Kids who work closely with parents or teachers do well, she says. "But basically letting a child educate himself, that's not going to be a good educational experience." The computer, she says, can't do it alone.

Activism in conflict zones has long brought both benefits and unforeseen consequences. It clearly helped make the crisis in Sudan’s Darfur region an international issue. But many analysts also argue that the one-sided way activists painted the conflict — highlighting the Sudanese government’s crimes against villagers while largely ignoring the atrocities committed by rebels — ultimately made it harder to negotiate an end to the crisis

some experts said Invisible Children’s campaign, while oversimplified, could help add to the international resolve to stop the killing.

Invisible Children “is essentially distilling a very complicated 26-year war into something that’s consumable and understandable by mass media.”

as a filmmaker, he said he had already received plaudits from producers in Hollywood. “They are getting in touch with the Academy Awards. They want this to be up for an Oscar.”

For 30 wonderful years, we had been unusually flush, and we got used to it, re-designing our institutions to assume unending increases in subsidized demand. This did not happen. The year it started not happening was 1975. Every year since, we tweaked our finances, hiking tuition a bit, taking in a few more students, making large lectures a little larger, hiring a few more adjuncts.

Over the decades, though, we’ve behaved like an embezzler who starts by taking only what he means to replace, but ends up extracting so much that embezzlement becomes the system. There is no longer enough income to support a full-time faculty and provide students a reasonably priced education of acceptable quality at most colleges or universities in this country.

Of the twenty million or so students in the US, only about one in ten lives on a campus. The remaining eighteen million—the ones who don’t have the grades for Swarthmore, or tens of thousands of dollars in free cash flow, or four years free of adult responsibility—are relying on education after high school not as a voyage of self-discovery but as a way to acquire training and a certificate of hireability.

Though the landscape of higher education in the U.S., spread across forty-six hundred institutions, hosts considerable variation, a few commonalities emerge: the bulk of students today are in their mid-20s or older, enrolled at a community or commuter school, and working towards a degree they will take too long to complete. One in three won’t complete, ever. Of the rest, two in three will leave in debt. The median member of this new student majority is just keeping her head above water financially. The bottom quintile is drowning.

One obvious way to improve life for the new student majority is to raise the quality of the education without raising the price. This is clearly the ideal, whose principal obstacle is not conceptual but practical: no one knows how. The value of our core product—the Bachelor’s degree—has fallen in every year since 2000, while tuition continues to increase faster than inflation.

The metaphor my colleagues often use invokes religion. In Wannabe U, the author describes the process of trying to turn UConn into a nationally competitive school as the faculty being ‘dechurched’. In this metaphor, we are a separate estate of society that has putative access to its resources, as well as the right to reject democratic oversight, managerial imperatives, and market discipline. We answer to no one but ourselves.

When the economic support from the Golden Age began to crack, we tenured faculty couldn’t be forced to share much of the pain. Our jobs were secure, so rather than forgo raises or return to our old teaching loads, we either allowed or encouraged those short-term fixes—rising tuition, larger student bodies, huge introductory lectures.

All that was minor, though, compared to our willingness to rely on contingent hires, including our own graduate students, ideal cheap labor. The proportion of part-time and non-tenure track teachers went from less than half of total faculty, before 1975, to over two-thirds now

In the same period, the proportion of jobs that might someday lead to tenure collapsed, from one in five to one in ten. The result is the bifurcation we have today: People who have tenure can’t lose it. People who don’t mostly can’t get it.

If we can’t keep raising costs for students (we can’t) and if no one is coming to save us (they aren’t), then the only remaining way to help these students is to make a cheaper version of higher education for the new student majority.

The number of high-school graduates underserved or unserved by higher education today dwarfs the number of people for whom that system works well. The reason to bet on the spread of large-scale low-cost education isn’t the increased supply of new technologies. It’s the massive demand for education, which our existing institutions are increasingly unable to handle. That demand will go somewhere.

why is not part of the answer a secondary education certification scheme that is serious and ideally nation-wide. The British GCSE/A-levels is something that seems to work. Herding the cats that would be necessary to implement something like that is, I grant, a monstrous task, but perhaps no more difficult than revising the university system. As things stand now, the lack of standards in most high schools means wasted opportunities of academic development for a very large part of our reasonably gifted teenage population. A revised university system would still leave in place the distinctly inadequate high school system we have now.

The other way to help these students would be to dramatically reduce the price or time required to get an education of acceptable quality (and for acceptable read “enabling the student to get a better job”, their commonest goal.) This is a worse option in every respect except one, which is that it may be possible.

The metaphor I have come to prefer (influenced especially by Richard Rorty) is that we in the academy are workers, and our work is to make people smarter — ourselves, our peers, our students, which is a goal that has to be constantly negotiated among various constituencies.

