Table 3. Wording of Questions for Probability Perception Measure in the Different Conditions in Studies 1–4.

Question about infection probability (all studies)	Question about hospitalization probability given infection (studies 1, 2, and 4)
Note. Participants were also given the following instruction for how to provide their answer: “Your answer can range from 0% to 100% and can include up to three decimal places (e.g., enter 0.01% for a chance of 1 in 10,000).” Individuals and ages in the square brackets were either a child < 18 years, a healthy adult aged 18–50 years, or an older adult aged >70 years, depending on the condition in the study. For Study 1, the two younger age groups were grouped and averaged to represent “nonvulnerable” individuals.
Could you please evaluate the chances that [a child/a healthy adult/an older adult] aged [X years] contracts the new coronavirus over the next 30 days?	Assuming that [a child/a healthy adult/an older adult] aged [X years] has contracted a coronavirus infection, could you please evaluate the chances that this [child/person] will need to be hospitalized (e.g., because of developing pneumonia caused by the virus)?
