A fascinating study published today shows that women are more prone to intrasexual (i.e. aimed at members of the same sex) jealousy and envy than men. Women were more jealous of other women’s attractiveness and envious of another woman’s position or power. Men showed no such feelings toward other men. Both sexes, however, felt jealousy or envy when contemplating a same-sex person’s professional or social skills. The take out, the researchers claim, is that all employees should be trained in good social skills.