When the military rationale for both the GI Bill and the Soviet struggle ended, so did overall American interest in the kind of funding that drove the Golden Age. There is not now and has never been a broad commitment to higher education as a social good in this country

ow you can say — and many of my colleagues do — that this is all just a matter of getting state governments to take on different concerns or convictions, or getting a more nationalized educational system. That was the song my parents, both educators, sang, and the song I grew up singing. But the period when the states really drove funding up lasted just 15 years — 1960 to 1975 — and has been in decline for 40 years since.

I can — barely — imagine some states increasing some subsidies to some campuses at a rate faster than inflation. Some of the schools in California, Virginia, Massachusetts, and Michigan are candidates for this. I cannot, however, imagine my tenured colleagues tolerating the situation that makes higher education broadly affordable in social democracies, which would require us earning less while teaching more.

I am done, in other words, thinking of myself and my peers on faculty as blameless, and I am done imagining that 40 years of evidence from the behavior of democratically elected legislatures is some sort of readily reversible blip. I do not believe that the caste system that has established itself at elite institutions can be funded at the rate which we insist we need, and I do not believe that we will willingly see any of our own benefits reduced to help our junior colleagues or our students.

Students feel compelled to acquire credentialing as a means of improving their economic positions. Unfortunately, along the way, “professional” training has taken precedence over education. The two have become conflated in the public mind.

Today it is not only that the PhD:s are abundant but also that in many areas peak knowledge is short lived. You might be competent when you graduate but five years later that competence is of yesteryear and the ones with the newest knowledge kick you out just like you kicked someone else out five years ago. We need a base to stand on but then we need to go in and out of education during our whole lives to keep up with development. This puts a strain on each end everyone of us as individuals but it also calls for a whole new role for academia

Change the game and lower the transaction costs: Instead of treating students as backseat passengers in a higher educational vehicle that’s geared towards the transmission of self-contained content, i.e., content produced by professors for the self-serving purpose of publication–put steering wheels in the hands of students, take them out on road trips, negotiate real problems–and they will become self-educating

Note that having a college degree only retains value right now because there isn’t a better (more predictive, and trusted) credential to be had for people who are seeking jobs.

the online versions of education have reduced the college experience down to what’s easy to implement and easy to measure: receiving lectures, and activities of the quiz-and-test variety. It’s not clear that the value of the traditional old-school college experience (and it’s accompanying degree) were the result of those particular aspects of the experience. Granting degrees based only on coursework runs the risk of diluting the perceived value of the degree.

Adam Smith argued forcefully that we would do better to trust in the pursuit of self-interest than in the good intentions of those who pursue the general interest. If everyone looked out for just himself, we would reach an equilibrium that was not just comfortable but also productive, in which the economy was fully efficient. To the morally uninspired, it’s an appealing idea: selfishness as the ultimate form of selflessness. (Elsewhere, in particular in his “Theory of Moral Sentiments,” Smith took a much more balanced view, though most of his latter-day adherents have not followed suit.)

This cascade of trust destruction was unrelenting. One of the reasons that the bubble’s bursting in 2007 led to such an enormous crisis was that no bank could trust another. Each bank knew the shenanigans it had been engaged in — the movement of liabilities off its balance sheets, the predatory and reckless lending — and so knew that it could not trust any other bank

Things didn’t turn out well for our economy or our society. As millions lost their homes during and after the crisis, median wealth declined nearly 40 percent in three years. Banks would have done badly, too, were it not for the Bush-Obama mega-bailouts.

bankers used their political influence to eviscerate regulations and install regulators who didn’t believe in them. Officials and academics assured lawmakers and the public that banks could self-regulate. But it all turned out to be a scam. We had created a system of rewards that encouraged shortsighted behavior and excessive risk-taking. In fact, we had entered an era in which moral values were given short shrift and trust itself was discounted.

THE banking industry is only one example of what amounts to a broad agenda, promoted by some politicians and theoreticians on the right, to undermine the role of trust in our economy. This movement promotes policies based on the view that trust should never be relied on as motivation, for any kind of behavior, in any context. Incentives, in this scheme, are all that matter.

So C.E.O.’s must be given stock options to induce them to work hard. I find this puzzling: If a firm pays someone $10 million to run a company, he should give his all to ensure its success. He shouldn’t do so only if he is promised a big chunk of any increase in the company’s stock market value

Of course, incentives are an important component of human behavior. But the incentive movement has made them into a sort of religion, blind to all the other factors — social ties, moral impulses, compassion — that influence our conduct.

Similarly, teachers must be given incentive pay to induce them to exert themselves. But teachers already work hard for low wages because they are dedicated to improving the lives of their students. Do we really believe that giving them $50 more, or even $500 more, as incentive pay will induce them to work harder? What we should do is increase teacher salaries generally because we recognize the value of their contributions and trust in their professionalism. According to the advocates of an incentive-based culture, though, this would be akin to giving something for nothing.

