How Google Dominates Us by James Gleick | The New York Review of Books - 1 views

  • Most of the time Google does not actually have the answers. When people say, “I looked it up on Google,” they are committing a solecism. When they try to erase their embarrassing personal histories “on Google,” they are barking up the wrong tree. It is seldom right to say that anything is true “according to Google.” Google is the oracle of redirection. Go there for “hamadryad,” and it points you to Wikipedia. Or the Free Online Dictionary. Or the Official Hamadryad Web Site (it’s a rock band, too, wouldn’t you know). Google defines its mission as “to organize the world’s information,” not to possess it or accumulate it.
  • Then again, a substantial portion of the world’s printed books have now been copied onto the company’s servers, where they share space with millions of hours of video and detailed multilevel imagery of the entire globe, from satellites and from its squadrons of roving street-level cameras. Not to mention the great and growing trove of information Google possesses regarding the interests and behavior of, approximately, everyone.
  • When I say Google “possesses” all this information, that’s not the same as owning it. What it means to own information is very much in flux.

  • The essence of the Web is the linking of individual “pages” on websites, one to another. Every link represents a recommendation—a vote of interest, if not quality. So the algorithm assigns every page a rank, depending on how many other pages link to it. Furthermore, all links are not valued equally. A recommendation is worth more when it comes from a page that has a high rank itself. The math isn’t trivial—PageRank is a probability distribution, and the calculation is recursive, each page’s rank depending on the ranks of pages that depend…and so on. Page and Brin patented PageRank and published the details even before starting the company they called Google.
  • As they saw it from the first, their mission encompassed not just the Internet but all the world’s books and images, too.

Raymond Tallis Takes Out the 'Neurotrash' - The Chronicle Review - The Chronicle of Hig... - 0 views

  • Tallis informs 60 people gathered in a Kent lecture hall that his talk will demolish two "pillars of unwisdom." The first, "neuromania," is the notion that to understand people you must peer into the "intracranial darkness" of their skulls with brain-scanning technology. The second, "Darwinitis," is the idea that Charles Darwin's evolutionary theory can explain not just the origin of the human species—a claim Tallis enthusiastically accepts—but also the nature of human behavior and institutions.
  • Aping Mankind argues that neuroscientific approaches to things like love, wisdom, and beauty are flawed because you can't reduce the mind to brain activity alone.
  • Stephen Cave, a Berlin-based philosopher and writer who has called Aping Mankind "an important work," points out that most philosophers and scientists do in fact believe "that mind is just the product of certain brain activity, even if we do not currently know quite how." Tallis "does both the reader and these thinkers an injustice" by declaring that view "obviously" wrong,
  • ...5 more annotations...
  • Geraint Rees, director of University College London's Institute of Cognitive Neuroscience, complains that reading Tallis is "a bit like trying to nail jelly to the wall." He "rubbishes every current theory of the relationship between mind and brain, whether philosophical or neuroscientific," while offering "little or no alternative,"
  • cultural memes. The Darwinesque concept originates in Dawkins's 1976 book, The Selfish Gene. Memes are analogous to genes, Dennett has said, "replicating units of culture" that spread from mind to mind like a virus. Religion, chess, songs, clothing, tolerance for free speech—all have been described as memes. Tallis considers it absurd to talk of a noun-phrase like "tolerance for free speech" as a discrete entity. But Dennett argues that Tallis's objections are based on "a simplistic idea of what one might mean by a unit." Memes aren't units? Well, in that spirit, says Dennett, organisms aren't units of biology, nor are species—they're too complex, with too much variation. "He's got to allow theory to talk about entities which are not simple building blocks," Dennett says.
  • How is it that he perceives the glass of water on the table? How is it that he feels a sense of self over time? How is it that he can remember a patient he saw in 1973, and then cast his mind forward to his impending visit to the zoo? There are serious problems with trying to reduce such things to impulses in the brain, he argues. We can explain "how the light gets in," he says, but not "how the gaze looks out." And isn't it astonishing, he adds, that much neural activity seems to have no link to consciousness? Instead, it's associated with things like controlling automatic movements and regulating blood pressure. Sure, we need the brain for consciousness: "Chop my head off, and my IQ descends." But it's not the whole story. There is more to perceptions, memories, and beliefs than neural impulses can explain. The human sphere encompasses a "community of minds," Tallis has written, "woven out of a trillion cognitive handshakes of shared attention, within which our freedom operates and our narrated lives are led." Those views on perception and memory anchor his attack on "neurobollocks." Because if you can't get the basics right, he says, then it's premature to look to neuroscience for clues to complex things like love.
  • Yes, many unanswered questions persist. But these are early days, and neuroscience remains immature, says Churchland, a professor emerita of philosophy at University of California at San Diego and author of the subfield-spawning 1986 book Neurophilosophy. In the 19th century, she points out, people thought we'd never understand light. "Well, by gosh," she says, "by the time the 20th century rolls around, it turns out that light is electromagnetic radiation. ... So the fact that at a certain point in time something seems like a smooth-walled mystery that we can't get a grip on, doesn't tell us anything about whether some real smart graduate student is going to sort it out in the next 10 years or not."
  • Dennett claims he's got much of it sorted out already. He wrote a landmark book on the topic in 1991, Consciousness Explained. (The title "should have landed him in court, charged with breach of the Trade Descriptions Act," writes Tallis.) Dennett uses the vocabulary of computer science to explain how consciousness emerges from the huge volume of things happening in the brain all at once. We're not aware of everything, he tells me, only a "limited window." He describes that stream of consciousness as "the activities of a virtual machine which is running on the parallel hardware of the brain." "You—the fruits of all your experience, not just your genetic background, but everything you've learned and done and all your memories—what ties those all together? What makes a self?" Dennett asks. "The answer is, and has to be, the self is like a software program that organizes the activities of the brain."

