Across cultures, women are *much* higher than men on fearful personality traits. Why?

Our new SPPS paper—led by Joe Manson w/ Kristine Chua, @rodriguezNina_ @michael_barlev @durkeepk—provides an answer

tl;dr the sex diff in fear is mediated by that in physical strength

1/x Image Evidence supports the hypothesis that, b/c weaker people r more vulnerable 2 threats, the fear system’s activation threshold is calibrated 2 relative strength

@rodriguezNina_ & I showed this within sex: strong women(men) > fear than weak women(men)
