SUMMARY OR ABSTRACT
Text of Note
Violence is a prominent part of human history as well as modern society. In this study, literature describing social, cognitive, and evolutionary psychological models of aggression is discussed. Based on this discussion, it is suggested that evolutionary psychology provides an encompassing framework for explaining and predicting violent behavior. Public data on homicide rates throughout the United States are used along with census data to support an evolutionary psychological explanation of violence. Specifically, a negative binomial regression model was applied to determine if sex ratio, marriage rates, male age trends, police presence, poverty level, and population density are correlated with homicide rates across United States Metropolitan Statistical Areas. It was found that marriage rates, poverty, and population density were correlated with homicide rates in the predicted directions. Male age trends were correlated with homicide rates in an unexpected direction, while sex ratio and police presence were not significantly associated with homicide rates.
