You do know that my academic background is in Anthropology, right? (Historical Ethnology specifically-)... 'Have the economically-useless university degrees and everything. 😝
There are no absolute universals when it comes to human behavior, but some underlying patterns are reasonably well established. The fact that we're pretty typical of troupe primates in more ways than some of us might be comfortable with hasn't really been up for debate in... well, decades, honestly. That strong preference for in-group/out-group social constructs and for forming hierarchies within and between discreet groups that I mentioned? Social Psychologists figured that one out long before the evolutionary types got in on it.
Anyway, a real throw down on the good, the bad and the ugly of evolutionary psychology and exactly how it relates to ourselves and our primate cousins is pretty well outside the scope of a thread about dealing with assholes and blow-hards in a superhero MMO. If anyone is really interested, there have been reams written on the subject.
