Personality and political orientation: Meta-analysis and test of a Threat-Constraint Model

We synthesized and meta-analyzed 73 studies (N = 71,895) examining the associations between Big-Five personality and single-item self-placement measures of political orientation. Openness to Experience (r = −.18) and Conscientiousness (r = .10) were significantly but weakly correlated with political conservatism. The weak Openness-political orientation link was moderated by systemic threat and uncertainty (indexed by nation-wide homicide and unemployment). We propose a Threat-Constraint Model explaining this previously undetected Person × Situation interaction. The model shows that there was a moderately-sized negative correlation between Openness and political conservatism when systemic threat was low (r = −.422) but that this association was negligible at only moderate levels of threat (r = −.066). These findings highlight the economic and societal constraints of personality-political ideology associations.