This is not just a coldhearted vision of human nature. It is also implausible. It is simply impossible to pay for trust every time it is required. Without trust, life would be absurdly expensive; good information would be nearly unobtainable; fraud would be even more rampant than it is; and transaction and litigation costs would soar.

When 1 percent of the population takes home more than 22 percent of the country’s income — and 95 percent of the increase in income in the post-crisis recovery — some pretty basic things are at stake. Reasonable people, even those ignorant of the maze of unfair policies that created this reality, can look at this absurd distribution and be pretty certain that the game is rigged.

Trust between individuals is usually reciprocal. But if I think that you are cheating me, it is more likely that I will retaliate, and try to cheat you. (These notions have been well developed in a branch of economics called the “theory of repeated games.”) When Americans see a tax system that taxes the wealthiest at a fraction of what they pay, they feel that they are fools to play along.

a deeper rot takes hold: Attitudes and norms begin to change. When no one is trustworthy, it will be only fools who trust. The concept of fairness itself is eroded. A study published last year by the National Academy of Sciences suggests that the upper classes are more likely to engage in what has traditionally been considered unethical behavior. Perhaps this is the only way for some to reconcile their worldview with their outlandish financial success, often achieved through actions that reveal a kind of moral deprivation.

As always, it is the poor and the unconnected who suffer most from this, and who are the most repeatedly deceived. Nowhere was this more evident than in the foreclosure crisis.

The banks figured out how to get court affidavits signed by the thousands (in what came to be called robo-signing), certifying that they had examined their records and that these particular individuals owed money — and so should be booted out of their homes. The banks were lying on a grand scale, but they knew that if they didn’t get caught, they would walk off with huge profits, their officials’ pockets stuffed with bonuses. And if they did get caught, their shareholders would be left paying the tab

But perhaps even more than opportunity, Americans cherish equality before the law. Here, inequality has infected the heart of our ideals.

I suspect there is only one way to really get trust back. We need to pass strong regulations, embodying norms of good behavior, and appoint bold regulators to enforce them.

Nicholas Carr, author of “The Shallows: What the Internet Is Doing to Our Brains,” said the speech was part of “a resurgence of millenarian thinking in Silicon Valley.” The dream of an extra-societal utopia grows in part out of a “naïve libertarianism” ascendant in the Valley, and in part out of older American cultist traditions dating as far back as the Pilgrims, he said.

Mr. Srinivasan cast entrepreneurs as a persecuted people who must flee to survive. The Valley, he argued, is taking over the rest of America’s traditional raisons d’être. Netflix and iTunes challenge Hollywood. Twitter and blogs challenge New York media. The Khan Academy and Coursera challenge Boston’s universities. Uber and Airbnb challenge the regulatory state personified by Washington.

His proposed solution is seceding from the society before the “backlash” against the Valley grows.

Some of the biggest names in the Valley have variously proposed building a Mars colony, an unregulated zone of experimentation on Earth or floating libertarian islands at sea.

“The best part is this,” he said. “The people who think this is weird, the people who sneer at the frontier, who hate technology — they won’t follow you out there.”

American conservatism has always been different than the conservatism found on continental Europe and elsewhere. There it was based on blood and soil, here on promise.

American free market and religious conservatives have traditionally embraced a style of nationalism that is hopeful and future minded. From Lincoln to Reagan to Bush, the market has been embraced for being dynamic and progressive. The major faiths uplift in part because they are eschatological — they look forward to a glorious future.

This pessimism isn’t justified by the facts. As a definitive report from the National Academies of Sciences, Engineering and Medicine recently found, today’s immigrants are assimilating as fast as previous ones. They are learning English. They are healthier than native-born Americans. Immigrant men age 18 to 39 are incarcerated at roughly one-fourth the rate of American men.

“It is all an act. It is a show,” said Alaa Hamam, 38, a Cairo University employee joining a protest in Tahrir Square, the symbolic heart of the uprising. “It is a provocation.”

Against an opaque backdrop of military rule, in which the generals, prosecutors and judges were all appointed by Mr. Mubarak, the degree of judicial independence is impossible to know. Demonstrators slammed the decision as a ruse designed to placate them without holding anyone accountable for the violence or corruption of the old government.

Both sons stood in front of their father to try to shield him from the cameras. Alaa Mubarak appeared to recite verses from the Koran as the verdict was read. And after the ruling, both sons had tears in their eyes. They remain in jail while they face charges in an unrelated stock-manipulation case announced last week.

He called Mr. Mubarak’s tenure “30 years of intense darkness — black, black, black, the blackness of a chilly winter night.”

As Mr. Mubarak’s last prime minister, Mr. Shafik presided over the cabinet when the police failed to protect unarmed protesters in Tahrir Square from a deadly assault by a mob of Mubarak supporters known as the “battle of the camels.”

