Psychological entitlement describes the dispositional tendency to claim excessive and unearned rewards and resources, and to demand undeserved special treatment. In one experiment, one cross-sectional survey, and one time-separated survey (total n = 721), we show that psychological entitlement is associated with general conspiracy theory endorsement, COVID-19 specific conspiracy theory endorsement, and conspiracy theorizing as an overarching cognitive style. We find those high in entitlement are more likely to report having made discretionary visits to non-essential venues and services (e.g. buffets, spas, casinos) during the pandemic, and that these risky public health behaviors are mediated through beliefs in conspiracy theories. We identify consequences for public health behavior and conclude with a research agenda for better understanding the underlying mechanisms linking entitlement and conspiracy beliefs.