How Not to Explain Success - The New York Times - 0 views

  • DO you remember the controversy two years ago, when the Yale law professors Amy Chua (author of “Battle Hymn of the Tiger Mother”) and Jed Rubenfeld published “The Triple Package: How Three Unlikely Traits Explain the Rise and Fall of Cultural Groups in America”?We sure do. As psychologists, we found the book intriguing, because its topic — why some people succeed and others don’t — has long been a basic research question in social science, and its authors were advancing a novel argument. They contended that certain ethnic and religious minority groups (among them, Cubans, Jews and Indians) had achieved disproportionate success in America because their individual members possessed a combination of three specific traits: a belief that their group was inherently superior to others; a sense of personal insecurity; and a high degree of impulse control.
  • it offered no rigorous quantitative evidence to support its theory. This, of course, didn’t stop people from attacking or defending the book. But it meant that the debate consisted largely of arguments based on circumstantial evidence.
  • we took the time to empirically test the triple package hypothesis directly. Our results have just been published in the journal Personality and Individual Differences. We found scant evidence for Professors Chua and Rubenfeld’s theory.
  • ...7 more annotations...
  • We conducted two online surveys of a total of 1,258 adults in the United States. Each participant completed a variety of standard questionnaires to measure his or her impulsiveness, ethnocentrism and personal insecurity. (Professors Chua and Rubenfeld describe insecurity as “a goading anxiety about oneself and one’s place in society.” Since this concept was the most complex and counterintuitive element of their theory, we measured it several different ways, each of which captured a slightly different aspect.)Next, the participants completed a test of their cognitive abilities. Then they reported their income, occupation, education and other achievements, such as receiving artistic, athletic or leadership awards, all of which we combined to give each person a single score for overall success. Finally, our participants indicated their age, sex and parents’ levels of education.
  • First, the more successful participants had higher cognitive ability, more educated parents and better impulse control.
  • This finding is exactly what you would expect from accepted social science. Long before “The Triple Package,” researchers determined that the personality trait of conscientiousness, which encompasses the triple package’s impulse control component, was an important predictor of success — but that a person’s intelligence and socioeconomic background were equally or even more important.
  • Our second finding was that the more successful participants did not possess greater feelings of ethnocentrism or personal insecurity. In fact, for insecurity, the opposite was true: Emotional stability was related to greater success.
  • Finally, we found no special “synergy” among the triple package traits. According to Professors Chua and Rubenfeld, the three traits have to work together to create success — a sense of group superiority creates drive only in people who also view themselves as not good enough, for example, and drive is useless without impulse control. But in our data, people scoring in the top half on all three traits were no more successful than everyone else.
  • To be clear, we have no objection to Professors Chua and Rubenfeld’s devising a novel social-psychological theory of success. During the peer-review process before publication, our paper was criticized on the grounds that a theory created by law professors could not have contributed to empirical social science, and that ideas published in a popular book did not merit evaluation in an academic journal.We disagree. Outsiders can make creative and even revolutionary contributions to a discipline, as the psychologists Amos Tversky and Daniel Kahneman did for economics. And professors do not further the advancement of knowledge by remaining aloof from debates where they can apply their expertise. Researchers should engage the public, dispel popular myths and even affirm “common sense” when the evidence warrants.
  • it did not stand up to direct empirical tests. Our conclusion regarding “The Triple Package” is expressed by the saying, “What is new is not correct, and what is correct is not new.”

What Does Quantum Physics Actually Tell Us About the World? - The New York Times - 2 views

  • The physics of atoms and their ever-smaller constituents and cousins is, as Adam Becker reminds us more than once in his new book, “What Is Real?,” “the most successful theory in all of science.” Its predictions are stunningly accurate, and its power to grasp the unseen ultramicroscopic world has brought us modern marvels.
  • But there is a problem: Quantum theory is, in a profound way, weird. It defies our common-sense intuition about what things are and what they can do.
  • Indeed, Heisenberg said that quantum particles “are not as real; they form a world of potentialities or possibilities rather than one of things or facts.”
  • ...19 more annotations...
  • Before he died, Richard Feynman, who understood quantum theory as well as anyone, said, “I still get nervous with it...I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.” The problem is not with using the theory — making calculations, applying it to engineering tasks — but in understanding what it means. What does it tell us about the world?
  • From one point of view, quantum physics is just a set of formalisms, a useful tool kit. Want to make better lasers or transistors or television sets? The Schrödinger equation is your friend. The trouble starts only when you step back and ask whether the entities implied by the equation can really exist. Then you encounter problems that can be described in several familiar ways:
  • Wave-particle duality. Everything there is — all matter and energy, all known forces — behaves sometimes like waves, smooth and continuous, and sometimes like particles, rat-a-tat-tat. Electricity flows through wires, like a fluid, or flies through a vacuum as a volley of individual electrons. Can it be both things at once?
  • The uncertainty principle. Werner Heisenberg famously discovered that when you measure the position (let’s say) of an electron as precisely as you can, you find yourself more and more in the dark about its momentum. And vice versa. You can pin down one or the other but not both.
  • The measurement problem. Most of quantum mechanics deals with probabilities rather than certainties. A particle has a probability of appearing in a certain place. An unstable atom has a probability of decaying at a certain instant. But when a physicist goes into the laboratory and performs an experiment, there is a definite outcome. The act of measurement — observation, by someone or something — becomes an inextricable part of the theory
  • The strange implication is that the reality of the quantum world remains amorphous or indefinite until scientists start measuring
  • Other interpretations rely on “hidden variables” to account for quantities presumed to exist behind the curtain.
  • This is disturbing to philosophers as well as physicists. It led Einstein to say in 1952, “The theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.”
  • “Figuring out what quantum physics is saying about the world has been hard,” Becker says, and this understatement motivates his book, a thorough, illuminating exploration of the most consequential controversy raging in modern science.
  • In a way, the Copenhagen is an anti-interpretation. “It is wrong to think that the task of physics is to find out how nature is,” Bohr said. “Physics concerns what we can say about nature.”
  • Nothing is definite in Bohr’s quantum world until someone observes it. Physics can help us order experience but should not be expected to provide a complete picture of reality. The popular four-word summary of the Copenhagen interpretation is: “Shut up and calculate!”
  • Becker sides with the worriers. He leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories
  • He makes a convincing case that it’s wrong to imagine the Copenhagen interpretation as a single official or even coherent statement. It is, he suggests, a “strange assemblage of claims.
  • An American physicist, David Bohm, devised a radical alternative at midcentury, visualizing “pilot waves” that guide every particle, an attempt to eliminate the wave-particle duality.
  • Competing approaches to quantum foundations are called “interpretations,” and nowadays there are many. The first and still possibly foremost of these is the so-called Copenhagen interpretation.
  • Perhaps the most popular lately — certainly the most talked about — is the “many-worlds interpretation”: Every quantum event is a fork in the road, and one way to escape the difficulties is to imagine, mathematically speaking, that each fork creates a new universe
  • if you think the many-worlds idea is easily dismissed, plenty of physicists will beg to differ. They will tell you that it could explain, for example, why quantum computers (which admittedly don’t yet quite exist) could be so powerful: They would delegate the work to their alter egos in other universes.
  • When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human.
  • If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation...exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

Want the Good Life? This Philosopher Suggests Learning From Cats. - The New York Times - 0 views

  • On the face of it, “Feline Philosophy” would seem like a departure for Gray — a playful exploration of what cats might have to teach humans in our never-ending quest to understand ourselves. But the book, in true Gray fashion, suggests that this very quest may itself be doomed. “Consciousness,” he writes, “has been overrated.”
  • We get worried, anxious and miserable. Our vaunted capacity for abstract thought often gets us (or others) into trouble. We may be the only species to pursue scientific inquiry, but we’re also the only species that has consciously perpetrated genocides. Cats, unlike humans, don’t trick themselves into believing they are saviors, wreaking havoc in the process.

