The role of climate in human aggression and violence: Towards a broader conception.

Abstract

The psychological processes that predict aggressive behaviour are also typically associated with violent self-harm (e.g., poor self-control). Yet, although human violence (towards others) appears to increase with proximity to the equator, suicide rates tend to decrease. In the light of this empirical puzzle, I argue that Van Lange et al.'s CLASH model would benefit from a broader conceptualization of human aggression.
