Each session is similar and includes a social values orientation test (SVO; Murphy et al., 2011), a trust game and a questionnaire to measure the degree of social distancing from family and friends, and the social norm in the face of violating the distancing rule. These measures identify the individual's degree of pro-sociality, his propensity to trust others and reciprocate that trust, and his perception of the social norm regarding violation of the social distancing rule. Repeating the measures every week for 3 months enables us to measure the evolution of preferences as a function of the tightening of the lockdown measures and their subsequent lifting. null France Individuals General population Male Female Other Young Adult (19 to 24 years) Adult (25 to 44 years) Middle Aged (45 to 64 years) Other Other Other Online experimentation using digital tools Observational Study Observational Study Unknown Embargoed access Data made available as soon as research articles are published.
