Reanalysis and perspective in the heat--aggression debate

B. J. Bushman, M. C. Wang, and C. A. Anderson argued that a reanalysis of E. G. Cohn and J. Rotton's Minneapolis data shows no inverted-U curvilinear relationship between temperature and aggression. Although B. J. Bushman et al.'s claim of no general inverted-U trend in the data might well be supported statistically, more careful examination of the subset of the data most likely to include the hottest temperatures in the study may offer at least some support for the inverted-U relationship. Aggregating data to describe a general trend minimizes the influence of outliers that may reflect alternative relationships, and such alternatives may be important practically and theoretically.