“The verdict means that the head of the regime and the minister of interior are the only ones who have fallen, but the rest of the entire regime remains,” the Brotherhood, Egypt’s largest Islamist group, said in a statement.” It added, “The Egyptian people have to sense the great danger that threatens their revolution and their hopes, and wastes the blood of the martyrs and the sacrifices of their children.”

In the parking lot outside the makeshift courthouse in a police academy, some initially celebrated the verdict. “I am so happy — this is the greatest happiness I have ever felt,” said Rada Mohamed Mabrouk, a 60-year-old retiree. “The martyrs are all of our children.”

The judge dismissed the corruption charges against Mr. Mubarak and his sons on the grounds that a statute of limitations had expired since the three Mubaraks were said to have received the vacation homes. Prosecutors had evidently hoped to date the crime from the subsequent favors Mr. Mubarak did for Mr. Salem. It was unclear why the judge had not raised the statute of limitations issue earlier.

First, there’s ideology.  Since the late nineteenth century most intellectuals have identified progress with the advance of the bureaucratic, redistributionist and administrative state.

Most American intellectuals today are still shaped by this worldview and genuinely cannot imagine an alternative vision of progress.  It is extremely difficult for such people to understand the economic forces that are making this model unsustainable and to see why so many Americans are in rebellion against this kind of state and society – but if our society is going to develop we have to move beyond the ideas and the institutions of twentieth century progressivism.  The promises of the administrative state can no longer be kept and its premises no longer hold.

This doesn’t mean that government becomes insignificant.  The state will survive and as social life becomes more complex it will inevitably acquire new responsibilities – but it will look and act less like the administrative, bureaucratic entity of the past. 

Second, there are the related questions of interest and class.  Most intellectuals today still live in a guild economy.  The learned professions – lawyers, doctors, university professors, the clergy of most mainline denominations, and (aspirationally anyway) school teachers and journalists – are organized in modern day versions of the medieval guilds.  Membership in the guilds is restricted, and the self-regulated guilds do their best to uphold an ideal of service and fairness and also to defend the economic interests of the members.

Just as the industrial revolution broke up the manufacturing guilds, the information revolution today is breaking up the knowledge guilds. 

Ultimately one suspects that services once reserved for elites will be available for the masses, just as the industrial revolution enabled mass ownership of goods that had once been the preserve of small elites.  The effect will not only be to raise living standards for most people by improving their access to useful services.  It will also be to transfer power and authority from the provider of such services to the consumer.

Third, there’s training.  America today has many technical intellectuals – people like doctors, engineers, and others who are able to carry out complex tasks – and we are extraordinarily rich in specialist intellectuals who have a deep knowledge of a particular subject. 

We are much less effective at teaching and supporting people who are able to master the essentials of many complex subjects, integrate the insights from this kind of study into a coherent social or political vision, and communicate what they have learned to a broad general lay audience.  The more complex a society and the more rapidly it is changing, the more need it has for multi-disciplinary, synthesizing intellectuals who are focused on communicating serious ideas to a large audience.

In most of our learned professions and knowledge guilds today, promotion is linked to the needs and aspirations of the guild rather than to society at large.  Promotion in the academy is almost universally linked to the production of ever more specialized, theory-rich (and, outside the natural sciences, too often application-poor) texts, pulling the discourse in one discipline after another into increasingly self-referential black holes.  We suffer from ‘runaway guilds’: costs skyrocket in medicine, the civil service, education and the law in part because the imperatives of the guilds and the interests of their members too often triumph over the needs and interests of the wider society.

Right now, too many intellectuals try to turn this into a left/right debate rather than one about the past and the future.

The technique holds the power to repair or enhance any human gene. “It raises the most fundamental of issues about how we are going to view our humanity in the future and whether we are going to take the dramatic step of modifying our own germline and in a sense take control of our genetic destiny, which raises enormous peril for humanity,”

The paper’s authors, however, are concerned about countries that have less regulation in science. They urge that “scientists should avoid even attempting, in lax jurisdictions, germline genome modification for clinical application in humans” until the full implications “are discussed among scientific and governmental organizations.”

Though such a moratorium would not be legally enforceable and might seem unlikely to exert global influence, there is a precedent. In 1975, scientists worldwide were asked to refrain from using a method for manipulating genes, the recombinant DNA technique, until rules had been established.

Though highly efficient, the technique occasionally cuts the genome at unintended sites. The issue of how much mistargeting could be tolerated in a clinical setting is one that Dr. Doudna’s group wants to see thoroughly explored before any human genome is edited.

“We worry about people making changes without the knowledge of what those changes mean in terms of the overall genome,” Dr. Baltimore said. “I personally think we are just not smart enough — and won’t be for a very long time — to feel comfortable about the consequences of changing heredity, even in a single individual.”

Many ethicists have accepted the idea of gene therapy, changes that die with the patient, but draw a clear line at altering the germline, since these will extend to future generations. The British Parliament in February approved the transfer of mitochondria, small DNA-containing organelles, to human eggs whose own mitochondria are defective. But that technique is less far-reaching because no genes are edited.

