"During the summer of 2008, the eminent Notre Dame sociologist Christian Smith led a research team that conducted in-depth interviews with 230 young adults from across America. The interviews were part of a larger study that Smith, Kari Christoffersen, Hilary Davidson, Patricia Snell Herzog and others have been conducting on the state of America's youth. Josh Haner/The New York Times Smith and company asked about the young people's moral lives, and the results are depressing. It's not so much that these young Americans are living lives of sin and debauchery, at least no more than you'd expect from 18- to 23-year-olds. What's disheartening is how bad they are at thinking and talking about moral issues. The interviewers asked open-ended questions about right and wrong, moral dilemmas and the meaning of life. In the rambling answers, which Smith and company recount in a new book, "Lost in Transition," you see the young people groping to say anything sensible on these matters. But they just don't have the categories or vocabulary to do so. "

"RESEARCHERS say they have solved a conundrum about human perception that has stumped philosophers and scientists alike for three centuries. Irish politician William Molyneux first posed the question in a letter to the great British thinker John Locke written 323 years ago. Imagine, Molyneux wrote, that a man blind from birth who has learned to identify objects - a sphere and a cube, for example - only through his sense of touch is suddenly able to see. The puzzle, he continued, is: "Whether he Could, by his Sight, and before he touch them, know which is the Globe and which the Cube?" For philosophers of the time, answering "Molyneux's question", as it became known, would resolve a fundamental uncertainty about the human mind. Empiricists believed that we are born blank slates, and become the sum total of our accumulated experience. So-called "nativists" countered that our minds are, from the outset, pre-stocked with ideas waiting to be activated by sight, sound and touch. If a blind man who miraculously recovered his sight could instantly distinguish the cube from the globe it would mean the knowledge was somehow innate, they argued. More recently, this "nurture vs. nature" debate has found its counterpart in modern neuroscience."

"And this is how the Civil War comes to life for a roomful of fourth-graders in Northern Virginia, 150 years after the nation's deadliest armed conflict began. Agner's reenactment of the landmark naval Battle of Hampton Roads - a tactile lesson the vet­eran teacher dreamed up this year - drew her Fairfax County class into a chapter of American history that has long provoked education debate. The war's sesquicentennial, starting Tuesday with the anniversary of the attack on Fort Sumter in South Carolina, provides a "teachable moment" for schools everywhere. But how and when students learn about slavery and secession, blue and gray, Ulysses S. Grant and Robert E. Lee, Bull Run (or Manassas) and Appomattox varies enormously from state to state, school to school and even teacher to teacher. This year, Virginia learned anew the sensitivity of Civil War education when the state Board of Education withdrew approval of a fourth-grade textbook - "Our Virginia: Past and Present" - that asserted thousands of African Americans fought for the South. Most historians reject that claim. Last year, the Texas State Board of Education voted to require eighth-graders to study the inaugural address of Confederate President Jefferson Davis alongside President Abraham Lincoln's first and second inaugurals and his Gettysburg Address. That was one of many controversial revisions to Texas standards. Jeremy A. Stern, a historian who reviewed state academic standards this year for the Thomas B. Fordham Institute, said differences in the timing and scope of Civil War education across the United States are dramatic. Often, he said, the war is not taught systematically until middle school. "

"In 1990, Thomas J. Bouchard, Jr. and his colleagues at the University of Minnesota published a striking finding: About 70 percent of the variance in IQ found in their particular sample of identical twins was found to be associated with genetic variation. Furthermore, identical twins reared apart were eerily similar to identical twins reared together on various measures of personality, occupational and leisure-time interests, and social attitudes. Bouchard's study, along with many others, has painted a consistent picture: Genes matter. The studies say nothing about how they matter, or which genes matter, but they show quite convincingly that they indeed do matter. Genes vary within any group of people (even among the inhabitants of middle-class in Western society), and this variation contributes to variations in these people's behaviors. Let's be clear: Twin studies have received much criticism. Even though the proliferation of advanced statistical techniques (such as structural equation modeling) and the implementation of additional controls have allayed some of the concerns, they haven't allayed all of the them. Even so, the findings from twin studies should not be understated; it counters many a prevailing belief that we are born into this world as blank slates, completely at the mercy of the external environment. Because our psychological characteristics reflect the physical structures of our brains and because our genes contribute to those physical structures, there are unlikely to be any psychological characteristics that are completely unaffected by our DNA.

