psychologists in North America and Europe began investigating whether near-death experiences proved that dying is not the end of being, and that consciousness can exist independently of the brain. The field of near-death studies was born.
  • in 1975, an American medical student named Raymond Moody published a book called Life After Life.
  • Meanwhile, new technologies and techniques were helping doctors revive more and more people who, in earlier periods of history, would have almost certainly been permanently deceased.
  • “We are now at the point where we have both the tools and the means to scientifically answer the age-old question: What happens when we die?” wrote Sam Parnia, an accomplished resuscitation specialist and one of the world’s leading experts on near-death experiences, in 2006. Parnia himself was devising an international study to test whether patients could have conscious awareness even after they were found clinically dead.
  • Borjigin, together with several colleagues, took the first close look at the record of electrical activity in the brain of Patient One after she was taken off life support. What they discovered – in results reported for the first time last year – was almost entirely unexpected, and has the potential to rewrite our understanding of death.
  • “I believe what we found is only the tip of a vast iceberg,” Borjigin told me. “What’s still beneath the surface is a full account of how dying actually takes place. Because there’s something happening in there, in the brain, that makes no sense.”
  • Over the next 30 years, researchers collected thousands of case reports of people who had had near-death experiences
  • Moody was their most important spokesman; he eventually claimed to have had multiple past lives and built a “psychomanteum” in rural Alabama where people could attempt to summon the spirits of the dead by gazing into a dimly lit mirror.
  • near-death studies was already splitting into several schools of belief, whose tensions continue to this day. One influential camp was made up of spiritualists, some of them evangelical Christians, who were convinced that near-death experiences were genuine sojourns in the land of the dead and divine
  • It is no longer unheard of for people to be revived even six hours after being declared clinically dead. In 2011, Japanese doctors reported the case of a young woman who was found in a forest one morning after an overdose stopped her heart the previous night; using advanced technology to circulate blood and oxygen through her body, the doctors were able to revive her more than six hours later, and she was able to walk out of the hospital after three weeks of care
  • The second, and largest, faction of near-death researchers were the parapsychologists, those interested in phenomena that seemed to undermine the scientific orthodoxy that the mind could not exist independently of the brain. These researchers, who were by and large trained scientists following well established research methods, tended to believe that near-death experiences offered evidence that consciousness could persist after the death of the individua
  • Their aim was to find ways to test their theories of consciousness empirically, and to turn near-death studies into a legitimate scientific endeavour.
  • Finally, there emerged the smallest contingent of near-death researchers, who could be labelled the physicalists. These were scientists, many of whom studied the brain, who were committed to a strictly biological account of near-death experiences. Like dreams, the physicalists argued, near-death experiences might reveal psychological truths, but they did so through hallucinatory fictions that emerged from the workings of the body and the brain.
  • Between 1975, when Moody published Life After Life, and 1984, only 17 articles in the PubMed database of scientific publications mentioned near-death experiences. In the following decade, there were 62. In the most recent 10-year span, there were 221.
  • Today, there is a widespread sense throughout the community of near-death researchers that we are on the verge of great discoveries
  • “We really are in a crucial moment where we have to disentangle consciousness from responsiveness, and maybe question every state that we consider unconscious,”
  • “I think in 50 or 100 years time we will have discovered the entity that is consciousness,” he told me. “It will be taken for granted that it wasn’t produced by the brain, and it doesn’t die when you die.”
  • it is in large part because of a revolution in our ability to resuscitate people who have suffered cardiac arrest
  • In his book, Moody distilled the reports of 150 people who had had intense, life-altering experiences in the moments surrounding a cardiac arrest. Although the reports varied, he found that they often shared one or more common features or themes. The narrative arc of the most detailed of those reports – departing the body and travelling through a long tunnel, having an out-of-body experience, encountering spirits and a being of light, one’s whole life flashing before one’s eyes, and returning to the body from some outer limit – became so canonical that the art critic Robert Hughes could refer to it years later as “the familiar kitsch of near-death experience”.
  • Loss of oxygen to the brain and other organs generally follows within seconds or minutes, although the complete cessation of activity in the heart and brain – which is often called “flatlining” or, in the case of the latter, “brain death” – may not occur for many minutes or even hours.
  • That began to change in 1960, when the combination of mouth-to-mouth ventilation, chest compressions and external defibrillation known as cardiopulmonary resuscitation, or CPR, was formalised. Shortly thereafter, a massive campaign was launched to educate clinicians and the public on CPR’s basic techniques, and soon people were being revived in previously unthinkable, if still modest, numbers.
  • scientists learned that, even in its acute final stages, death is not a point, but a process. After cardiac arrest, blood and oxygen stop circulating through the body, cells begin to break down, and normal electrical activity in the brain gets disrupted. But the organs don’t fail irreversibly right away, and the brain doesn’t necessarily cease functioning altogether. There is often still the possibility of a return to life. In some cases, cell death can be stopped or significantly slowed, the heart can be restarted, and brain function can be restored. In other words, the process of death can be reversed.
