I don't know about this trend of evo pysch explanations, but I'm only posting this because short men are stereotyped as bullies. Evil short boss, cop, villain, etc. Most short men I see are meek and cowardly, because they've been beaten down by society.
You need to have some sense of power to pick on someone, even those weaker than yourself. I've seen many short men who are afraid kids and women can beat them up, let alone other men. Short men literally think they have no power, except perhaps over babies and the disabled.
Obviously there are outliers for every group, but it's strange how short men get "short man syndrome" while tall men get "gentle giant." Do short men have more self-esteem on average? Rhetorical question.