"Which of the following people would you say is the most admirable: Mother Teresa, Bill Gates or Norman Borlaug? And which do you think is the least admirable? For most people, it's an easy question. Mother Teresa, famous for ministering to the poor in Calcutta, has been beatified by the Vatican, awarded the Nobel Peace Prize and ranked in an American poll as the most admired person of the 20th century. Bill Gates, infamous for giving us the Microsoft dancing paper clip and the blue screen of death, has been decapitated in effigy in "I Hate Gates" Web sites and hit with a pie in the face. As for Norman Borlaug . . . who the heck is Norman Borlaug? Yet a deeper look might lead you to rethink your answers. Borlaug, father of the "Green Revolution" that used agricultural science to reduce world hunger, has been credited with saving a billion lives, more than anyone else in history. Gates, in deciding what to do with his fortune, crunched the numbers and determined that he could alleviate the most misery by fighting everyday scourges in the developing world like malaria, diarrhea and parasites. Mother Teresa, for her part, extolled the virtue of suffering and ran her well-financed missions accordingly: their sick patrons were offered plenty of prayer but harsh conditions, few analgesics and dangerously primitive medical care. It's not hard to see why the moral reputations of this trio should be so out of line with the good they have done. Mother Teresa was the very embodiment of saintliness: white-clad, sad-eyed, ascetic and often photographed with the wretched of the earth. Gates is a nerd's nerd and the world's richest man, as likely to enter heaven as the proverbial camel squeezing through the needle's eye. And Borlaug, now 93, is an agronomist who has spent his life in labs and nonprofits, seldom walking onto the media stage, and hence into our consciousness, at all. "

"When high school students in Shanghai crack their history textbooks this fall they may be in for a surprise. The new standard world history text drops wars, dynasties and Communist revolutions in favor of colorful tutorials on economics, technology, social customs and globalization. Socialism has been reduced to a single, short chapter in the senior high school history course. Chinese Communism before the economic reform that began in 1979 is covered in a sentence. The text mentions Mao only once - in a chapter on etiquette. Nearly overnight the country's most prosperous schools have shelved the Marxist template that had dominated standard history texts since the 1950's. The changes passed high-level scrutiny, the authors say, and are part of a broader effort to promote a more stable, less violent view of Chinese history that serves today's economic and political goals. Supporters say the overhaul enlivens mandatory history courses for junior and senior high school students and better prepares them for life in the real world. The old textbooks, not unlike the ruling Communist Party, changed relatively little in the last quarter-century of market-oriented economic reforms. They were glaringly out of sync with realities students face outside the classroom. But critics say the textbooks trade one political agenda for another. They do not so much rewrite history as diminish it. The one-party state, having largely abandoned its official ideology, prefers people to think more about the future than the past."

"BUSINESSES in nearly every industry were caught off guard by the Great Recession. Few leaders in business - or government, for that matter - seem to have even considered the possibility that an economic downturn of this magnitude could happen. "

A new study has revealed that whether or not a company's CEO holds a college degree from a top school has no bearing on the firm's long-term performance.