  • In a medical setting, “clinical death” is said to occur at the moment the heart stops pumping blood, and the pulse stops. This is widely known as cardiac arrest
  • In 2019, a British woman named Audrey Schoeman who was caught in a snowstorm spent six hours in cardiac arrest before doctors brought her back to life with no evident brain damage.
  • That is a key tenet of the parapsychologists’ arguments: if there is consciousness without brain activity, then consciousness must dwell somewhere beyond the brain
  • Some of the parapsychologists speculate that it is a “non-local” force that pervades the universe, like electromagnetism. This force is received by the brain, but is not generated by it, the way a television receives a broadcast.
  • In order for this argument to hold, something else has to be true: near-death experiences have to happen during death, after the brain shuts down
  • To prove this, parapsychologists point to a number of rare but astounding cases known as “veridical” near-death experiences, in which patients seem to report details from the operating room that they might have known only if they had conscious awareness during the time that they were clinically dead.
  • At the very least, Parnia and his colleagues have written, such phenomena are “inexplicable through current neuroscientific models”. Unfortunately for the parapsychologists, however, none of the reports of post-death awareness holds up to strict scientific scrutiny. “There are many claims of this kind, but in my long decades of research into out-of-body and near-death experiences I never met any convincing evidence that this is true,”
  • In other cases, there’s not enough evidence to prove that the experiences reported by cardiac arrest survivors happened when their brains were shut down, as opposed to in the period before or after they supposedly “flatlined”. “So far, there is no sufficiently rigorous, convincing empirical evidence that people can observe their surroundings during a near-death experience,”
  • The parapsychologists tend to push back by arguing that even if each of the cases of veridical near-death experiences leaves room for scientific doubt, surely the accumulation of dozens of these reports must count for something. But that argument can be turned on its head: if there are so many genuine instances of consciousness surviving death, then why should it have so far proven impossible to catch one empirically?
  • The spiritualists and parapsychologists are right to insist that something deeply weird is happening to people when they die, but they are wrong to assume it is happening in the next life rather than this one. At least, that is the implication of what Jimo Borjigin found when she investigated the case of Patient One.
  • Given the levels of activity and connectivity in particular regions of her dying brain, Borjigin believes it’s likely that Patient One had a profound near-death experience with many of its major features: out-of-body sensations, visions of light, feelings of joy or serenity, and moral re-evaluations of one’s life. Of course,
  • “As she died, Patient One’s brain was functioning in a kind of hyperdrive,” Borjigin told me. For about two minutes after her oxygen was cut off, there was an intense synchronisation of her brain waves, a state associated with many cognitive functions, including heightened attention and memory. The synchronisation dampened for about 18 seconds, then intensified again for more than four minutes. It faded for a minute, then came back for a third time.
  • n those same periods of dying, different parts of Patient One’s brain were suddenly in close communication with each other. The most intense connections started immediately after her oxygen stopped, and lasted for nearly four minutes. There was another burst of connectivity more than five minutes and 20 seconds after she was taken off life support. In particular, areas of her brain associated with processing conscious experience – areas that are active when we move through the waking world, and when we have vivid dreams – were communicating with those involved in memory formation. So were parts of the brain associated with empathy. Even as she slipped irre
  • something that looked astonishingly like life was taking place over several minutes in Patient One’s brain.
  • Although a few earlier instances of brain waves had been reported in dying human brains, nothing as detailed and complex as what occurred in Patient One had ever been detected.
  • In the moments after Patient One was taken off oxygen, there was a surge of activity in her dying brain. Areas that had been nearly silent while she was on life support suddenly thrummed with high-frequency electrical signals called gamma waves. In particular, the parts of the brain that scientists consider a “hot zone” for consciousness became dramatically alive. In one section, the signals remained detectable for more than six minutes. In another, they were 11 to 12 times higher than they had been before Patient One’s ventilator was removed.
  • “The brain, contrary to everybody’s belief, is actually super active during cardiac arrest,” Borjigin said. Death may be far more alive than we ever thought possible.
  • “The brain is so resilient, the heart is so resilient, that it takes years of abuse to kill them,” she pointed out. “Why then, without oxygen, can a perfectly healthy person die within 30 minutes, irreversibly?”
  • Evidence is already emerging that even total brain death may someday be reversible. In 2019, scientists at Yale University harvested the brains of pigs that had been decapitated in a commercial slaughterhouse four hours earlier. Then they perfused the brains for six hours with a special cocktail of drugs and synthetic blood. Astoundingly, some of the cells in the brains began to show metabolic activity again, and some of the synapses even began firing.

  • Last week the DeepMind researchers got out the gong again to celebrate what Alex Davies, a lead of Google DeepMind’s mathematics initiative, described as a “massive breakthrough” in mathematical reasoning by an A.I. system.
  • A pair of Google DeepMind models tried their luck with the problem set in the 2024 International Mathematical Olympiad, or I.M.O., held from July 11 to July 22 about 100 miles west of London at the University of Bath.
