ScienceBlog -- Manhood is a “precarious” status — difficult to earn and easy to lose. And when it’s threatened, men see aggression as a good way to hold onto it. These are the conclusions of a new article by University of South Florida psychologists Jennifer K. Bosson and Joseph A. Vandello. The paper is published in Current Directions in Psychological Science, a journal of the Association for Psychological Science. “Gender is social,” says, Bosson. “Men know this. They are powerfully concerned about how they appear in other people’s eyes.” And the more concerned they are, the more they will suffer psychologically when their manhood feels violated. Gender role violation can be a big thing, like losing a job, or a little thing, like being asked to braid hair in a laboratory.
