  1. Two experiments examined the polarization of public support for COVID-19 policies due to people’s (lack of) trust in political leaders and nonpartisan experts. In diverse samples in the United States (Experiment 1; N = 1,802) and the United Kingdom (Experiment 2; N = 1,825), participants evaluated COVID-19 policies that were framed as proposed by ingroup political leaders, outgroup political leaders, nonpartisan experts, or, in the United States, a bipartisan group of political leaders. At the time of the study in April 2020, COVID-19 was an unfamiliar and shared threat. Therefore, there were theoretical reasons suggesting that attitudes toward COVID-19 policy may not have been politically polarized. Yet, our results demonstrated that even relatively early in the pandemic people supported policies from ingroup political leaders more than the same policies from outgroup leaders, extending prior research on how people align their policy stances to political elites from their own parties. People also trusted experts and ingroup political leaders more than they did outgroup political leaders. Partly because of this polarized trust, policies from experts and bipartisan groups were more widely supported than policies from ingroup political leaders. These results illustrate the potentially detrimental role political leaders may play and the potential for effective leadership by bipartisan groups and nonpartisan experts in shaping public policy attitudes during crises.

  2. Although social scientists have examined how political speeches may help forge and/or shape collective memories, they have done so with little to no input from psychologists. We address this deficit, demonstrating how a modified version of a well-established and empirically derived psychological phenomenon—socially shared retrieval-induced forgetting—helps explain the mnemonic consequences associated with political speeches, in this case, the Belgian King’s 2012 summer speech. To this end, we analyzed the responses of 43 French speakers and 49 Dutch speakers. Of these individuals, 35 attended to the speech (16 French speakers; 19 Dutch speakers). Our results suggest that the Belgian King’s speech induced French-speaking Belgians who attended the speech to recall less information related to what the King mentioned in the speech. We found no such deficit for Dutch-speaking Belgians. Rather, the Dutch-speaking Belgians exhibited a trend toward greater recall of related and unrelated information when attending relative to not attending to the speach. These results bolster the importance of including a psychological approach in the study of collective memories and the moderating role of social identity.
