Abstract
Conspiracy theories thrive in moments of crises because they provide straightforward answers that assist individuals in coping with threats. The COVID-19 outbreak is such a crisis and is boosted by the political turmoil related to the politicization of the pandemic in some countries. To assess the role of political partisanship, intolerance of uncertainty (IU), and conspiracy beliefs in our two criterion variables (support for COVID-19 prevention measures and compliance with social distancing), we applied an online questionnaire to 662 participants. Our results indicate direct effects of political partisanship on support for COVID-19 prevention measures and non-compliance with social distancing while IU has not directly affected any of them. We have also found a significant effect of political partisanship on conspiracy theory dimensions involving personal wellbeing (PW) and control of information (CI) but not government malfeasance (GM) ones. Moreover, beliefs in CI theories predicted non-compliance with social distancing. Intolerance of uncertainty, on its turn, predicted the three dimensions of conspiracy beliefs. As to interaction effects, belief in GM, PW, and CI conspiracy theories moderated the effect of political partisanship on support for COVID-19 prevention measures whereas only belief in GM and PW theories moderated the effect of IU on past non-compliance with social distancing. Overall, our results suggest the relevance of diminishing politicization around the virus, providing basic scientific knowledge to the general population, and assisting individuals in coping with uncertainty. Besides, these findings provide insights into developing information campaigns to instruct the population to cope with the pandemic, producing behavioral change at societal and individual levels.
