Not so fast -- sex differences in the brain are overblown
People love to speculate about differences between the sexes, and neuroscience has brought a new technology to this pastime. Brain imaging studies are published at a great rate, and some report sex differences in brain structure or patterns of neural activity. But we should be skeptical about reports of brain differences between the sexes, writes psychological scientist Cordelia Fine in Current Directions in Psychological Science, a journal of the Association for Psychological Science. The results from these studies may not necessarily withstand the tests of larger sample sizes or improved analysis techniques—and it's too soon to know for sure what such results, even if they prove to be reliable, might mean for differences in male and female minds.
