The contrary insistence that the glories of art and thought are not evolutionary adaptations, or that the mind is not the brain, or that love is not just biology’s bait for sex, now amounts to a kind of heresy.

Greif’s book is a prehistory of our predicament, of our own “crisis of man.” (The “man” is archaic, the “crisis” is not.) It recognizes that the intellectual history of modernity may be written in part as the epic tale of a series of rebellions against humanism

We are not becoming transhumanists, obviously. We are too singular for the Singularity. But are we becoming posthumanists?

In American culture right now, as I say, the worldview that is ascendant may be described as posthumanism.

The posthumanism of the 1970s and 1980s was more insular, an academic affair of “theory,” an insurgency of professors; our posthumanism is a way of life, a social fate.

In “The Age of the Crisis of Man: Thought and Fiction in America, 1933-1973,” the gifted essayist Mark Greif, who reveals himself to be also a skillful historian of ideas, charts the history of the 20th-century reckonings with the definition of “man.

Here is his conclusion: “Anytime your inquiries lead you to say, ‘At this moment we must ask and decide who we fundamentally are, our solution and salvation must lie in a new picture of ourselves and humanity, this is our profound responsibility and a new opportunity’ — just stop.” Greif seems not to realize that his own book is a lasting monument to precisely such inquiry, and to its grandeur

“Answer, rather, the practical matters,” he counsels, in accordance with the current pragmatist orthodoxy. “Find the immediate actions necessary to achieve an aim.” But before an aim is achieved, should it not be justified? And the activity of justification may require a “picture of ourselves.” Don’t just stop. Think harder. Get it right.

— but rather in the appeal to their defiantly nonutilitarian character, so that individuals can know more than how things work, and develop their powers of discernment and judgment, their competence in matters of truth and goodness and beauty, to equip themselves adequately for the choices and the crucibles of private and public life.

Who has not felt superior to humanism? It is the cheapest target of all: Humanism is sentimental, flabby, bourgeois, hypocritical, complacent, middlebrow, liberal, sanctimonious, constricting and often an alibi for power

what is humanism? For a start, humanism is not the antithesis of religion, as Pope Francis is exquisitely demonstrating

The worldview takes many forms: a philosophical claim about the centrality of humankind to the universe, and about the irreducibility of the human difference to any aspect of our animality

Here is a humanist proposition for the age of Google: The processing of information is not the highest aim to which the human spirit can aspire, and neither is competitiveness in a global economy. The character of our society cannot be determined by engineers.

And posthumanism? It elects to understand the world in terms of impersonal forces and structures, and to deny the importance, and even the legitimacy, of human agency.

There have been humane posthumanists and there have been inhumane humanists. But the inhumanity of humanists may be refuted on the basis of their own worldview

the condemnation of cruelty toward “man the machine,” to borrow the old but enduring notion of an 18th-century French materialist, requires the importation of another framework of judgment. The same is true about universalism, which every critic of humanism has arraigned for its failure to live up to the promise of a perfect inclusiveness

there has never been a universalism that did not exclude. Yet the same is plainly the case about every particularism, which is nothing but a doctrine of exclusion; and the correction of particularism, the extension of its concept and its care, cannot be accomplished in its own name. It requires an idea from outside, an idea external to itself, a universalistic idea, a humanistic idea.

Asking universalism to keep faith with its own principles is a perennial activity of moral life. Asking particularism to keep faith with its own principles is asking for trouble.

there is no more urgent task for American intellectuals and writers than to think critically about the salience, even the tyranny, of technology in individual and collective life

a methodological claim about the most illuminating way to explain history and human affairs, and about the essential inability of the natural sciences to offer a satisfactory explanation; a moral claim about the priority, and the universal nature, of certain values, not least tolerance and compassion

“Our very mastery seems to escape our mastery,” Michel Serres has anxiously remarked. “How can we dominate our domination; how can we master our own mastery?”

universal accessibility is not the end of the story, it is the beginning. The humanistic methods that were practiced before digitalization will be even more urgent after digitalization, because we will need help in navigating the unprecedented welter

Searches for keywords will not provide contexts for keywords. Patterns that are revealed by searches will not identify their own causes and reasons

The new order will not relieve us of the old burdens, and the old pleasures, of erudition and interpretation.