  • A recent profile of Gray in The Guardian remarked on his unusual political journey — from a working-class upbringing in Northern England; to support for Thatcherism in the 1980s; to a dalliance with New Labour in the ’90s before he abandoned that, too, after it became yet another “universal project” he considered in thrall to a distorted view of human possibility
  • He was in favor of Brexit, and has written sympathetically of those who voted Leave, deeming the European Union another grand scheme shot through with arrogant idealism. In its place, Gray wants to see … well, something that’s never fully defined.

The Power of Positive Thinking: Too Much and Never Enough - The Bulwark - 1 views

  • Peale was exceptional for cutting the flock some spiritual slack, encouraging them to look for the sunny side and conquer their inferiority complexes. In his world, you can have the economic gains minus the guilt, which seems perfectly suited to the American sensibility.
  • The book sold millions of copies and was eventually translated into more than 40 languages, and Peale, from his pulpit at Marble Collegiate Church in Manhattan, became central to the spiritual life of the family of Fred Trump Sr., his wife, Mary, and the four Trump children, including the future president.
  • it was also well suited to justifying and exacerbating the pathologies of the Trump family and businesses
  • ...12 more annotations...
  • Mary Trump (the president’s niece who also happens to have a Ph.D. in psychology) paints a portrait of Fred Trump Sr. as a sociopath, utterly uninterested in entering into the moral, emotional, and psychological world of his family or its members. In keeping with Peale’s teaching, he would no more hear about his wife’s or children’s problems than he would accept a failed business deal
  • Fred would just say, “Everything’s great, right Toots?” refusing to acknowledge, much less accommodate, her illness. 
  • Fred Jr. was then further abused, repeatedly denied authority, second-guessed at every turn, and blamed for every problem, setback, and failure in a perverse tag-team between Fred Sr. and Donald. The abuse fed his alcoholism, which, in the family’s Peale-informed understanding, was not a disease requiring treatment but the result of Fred Jr.’s negative thinking
  • Peale wanted people to be hopeful, kind, and optimistic, and to become “people persons.” The Trump family heard the positive thinking, personal empowerment parts, which integrated easily with its win-at-all-cost ideology, but they, or at least Donald, missed the bits about seeking counsel from others and living a life of dependence upon God.
  • Fred Jr.’s deepening alcoholism only elicited increasing abuse from his father and brother seemingly under the theory that if they were hard enough on him he would turn around. Even in his final crisis, afflicted by fatal, alcohol-induced cardiac problems, no member of the family went with him to the hospital (Donald Trump went to a movie instead). Dying, it appears, is the result of late-stage negative thought.
  • The consistent element in each of these has been to deny negative realities and keep moving. The casinos, the airline, the football league, Trump Vodka, Trump Steaks, Trump University . . . all bear the same markings of hyper optimism and overpromise/underdeliver salesmanship
  • Trump’s just doing what he’s always done: conquering the challenge by blinding himself to it, just the way Reverend Peale taught him and his father insisted upon. 
  • My AEI colleague, Brad Wilcox, documented that men who identified as “evangelical” but infrequently attend church were more likely to engage in domestic violence than evangelicals who regularly attended church, mainline Protestants and those who never attend church. Wilcox believes this results from a kind of doctrinal cherry-picking—big on authority, sovereignty, and power but closed to other-directed teachings like altruism and self-sacrifice. Weak attachment to religious faith tends to put some of the worst behaviors on steroids.  
  • These are the problem-solving strategies that Donald Trump brought to his marriages, six corporate bankruptcies, presidential campaign, and now, what increasingly appears to be a failed presidency.
  • “prosperity gospel” (a belief popularized by televangelists that God intends Christians to be healthy and wealthy)
  • The purpose of these psychological and spiritual practices is to free individuals from self-doubt and feelings of inferiority and help them to become the people God truly intends them to be: happy, wealthy, popular, and professionally successful.
  • Now we have Trump COVID-19 and it’s following the same pattern. The virus is “very well under control” and “going to fade away.”

Screen time: Mental health menace or scapegoat? - CNN - 0 views

  • (CNN)"Have smartphones destroyed a generation?" Jean Twenge, a professor of psychology at San Diego State University, asked in an adapted excerpt of her controversial book, "iGen."In the book, she argues that those born after 1995 are on the "brink of a mental-health crisis" -- and she believes it can be linked to growing up with their noses pressed against a screen.
  • For those who responded 10 to 19 hours per week, that number was about 18%. For those who spent 40 or more hours a week using social media, that number approached 24%.
  • By the twelfth grade, however, the negative correlations between screen time and teen psychology had somewhat dissipated. In addition, less is not always more: Teens with zero hours of screen time had higher rates of unhappiness than their peers who logged in a few hours a week.
  • ...4 more annotations...
  • Twenge recognizes that her study shows only a correlation between screen use and "psychological well-being," which is measured using survey questions about self-esteem, life satisfaction and happiness. The surveys can't say whether screen time directly changes teens' mental health, the research states.
  • "I spent my career in technology. I wasn't prepared for its effect on my kids," philanthropist Melinda Gates, whose three children were also born after 1995, wrote August in the Washington Post. "Phones and apps aren't good or bad by themselves, but for adolescents who don't yet have the emotional tools to navigate life's complications and confusions, they can exacerbate the difficulties of growing up."
  • At the same time, she said, kids are learning on their devices and connecting in novel ways. "Marginalized groups such as gay and lesbian students (are) finding support they never had before through social networks," said Gates.
  • Other studies have explored the connection between social media and isolation and how "likes" activate the brain's reward center. Some analyses have found that moderate use of these technologies is "not intrinsically harmful" and can even improve social skills and develop resilience.

