In Psychology And Other Social Sciences, Many Studies Fail The Reproducibility Test
The world of social science got a rude awakening a few years ago, when researchers concluded that many studies in this area appeared to be deeply flawed. Two-thirds could not be replicated in other labs. Some of those same researchers now report those problems still frequently crop up, even in the most prestigious scientific journals. But their study, published Monday in Nature Human Behaviour, also finds that social scientists can actually sniff out the dubious results with remarkable skill. First, the findings.

Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked? Or bashed the "close door" button in an elevator, while suspecting that it may, in fact, have no effect whatsoever? You're not alone, and you may be right.

How to Make the Best First Impression, According to Experts
Everyone can make snap judgments, especially when meeting someone new. In less than one-tenth of a second of seeing someone for the first time, our brain processes information about the person’s face—which leads to quick conclusions about a new acquaintance’s qualities, including trustworthiness, competency, friendliness, honesty and morality—according to a 2006 study published in Psychological Science. This tendency dates back to evolutionary times, when we would encounter strangers and, for survival purposes, need to assess whether they would inflict harm or be an ally, says Vivian Zayas, a professor of psychology at Cornell University.
