In science we trust: the effects of information sources on COVID-19 risk perceptions

The goal of this study was to investigate the effects of sources of information on COVID-19 risk perceptions. Using data from a representative sample of the Portuguese population (N = 1,411) collected early in the pandemic, we find that while media sources were more frequently used, scientific sources played a more important role on perceived personal and societal-level risks; higher trust in scientific sources associated with increased risk perceptions (i.e., amplified perceived risk), trust in social media associated with dismissing personal threat (i.e., attenuated perceived risk). These findings suggest that people’s relations with science were determinant factors in risk perceptions, and dimensions that measure these deserve further investigation.