Book Review - Examined Lives - By James Miller - NYTimes.com - 0 views

  • Miller has now had the superb idea of taking Diogenes Laertius as a model, while simultaneously using this model to test whether such an approach can still offer us anything of value. He covers 12 philosophers: Socrates, Plato, Diogenes the Cynic (not to be confused with Laertius), Aristotle, Seneca, Augustine, Montaigne, Descartes, Rousseau, Kant, Emerson and Nietzsche. In each case, he explores the life selectively, looking for “crux” points and investigating how ideas of the philosophical life have changed.
  • Miller concludes that his 12 philosophical lives offer a moral that is “neither simple nor uniformly edifying.” It amounts mainly to the idea that philosophy can offer little or no consolation, and that the examined life is, if anything, “harder and less potentially rewarding” for us than it was for Socrates.

Book Review: 'A New History of Life' by Peter Ward and Joe Kirschvink - WSJ - 0 views

  • I imagine that physicists are similarly deluged with revelations about how to build a perpetual-motion machine or about the hitherto secret truth behind relativity. And so I didn’t view the arrival of “A New History of Life” with great enthusiasm.
  • subtitle breathlessly promises “radical new discoveries about the origins and evolution of life on earth,” while the jacket copy avers that “our current paradigm for understanding the history of life on Earth dates back to Charles Darwin’s time, yet scientific advances of the last few decades have radically reshaped that aging picture.”

  • ...16 more annotations...
  • even genuine scientists are human and as such susceptible to the allure of offering up new paradigms (as the historian of science Thomas Kuhn put it)
  • paleontologist Stephen Jay Gould insisted that his conception of “punctuated equilibria” (a kind of Marxist biology that blurred the lines between evolution and revolution), which he developed along with fellow paleontologist Niles Eldredge, upended the traditional Darwinian understanding of how natural selection works.
  • This notion doesn’t constitute a fundamental departure from plain old evolution by natural selection; it simply italicizes that sometimes the process is comparatively rapid, other times slower.
  • In addition, they have long had a peculiar perspective on evolution, because of the limitations of the fossil record
  • Darwin was a pioneering geologist as well as the greatest of all biologists, and his insights were backgrounded by the key concept of uniformitarianism, as advocated by Charles Lyell, his friend and mentor
  • previously regnant paradigm among geologists had been “catastrophism
  • fossil record was therefore seen as reflecting the creation and extinction of new species by an array of dramatic and “unnatural” dei ex machina.
  • Of late, however, uniformitarianism has been on a losing streak. Catastrophism is back, with a bang . . . or a flood, or a burst of extraterrestrial radiation, or an onslaught of unpleasant, previously submerged chemicals
  • This emphasis on catastrophes is the first of a triad of novelties on which “A New History of Life” is based. The second involves an enhanced role for some common but insufficiently appreciated inorganic molecules, notably carbon dioxide, oxygen and hydrogen sulfide.
  • Life didn’t so much unfold smoothly over hundreds of millions of years as lurch chaotically in response to diverse crises and opportunities: too much oxygen, too little carbon dioxide, too little oxygen, too much carbon dioxide, too hot, too cold
  • So far, so good, except that in their eagerness to emphasize what is new and different, the authors teeter on the verge of the same trap as Gould: exaggerating the novelty of their own ideas.
  • Things begin to unravel when it comes to the third leg of Messrs. Ward and Kirschvink’s purported paradigmatic novelty: a supposed role for ecosystems—rain forests, deserts, rivers, coral reefs, deep-sea vents—as units of evolutionary change
  • “While the history of life may be populated by species,” they write, “it has been the evolution of ecosystems that has been the most influential factor in arriving at the modern-day assemblage of life. . . . [W]e know that on occasion in the deep past entirely new ecosystems appear, populated by new kinds of life.” True enough, but it is those “new kinds of life,” not whole ecosystems, upon which natural selection acts.
  • One of the most common popular misconceptions about evolution is that it proceeds “for the good of the species.”
  • The problem is that smaller, nimbler units are far more likely to reproduce differentially than are larger, clumsier, more heterogeneous ones. Insofar as ecosystems are consequential for evolution—and doubtless they are—it is because, like occasional catastrophes, they provide the immediate environment within which something not-so-new is acted out.
  • This is natural selection doing its same-old, same-old thing: acting by a statistically potent process of variation combined with selective retention and differential reproduction, a process that necessarily operates within the particular ecosystem that a given lineage occupies.

The herd mentality is all around us - 0 views

  • “Personal space” and the idea of being left alone with one’s thoughts can almost be seen as modern add-ons to what humanity is like, and perhaps more typical of WEIRD (Western, educated, industrialized, rich and democratic) societies than others
  • WEIRD-ness being the coinage of Joseph Henrich, an anthropologist at Harvard and the author of “The WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous.” Reviewing the book for The Times, the Tufts University philosophy professor Daniel Dennett described Henrich’s concept thusly:The world today has billions of inhabitants who have minds strikingly different from ours. Roughly, we weirdos are individualistic, think analytically, believe in free will, take personal responsibility, feel guilt when we misbehave and think nepotism is to be vigorously discouraged, if not outlawed.
  • They (the non-WEIRD majority) identify more strongly with family, tribe, clan and ethnic group, think more “holistically,” take responsibility for what their group does (and publicly punish those who besmirch the group’s honor), feel shame — not guilt — when they misbehave and think nepotism is a natural duty.

