dc.description.abstract | Is the phenomenon of people overestimating their skill relative to their peers (overplacement) exacerbated by group affiliation? Social identity theory predicts people evaluate in-group members more positively than out-group members, and we hypothesized that this differential treatment may result in greater overplacement when interacting with an out-group member. We tested this hypothesis with 301 US voters affiliated with either the Republican or Democratic party in the run-up to the 2020 Presidential election, a time when political identities were salient and highly polarized. We found there is a higher tendency for overplacement when faced with an out-group opponent than with an in-group opponent. Decomposition analysis suggests this difference is due to underestimating the opponent, as opposed to overestimating one’s own performance to a higher degree. Moreover, any tendency to incur in overplacement is mitigated when faced with an opponent with the same political identity relative to one with a neutral one. Group affiliation biases initial priors, but not how they are updated. | en_GB |