"Incensed by what it sees as a virtual pandemic of verbal vulgarity issuing from the diverse likes of Howard Stern, Bono of U2 and Robert Novak, the United States Senate is poised to consider a bill that would sharply increase the penalty for obscenity on the air. By raising the fines that would be levied against offending broadcasters some fifteenfold, to a fee of about $500,000 per crudity broadcast, and by threatening to revoke the licenses of repeat polluters, the Senate seeks to return to the public square the gentler tenor of yesteryear, when seldom were heard any scurrilous words, and famous guys were not foul mouthed all day. Yet researchers who study the evolution of language and the psychology of swearing say that they have no idea what mystic model of linguistic gentility the critics might have in mind. Cursing, they say, is a human universal. Every language, dialect or patois ever studied, living or dead, spoken by millions or by a small tribe, turns out to have its share of forbidden speech, some variant on comedian George Carlin's famous list of the seven dirty words that are not supposed to be uttered on radio or television.

"Separating anatomy from what it means to be a man or a woman, New York City is moving forward with a plan to let people alter the sex on their birth certificate even if they have not had sex-change surgery. Under the rule being considered by the city's Board of Health, which is likely to be adopted soon, people born in the city would be able to change the documented sex on their birth certificates by providing affidavits from a doctor and a mental health professional laying out why their patients should be considered members of the opposite sex, and asserting that their proposed change would be permanent. Applicants would have to have changed their name and shown that they had lived in their adopted gender for at least two years, but there would be no explicit medical requirements."

"Will you have a better life if you graduate from an elite school? Students and their parents think the answer is yes, and competition for slots at top-ranked (and costly) schools seems higher than ever. Having a big name college on your resume can impress employers, friends and the opposite sex. The Times columnist Gail Collins says this national fixation makes little sense. "We can do a great service to the youth and parents of America by telling them to stop obsessing about choosing a college," she wrote recently in The Conversation blog. "Kids, you do not need to go to a school with a name that impresses your friends. Go to a school you can afford." If enough people took her advice, the spell might be broken. In the meantime, what should sensible and ambitious students keep in mind about where they go to school?"

"Many years later, Yarbrough met with a team of psychologists who were conducting training sessions for law enforcement. They sat beside him in a darkened room and showed him a series of videotapes of people who were either lying or telling the truth. He had to say who was doing what. One tape showed people talking about their views on the death penalty and on smoking in public. Another featured a series of nurses who were all talking about a nature film they were supposedly watching, even though some of them were actually watching grisly documentary footage about burn victims and amputees. It may sound as if the tests should have been easy, because we all think we can tell whether someone is lying. But these were not the obvious fibs of a child, or the prevarications of people whose habits and tendencies we know well. These were strangers who were motivated to deceive, and the task of spotting the liars turns out to be fantastically difficult. There is just too much information--words, intonation, gestures, eyes, mouth--and it is impossible to know how the various cues should be weighted, or how to put them all together, and in any case it's all happening so quickly that you can't even follow what you think you ought to follow. The tests have been given to policemen, customs officers, judges, trial lawyers, and psychotherapists, as well as to officers from the F.B.I., the C.I.A., the D.E.A., and the Bureau of Alcohol, Tobacco, and Firearms-- people one would have thought would be good at spotting lies. On average, they score fifty per cent, which is to say that they would have done just as well if they hadn't watched the tapes at all and just guessed. But every now and again-- roughly one time in a thousand--someone scores off the charts. A Texas Ranger named David Maxwell did extremely well, for example, as did an ex-A.T.F. agent named J.J. Newberry, a few therapists, an arbitrator, a vice cop-- and John Yarbrough, which suggests that what happened in Willowbrook

"Positive psychology brings the same attention to positive emotions (happiness, pleasure, well-being) that clinical psychology has always paid to the negative ones (depression, anger, resentment). Psychoanalysis once promised to turn acute human misery into ordinary suffering; positive psychology promises to take mild human pleasure and turn it into a profound state of well-being. "Under certain circumstances, people - they're not desperate or in misery - they start to wonder what's the best thing life can offer," says Martin Seligman, one of the field's founders, who heads the Positive Psychology Center at the University of Pennsylvania. Thus positive psychology is not only about maximizing personal happiness but also about embracing civic engagement and spiritual connectedness, hope and charity. "Aristotle taught us virtue isn't virtue unless you choose it," Seligman says."