There are two broad schools of thought on modifying the human germline, said R. Alta Charo, a bioethicist at the University of Wisconsin and a member of the Doudna group. One is pragmatic and seeks to balance benefit and risk. The other “sets up inherent limits on how much humankind should alter nature,” she said. Some Christian doctrines oppose the idea of playing God, whereas in Judaism and Islam there is the notion “that humankind is supposed to improve the world.” She described herself as more of a pragmatist, saying, “I would try to regulate such things rather than shut a new technology down at its beginning.

The Doudna group calls for public discussion, but is also working to develop some more formal process, such as an international meeting convened by the National Academy of Sciences, to establish guidelines for human use of the genome-editing technique.“We need some principled agreement that we want to enhance humans in this way or we don’t,” Dr. Jaenisch said. “You have to have this discussion because people are gearing up to do this.”

what if the template for football’s future is not the fate of boxing but rather that of the tobacco industry?

About 18 percent of American adults now smoke — fewer than one in five. Tobacco’s shift from integral part of American life to its fringes took about half a century.

The proposed settlement has been almost universally perceived as a victory for the league. With it, the N.F.L. bought itself — cheaply, considering its $9 billion in annual revenue — a degree of short-term business certainty. It initially agreed to set aside $765 million for brain-injured players or, in the case of those who died, their heirs. After Brody, who presides over the suit, said the fund might not cover payments to all those who qualified, the league agreed to a deal with no upper limit on its liability. But because of how the settlement delineates which afflictions qualify for financial compensation and caps the awards on what can go out to individuals, the N.F.L.'s total liability, paid out over decades, may not rise much beyond $1 billion

That’s nothing for an entity as rich as the N.F.L. Goodell, the league’s commissioner, made $44 million last year — or nearly nine times the maximum payment for the most severely brain-damaged N.F.L. retiree.

But the settlement does get money into the hands of some players who need it desperately, perhaps soon. It also sets aside $112 million for lawyers, who, if the case had gone to trial, might have waited years to be paid.

It is shortsighted, however, to assume that the N.F.L. and its owners will emerge from the settlement unscathed or that the league’s economic and cultural status are not under threat. Now that the N.F.L. has acknowledged that its product comes with dire health consequences, the sport, below the professional level, faces legal and regulatory challenges that will most likely intensify in the coming years.

It’s possible that the very thing meant to protect players — new protocols that define how they should be evaluated for a possible brain injury, and how long they should be kept out of play if one is diagnosed or suspected — will actually put school districts, administrators and coaches at more legal risk. Now that they have, in a sense, been forewarned, what happens if they don’t follow the protocols or don’t have certified athletic trainers on staff or coaches smart enough to deal with possible concussions while they are also deciding on the right third-down play?

What’s more, insurers may in time deem the sport too risky. Health insurers might treat it as a costly risk factor like smoking or a bad driving record. As football becomes more and more regulated, many districts may reasonably conclude that it’s more than they can handle.

“but you have to ask how the concussions issue changes the landscape from a law-enforcement perspective. I think it has to over time, because we now know that players are suffering repeated insults to the parts of the brain that cause changes in behavior.” Rates of smoking plunged and the industry declined because tobacco use could not be made safe. The N.F.L. may be at a similar juncture now. It has instituted rules changes to make its own games less violent and is funding and promulgating supposedly less dangerous ways to play at the youth level. But there is no assurance that any of it will make football any more healthful than low-tar cigarettes made smoking. The burden will fall on the N.F.L. to litigate the concussion issue in public and prove that its sport does not rob participants of their consciousness.

Between 2010 and 2012, Pop Warner, the nation’s largest youth-football program, experienced a 10 percent drop in participation after years of steady growth. It attributed the decline to concerns over concussions. There’s no reason to think its numbers won’t continue to fall.

Instead of increasing public funds for higher education, it suggests taking financial assistance that now goes to higher-income families and redirecting it to the neediest.

We now have robust results showing that vocational programs like career academies help disadvantaged young people get jobs and raise their marriage rates. Parent-coaching programs improve disadvantaged children’s outcomes so much that they save public money.

The sad truth is that neither party has done enough to address the shame of deep-rooted poverty in America. So let’s hope for a real contest in this area, because everybody loses — above all, America’s neediest — when most of the time one party doesn’t even bother to show up.

At this point, Rome had somewhere between 1 million and 2 million residents. For perspective, 2 million residents would make Rome bigger than every American city today except for New York, LA, Chicago, and Houston. And this was 1700 years ago!

nterestingly, Rome itself isn't built near potable water. According to Frischer, the Romans managed to support a modern-size metropolis using an absolutely massive system of aqueducts — literally "roads for water" that brought in clean stuff from nearby mountains and rivers.

