Underlying wishes and nudged choices

Area of Science:

• Behavioral Economics
• Public Health Policy
• Social Psychology

Background:

• Family vetoes of deceased organ donor choices are common.
• Legislative systems for organ donation vary globally, influencing inferred donor intent.
• Understanding perceived donor preference is crucial for organ procurement.

Purpose of the Study:

• To investigate how different organ donation legislative systems affect the perceived strength of a deceased individual's donation preference.
• To compare mandated choice and automatic default (nudged) systems in inferring true wishes.
• To assess if nationality influences these perceptions.

Main Methods:

• Three studies involving American and European participants.
• Participants judged the likelihood of a decedent's true wish to donate organs.
• Random assignment to four legislative systems: default opt-in, default opt-out, mandated choice, and mandatory donor.

Main Results:

• Participants perceived stronger underlying donation preferences under default opt-in and mandated choice systems.
• Perceptions were weaker for default opt-out and mandatory donor systems.
• Findings were consistent across participants from different countries.

Conclusions:

• Legislative system design significantly influences the inferred strength of organ donation preferences.
• Default opt-in and mandated choice may lead to stronger perceived donor intent.
• Addressing uncertainty in inferred preferences from nudged choices is essential for organ donation policy.
