Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