Is all this — is humanism — sentimental? But sentimentality is not always a counterfeit emotion. Sometimes sentiment is warranted by reality.

The persistence of humanism through the centuries, in the face of formidable intellectual and social obstacles, has been owed to the truth of its representations of our complexly beating hearts, and to the guidance that it has offered, in its variegated and conflicting versions, for a soulful and sensitive existence

a complacent humanist is a humanist who has not read his books closely, since they teach disquiet and difficulty. In a society rife with theories and practices that flatten and shrink and chill the human subject, the humanist is the dissenter.

Haidt isn’t helping himself any. The term “culture of victimhood” reminds many people of the “snowflake” insult, the idea than anyone from a marginalized background who complains about injustice is really just self-involved and weak.

I find his predictions about how these dynamics will somehow undermine American capitalism to be unconvincing, running towards bizarre. If social media is making our kids depressed and anxious, that is the reason to be concerned, not some tangled logic about national greatness.

I think that suffering is the only truly universal endowment of the human species.

ecause Haidt talked about a culture of victimhood, he was immediately coded as right-wing, which is to say on the wrong side of the culture war

(The piece notes that the age at which children are allowed to play outside alone has moved from 7 or 8 to 10 or 12 in short order.)

the critics of someone like Haidt, the most coherent criticism they mount is that talk of toughness and resilience can be used opportunistically to dismiss demands for justice. “You just need to toughen up” is not, obviously, a constructive, good-faith response to a demand that the police stop killing unarmed Black people

I don’t think that’s the version Haidt is articulating

Yes, we must do all we can to reduce injustice, and we need to be compassionate to everyone. But we also need to understand that no political movement, no matter how effective, can ever end suffering and thus obviate the need for resilience.

I’m really not a fan of therapy culture, where the imperatives and vocabulary and purpose of therapy are now assumed to be necessary in every domain of human affairs. But that’s not because I think therapy is bad; I think therapy, as therapy, is very good. It’s because I think everything can’t be therapy, and the effort to make everything therapy will have the perverse effect of making nothing therapy.

hose promises have also fueled anxiety over how people will be able to compete for jobs outsourced to eerily refined machines or trust the accuracy of what they see online.

Officials with the San Francisco lab said GPT-4’s “multimodal” training across text and images would allow it to escape the chat box and more fully emulate a world of color and imagery, surpassing ChatGPT in its “advanced reasoning capabilities.”

A person could upload an image and GPT-4 could caption it for them, describing the objects and scene.

AI language models often confidently offer wrong answers because they are designed to spit out cogent phrases, not actual facts. And because they have been trained on internet text and imagery, they have also learned to emulate human biases of race, gender, religion and class.

GPT-4 still makes many of the errors of previous versions, including “hallucinating” nonsense, perpetuating social biases and offering bad advice. It also lacks knowledge of events that happened after about September 2021, when its training data was finalized, and “does not learn from its experience,” limiting people’s ability to teach it new things.

Microsoft has invested billions of dollars in OpenAI in the hope its technology will become a secret weapon for its workplace software, search engine and other online ambitions. It has marketed the technology as a super-efficient companion that can handle mindless work and free people for creative pursuits, helping one software developer to do the work of an entire team or allowing a mom-and-pop shop to design a professional advertising campaign without outside help.

it could lead to business models and creative ventures no one can predict.

sparked criticism that the companies are rushing to exploit an untested, unregulated and unpredictable technology that could deceive people, undermine artists’ work and lead to real-world harm.

the company held back the feature to better understand potential risks. As one example, she said, the model might be able to look at an image of a big group of people and offer up known information about them, including their identities — a possible facial recognition use case that could be used for mass surveillance.