The video shows the Colosseum as it would have looked at its full size, which is truly colossal. We also learn that the Colosseum wasn't what Romans called it (that name dates to later, in the Middle Ages). It was actually called the Flavian Amphitheater, built by the Emperor Vespasian in a bid to gain popularity after his mad predecessor, Nero, allowed huge portions of the city to burn down.

“It is wonderful. I had been living a double life, wearing a turban only at home,” he said. “My two worlds have finally come back together.”

It is the first time in decades that the military has granted a religious accommodation for a beard to an active-duty combat soldier — a move that observers say could open the door for Muslims and other troops seeking to display their faith. But it is only temporary, lasting for a month while the Army decides whether to give permanent status to Captain Singh’s exception.

“This is a precedent-setting case,” said Eric Baxter, senior counsel at the Becket Fund, a nonprofit public interest law firm that specializes in religious liberty. “A beard is a beard is a beard. If you let one religious individual grow it, you will need to do it for all religions.”

The United States military has become increasingly inclusive, allowing gay men and lesbians to serve openly, and women to serve in combat roles. But it has held a stiff line on uniforms and grooming standards. Though over the centuries these standards have included powdered wigs and Civil War mutton chops, in recent decades the military has insisted on men being clean-shaven with hair shorn high and tight.

The general added that any break from uniformity could erode esprit de corps and “damage the esteem and credibility” of the entire officer corps.

This summer, a United States District Court judge rejected the safety argument, noting that more than 100,000 troops have been allowed to grow beards for medical reasons such as acne and sensitive skin. The judge ruled the Army’s denial was illegal. But the decision applied only to students enrolling in R.O.T.C., leaving the larger question of beards for active-duty troops untouched.

Bearded Sikhs fought in the United States Army in World War II and Vietnam. Today, Sikhs in full religious garb serve in militaries around the world.

“It was a way to identify the Sikhs, who became a sort of military order that stood up against oppression,” said Kamaljeet Singh Kalsi, a doctor who is a major in the Army Reserve.

The Army has used a procedural Catch-22 to sidestep the question of

whether regulations protecting religious freedom allow for beards. For years, it denied requests from incoming recruits, saying accommodations could be granted only after recruits had formally joined. Recruits could not formally join without conforming to grooming standards. In short, to get permission to not shave, you had to shave.

“A true Sikh is supposed to stand out, so he can defend those who cannot defend themselves,” he said. “I see that very much in line with the Army values.”

He has made his own camouflage turbans to wear to his first day of work at Fort Belvoir, Va., on Monday.“I hope this shows others that they can both serve their faith and serve their country,” he said.

under Otto von Bismarck and then the kaiser. Numbers alone tell a story: In 1870, as Bismarck unified Germany, Kiel had around 30,000 inhabitants.

Always calm, she brooked little criticism and brushed aside anti-German sentiment as she pushed to impose austerity on supposedly profligate European neighbors.

When he learned of the assassination in Sarajevo of Archduke Franz Ferdinand, the heir to the Hapsburg Empire, he hastened to Berlin.

Britain and France were alarmed by Wilhelm’s ambition. Britain’s determination to keep its navy supreme only heightened German anxieties, already running high because the kaiser felt beleaguered on two fronts.

Wilhelm poured torrents of money into the German Navy. In 1906, Britain’s Royal Navy took delivery of H.M.S. Dreadnought, with its groundbreaking armament of big guns. Wilhelm

Naval historians, however, tend to accord more significance to Germany’s U-boats, which were responsible for the sinking of the Lusitania in 1915, for instance, eventually helping to draw the United States into Europe’s Great War.

Wilhelm’s proud Naval Academy, for instance, is now the parliamentary seat of Schleswig-Holstein, the state of which Kiel is the capital.

On campuses, activists interpret ordinary interactions as “microaggressions” and set up “safe spaces” to protect students from certain forms of speech. And presidential candidates on both the left and the right routinely motivate supporters by declaring that they are under attack by immigrants or wealthy people.

victimhood makes it more and more difficult for us to resolve political and social conflicts. The culture feeds a mentality that crowds out a necessary give and take — the very concept of good-faith disagreement — turning every policy difference into a pitched battle between good (us) and evil (them).

Consider a 2014 study in the Proceedings of the National Academy of Sciences, which examined why opposing groups, including Democrats and Republicans, found compromise so difficult. The researchers concluded that there was a widespread political “motive attribution asymmetry,” in which both sides attributed their own group’s aggressive behavior to love, but the opposite side’s to hatred. Today, millions of Americans believe that their side is basically benevolent while the other side is evil and out to get them.

Members of one group were prompted to write a short essay about a time when they felt bored; the other to write about “a time when your life seemed unfair. Perhaps you felt wronged or slighted by someone.” After writing the essay, the participants were interviewed and asked if they wanted to help the scholars in a simple, easy task. The results were stark. Those who wrote the essays about being wronged were 26 percent less likely to help the researchers, and were rated by the researchers as feeling 13 percent more entitled.

