Observations are individual subjects in our primary analysis. If subjects completed multiple responses, we provide the mean over all surveys for the subject. Male and Age variables are indicators of the given characteristic. COVID-19 Symptom is an indicator variable for whether the subject, or anyone with which they are living with, experienced shortness of breathe, cough, or fever in the previous 7 days. Risk Tolerant is a self-reported preference of risk on an 11-point scale, increasing in risk tolerance. Altruism Donation is the amount of an unexpected US$1600 that one would donate to a good cause, and is an underlying measure in our main altruism measure. Altruism Scale is a self-reported preference of the willingness to give on an 11-point scale, increasing in altruism, and is an underlying measure in our main altruism measure. High Risk is an indicator for whether the subject, or anyone they are living with, has a characteristic associated with increased likelihood of severe illness from COVID-19. Serious, Health Effective, and Econ Effective are five-point scales that reduce in the belief of how serious a COVID-19 infection is for younger healthy adults, how effective social distancing is at reducing the spread of the virus, and how effective social distancing is at reducing the economic impact from the virus, respectively. Unemployment is the expected unemployment rate in June 2020. Low SD, Misperceptions, Low SD, Externalities, Hosp. Rate, and Potential Spread are responses to questions that are based on factual information provided in initial surveys, as described in the Online Appendix.