  • There are signs that at the same time, so many other people are seeking to countenance diversity of thought, disavowing the comforts of the idea that their view is the only legitimate one and fostering an ideal under which our society frames difference of opinion as a norm rather than a threat. We can see it in aspects of linguistic behavio
  • To us WEIRD-os, by contrast, the ever-stronger purchase of individualism in our intellectual, moral and civic development seems natural. But it’s challenging, perhaps unnatural, to be an individual.
  • That realization makes less shocking to me, albeit utterly dismaying, the many dogmatic behaviors exhibited today that seem outwardly irrational or close to it. The kinds of things that make it seem as if so many of us are, so to speak, losing it are actually signs of how difficult it can be to get past what we seem to be hard-wired for. Fanatic beliefs, furious ideologies and even, potentially, a sense of duty to harm people in the name of certain beliefs reflect the eternal temptation of a sense of belonging to a group, of being part of a larger story, of having a guiding sense of purpose.
  • Casual American English, in ways we’re not always conscious of, is more overt in allowing room for disagreement than it used to be. For example, the use of “like” that so bothers purists is in reality a useful discursive hedge, along with phrases such as “sort of,” “kind of” and “you know.” In conversation, these expressions can be read as subtle indications that someone knows that there are other ways to view things, and to be too categorical is to imply a certainty that all may not share.
  • Moral Courage College, an alternative to the D.E.I. ritual, a program offering training in how to productively grapple with the wide range of views and experiences found in most workplaces, as well as colleges, universities and even K-12 schools
  • a method called Diversity Without Division. “This program doesn’t tell anybody what to think or believe,” she has said, “it teaches everybody to lower their emotional defenses so that contentious issues can be turned into constructive conversations and healthy teamwork.”
  • Courage is allowing that your own view may be but one legitimate one among many, that there are no easy answers, and that being your own self is a more gracious existence than joining a herd.

Why the Past 10 Years of American Life Have Been Uniquely Stupid - The Atlantic - 0 views

  • Social scientists have identified at least three major forces that collectively bind together successful democracies: social capital (extensive social networks with high levels of trust), strong institutions, and shared stories.
  • Social media has weakened all three.
  • gradually, social-media users became more comfortable sharing intimate details of their lives with strangers and corporations. As I wrote in a 2019 Atlantic article with Tobias Rose-Stockwell, they became more adept at putting on performances and managing their personal brand—activities that might impress others but that do not deepen friendships in the way that a private phone conversation will.

