Several recent studies have found that women physicians are paid less than male physicians - about 10% less after accounting for all potential confounders - and are less likely to promoted within academic medical centers. A new study published in Perspectives on Psychological Science, a journal of the Association for Psychological Science, describes a theory explaining how the difference comes about: the root cause is that boys are just more interested in technical things, like taking . That is, many people believe that boys and men are better at math than girls and women and, further, that this difference is biological (hormonal, neurological, or somehow encoded on the Y chromosome).
