About this study
As part of a larger study, participants are told to read 1 out of 4 anecdotes depicting an organ donation scenario where they are required to make a decision on behalf of their mother who has just suffered an accident. The participants are then surveyed on their attitudes towards organ donation.
Read the detailed description
As part of a larger study, participants are given 1 out of 4 possible vignettes which depicts an organ donation scenario involving their mother. The possible vignettes consist of a Control condition, a Framing condition, a Normative condition and a condition that includes all the nudges. Participants are then given surveys to gauge their views and attitudes towards organ donation as a whole, their trust towards medical institutions and the doctors, their perceived manipulation from the doctor and their views on the altruistic nature of organ donation.