"Grisha Perelman, where are you? Three years ago, a Russian mathematician by the name of Grigory Perelman, a k a Grisha, in St. Petersburg, announced that he had solved a famous and intractable mathematical problem, known as the Poincaré conjecture, about the nature of space. After posting a few short papers on the Internet and making a whirlwind lecture tour of the United States, Dr. Perelman disappeared back into the Russian woods in the spring of 2003, leaving the world's mathematicians to pick up the pieces and decide if he was right. Now they say they have finished his work, and the evidence is circulating among scholars in the form of three book-length papers with about 1,000 pages of dense mathematics and prose between them. As a result there is a growing feeling, a cautious optimism that they have finally achieved a landmark not just of mathematics, but of human thought."

"Female physicists, astronomers and mathematicians are up against more than 2,000 years of convention that has long portrayed these fields as inherently male. Though women are no longer barred from university laboratories and scientific societies, the idea that they are innately less suited to mathematical science is deeply ingrained in our cultural genes. The problem goes back to the ancient Greeks, particularly to Pythagoras, the philosophical giant who dreamed the dream that became modern physics. Pythagoras almost certainly learned his famous theorem about right-angled triangles from the Babylonians, but we owe to him a far greater idea: "All is number," he declared, becoming the first person to say that the physical world could be described by the language of mathematics. Pythagoras also gave us the idea of the "music of the spheres," a set of mathematical relationships that would describe the structure of the universe itself. His vision would eventually give rise to the scientific revolution led by Copernicus, Kepler, Galileo and Newton. The search for a theory of everything today is the latest version of the ancient Pythagorean quest for divine "cosmic harmonies.""

"PSYCHOTHERAPY is having yet another identity crisis. It has manifested itself in two recent trends in the profession in America: the first involves trying to make therapy into more of a "hard science" by putting a new emphasis on measurable factors; the other is a growing belief among therapists that the standard practice of using talk therapy to discover traumas in a patient's past is not only unnecessary but can be injurious. That psychotherapists of various orientations find themselves under pressure to prove to themselves and to society that they are doing a hard-core science - which was a leading theme of the landmark Evolution of Psychotherapy Conference in California in December - is not really surprising. Given the prestige and trust the modern world gives to scientific standards, psychotherapists, who always have to measure themselves against the medical profession, are going to want to demonstrate that they, too, deal in the predictable; that they, too, can provide evidence for the value of what they do."

"Although Xuanyao's history teachers have taught her a lot about Japanese atrocities, she said, they are reluctant to talk about the Great Leap Forward. And they never mention the deadly Tiananmen Square protests of 1989. "Studying Chinese history is very important because it helps increase our knowledge and our patriotism," said Xuanyao, 16, dressed in purple jeans and a matching backpack. "I wasn't taught anything about Tiananmen. But what the Japanese did, particularly the Nanjing massacre, is unforgivable. Remembering this is very, very important for our national pride." China has criticized Japan in recent weeks for whitewashing its militarist history, focusing in particular on a junior high school textbook recently approved by Tokyo. A wave of anti-Japanese protests swept the world's most populous nation. A close look at China's corresponding textbook, "Chinese History -- Textbook for Junior High School," however, finds several areas where China's official history appears to have gaps of its own. "Yes, what Japan did in World War II is horrible," said Sam Crane, Asian studies professor at Williams College in Massachusetts. "But the embarrassing fact for the Communist Party, and one that is not taught in Chinese schools, is that the party itself is responsible for many more deaths of Chinese people than those caused by Japanese militarism." Historians and China scholars say an underlying theme in many Chinese textbooks is the country's victimization at the hands of foreign powers, particularly the Japanese. Although this is true, they say, China tends to underplay the long periods that it dominated its neighbors."