OpenAI researchers wrote, “As GPT-4 and AI systems like it are adopted more widely,” they “will have even greater potential to reinforce entire ideologies, worldviews, truths and untruths, and to cement them or lock them in.”

“We can agree as a society broadly on some harms that a model should not contribute to,” such as building a nuclear bomb or generating child sexual abuse material, she said. “But many harms are nuanced and primarily affect marginalized groups,” she added, and those harmful biases, especially across other languages, “cannot be a secondary consideration in performance.”

OpenAI said its new model would be able to handle more than 25,000 words of text, a leap forward that could facilitate longer conversations and allow for the searching and analysis of long documents.

OpenAI developers said GPT-4 was more likely to provide factual responses and less likely to refuse harmless requests

Duolingo, the language learning app, has already used GPT-4 to introduce new features, such as an AI conversation partner and a tool that tells users why an answer was incorrect.

The company did not share evaluations around bias that have become increasingly common after pressure from AI ethicists.

GPT-4 will have competition in the growing field of multisensory AI. DeepMind, an AI firm owned by Google’s parent company Alphabet, last year released a “generalist” model named Gato that can describe images and play video games. And Google this month released a multimodal system, PaLM-E, that folded AI vision and language expertise into a one-armed robot on wheels: If someone told it to go fetch some chips, for instance, it could comprehend the request, wheel over to a drawer and choose the right bag.

The systems, though — as critics and the AI researchers are quick to point out — are merely repeating patterns and associations found in their training data without a clear understanding of what it’s saying or when it’s wrong.

GPT-4, the fourth “generative pre-trained transformer” since OpenAI’s first release in 2018, relies on a breakthrough neural-network technique in 2017 known as the transformer that rapidly advanced how AI systems can analyze patterns in human speech and imagery.

The systems are “pre-trained” by analyzing trillions of words and images taken from across the internet: news articles, restaurant reviews and message-board arguments; memes, family photos and works of art.

Giant supercomputer clusters of graphics processing chips are mapped out their statistical patterns — learning which words tended to follow each other in phrases, for instance — so that the AI can mimic those patterns, automatically crafting long passages of text or detailed images, one word or pixel at a time.

In 2019, the company refused to publicly release GPT-2, saying it was so good they were concerned about the “malicious applications” of its use, from automated spam avalanches to mass impersonation and disinformation campaigns.

Altman has also marketed OpenAI’s vision with the aura of science fiction come to life. In a blog post last month, he said the company was planning for ways to ensure that “all of humanity” benefits from “artificial general intelligence,” or AGI — an industry term for the still-fantastical idea of an AI superintelligence that is generally as smart as, or smarter than, the humans themselves.

. The implicit lesson is that grown-ups aren’t infallible. It’s OK to laugh at them and it’s OK to feel compassion for them and it’s even OK to feel sorry for them on occasion.

The adult figures in children’s literature are also frequently outsiders or eccentrics in some way, and quite often subject to ridicule

yes, adults are often the Other — which makes them a mystery and a curiosity. Literature offers insight into these occasionally intimidating creatures.

In real life, children revere adults and they fear them. It only follows, then, that they appreciate when adult characters behave admirably but also delight in seeing the consequences — especially when rendered with humor — when they don’t.

Nursery rhymes, folk tales, myths and legends overwhelmingly cast adults as their central characters — and have endured for good reason

In somewhat later tales, children investigated crimes alongside Sherlock Holmes, adventured through Narnia, inhabited Oz and traversed Middle-earth. Grown-up heroes can be hobbits, or rabbits (“Watership Down”), badgers or moles (“The Wind in the Willows”). Children join them no matter what because they like to be in league with their protagonists and by extension, their authors.

In children’s books with adult heroes, children get to conspire alongside their elders. Defying the too-often adversarial relationship between adults and children in literature, such books enable children to see that adults are perfectly capable of occupying their shared world with less antagonism — as partners in life, in love and in adventure.