  • the stage was set for the major transformation, which began in 2009: the intensification of viral dynamics.
  • Before 2009, Facebook had given users a simple timeline––a never-ending stream of content generated by their friends and connections, with the newest posts at the top and the oldest ones at the bottom
  • That began to change in 2009, when Facebook offered users a way to publicly “like” posts with the click of a button. That same year, Twitter introduced something even more powerful: the “Retweet” button, which allowed users to publicly endorse a post while also sharing it with all of their followers.
  • “Like” and “Share” buttons quickly became standard features of most other platforms.
  • Facebook developed algorithms to bring each user the content most likely to generate a “like” or some other interaction, eventually including the “share” as well.
  • Later research showed that posts that trigger emotions––especially anger at out-groups––are the most likely to be shared.
  • By 2013, social media had become a new game, with dynamics unlike those in 2008. If you were skillful or lucky, you might create a post that would “go viral” and make you “internet famous”
  • If you blundered, you could find yourself buried in hateful comments. Your posts rode to fame or ignominy based on the clicks of thousands of strangers, and you in turn contributed thousands of clicks to the game.
  • This new game encouraged dishonesty and mob dynamics: Users were guided not just by their true preferences but by their past experiences of reward and punishment,
  • As a social psychologist who studies emotion, morality, and politics, I saw this happening too. The newly tweaked platforms were almost perfectly designed to bring out our most moralistic and least reflective selves. The volume of outrage was shocking.
  • It was just this kind of twitchy and explosive spread of anger that James Madison had tried to protect us from as he was drafting the U.S. Constitution.
  • The Framers of the Constitution were excellent social psychologists. They knew that democracy had an Achilles’ heel because it depended on the collective judgment of the people, and democratic communities are subject to “the turbulency and weakness of unruly passions.”
  • The key to designing a sustainable republic, therefore, was to build in mechanisms to slow things down, cool passions, require compromise, and give leaders some insulation from the mania of the moment while still holding them accountable to the people periodically, on Election Day.
  • The tech companies that enhanced virality from 2009 to 2012 brought us deep into Madison’s nightmare.
  • a less quoted yet equally important insight, about democracy’s vulnerability to triviality.
  • Madison notes that people are so prone to factionalism that “where no substantial occasion presents itself, the most frivolous and fanciful distinctions have been sufficient to kindle their unfriendly passions and excite their most violent conflicts.”
  • Social media has both magnified and weaponized the frivolous.
  • It’s not just the waste of time and scarce attention that matters; it’s the continual chipping-away of trust.
  • a democracy depends on widely internalized acceptance of the legitimacy of rules, norms, and institutions.
  • when citizens lose trust in elected leaders, health authorities, the courts, the police, universities, and the integrity of elections, then every decision becomes contested; every election becomes a life-and-death struggle to save the country from the other side
  • The most recent Edelman Trust Barometer (an international measure of citizens’ trust in government, business, media, and nongovernmental organizations) showed stable and competent autocracies (China and the United Arab Emirates) at the top of the list, while contentious democracies such as the United States, the United Kingdom, Spain, and South Korea scored near the bottom (albeit above Russia).
  • The literature is complex—some studies show benefits, particularly in less developed democracies—but the review found that, on balance, social media amplifies political polarization; foments populism, especially right-wing populism; and is associated with the spread of misinformation.
  • When people lose trust in institutions, they lose trust in the stories told by those institutions. That’s particularly true of the institutions entrusted with the education of children.
  • Facebook and Twitter make it possible for parents to become outraged every day over a new snippet from their children’s history lessons––and math lessons and literature selections, and any new pedagogical shifts anywhere in the country
  • The motives of teachers and administrators come into question, and overreaching laws or curricular reforms sometimes follow, dumbing down education and reducing trust in it further.
  • young people educated in the post-Babel era are less likely to arrive at a coherent story of who we are as a people, and less likely to share any such story with those who attended different schools or who were educated in a different decade.
  • former CIA analyst Martin Gurri predicted these fracturing effects in his 2014 book, The Revolt of the Public. Gurri’s analysis focused on the authority-subverting effects of information’s exponential growth, beginning with the internet in the 1990s. Writing nearly a decade ago, Gurri could already see the power of social media as a universal solvent, breaking down bonds and weakening institutions everywhere it reached.
  • he notes a constructive feature of the pre-digital era: a single “mass audience,” all consuming the same content, as if they were all looking into the same gigantic mirror at the reflection of their own society. I
  • The digital revolution has shattered that mirror, and now the public inhabits those broken pieces of glass. So the public isn’t one thing; it’s highly fragmented, and it’s basically mutually hostile
  • Facebook, Twitter, YouTube, and a few other large platforms unwittingly dissolved the mortar of trust, belief in institutions, and shared stories that had held a large and diverse secular democracy together.
  • I think we can date the fall of the tower to the years between 2011 (Gurri’s focal year of “nihilistic” protests) and 2015, a year marked by the “great awokening” on the left and the ascendancy of Donald Trump on the right.
  • Twitter can overpower all the newspapers in the country, and stories cannot be shared (or at least trusted) across more than a few adjacent fragments—so truth cannot achieve widespread adherence.
  • fter Babel, nothing really means anything anymore––at least not in a way that is durable and on which people widely agree.
  • Politics After Babel
  • “Politics is the art of the possible,” the German statesman Otto von Bismarck said in 1867. In a post-Babel democracy, not much may be possible.
  • The ideological distance between the two parties began increasing faster in the 1990s. Fox News and the 1994 “Republican Revolution” converted the GOP into a more combative party.
  • So cross-party relationships were already strained before 2009. But the enhanced virality of social media thereafter made it more hazardous to be seen fraternizing with the enemy or even failing to attack the enemy with sufficient vigor.
  • What changed in the 2010s? Let’s revisit that Twitter engineer’s metaphor of handing a loaded gun to a 4-year-old. A mean tweet doesn’t kill anyone; it is an attempt to shame or punish someone publicly while broadcasting one’s own virtue, brilliance, or tribal loyalties. It’s more a dart than a bullet
  • from 2009 to 2012, Facebook and Twitter passed out roughly 1 billion dart guns globally. We’ve been shooting one another ever since.
  • “devoted conservatives,” comprised 6 percent of the U.S. population.
  • the warped “accountability” of social media has also brought injustice—and political dysfunction—in three ways.
  • First, the dart guns of social media give more power to trolls and provocateurs while silencing good citizens.
  • a small subset of people on social-media platforms are highly concerned with gaining status and are willing to use aggression to do so.
  • Across eight studies, Bor and Petersen found that being online did not make most people more aggressive or hostile; rather, it allowed a small number of aggressive people to attack a much larger set of victims. Even a small number of jerks were able to dominate discussion forums,
  • Additional research finds that women and Black people are harassed disproportionately, so the digital public square is less welcoming to their voices.
  • Second, the dart guns of social media give more power and voice to the political extremes while reducing the power and voice of the moderate majority.
  • The “Hidden Tribes” study, by the pro-democracy group More in Common, surveyed 8,000 Americans in 2017 and 2018 and identified seven groups that shared beliefs and behaviors.
  • Social media has given voice to some people who had little previously, and it has made it easier to hold powerful people accountable for their misdeeds
  • The group furthest to the left, the “progressive activists,” comprised 8 percent of the population. The progressive activists were by far the most prolific group on social media: 70 percent had shared political content over the previous year. The devoted conservatives followed, at 56 percent.
  • These two extreme groups are similar in surprising ways. They are the whitest and richest of the seven groups, which suggests that America is being torn apart by a battle between two subsets of the elite who are not representative of the broader society.
  • they are the two groups that show the greatest homogeneity in their moral and political attitudes.
  • likely a result of thought-policing on social media:
  • political extremists don’t just shoot darts at their enemies; they spend a lot of their ammunition targeting dissenters or nuanced thinkers on their own team.
  • Finally, by giving everyone a dart gun, social media deputizes everyone to administer justice with no due process. Platforms like Twitter devolve into the Wild West, with no accountability for vigilantes.
  • Enhanced-virality platforms thereby facilitate massive collective punishment for small or imagined offenses, with real-world consequences, including innocent people losing their jobs and being shamed into suicide
  • we don’t get justice and inclusion; we get a society that ignores context, proportionality, mercy, and truth.
  • Since the tower fell, debates of all kinds have grown more and more confused. The most pervasive obstacle to good thinking is confirmation bias, which refers to the human tendency to search only for evidence that confirms our preferred beliefs
  • search engines were supercharging confirmation bias, making it far easier for people to find evidence for absurd beliefs and conspiracy theorie
  • The most reliable cure for confirmation bias is interaction with people who don’t share your beliefs. They confront you with counterevidence and counterargument.
  • In his book The Constitution of Knowledge, Jonathan Rauch describes the historical breakthrough in which Western societies developed an “epistemic operating system”—that is, a set of institutions for generating knowledge from the interactions of biased and cognitively flawed individuals
  • English law developed the adversarial system so that biased advocates could present both sides of a case to an impartial jury.
  • Newspapers full of lies evolved into professional journalistic enterprises, with norms that required seeking out multiple sides of a story, followed by editorial review, followed by fact-checking.
  • Universities evolved from cloistered medieval institutions into research powerhouses, creating a structure in which scholars put forth evidence-backed claims with the knowledge that other scholars around the world would be motivated to gain prestige by finding contrary evidence.
