the form of definitive randomized controlled trials, the so-called gold standard for scientific research.

Yet the notion has taken hold that such expertise is fatally subjective and that only randomized controlled trials provide real knowledge.

the evidence-based medicine movement, which placed such trials atop a hierarchy of scientific methods, with expert opinion situated at the bottom.

While many American parents are angry about the Common Core educational standards and related student assessments in math and English, less attention is being paid to the federally driven green Common Core that is now being rolled out across the country. Under the guise of the first new K-12 science curriculum to be introduced in 15 years, the real goal seems to be to expose students to politically correct climate-change orthodoxy during their formative learning years.

The standards were designed to provide students with an internationally benchmarked science education.

From the council’s perspective, the science of climate change has already been settled. Not surprisingly, global climate change is one of the disciplinary core ideas embedded in the Next Generation of Science Standards, making it required learning for students in grade, middle and high school.

THIS is a strange moment for sex in America. We’ve detached it from pregnancy, matrimony and, in some circles, romance. At least, we no longer assume that intercourse signals the start of a relationship.

But the more casual sex becomes, the more we demand that our institutions and government police the line between what’s consensual and what isn’t. And we wonder how to define rape. Is it a violent assault or a violation of personal autonomy? Is a person guilty of sexual misconduct if he fails to get a clear “yes” through every step of seduction and consummation?

According to the doctrine of affirmative consent — the “yes means yes” rule — the answer is, well, yes, he is.

America’s overall performance in K-12 education remains stubbornly mediocre.

The debate over school reform has become a false polarization

teaching is a complex activity that is hard to direct and improve from afar. The factory model is appropriate to simple work that is easy to standardize; it is ill suited to disciplines like teaching that require considerable skill and discretion.

He and his team have shown, again and again, and in many different ways, that much of what biomedical researchers conclude in published studies—conclusions that doctors keep in mind when they prescribe antibiotics or blood-pressure medication, or when they advise us to consume more fiber or less meat, or when they recommend surgery for heart disease or back pain—is misleading, exaggerated, and often flat-out wrong. He charges that as much as 90 percent of the published medical information that doctors rely on is flawed. His work has been widely accepted by the medical community

for all his influence, he worries that the field of medical research is so pervasively flawed, and so riddled with conflicts of interest, that it might be chronically resistant to change—or even to publicly admitting that there’s a problem

he discovered that the range of errors being committed was astonishing: from what questions researchers posed, to how they set up the studies, to which patients they recruited for the studies, to which measurements they took, to how they analyzed the data, to how they presented their results, to how particular studies came to be published in medical journals

meaning” has become the stand-in concept for everything the soul yearns for and seeks. It is one of the few phrases acceptable in modern parlance to describe a fundamentally spiritual need.

what do we mean when we use the word meaning?

as commonly used today, the word is flabby and vacuous, the product of a culture that has grown inarticulate about inner life.

Nearly everybody cheats, but usually only a little

They cheated a little, but not a lot.

That’s because most of us think we are pretty wonderful. We can cheat a little and still keep that “good person” identity. Most people won’t cheat so much that it makes it harder to feel good about themselves.

scholars covet thy neighbor's data. They're attracted to the very large and often fascinating data sets that private companies have developed.

It's the companies that own and manage this data. The only standards we know they have to follow are in the terms-of-service that users accept to create an account, and the law as it stands in different countries.

the "sexiness" of the Facebook data that led Cornell University and the Proceedings of the National Academy of Sciences (PNAS) into an ethically dubious arrangement, where, for example, Facebook's unreadable 9,000-word terms-of-service are said to be good enough to meet the standard for "informed consent."

Dr. Heuer, born in Bad Boll in southern Germany in 1948, has spent his career in the trenches of particle physics, in which scientists emulate 3-year-olds by smashing bits of matter together to see what comes out.

He had an opportunity to put that philosophy to the test early in his term at CERN, when physicists reported in a seminar there that they had measured subatomic particles known as neutrinos streaming from Geneva to their detector in Italy faster than the speed of light, contrary to the laws of physics then known.

The neutrino controversy helped set a sort of dubious stage for the main event in particle physics so far this century: the Higgs boson.

More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.

Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"

Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.

What is wrong with the economies of the West—and with economics?

With little or no effective policy initiative giving a lift to the less advantaged, the jarring market forces of the past four decades—mainly the slowdowns in productivity that have spread over the West and, of course, globalization, which has moved much low-wage manufacturing to Asia—have proceeded, unopposed, to drag down both employment and wage rates at the low end. The setback has cost the less advantaged not only a loss of income but also a loss of what economists call inclusion—access to jobs offering work and pay that provide self-respect.

The classical idea of political economy has been to let wage rates sink to whatever level the market takes them, and then provide everyone with the “safety net” of a “negative income tax,” unemployment insurance, and free food, shelter, clothing, and medical care

Now imagine that something even more fundamental than electricity or money is at risk: a tool we have relied on since the dawn of human history, enabling the very foundations of civilisation to be laid

I’m talking about our ability to communicate – to put our thoughts into words, and to use those words to forge bonds, to deliver vital information, to learn from our mistakes and build on the work done by others.

“Their language is deteriorating. They are lowering the bar. Our language is flying off at all tangents, without the anchor of a solid foundation.

