AMERICANS and Europeans stand out from the rest of the world for our sense of ourselves as individuals. We like to think of ourselves as unique, autonomous, self-motivated, self-made. As the anthropologist Clifford Geertz observed, this is a peculiar idea.People in the rest of the world are more likely to understand themselves as interwoven with other people — as interdependent, not independent. In such social worlds, your goal is to fit in and adjust yourself to others, not to stand out. People imagine themselves as part of a larger whole — threads in a web, not lone horsemen on the frontier. In America, we say that the squeaky wheel gets the grease. In Japan, people say that the nail that stands up gets hammered down.

Many concert-goers are often frustrated by the sound of people coughing during classical music performances. These coughers have now become the subject of an academic paper concerning "the economics of concert etiquette", which analyses a stark fact: people appear to cough more in concerts than in they do in normal life. The German economist Andreas Wagener told the Today programme: "The statistics indicate people cough during concerts twice as much as they do in normal life." Concert pianist Susan Tomes said: "I certainly do notice it, but I think it has something to do with the fact that people have gotten so used to hearing music amplified. "Many types of music are so loud, but classical music is not, and when you go to a classical concert, you forget how quiet acoustic instruments are." First broadcast on BBC Radio 4's Today Programme on Monday 28 January 2012.

If prolonged isolation is—as research and experience have confirmed for decades—so objectively horrifying, so intrinsically cruel, how did we end up with a prison system that may subject more of our own citizens to it than any other country in history has?

Anyone who has ever been in a meeting has seen the phenomenon of "Groupthink" first hand. The will of the crowd over shadows the wisdom of individuals and it can lead to dangerous consequences. Mike Williams asks why humans succumb to "Groupthink" and how we fight the tendency to follow the herd even if it leads to very perilous outcomes.

“Estimating the Reproducibility of Psychological Science,” from Science This paper isn’t really a study; it’s the outcome of an important movement in the field of psychology. In an effort called the Reproducibility Project, researchers at dozens of universities collaborated to replicate a hundred psychology studies that were initially conducted in 2008. They ended up replicating between a third and half of the studies. Is that result bad or good? It’s inevitable that studies won’t always be replicable—if every study could be replicated, then every researcher would be right the first time; even legitimate findings can prove fragile when you try to repeat them. All the same, the paper concludes that there is “room for improvement” in psychology, especially when it comes to “cultural practices in scientific communication.” Specifically, the authors propose that “low-power research designs combined with publication bias favoring positive results together produce a literature with upwardly biased effect sizes.” In other words, the desire for novelty drives researchers to overestimate the conclusiveness of their own work. It’s a fascinating and valuable effort to make sure that psychology moves forward in the best way possible.

A newly published paper suggests that personality similarity affects teachers' estimation of student achievement. That is, how much you are like your teacher contributes to his or her feelings about you — and your abilities. "Astonishingly, little is known about the formation of teacher judgments and therefore about the biases in judgments," says Tobias Rausch, an author of the study and a research scientist at the Otto-Friedrich-Universität Bamberg. "However, research tells us that teacher judgments often are not accurate."

For example, a recent study from Israel showed that teachers gave girls lower grades on math tests when they knew their gender. And lots of researchers have looked at the importance of having teachers who share the racial and socioeconomic backgrounds of their students.

TWO of our most vital industries, health care and education, have become increasingly subjected to metrics and measurements. Of course, we need to hold professionals accountable. But the focus on numbers has gone too far. We’re hitting the targets, but missing the point.

Traditional economic theory could not explain, much less predict, the near collapse of the financial system and its long-lasting effects on the global economy. Since the 2008 crisis, there has been increasing interest in using ideas from complexity theory to make sense of economic and financial markets.

It’s an intuitive claim, but also a profound one. It asserts that the benefits of bilingualism extend well beyond the realm of language, and into skills that we use in every aspect of our lives. This view is now widespread, heralded by a large community of scientists, promoted in books and magazines, and pushed by advocacy organizations.

Medical ailments, such as cancer and heart attacks, kill considerably more people each year than either guns or automobiles, according to the CDC. But firearms and motor vehicles are among the leading non-medical causes of mortality in the United States. They kill more people than falls do each year, and considerably more people than alcohol.

Does bad behavior in movies or other media lead people to behave badly? There’s plenty of research on the link between onscreen media and risky behaviors like unprotected sex, binge drinking, fast driving and even violence. One large meta-analysis of such studies concluded that exposure to risk-glorifying media is associated with risky behaviors by people who consume that media. But causality issues plague most studies in this area: People who engage in risky behaviors may prefer to consume risk-glorifying media. These studies also tend to measure attitudes in controlled lab settings rather than in real life.

Much of the moral case for bodycams, that they reduce police violence, rests on a single experiment: the 2012 Rialto study

Kids discover lying as early as age 2, studies have found. In one experiment, children were asked not to peek at a toy hidden behind them while the researcher withdrew from the room under false pretenses. Minutes later, the researcher returned and asked the child if he or she peeked.

5. The social science on gun violence is inconclusive.It will always be a given that it’s impossible to have real controlled experiments. The closest thing in this case would be to have two contiguous countries—both with similar “root” populations, and both subject to massive immigration from abroad.

A former journalist, equipped with an algorithm and the largest collection of murder records in the country, finds patterns in crime.
