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.
本研究旨在探究信息来源对新冠疫情风险感知的影响。本研究利用疫情早期在葡萄牙代表性人群中采集的样本数据（N=1411），发现尽管媒体来源的使用率更高，但科学来源在个人和社会层面的风险感知上发挥了更重要的作用；对科学来源的更高信任与更高的风险感知相关（即，放大的感知风险），而对社交媒体的信任与对个人威胁的轻视相关（即，减弱的感知风险）。这些发现表明，人们与科学的关系是风险感知的决定性因素，衡量这些关系的维度值得进一步研究。