  • Part of America’s greatness in the 20th century came from having developed the most capable, vibrant, and productive network of knowledge-producing institutions in all of human history
  • But this arrangement, Rauch notes, “is not self-maintaining; it relies on an array of sometimes delicate social settings and understandings, and those need to be understood, affirmed, and protected.”
  • This, I believe, is what happened to many of America’s key institutions in the mid-to-late 2010s. They got stupider en masse because social media instilled in their members a chronic fear of getting darted
  • it was so pervasive that it established new behavioral norms backed by new policies seemingly overnight
  • Participants in our key institutions began self-censoring to an unhealthy degree, holding back critiques of policies and ideas—even those presented in class by their students—that they believed to be ill-supported or wrong.
  • The stupefying process plays out differently on the right and the left because their activist wings subscribe to different narratives with different sacred values.
  • The “Hidden Tribes” study tells us that the “devoted conservatives” score highest on beliefs related to authoritarianism. They share a narrative in which America is eternally under threat from enemies outside and subversives within; they see life as a battle between patriots and traitors.
  • they are psychologically different from the larger group of “traditional conservatives” (19 percent of the population), who emphasize order, decorum, and slow rather than radical change.
  • The traditional punishment for treason is death, hence the battle cry on January 6: “Hang Mike Pence.”
  • Right-wing death threats, many delivered by anonymous accounts, are proving effective in cowing traditional conservatives
  • The wave of threats delivered to dissenting Republican members of Congress has similarly pushed many of the remaining moderates to quit or go silent, giving us a party ever more divorced from the conservative tradition, constitutional responsibility, and reality.
  • The stupidity on the right is most visible in the many conspiracy theories spreading across right-wing media and now into Congress.
  • The Democrats have also been hit hard by structural stupidity, though in a different way. In the Democratic Party, the struggle between the progressive wing and the more moderate factions is open and ongoing, and often the moderates win.
  • The problem is that the left controls the commanding heights of the culture: universities, news organizations, Hollywood, art museums, advertising, much of Silicon Valley, and the teachers’ unions and teaching colleges that shape K–12 education. And in many of those institutions, dissent has been stifled:
  • Liberals in the late 20th century shared a belief that the sociologist Christian Smith called the “liberal progress” narrative, in which America used to be horrifically unjust and repressive, but, thanks to the struggles of activists and heroes, has made (and continues to make) progress toward realizing the noble promise of its founding.
  • It is also the view of the “traditional liberals” in the “Hidden Tribes” study (11 percent of the population), who have strong humanitarian values, are older than average, and are largely the people leading America’s cultural and intellectual institutions.
  • when the newly viralized social-media platforms gave everyone a dart gun, it was younger progressive activists who did the most shooting, and they aimed a disproportionate number of their darts at these older liberal leaders.
  • Confused and fearful, the leaders rarely challenged the activists or their nonliberal narrative in which life at every institution is an eternal battle among identity groups over a zero-sum pie, and the people on top got there by oppressing the people on the bottom. This new narrative is rigidly egalitarian––focused on equality of outcomes, not of rights or opportunities. It is unconcerned with individual rights.
  • The universal charge against people who disagree with this narrative is not “traitor”; it is “racist,” “transphobe,” “Karen,” or some related scarlet letter marking the perpetrator as one who hates or harms a marginalized group.
  • The punishment that feels right for such crimes is not execution; it is public shaming and social death.
  • anyone on Twitter had already seen dozens of examples teaching the basic lesson: Don’t question your own side’s beliefs, policies, or actions. And when traditional liberals go silent, as so many did in the summer of 2020, the progressive activists’ more radical narrative takes over as the governing narrative of an organization.
  • This is why so many epistemic institutions seemed to “go woke” in rapid succession that year and the next, beginning with a wave of controversies and resignations at The New York Times and other newspapers, and continuing on to social-justice pronouncements by groups of doctors and medical associations
  • The problem is structural. Thanks to enhanced-virality social media, dissent is punished within many of our institutions, which means that bad ideas get elevated into official policy.
  • In a 2018 interview, Steve Bannon, the former adviser to Donald Trump, said that the way to deal with the media is “to flood the zone with shit.” He was describing the “firehose of falsehood” tactic pioneered by Russian disinformation programs to keep Americans confused, disoriented, and angry.
  • artificial intelligence is close to enabling the limitless spread of highly believable disinformation. The AI program GPT-3 is already so good that you can give it a topic and a tone and it will spit out as many essays as you like, typically with perfect grammar and a surprising level of coherence.
  • Renée DiResta, the research manager at the Stanford Internet Observatory, explained that spreading falsehoods—whether through text, images, or deep-fake videos—will quickly become inconceivably easy. (She co-wrote the essay with GPT-3.)
  • American factions won’t be the only ones using AI and social media to generate attack content; our adversaries will too.
  • In the 20th century, America’s shared identity as the country leading the fight to make the world safe for democracy was a strong force that helped keep the culture and the polity together.
  • In the 21st century, America’s tech companies have rewired the world and created products that now appear to be corrosive to democracy, obstacles to shared understanding, and destroyers of the modern tower.
  • What changes are needed?
  • I can suggest three categories of reforms––three goals that must be achieved if democracy is to remain viable in the post-Babel era.
  • We must harden democratic institutions so that they can withstand chronic anger and mistrust, reform social media so that it becomes less socially corrosive, and better prepare the next generation for democratic citizenship in this new age.
  • Harden Democratic Institutions
  • we must reform key institutions so that they can continue to function even if levels of anger, misinformation, and violence increase far above those we have today.
  • Reforms should reduce the outsize influence of angry extremists and make legislators more responsive to the average voter in their district.
  • One example of such a reform is to end closed party primaries, replacing them with a single, nonpartisan, open primary from which the top several candidates advance to a general election that also uses ranked-choice voting
  • A second way to harden democratic institutions is to reduce the power of either political party to game the system in its favor, for example by drawing its preferred electoral districts or selecting the officials who will supervise elections
  • These jobs should all be done in a nonpartisan way.
  • Reform Social Media
  • Social media’s empowerment of the far left, the far right, domestic trolls, and foreign agents is creating a system that looks less like democracy and more like rule by the most aggressive.
  • it is within our power to reduce social media’s ability to dissolve trust and foment structural stupidity. Reforms should limit the platforms’ amplification of the aggressive fringes while giving more voice to what More in Common calls “the exhausted majority.”
  • the main problem with social media is not that some people post fake or toxic stuff; it’s that fake and outrage-inducing content can now attain a level of reach and influence that was not possible before
  • Perhaps the biggest single change that would reduce the toxicity of existing platforms would be user verification as a precondition for gaining the algorithmic amplification that social media offers.
  • One of the first orders of business should be compelling the platforms to share their data and their algorithms with academic researchers.
  • Prepare the Next Generation
  • Childhood has become more tightly circumscribed in recent generations––with less opportunity for free, unstructured play; less unsupervised time outside; more time online. Whatever else the effects of these shifts, they have likely impeded the development of abilities needed for effective self-governance for many young adults
  • Depression makes people less likely to want to engage with new people, ideas, and experiences. Anxiety makes new things seem more threatening. As these conditions have risen and as the lessons on nuanced social behavior learned through free play have been delayed, tolerance for diverse viewpoints and the ability to work out disputes have diminished among many young people
  • Students did not just say that they disagreed with visiting speakers; some said that those lectures would be dangerous, emotionally devastating, a form of violence. Because rates of teen depression and anxiety have continued to rise into the 2020s, we should expect these views to continue in the generations to follow, and indeed to become more severe.
  • The most important change we can make to reduce the damaging effects of social media on children is to delay entry until they have passed through puberty.
  • The age should be raised to at least 16, and companies should be held responsible for enforcing it.
  • et them out to play. Stop starving children of the experiences they most need to become good citizens: free play in mixed-age groups of children with minimal adult supervision
  • while social media has eroded the art of association throughout society, it may be leaving its deepest and most enduring marks on adolescents. A surge in rates of anxiety, depression, and self-harm among American teens began suddenly in the early 2010s. (The same thing happened to Canadian and British teens, at the same time.) The cause is not known, but the timing points to social media as a substantial contributor—the surge began just as the large majority of American teens became daily users of the major platforms.
  • What would it be like to live in Babel in the days after its destruction? We know. It is a time of confusion and loss. But it is also a time to reflect, listen, and build.
  • In recent years, Americans have started hundreds of groups and organizations dedicated to building trust and friendship across the political divide, including BridgeUSA, Braver Angels (on whose board I serve), and many others listed at BridgeAlliance.us. We cannot expect Congress and the tech companies to save us. We must change ourselves and our communities.
  • when we look away from our dysfunctional federal government, disconnect from social media, and talk with our neighbors directly, things seem more hopeful. Most Americans in the More in Common report are members of the “exhausted majority,” which is tired of the fighting and is willing to listen to the other side and compromise. Most Americans now see that social media is having a negative impact on the country, and are becoming more aware of its damaging effects on children.

