Does distance from the equator predict self-control? Lessons from the Human Penguin Project

Abstract

We comment on the proposition "that lower temperatures and especially greater seasonal variation in temperature call for individuals and societies to adopt ... a greater degree of self-control" (Van Lange et al., sect. 3, para. 4) for which we cannot find empirical support in a large data set with data-driven analyses. After providing greater nuance in our theoretical review, we suggest that Van Lange et al. revisit their model with an eye toward the social determinants of self-control.
