The role of motivated science reception and numeracy in the context of the COVID-19 pandemic

The successful management of the COVID-19 pandemic depends on individuals accepting the current state of research and adhering to the preventive behaviors that follow from it. However, the processing of scientific results is not always rational, but influenced by prior attitudes as well as the ability to understand statistical data. Against this background, this study investigated the role of motivated reasoning and numeracy in the context of the current pandemic. To this end, participants (N = 417; US sample) evaluated two fictitious studies, one indicating that mask mandates in schools are an effective intervention to contain the spread of SARS-CoV-2, and one indicating that mask mandates in schools are counterproductive. Participants evaluated the studies in line with their prior attitude toward mask mandates. In addition, higher numeracy was associated with decreased bias, demonstrating that the ability to reason with numbers can lead to more accurate processing of statistical information.