In a separate experiment, the researchers found that members of the unfairness group were 11 percent more likely to express selfish attitudes. In a comical and telling aside, the researchers noted that the victims were more likely than the nonvictims to leave trash behind on the desks and to steal the experimenters’ pens.

Does this mean that we should reject all claims that people are victims? Of course not. Some people are indeed victims in America — of crime, discrimination or deprivation. They deserve our empathy and require justice.

The problem is that the line is fuzzy between fighting for victimized people and promoting a victimhood culture.

look at the role of free speech in the debate. Victims and their advocates always rely on free speech and open dialogue to articulate unpopular truths. They rely on free speech to assert their right to speak. Victimhood culture, by contrast, generally seeks to restrict expression in order to protect the sensibilities of its advocates

look at a movement’s leadership. The fight for victims is led by aspirational leaders who challenge us to cultivate higher values. They insist that everyone is capable of — and has a right to — earned success. They articulate visions of human dignity. But the organizations and people who ascend in a victimhood culture are very different. Some set themselves up as saviors; others focus on a common enemy. In all cases, they treat people less as individuals and more as aggrieved masses.

She went on to say that the prestigious and exclusive Penn Law Review had a “diversity mandate,” and that some black students face an “uphill battle” because they aren’t properly matched to the high-level school. “We’re not saying they shouldn’t go to college – we’re not saying that,” she said. “I mean, some of them shouldn’t.”

Wax would not talk with the Forward on the record about the controversy. But she did write an op-ed in the Wall Street Journal last week pointing out that Ruger had not actually released data that would have proved her right or wrong – which the petition itself also asked for – and called on him to do so.

She also claimed in a return appearance to Bloggingheads last week that she was a mentor to black students and had never received a bias complaint until last year, and that Penn’s blind grading process prevents her from knowing which grade she is giving to which students until the semester ends.

She also admitted that she did not have data that could prove her original statement about class rank correct.

In an 2015 article explaining her opposition to affirmative action programs, Wax described her childhood as “part of a close-knit, observant, conservative Jewish family in a predominantly Catholic town….Although it was common in our culture to complain a lot — about friends, relatives, business partners, bad luck, and the general cluelessness of non-Jews—we were not permitted to complain that anti-Semitism and discrimination were standing in our way. We knew discrimination was out there, but the discussion was limited to anti-Semitism as a general social problem rather than as a stumbling block in individual lives.”

Her 2009 book “Race, Wrongs and Remedies” argued that cultural-behavioral issues, not racism, are the most important factors preventing African-American progress. Such statements have garnered criticism from black Penn students as far back as 2005.

Nonetheless, according to RateMyProfessors.com, Wax has received mostly high marks from her students in recent years, though one commenter described her as someone who is “obsessed with her own victimization at the hands of forces she believes deserve blame for being victims themselves” but is nonetheless a “decent instructor when she can just stick to the course content.”

But for Penn students, especially students of color, the decision to remove Wax from her introductory class was the right one. “It’s been incredible to see how black students and alumni came together, grappled with how to handle this, and moved to create a change, and I hope that it continues,” the president of Penn’s Black Law Students Association, Nick Hall, told Philly.com.

Wax, for her part, sees her experience as part of an ominous trend, which could especially affect Jewish students. “Jews have been harmed by the threats to freedom of opinion and debate, the punishments for candor, and the decline in rigorous standards in the academy that have accompanied progressive hegemony, which insists upon the sacrosanct status of affirmative action and other policies favored by the left,” Wax wrote in an email to the Forward. She added that such pressures were especially powerful on female students. “Things were so much better in the 1970s, when I was a young women undergraduate at Yale. I am grateful to have come of age during that period. I wouldn’t want to be an undergraduate at an elite college today.”

hat urgency is at odds with the stance of the Trump administration, which has rolled back several Obama-era environmental regulations and incentivized the production of fossil fuels. Trump also has said he plans to withdraw the nation from the Paris climate accord and questioned the science of climate change just last month, saying on CBS’s “60 Minutes” that “I don’t know that it’s man-made” and that the warming trend “could very well go back.”

“This report draws a direct connection between the warming atmosphere and the resulting changes that affect Americans' lives, communities, and livelihoods, now and in the future,” the document reads, concluding that “the evidence of human-caused climate change is overwhelming and continues to strengthen, that the impacts of climate change are intensifying across the country, and that climate-related threats to Americans' physical, social, and economic well-being are rising.

The report finds that the continental United States already is 1.8 degrees Fahrenheit warmer than it was 100 years ago, surrounded by seas that are on average nine inches higher and being racked by far worse heat waves than the nation experienced only 50 years ago. But those figures offer only the prelude to even more potentially severe impacts. The report suggests that by 2050, the country could see as much as 2.3 additional degrees of warming in the continental United States. By that same year, in a high-end global-warming scenario, coral reefs in Hawaii and the U.S. Pacific territories could be bleaching every single year — conditions in which their survival would be in severe doubt. A record-warm year like 2016 would become routine.

