The target article proposed that women display greater self-protectiveness than men to major physical and social threats because such self-protective responses have higher fitness value for women than men. Rather than having evolutionary roots, we suggest the various physiological, behavioral, and emotional responses to social and physical threats exhibited more by women than men are instead rooted in sociocultural forces.

We suggest in this commentary an emotional origin of the Industrial Revolution. Specifically, increased living standards directly preceding the Industrial Revolution produced increased happiness and subjective well-being that, in turn, fueled the explosion of innovation and economic growth experienced in industrial England.
