kirk,noland,the,minute,men,narcissisticwomen,Research has long suggested that if you’re looking for someone who’s preening, strutting, self-absorbed, arrogant, exhibitionistic, conceited, insensitive and entitled, you’ll find more of them in the boys’ camp than you will in the girls’. So it comes as, well, almost no news at all that a new study — hold your applause till the end, please — found exactly that!

The research, in fairness, was sweeping: a meta-analysis of 355 journal articles and other studies going back 31 years. In the behavioral sciences, which lack the tidy, 1+1=2 certainty of fields like chemistry and physics and math, meta-analyses are often the best way to lock down a hypothesis. The paper did that, but it did more too — not just establishing the gender disparity but explaining why it exists.