Let's consider a case in which Ulfelder argues there is insufficient data to render a prediction -- North Korea. There is no official data on North Korean GDP, so what can we do? It turns out that the same data science approaches that were used to aggregate polls have other uses as well. One is the imputation of missing data. Yes, even when it is all missing. The basic idea is to use the general correlations among data that you do have to provide an aggregate way of estimating information that we don't have.

As it turned out, in this month's election public opinion polls were considerably more precise than the fundamentals. The fundamentals were not always providing bad predictions, but better is better.

In 2012 there were two types of models: one type based on fundamentals such as economic growth and unemployment and another based on public opinion surveys

There is a tradition in world politics to go either back until the Congress of Vienna (when there were fewer than two dozen independent countries) or to the early 1950s after the end of the Second World War. But in reality, there is no need to do this for most studies.

Ulfelder tells us that "when it comes to predicting major political crises like wars, coups, and popular uprisings, there are many plausible predictors for which we don't have any data at all, and much of what we do have is too sparse or too noisy to incorporate into carefully designed forecasting models." But this is true only for the old style of models based on annual data for countries. If we are willing to face data that are collected in rhythm with the phenomena we are studying, this is not the case

Moreover, when they attempt to give their expert knowledge for policy decisions, conservatives will choose to ignore the evidence, claiming a liberal bias.

most of the bad news is the potential impact on scientists. Why? Because scientists, he believes -- once perceived by Republicans to be a Democratic interest group -- will lose bipartisan support for federal science funding.

this sort of thinking might well be bad for scientists, but is simply dangerous for the country. As professionals, scientists should not be put into a subservient place by politicians and ideologues. They should never be felt that their advice might well be attached to carrots or sticks.

Political choices can be made after the evidence is presented, but the evidence should stand for what it is. If the evidence itself is rejected by politicians -- as is currently going on -- then the ignorance of the political class should indeed be exposed, and all threats resisted.

This might seem to be a diatribe against conservatives. But really this criticism is aimed at all unscientific thinking.

there are a number on the left who have their own dogmatic beliefs; the most notable are unscientific theories with regard to the dangers of vaccinations, genetically modified produce, or nuclear energy.

What you do is to take the different bits of material which you have gathered and feel them all over, as it were, with the tentacles of the mind. You take one fact, turn it this way and that, look at it in different lights, and feel for the meaning of it. You bring two facts together and see how they fit. What you are seeking now is the relationship, a synthesis where everything will come together in a neat combination, like a jig-saw puzzle.

Then and only then, Young promises, everything will click in the fourth stage of the seemingly serendipitous a-ha! moment: Out of nowhere the Idea will appear. It will come to you when you are least expecting it

In his third stage of the creative process, Young stresses the importance of making absolutely “no effort of a direct nature”: It is important to realize that this is just as definite and just as necessary a stage in the process as the two preceding ones. What you have to do at this time, apparently, is to turn the problem over to your unconscious mind and let it work while you sleep.

[W]hen you reach this third stage in the production of an idea, drop the problem completely and turn to whatever stimulates your imagination and emotions. Listen to music, go to the theater or movies, read poetry or a detective story.

articulates the increasing importance of quality information filters in our modern information diet. This notion of gathering raw material is the first step in his outline of the creative process:

Young calls the last stage “the cold, gray dawn of the morning after,” when your newborn idea has to face reality: It requires a deal of patient working over to make most ideas fit the exact conditions, or the practical exigencies, under which they must work. And here is where many good ideas are lost. The idea man, like the inventor, is often not patient enough or practical enough to go through with this adapting part of the process. But it has to be done if you are to put ideas to work in a work-a-day world. Do not make the mistake of holding your idea close to your chest at this stage. Submit it to the criticism of the judicious. When you do, a surprising thing will happen. You will find that a good idea has, as it were, self-expanding qualities. It stimulates those who see it to add to it. Thus possibilities in it which you have overlooked will come to light.

what’s perhaps most interesting is the following note he made to the postscript of a reprint: From my own further experience in advertising, government, and public affairs I find no essential points which I would modify in the idea-producing process. There is one, however, on which I would put greater emphasis. This is as to the store of general materials in the idea-producer’s reservoir. […] I am convinced, however, that you gather this vicarious experience best, not when you are boning up on it for an immediate purpose, but when you are pursuing it as an end in itself.