In another major step, the authors of the new report have begun to put dollar signs next to projected climate damage, specifically within the United States. In a worst-case climate-change scenario, the document finds, labor-related losses by the year 2090 as a result of extreme heat — the sort that makes it difficult to work outdoors or seriously lowers productivity — could amount to an estimated $155 billion annually. Deaths from temperature extremes could take an economic toll of $141 billion per year in the same year, while coastal property damage could total $118 billion yearly, researchers found

Of course, mitigating climate change would also mitigate this damage, by as much as 58 percent in the case of high-temperature related deaths, the report finds.

The categorical tone of the new assessments reflects scientists' growing confidence in the ability to detect the role of a changing climate in individual extreme events, such as heat waves and droughts. At the same time, increasingly sophisticated computer simulations now allow them to project future changes in highly specific regions of the country

The Second State of the Carbon Cycle Report, which examines all of North America (not just the United States), finds that over a decade, greenhouse-gas emissions from fossil fuels declined by 1 percent per year. The result is that while North America emitted 24 percent of the world’s emissions in 2004, that was down to 17 percent in 2013. This occurred in part thanks to improvements in vehicle fuel efficiency, the growth of renewable energy and the swapping of coal-burning for natural gas.

“For the globe, we’re still going up, but regionally, there have been these changes in how humans have been acting that have caused our emissions to go down,” said Ted Schuur, a Northern Arizona University expert on permafrost carbon

The report concludes that it appears possible to for economies to grow — at least in the United States, Mexico and Canada — without increasing overall emissions of greenhouse gases. That would be an important signal for the ability of the world to slow climate change over the course of the century

“It’s not a threat to their own economic well-being; it’s a threat to their group’s dominance in our country over all.”

Last year, a Public Religion Research Institute survey of more than 3,000 people also found that Mr. Trump’s appeal could better be explained by a fear of cultural displacement.

she analyzed survey data from a nationally representative group of about 1,200 voters polled in 2012 and 2016.

Dr. Mutz’s statistical analysis focused on those who bucked the trend, switching their support to the Republican candidate, Mr. Trump, in 2016.

Dr. Mutz also analyzed a separate survey, conducted in 2016 by the National Opinion Research Center at the University of Chicago. It showed that anxieties about retirement, education and medical bills also had little impact on whether a person supported Mr. Trump.

Losing a job or income between 2012 and 2016 did not make a person any more likely to support Mr. Trump

A person’s opinion on how trade affected personal finances had little bearing on political preferences

uation had worsened

Neither did unemployment or the density of manufacturing jobs in one’s area.

“It wasn’t people in those areas that were switching, those folks were already voting Republican,” Dr. Mutz said.

Even before conducting her analysis, Dr. Mutz noted two reasons for skepticism of the economic anxiety, or “left behind,” theory. First, the economy was improving before the 2016 presidential campaign. Second, while research has suggested that voters are swayed by the economy, there is little evidence that their own financial situation similarly influences their choices at the ballot box.

Last year’s Public Religion Research Institute report went even further, finding a link, albeit a weak one, between poor white, working-class Americans and support for Hillary Clinton.

While economic anxiety did not explain Mr. Trump’s appeal, Dr. Mutz found reason instead to credit those whose thinking changed in ways that reflected a growing sense of racial or global threat.

the findings revealed a fear that American global dominance was in danger, a belief that benefited Mr. Trump and the Republican Party.

“The shift toward an antitrade stance was a particularly effective strategy for capitalizing on a public experiencing status threat due to race as well as globalization,” Dr. Mutz wrote in the study.

“It used to be a pretty good deal to be a white, Christian male in America, but things have changed and I think they do feel threatened,

The other surveys supported the cultural anxiety explanation, too.

For example, Trump support was linked to a belief that high-status groups, such as whites, Christians or men, faced more discrimination than low-status groups, like minorities, Muslims or women

If wrong, the prevailing economic theory lends unfounded virtue to his victory, crediting it to the disaffected masses

More important, she said, it would teach the wrong lesson to elected officials, who often look to voting patterns in enacting new policy.

Mr. Obama’s reading lists are peppered with science and science fiction titles such as Elizabeth Kolbert’s “The Sixth Extinction,” Atul Gawande’s “Being Mortal” and Liu Cixin’s “The Three-Body Problem.”

But Mr. Obama’s grasp of real science before becoming president was sketchy. He once admitted to a room full of scientists to not doing “well enough in chemistry or physics to impress you much on those topics.” And some scientists who met Mr. Obama before the presidency said they were not wowed by his grasp of their fields.

“He’s an academic, he’s one of us,” Dr. Varmus said. “He’s a rational, levelheaded guy who makes decisions based on the evidence. Now, that might actually be a deficiency as a politician.”