The Duck of Minerva: Two certification systems - 0 views

  • Cohen outlined a vision of 'Net-enabled scholarly publishing that I can only think to call the aggregation model: editorial committees scanning the 'Net to find the most interesting scholarly content in a given field or discipline, and highlighting it through websites and e-mail blasts that hearken back to the early days when weblogs were literally just collections of links with one- or two-sentence summaries attached. (An example, edited by Cohen and some of his associates: Digital Humanities Now.) Some of that work consists of traditional books and articles, but much of it consists of blog posts, online debates, etc. This model gives us scholarly work from the bottom up, instead of generating published scholarly work by tossing a piece into the random crapshoot of putatively blind peer-review and crossing your fingers to see what happens. It also gives us scholarly work that can be certified as such by the collective deliberation of the community, which "votes" for pieces and ideas by reading them, recirculating them, linking to them, and other signs of interest and approval that can be easily tracked with traffic-tracing tools. And then, on top of that editorial aggregation -- Cohen made a great point that this kind of aggregation shouldn't be fully automated, because automated tools reward "loudmouths" and popular voices that just get retweeted a lot; human editors can do a lot to surface novel insights and new voices -- an open-access journal that curates the best of those linked items into published pieces, perhaps with some revisions and peer review/commentary.

Review: In 'The End of Average,' Cheers for Individual Complexity - The New York Times - 1 views

  • All of us want to be normal, yet none of us want to be average.
  • We march through life measuring ourselves on one scale after another
  • Must the tyranny of the group rule us from cradle to grave? Absolutely not, says Todd Rose in a subversive and readable introduction to what has been called the new science of the individual.
  • ...12 more annotations...
  • Dr. Rose lays the blame for our modern obsession directly at the feet of Adolphe Quetelet, a 19th-century Belgian mathematician. Quetelet was an early data cruncher, the first to apply statistical tools to large groups of people
  • Among his accomplishments was devising the body mass index, a ratio of weight to height that we still use to decide if people are too big or small. For him, the average was the optimal; normal was the best thing any human could ever possibly be.
  • Not so for one of his intellectual heirs, Francis Galton of Britain, who agreed that averages were excellent tools for understanding individuals. Ultimately, though, he came to the conclusion that the average defined not the optimal but simply the mediocre, a mark to be measured only so that it could be surpassed.

His argument will resonate in many other contexts, though: Readers will be moved to examine their own averagerian prejudices, most so ingrained as to be almost invisible, all worthy of review.

Google Devising Radical Search Changes to Beat Back AI Rivals - The New York Times - 0 views

  • Google’s employees were shocked when they learned in March that the South Korean consumer electronics giant Samsung was considering replacing Google with Microsoft’s Bing as the default search engine on its devices.
  • Google’s reaction to the Samsung threat was “panic,” according to internal messages reviewed by The New York Times. An estimated $3 billion in annual revenue was at stake with the Samsung contract. An additional $20 billion is tied to a similar Apple contract that will be up for renewal this year.
  • A.I. competitors like the new Bing are quickly becoming the most serious threat to Google’s search business in 25 years, and in response, Google is racing to build an all-new search engine powered by the technology. It is also upgrading the existing one with A.I. features, according to internal documents reviewed by The Times.

  • The Samsung threat represented the first potential crack in Google’s seemingly impregnable search business, which was worth $162 billion last year.
  • Modernizing its search engine has become an obsession at Google, and the planned changes could put new A.I. technology in phones and homes all over the world.
  • Google has been worried about A.I.-powered competitors since OpenAI, a San Francisco start-up that is working with Microsoft, demonstrated a chatbot called ChatGPT in November. About two weeks later, Google created a task force in its search division to start building A.I. products,
  • Google has been doing A.I. research for years. Its DeepMind lab in London is considered one of the best A.I. research centers in the world, and the company has been a pioneer with A.I. projects, such as self-driving cars and the so-called large language models that are used in the development of chatbots. In recent years, Google has used large language models to improve the quality of its search results, but held off on fully adopting A.I. because it has been prone to generating false and biased statements.
  • Now the priority is winning control of the industry’s next big thing. Last month, Google released its own chatbot, Bard, but the technology received mixed reviews.
  • The system would learn what users want to know based on what they’re searching when they begin using it. And it would offer lists of preselected options for objects to buy, information to research and other information. It would also be more conversational — a bit like chatting with a helpful person.
  • Magi would keep ads in the mix of search results. Search queries that could lead to a financial transaction, such as buying shoes or booking a flight, for example, would still feature ads on their results pages.
  • Last week, Google invited some employees to test Magi’s features, and it has encouraged them to ask the search engine follow-up questions to judge its ability to hold a conversation. Google is expected to release the tools to the public next month and add more features in the fall, according to the planning document.
  • The company plans to initially release the features to a maximum of one million people. That number should progressively increase to 30 million by the end of the year. The features will be available exclusively in the United States.
  • Google has also explored efforts to let people use Google Earth’s mapping technology with help from A.I. and search for music through a conversation with a chatbot
  • A tool called GIFI would use A.I. to generate images in Google Image results.
  • Tivoli Tutor, would teach users a new language through open-ended A.I. text conversations.
  • Yet another product, Searchalong, would let users ask a chatbot questions while surfing the web through Google’s Chrome browser. People might ask the chatbot for activities near an Airbnb rental, for example, and the A.I. would scan the page and the rest of the internet for a response.
  • “If we are the leading search engine and this is a new attribute, a new feature, a new characteristic of search engines, we want to make sure that we’re in this race as well,”