Fang said retractions may be rising because it is simply easier to cheat in an era of digital images, which can be easily manipulated. But he said the increase is caused at least in part by the growing competition for publication and for NIH grant money.He noted that in the 1960s, about two out of three NIH grant requests were funded; today, the success rate for applicants for research funding is about one in five. At the same time, getting work published in the most esteemed journals, such as Nature, has become a “fetish” for some scientists, Fang said.

many observers note that universities and journals, while sometimes agreeable to admitting small mistakes, are at times loath to reveal that the essence of published work was simply wrong.“The reader of scientific information is at the mercy of the scientific institution to investigate or not,” said Adam Marcus, who with Ivan Oransky founded the blog Retraction Watch in 2010. In this case, Marcus said, “if Hopkins doesn’t want to move, we may not find out what is happening for two or three years.”

The trouble is that a delayed response — or none at all — leaves other scientists to build upon shaky work. Fang said he has talked to researchers who have lost months by relying on results that proved impossible to reproduce.Moreover, as Marcus and Oransky have noted, much of the research is funded by taxpayers. Yet when retractions are done, they are done quietly and “live in obscurity,” meaning taxpayers are unlikely to find out that their money may have been wasted.

there’s that exquisite verse, one of the most beautiful in the Bible, the one that says if God cares deeply about sparrows, don’t you think He cares about you? One is so accustomed to dwelling on the second, human, half of the equation, the comforting part, but when you put your hand over that and consider only the first, it’s a little startling: God cares deeply about the sparrows. Not just that, He cares about them individually. “Are not five sparrows sold for two pennies?” Jesus says. “Yet not one of them is forgotten in God’s sight.”

The modern conversation on animal consciousness proceeds, with the rest of the Enlightenment, from the mind of René Descartes, whose take on animals was vividly (and approvingly) paraphrased by the French philosopher Nicolas Malebranche: they “eat without pleasure, cry without pain, grow without knowing it; they desire nothing, fear nothing, know nothing.” Descartes’ term for them was automata

In On the Origin of Species, Charles Darwin made the intriguing claim that among the naturalists he knew it was consistently the case that the better a researcher got to know a certain species, the more each individual animal’s actions appeared attributable to “reason and the less to unlearnt instinct.” The more you knew, the more you suspected that they were rational. That marks an important pivot, that thought, insofar as it took place in the mind of someone devoted to extremely close and meticulous study of living animals, a mind that had trained itself not to sentimentalize.

The sheer number and variety of experiments carried out in the twentieth century—and with, if anything, a renewed intensity in the twenty-first—exceeds summary. Reasoning, language, neurology, the science of emotions—every chamber where “consciousness” is thought to hide has been probed. Birds and chimps and dolphins have been made to look at themselves in mirrors—to observe whether, on the basis of what they see, they groom or preen (a measure, if somewhat arbitrary, of self-awareness). Dolphins have been found to grieve. Primates have learned symbolic or sign languages and then been interrogated with them. Their answers show thinking but have proved stubbornly open to interpretation on the issue of “consciousness,” with critics warning, as always, about the dangers of anthropomorphism, animal-rights bias, etc.

If we put aside the self-awareness standard—and really, how arbitrary and arrogant is that, to take the attribute of consciousness we happen to possess over all creatures and set it atop the hierarchy, proclaiming it the very definition of consciousness (Georg Christoph Lichtenberg wrote something wise in his notebooks, to the effect of: only a man can draw a self-portrait, but only a man wants to)—it becomes possible to say at least the following: the overwhelming tendency of all this scientific work, of its results, has been toward more consciousness. More species having it, and species having more of it than assumed.

