Common Heritable Effects Underpin Concerns Over Norm Maintenance and In‐Group Favoritism: Evidence From Genetic Analyses of Right‐Wing Authoritarianism and Traditionalism

Abstract: Research has shown that in-group favoritism is associated with concerns over the maintenance of social norms. Here we present two studies examining whether genetic factors underpin this association. A classical twin design was used to decompose phenotypic variance into genetic and environmental components in two studies. Study 1 used 812 pairs of adult U.S. twins from the nationally representative MIDUS II sample. Study 2 used 707 pairs of middle-age twins from the Minnesota Twin Registry. In-group favoritism … Show more

“…First, a pessimistic note: At least three important GHIC correlates have significant genetic underpinnings: authoritarianism (Lewis & Bates, ), empathic concern (Davis, Luce, & Krauss, ), and openness to experience (Jang, Livesley, & Vernon, ). GHIC consistently relates negatively to the first, positively to the latter two.…”

“…So whatever personality phenomenon you're studying (see Baumert et al, , for some suggestions), make sure you're measuring all six factors. To take one example, if you'd like to study genetic and environmental influences on personality variation, use the HEXACO factors, as some researchers have recently been doing (Kandler, Lewis, Butković, Vukasović Hlupić, & Bratko, ; Kandler, Richter, & Zapko‐Willmes, ; Lewis & Bates, ). Or if you're interested in ‘network approaches’ to personality, you should start with the HEXACO factors, as has recently been performed by Costantini et al ().…”

“…One of the main tenets of authoritarianism-in both its classic (Adorno et al, 1950) and modern (Altemeyer, 1981;Lewis & Bates, 2014) formulations-is the attachment to norms (conventionalism) mixed with aggression toward people who deviate from these norms. According to Lewis and Bates (2014), this mechanism for norm maintenance has common genetic underpinnings with one of the Big Five personality dimensions (low openness) and is connected with ingroup favoritism. Although the conformity to norms was considered in historical psychological research to be the cause of prejudice (Adorno et al, 1950;Allport, 1954;Frenkel-Brunswik, 1948)-it is currently often viewed as a potential limiting factor in prejudice (Crandall & Stangor, 2005).…”
