The Effect of 9/11 on the Heritability of Political Trust

Abstract

Following the attacks of September 11, 2001, a rally effect led to a precipitous rise in political trust. However, the increase in political trust concealed a simultaneous decline among a smaller portion of the population. This article examines the psychological mechanisms underlying these heterogeneous attitudes towards government and shows that a biosocial model best explains the observed patterns of response. The interplay of genetic and environmental factors of political trust reveals the stable but dynamic nature of heritability: genetic influences of political trust increased immediately following 9/11 but quickly decayed to pre‐9/11 levels.
