> When prosociality was measured using self-report trait scales, the picture was considerably clearer in favor of a substantive link between prosociality and political orientation: All but one of the 50 correlations considered were meaningful (i.e., r≥ |.10|), and all these correlations were in the same direction. That is, participants with a stronger left-wing orientation reported higher levels of trait prosociality. Given the subject matter, this seems completely unsurprising and almost completely meaningless: left-leaning participants claim to be more pro-social. > When prosociality was measured in economic games, we only found a few meaningful correlations with political orientation, mostly for SVO. Except for one indicator of political orientation (i.e., economic political orientation), higher (i.e., more prosocial) levels of SVO were associated with greater preference for left-wing ideologies and parties. However, effect sizes were small throughout, reaching a maximum of r = –.15. In turn, none of the other behavioral (game-based) measures of prosociality yielded consistent relations with political orientation. Also, the sample size-weighted average correlation of political orientation with prosocial behavior across all games employed failed to reach our predefined criterion of a meaningful effect (r < |.10|). Overall, these findings replicate previous research, which likewise showed most consistent links between political orientation and prosocial behavior when the latter was operationalized through SVO (Balliet et al., 2018; Chirumbolo et al., 2016; Sheldon & Nichols, 2009; van Lange et al., 2012). When measured with even a little indirection? The effect all but disappears.
