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.

Usage

MV23_SH

Format

A data frame with 1206 rows and 3 variables:

donate

[integer] did people choose to donate time? Either no (0) or yes (1)

condition

[factor] experimental condition, either an open-ended amount or a quantity.

amount

[integer] number of additional questionnaire (up to 3).