A mini- or micro-resolution is any behavior you commit to for four weeks. And even longer-term goals to, say, eat better or learn a new skill, can be broken down into more achievable goals on the way. Before you can land on Mars, focus on landing on the moon.

To create your micro-resolutions, you can start by thinking of 12 "bad" habits or indulgences you'd like to cut back on or give up entirely. This is what I did last year for what I called my "Year of Abstinence." My plan was to learn something about myself through self-denial, and it worked: I gave up alcohol, sweets, television and nine other things, but just for a month each. The mini-resolutions were as positive as they were eye-opening.

In order to simply increase my own, general awareness, every day in January my goal was to notice something new. I kept my eyes open, looked a bit longer, stopped to read the history markers, noticing buildings or took a different route than normal -- small ways to avoid sleepwalking through life.

The American philosopher Wilfrid Sellars was challenging this assumption when he spoke of “material inferences.” Sellars was interested in inferences that we can only recognize as valid if we possess certain bits of factual knowledge.

If we make room for such material inferences, we will be inclined to reject the view that individuals can reason well without any substantial knowledge of, say, the natural world and human affairs. We will also be inclined to regard the specifically factual content of subjects such as biology and history as integral to a progressive education.

according to Wittgenstein, is why it is wrong to understand algorithm-based calculations as expressions of nothing more than “mental mechanisms.” Far from being genuinely mechanical, such calculations involve a distinctive kind of thought.

our political “debates” seldom deserve the name. For the most part representatives of the rival parties exchange one-liners: “The rich can afford to pay more” is met by “Tax increases kill jobs.” Slightly more sophisticated discussions may cite historical precedents: “There were higher tax rates during the post-war boom” versus “Reagan’s tax cuts increased revenues.”

Such volleys still don’t even amount to arguments: they don’t put forward generally accepted premises that support a conclusion.

Despite the name, candidates’ pre-election debates are exercises in looking authoritative, imposing their talking points on the questions, avoiding gaffes, and embarrassing their opponents with “zingers”

President Bashar al-Assad’s main pitch to his people is that they are safer in the territory he controls, a far cry from the bombs and hunger on the rebels’ half of the storied and strategic city.This is what the government wanted international journalists to see when it invited a group into the country this week after years of keeping most out. But when I stepped off the bus, I found a war zone.

Dr. Mazen Rahmoun, a city health official in a neat brown suit, moved gingerly through the chaos with the preternaturally calm stare of a man long ago traumatized into numbness.

Instead, they are trying to break the siege, with Qaeda-linked groups and those backed by the United States working together — the opposite of what Russia has demanded.

The older seesaws were wooden planks that often hit asphalt directly, leading to occasional tailbone and spinal injuries, falls and pinched fingers, not to mention splinters. Children could slam each other by dismounting suddenly. Playgrounds that retained old seesaws were exposed to lawsuits.

“I think we have to take the kids out a little bit from the safety bubble,” she said, placing her 2-year-old daughter, Sadie, on a seesaw too.

“One little fall or a tooth broken and the next thing you know they are out,” she said.

The wealthy, says Smith, spend their days establishing an “economy of greatness,” one founded on “luxury and caprice” and fueled by “the gratification of their own vain and insatiable desires.” Any broader benefit that accrues from their striving is not the consequence of foresight or benevolence, but “in spite of their natural selfishness and rapacity.” They don’t do good, they are led to it.

Smith described this state of affairs as “the obvious and simple system of natural liberty,” and he knew that it made for the revolutionary implication of his work. It shifted the way we thought about the relationship between government action and economic growth, making less means more the rebuttable presumption of policy proposals.

What it did not do, however, was void any proposal outright, much less prove that all government activity was counterproductive. Smith held that the sovereign had a role supporting education, building infrastructure and public institutions, and providing security from foreign and domestic threats — initiatives that should be paid for, in part, by a progressive tax code and duties on luxury goods. He even believed the government had a “duty” to protect citizens from “oppression,” the inevitable tendency of the strong to take advantage of the ignorance and necessity of the weak.

few would have guessed that the economic order built upon Mr. Reagan’s and Mrs. Thatcher’s common faith in unfettered global markets (and largely accepted by their more liberal successors Bill Clinton and Tony Blair) would be brought down by right-wing populists riding the anger of a working class that has been cast aside in the globalized economy that the two leaders trumpeted 40 years ago.

The so-called Brexit vote was driven by an inchoate sense among older white workers with modest education that they have been passed over, condemned by forces beyond their control to an uncertain job for little pay in a world where their livelihoods are challenged not just by cheap Asian workers halfway around the world, but closer to home by waves of immigrants of different faiths and skin tones.

It is the same frustration that has buoyed proto-fascist political parties across Europe. It is the same anger fueling the candidacy of Mr. Trump in the United States.

A’s — once reserved for recognizing excellence and distinction — are today the most commonly awarded grades in America.

That’s true at both Ivy League institutions and community colleges, at huge flagship publics and tiny liberal arts schools, and in English, ethnic studies and engineering departments alike. Across the country, wherever and whatever they study, mediocre students are increasingly likely to receive supposedly superlative grades.

Analyzing 70 years of transcript records from more than 400 schools, the researchers found that the share of A grades has tripled, from just 15 percent of grades in 1940 to 45 percent in 2013. At private schools, A’s account for nearly a majority of grades awarded.
