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

We comment on the proposition “that lower temperatures and especially greater seasonal variation in temperature calls for individuals and societies to adopt…a greater degree of self-control”, for which we cannot find empirical support in a large dataset with data-driven analyses. After providing more nuance in our theoretical review, we suggest revisiting their model with an eye to the social determinants of self-control.
