Harvard Business Review sums up the research of quite a few recent studies. Seems the hope that each generation gets a little less awful is sadly not correct.
In February 2016 researchers at the National Institutes of Health published a study on how college biology students view their classmates’ intelligence and achievements. The researchers found that male students systematically overestimated the knowledge of the men in their classes in comparison with the women. Moreover, as the academic term progressed, the men’s faulty appraisal of their classmates’ abilities increased despite clear evidence of the women’s superior class performance. In every biology class examined, a man was considered the most renowned student — even when a woman had far better grades. In contrast, the female students surveyed did not show bias, accurately evaluating their fellow students based on performance. After studying the attitudes of these future scientists, the researchers concluded, “The chilly environment for women [in the sciences] may not be going away anytime soon.”