The animal kingdom is symphonic with mental activity, and of its millions of wavelengths, we’re born able to understand the minutest sliver. The least we can do is have a proper respect for our ignorance.

The philosopher Thomas Nagel wrote an essay in 1974 titled, “What Is It Like To Be a Bat?”, in which he put forward perhaps the least overweening, most useful definition of “animal consciousness” ever written, one that channels Spinoza’s phrase about “that nature belonging to him wherein he has his being.” Animal consciousness occurs, Nagel wrote, when “there is something that it is to be that organism—something it is like for the organism.” The strangeness of his syntax carries the genuine texture of the problem. We’ll probably never be able to step far enough outside of our species-reality to say much about what is going on with them, beyond saying how like or unlike us they are. Many things are conscious on the earth, and we are one, and our consciousness feels like this; one of the things it causes us to do is doubt the existence of the consciousness of the other millions of species. But it also allows us to imagine a time when we might stop doing that.

these three convictions do not include the belief that the specific teachings of the Catholic Church provide the fundamental truths of human life.  What I do believe is that these teachings are very helpful for understanding the human condition.  Here I distinguish three domains: metaphysical doctrines about the existence and nature of God, historical accounts from the Bible of how God has intervened in human history to reveal his truth and the ethics of love preached by Jesus.

The ethics of love I revere as the inspiration for so many (Catholics and others) who have led exemplary moral lives.  I don’t say that this ethics is the only exemplary way to live or that we have anything near to an adequate understanding of it.  But I know that it has been a powerful force for good. 

As to the theistic metaphysics, I’m agnostic about it taken literally, but see it as a superb intellectual construction that provides a fruitful context for understanding how our religious and moral experiences are tied to the ethics of love.  The historical stories, I maintain, are best taken as parables illustrating moral and metaphysical teachings.

I reverse this order, putting first the ethics of love as a teaching that directly captivates our moral sensibility, then taking the history and metaphysics as helpful elucidations of the ethics.

Catholicism too has reconciled itself to the Enlightenment view of religion.

First, the Church now explicitly acknowledges the right of an individual’s conscience in religious matters: No one may “be prevented from acting according to his conscience, especially in religious matters”  (“Catechism of the Catholic Church,” citing a decree from the Second Vatican Council).

Second, the Church, in practice, hardly ever excludes from its community those who identity themselves as Catholics but reinterpret central teachings (and perhaps reject less central ones).  The “faithful” who attend Mass, receive the sacraments, send their children to Catholic schools and sometimes even teach theology include many who hold views similar to mine.   Church leaders have in effect agreed that the right to follow one’s conscience includes the right of dissident Catholics to remain members of the Church.

there is deep disagreement within the Church about how its core doctrines, including those about the hierarchy’s authority, should be understood.  With the Second Vatican Council, the hierarchy began a move toward the liberal position, which the successors of John XXIII have tried to reverse.  But history shows that Catholics play in a very long game, and there is no reason to give up hope for a new blossoming of the liberal buds.

Critics outside the Church will ask how I adhere to an institution that has so many deep flaws.  My first response is that the Catholic tradition of thought and practice is the only stance toward religion that, in William James’s phrase, is a “live option” for me — the only place I feel at home.  Simply to renounce it would be, as I said at the outset, to lose my self-respect — to deny part of my moral core.

My second response is that the liberal drive for reform is the best hope of saving the Church.  Its greatest present danger is precisely the loss of the members whom the hierarchy and the rest of the conservative core want to marginalize.  I’m not willing to abandon the Church to them.

