I’m sorely disappointed with the political science and economics literature on violence. Why do some people riot, destroy property, beat on others, or get into scraps? Is there any relationship between the propensities for interpersonal and communal or political violence?
I don’t buy the opportunity cost argument (crime maybe, aggression and riots, not so much) and “frustration-aggression” theories, while intuitive, don’t always merit the label ‘theory’.
Psychology, sociology and evolutionary biology must have interesting things to say, but Google scholar and various other sources are failing me. Pointers to interesting literatures will be appreciated.
