Secondary Outcomes (end points)
The index also includes a list of secondary outcomes: how important is hand washing or hand sanitising, participation of activities in a hypothetical awareness campaign, and an option to make a donation to Long COVID research, with the chance of being selected for donation matching, as well as a guess to total group donation. The independent variables are observability and prosociality. Observability is a dummy variable that takes on the value of 1 if the participant is in the public condition, and 0 if in the private condition otherwise. Prosociality is also a dummy variable. Participants are asked to estimate the amount of their total group donation. Using the median of all estimates, participant whose estimates go above is identified as more prosocial, vice versa. The control variables include gender, ethnicity, and education.
