Rational thinking style, rejection of coronavirus (COVID-19) conspiracy theories/theorists, and compliance with mandated requirements: Direct and indirect relationships in a nationally representative sample of adults from the United Kingdom

Faced with the threat posed by the COVID-19 pandemic, many nations have mandated sets of requirements, such as social-distancing measures. However, compliance with such measures is likely to be shaped by a range of factors. Here, we proposed and tested a mediation model in which rejection of COVID-19 conspiracy theories and/or theorists mediates the relationship between rational thinking style and compliance with mandated requirements. An online, nationally representative sample of the adult population in the United Kingdom (N = 520) completed a previously validated measure of rational thinking style, as well as novel measures of rejection of COVID-19 conspiracy theories/theorists and compliance with mandated requirements. Intercorrelations between scores on all three measures were significant and positive. Mediation analysis indicated that rational thinking style and rejection of COVID-19 conspiracy theories/theorists, respectively, were directly associated with compliance, and that the mediated association was also significant. These results may have implications for practical policy aimed at promoting greater compliance with mandated requirements, including social distancing.
