Policy measures to curb the coronavirus epidemic have turned the world upside down, and the true impact of this global pandemic is yet to be seen. Researchers are still learning more about the virus every day, but how do members of the general public perceive the risks associated with COVID-19? Do these beliefs affect what people have been doing to protect themselves? As social scientists, we’re interested in understanding how people’s beliefs and behaviors evolved in the face of this novel threat. We launched a survey through the University of Southern California’s Understanding America Study to find out. Running from March 10 through March 16, the survey covered a period of time when the information available to the public and the situation on the ground were both rapidly changing. We were able to see how people’s perceptions of risk and their actions were changing from day to day. As this crisis continues, it is important to understand what people think about the risks and how they are behaving. If, for example, people are seeing low risks and not implementing recommended actions, then public health communications may need to address that.
