Moon and vanEpps (2023), Supplementary study H
MV23_SH.Rd
After completing an unrelated study, the authors proposed to participants on MTurk to donate of their time for a social cause (net neutrality) by completing an optional survey for a prosocial cause. Participants were assigned to the open-ended choice or offered to complete up to 3 additional sections with demographics (1), plus internet use (2) and political attitudes (3). The study aims to study generosity, but without involving windfall.
Format

donate
[integer] did people choose to donate time? Either no (
0
) or yes (1
)condition
[factor] experimental condition, either an
open-ended
amount or aquantity
.amount