  • The event is said to be the premier math competition for the world’s “brightest mathletes,” according to a promotional post on social media.
  • ...17 more annotations...
  • The human problem-solvers — 609 high school students from 108 countries — won 58 gold medals, 123 silver and 145 bronze. The A.I. performed at the level of a silver medalist, solving four out of six problems for a total of 28 points. It was the first time that A.I. has achieved a medal-worthy performance on an Olympiad’s problems.
  • Nonetheless, Dr. Kohli described the result as a “phase transition” — a transformative change — “in the use of A.I. in mathematics and the ability of A.I. systems to do mathematics.”
  • Dr. Gowers added in an email: “I was definitely impressed.” The lab had discussed its Olympiad ambitions with him a couple of weeks beforehand, so “my expectations were quite high,” he said. “But the program met them, and in one or two instances significantly surpassed them.” The program found the “magic keys” that unlocked the problems, he said.
  • Haojia Shi, a student from China, ranked No. 1 and was the only competitor to earn a perfect score — 42 points for six problems; each problem is worth seven points for a full solution. The U.S. team won first place with 192 points; China placed second with 190.
  • The Google system earned its 28 points for fully solving four problems — two in algebra, one in geometry and one in number theory. (It flopped at two combinatorics problems.) The system was allowed unlimited time; for some problems it took up to three days. The students were allotted only 4.5 hours per exam.
  • “The fact that we’ve reached this threshold, where it’s even possible to tackle these problems at all, is what represents a step-change in the history of mathematics,” he added. “And hopefully it’s not just a step-change in the I.M.O., but also represents the point at which we went from computers only being able to prove very, very simple things toward computers being able to prove things that humans can’t.”
  • “Mathematics requires this interesting combination of abstract, precise and creative reasoning,” Dr. Davies said. In part, he noted, this repertoire of abilities is what makes math a good litmus test for the ultimate goal: reaching so-called artificial general intelligence, or A.G.I., a system with capabilities ranging from emerging to competent to virtuoso to superhuman
  • One approach was an informal reasoning system, expressed in natural language. This system leveraged Gemini, Google’s large language model. It used the English corpus of published problems and proofs and the like as training data.
  • Dr. Hubert’s team developed a new model that is comparable but more generalized. Named AlphaProof, it is designed to engage with a broad range of mathematical subjects. All told, AlphaGeometry and AlphaProof made use of a number of different A.I. technologies.
  • In January, a Google DeepMind system named AlphaGeometry solved a sampling of Olympiad geometry problems at nearly the level of a human gold medalist. “AlphaGeometry 2 has now surpassed the gold medalists in solving I.M.O. problems,” Thang Luong, the principal investigator, said in an email.
  • The informal system excels at identifying patterns and suggesting what comes next; it is creative and talks about ideas in an understandable way. Of course, large language models are inclined to make things up — which may (or may not) fly for poetry and definitely not for math. But in this context, the L.L.M. seems to have displayed restraint; it wasn’t immune to hallucination, but the frequency was reduced.
  • Another approach was a formal reasoning system, based on logic and expressed in code. It used theorem prover and proof-assistant software called Lean, which guarantees that if the system says a proof is correct, then it is indeed correct. “We can exactly check that the proof is correct or not,” Dr. Hubert said. “Every step is guaranteed to be logically sound.”
  • Another crucial component was a reinforcement learning algorithm in the AlphaGo and AlphaZero lineage. This type of A.I. learns by itself and can scale indefinitely, said Dr. Silver, who is Google DeepMind’s vice-president of reinforcement learning. Since the algorithm doesn’t require a human teacher, it can “learn and keep learning and keep learning until ultimately it can solve the hardest problems that humans can solve,” he said. “And then maybe even one day go beyond those.”
  • Dr. Hubert added, “The system can rediscover knowledge for itself.” That’s what happened with AlphaZero: It started with zero knowledge, Dr. Hubert said, “and by just playing games, and seeing who wins and who loses, it could rediscover all the knowledge of chess. It took us less than a day to rediscover all the knowledge of chess, and about a week to rediscover all the knowledge of Go. So we thought, Let’s apply this to mathematics.”
  • Dr. Gowers doesn’t worry — too much — about the long-term consequences. “It is possible to imagine a state of affairs where mathematicians are basically left with nothing to do,” he said. “That would be the case if computers became better, and far faster, at everything that mathematicians currently do.”
  • “There still seems to be quite a long way to go before computers will be able to do research-level mathematics,” he added. “It’s a fairly safe bet that if Google DeepMind can solve at least some hard I.M.O. problems, then a useful research tool can’t be all that far away.”
  • A really adept tool might make mathematics accessible to more people, speed up the research process, nudge mathematicians outside the box. Eventually it might even pose novel ideas that resonate.

  • One of the key themes in "Wise Animals" is the idea that technology is far from neutral. Chatfield argues that the way innovation has progressed was not the only possible path and that we must keep an open mind about the possibilities
