Anger

Are angry women more like men? 

"Why is it that men can be bastards and women must wear pearls and smile?"In two studies, researchers asked subjects to identify the sex of a series of faces. In the first study, androgynous faces with lowered eyebrows and tight lips (angry expressions) were more likely to be identified as male, and faces with smiles and raised eyebrows (expressions of happiness and fear) were often labeled feminine.This research is part of a larger set of studies showing that men's faces are perceived as angrier and women's faces as happier.
