Of Pandemics, Politics, and Personality: The Role of Conscientiousness and Political Ideology in Sharing of Fake News
Sharing of misinformation can be catastrophic, especially during times of national importance. Typically studied in political contexts, sharing of fake news has been positively linked with conservative political ideology. However, such sweeping generalizations run the risk of increasing already rampant political polarization. We offer a more nuanced account by proposing that the sharing of fake news is largely driven by low conscientiousness conservatives. At high levels of conscientiousness there is no difference between liberals and conservatives. We find support for our hypotheses in the contexts of Covid-19 and political news across 7 studies (six pre-registered; one conceptual replication) with 4,149 participants and 84,556 unique participant-news observations. Furthermore, our findings suggest the inadequacy of fact-checker interventions to deter the spread of fake news, and that a general desire for chaos drives the interactive effect of political ideology and personality on the sharing of fake news. This underscores the challenges associated with tackling fake news, especially during a crisis like Covid-19 where misinformation threatens to exacerbate the pandemic even further.