The new history of capitalism is less a movement than what proponents call a “cohort”: a loosely linked group of scholars who came of age after the end of the cold war cleared some ideological ground, inspired by work that came before but unbeholden to the questions — like, why didn’t socialism take root in America? — that animated previous generations of labor historians.

the crisis hit, and people started asking, ‘Oh my God, what has Wall Street been doing for the last 100 years?’ ”

While most scholars in the field reject the purely oppositional stance of earlier Marxist history, they also take a distinctly critical view of neoclassical economics, with its tidy mathematical models and crisp axioms about rational actors.

The history of capitalism has also benefited from a surge of new, economically minded scholarship on slavery, with scholars increasingly arguing that Northern factories and Southern plantations were not opposing economic systems, as the old narrative has it, but deeply entwined.

In a paper called “Toxic Debt, Liar Loans and Securitized Human Beings: The Panic of 1837 and the Fate of Slavery,” Edward Baptist, a historian at Cornell, looked at the way small investors across America and Europe snapped up exotic financial instruments based on slave holdings, much as people over the past decade went wild for mortgage-backed securities and collateralized debt obligations — with a similarly disastrous outcome.

Facebook, for all the unprecedented connection it fosters among previously atomized people, fosters a very particular kind of connection: one that is mediated, at all times, by Facebook. And one that therefore makes very particular kinds of assumptions about how and why people connect in the first place. Facebook "connection" is defined -- semantically, at least -- by friendship. ("Facebook friends," "friending people," etc.) While it doesn't assume that every connection is an actual friend, in the narrow and maybe even old-fashioned sense of the word, Facebook's infrastructure does assume esteem among people who friend each other.

The study itself, in fact, is confirming the hypothesis that Rauch and Schanz started with: "We predict," they noted, "that due to potential chronic traits and/or their adaptation to a Facebook culture of shallow processing and agreement, frequent Facebook users are highly susceptible to persuasive messages compared to less frequent users.

This is, to say the least, troubling.

Facebook, as a result, is structured as an aggressively upbeat place.

social complicity. You can argue on Facebook, but it is not really encouraged. And the interactions Facebook fosters as it expands -- the status updates, the information sharing, the news consumption -- stem from that default-positive place. "Like," but not "Dislike." "Recommend," but not "Reject."

That's significant, because Facebook wants to expand from social connection into informational connection. The News Feed as the "personalized newspaper"; the just-introduced Home as a mobile locus of that newspaper.

Heavy users of Facebook tend to use the site because of a desire for social inclusion. In that context, the study suggests, those users are primed to agree with fellow users rather than to criticize the information those users share. And not just in terms of their public interactions, but in terms of their private beliefs. This potent combination -- "a need to connect and an ethos of shallow processing" -- provides a warm, moist breeding ground for the spread of opinions, publicly and not-so-publicly. Racist ones among them.

What will happen if information gets fully social -- according to Facebook's definition of "fully social"? What will take place when the Jack Browns of the world aren't just our friends, but our news sources?

Dr. Arthur Beaudet, a professor at the Baylor College of Medicine and the chairman of its department of molecular and human genetics, applaud the effort. He believes that the acts committed by men like Mr. Lanza and the gunmen in other rampages in recent years — at Columbine High School and in Aurora, Colo., in Norway, in Tucson and at Virginia Tech — are so far off the charts of normal behavior that there must be genetic changes driving them.

Everything known about mental illness, these skeptics say, argues that there are likely to be hundreds of genes involved in extreme violent behavior, not to mention a variety of environmental influences, and that all of these factors can interact in complex and unpredictable ways.

The National Institutes of Health was embroiled in controversy about 20 years ago simply for proposing to study the biological underpinnings of violence. Critics accused researchers of racism and singling out minorities, especially black men.

Studies of people at the far end of a bell curve can be especially informative, because the genetic roots of their conditions can be stark and easy to spot, noted J. H. Pate Skene, a Duke University neurobiologist. “I think doing research on outliers, people at an end of a spectrum on something of concern like violent behavior, is certainly a good idea,” he said, but he advised tempering expectations.

“If we know someone has a 2 percent chance or a 10 percent chance or a 20 percent chance of violent behavior, what would you do with that person?” Dr. Skene said. “They have not been convicted of anything — have not done anything wrong.”

