Leon has determined that “Temperature may be a proxy for UV radiation in the heat-aggression association. . . . Heat is associated with human aggression in field research, assumedly by affecting emotions, but it is not in laboratory experiments. Since this may be so because temperature functions as a proxy for UV radiation in field settings, not in the laboratory, this research tested, across 126 countries, whether temperature loses its predictive capacity when the electromagnetic variable is controlled. Temperature presented…