Ultimately, understanding the genetics of violence might enable researchers to find ways to intervene before a person commits a horrific crime. But that goal would be difficult to achieve, and the pursuit of it risks jeopardizing personal liberties.

create guidelines for models which, rather than focusing on BMI, strive to educate the industry and foster a healthy working environment.

"I realized that only legislation can change the situation. There was no time to educate so many people, and the change had be forced on the industry. There was no time to waste, so many girls were dieting to death."

"Certainly I don't believe the modeling industry has caused the rise in eating disorders, but it makes it harder," she says. "It's a difficult recovery environment, worshiping thinness as the beauty ideal."

“As women we are so hard on ourselves physically and emotionally,” Ms. Olive said. “It gets you to stop and think about how we think of ourselves.”

Ms. Brice took issue with the tag line for the ad, “You’re More Beautiful Than You Think.” “I think it makes people much more susceptible to absorbing the subconscious messages,” Ms. Brice said, “that at the heart of it all is that beauty is still what defines women. It is a little hypocritical.”

“What if I did look like that woman on the left?” she said, referring to the less flattering sketches of the women. “There are people that look like that.”

another problem emerged: Other researchers, using seemingly comparable data on debt and growth, couldn’t replicate the Reinhart-Rogoff results.

Correct these oddities and errors, and you get what other researchers have found: some correlation between high debt and slow growth, with no indication of which is causing which, but no sign at all of that 90 percent “threshold.”

Finally, Ms. Reinhart and Mr. Rogoff allowed researchers at the University of Massachusetts to look at their original spreadsheet — and the mystery of the irreproducible results was solved. First, they omitted some data; second, they used unusual and highly questionable statistical procedures; and finally, yes, they made an Excel coding error.

the Reinhart-Rogoff fiasco needs to be seen in the broader context of austerity mania: the obviously intense desire of policy makers, politicians and pundits across the Western world to turn their backs on the unemployed and instead use the economic crisis as an excuse to slash social programs.

What the Reinhart-Rogoff affair shows is the extent to which austerity has been sold on false pretenses. For three years, the turn to austerity has been presented not as a choice but as a necessity. Economic research, austerity advocates insisted, showed that terrible things happen once debt exceeds 90 percent of G.D.P. But “economic research” showed no such thing; a couple of economists made that assertion, while many others disagreed. Policy makers abandoned the unemployed and turned to austerity because they wanted to, not because they had to.

“As women we are so hard on ourselves physically and emotionally,” Ms. Olive said. “It gets you to stop and think about how we think of ourselves.”

After watching the video a few times she wrote a post on her Tumblr site, which has become the dissident voice toward the campaign on social media. In a telephone interview, Ms. Brice took issue with the tag line for the ad, “You’re More Beautiful Than You Think.” “I think it makes people much more susceptible to absorbing the subconscious messages,” Ms. Brice said, “that at the heart of it all is that beauty is still what defines women. It is a little hypocritical.”

Irony — postmodern or any other — is a brief against affirmation, against the unsophisticated embrace of positive (unqualified) values.

No one has seen this more clearly than David Foster Wallace, who complains that irony “serves an exclusively negative function,” but is “singularly unuseful when it comes to replace the hypocrisies it debunks” (“E Unibus Pluram,” Review of Contemporary Fiction, 1993). Irony, he adds, is “unmeaty”; that is, it has nothing solid inside it and is committed to having nothing inside it. Few artists, Wallace says, “dare to try to talk about ways of redeeming what’s wrong, because they’ll look sentimental and naïve to all the weary ironists.” But perhaps there is hope. “The next real … ‘rebels’ … might well emerge as some weird bunch of ‘antirebels,’ born oglers who dare to back away from ironic watching, who have the childish gall actually to endorse single-entendre values. Who treat old untrendy human troubles and emotions with reverence and conviction” (“E Pluribus Unam”).
