Not taking responsibility: Equity trumps efficiency in allocation decisions.

Area of Science:

• Social Psychology
• Behavioral Economics
• Decision Science

Background:

• Resource allocation often presents a conflict between equity and efficiency.
• Scarcity can lead to resource destruction to maintain perceived equity.
• The psychological drivers behind aversion to inequitable outcomes require further investigation.

Purpose of the Study:

• To investigate whether aversion is directed at inequitable outcomes themselves or at the responsibility of implementing them.
• To understand the psychological mechanisms underlying decisions in resource allocation dilemmas.
• To explore factors influencing the avoidance of making decisions that result in inequity.

Main Methods:

• Conducted three scenario-based experiments to simulate resource allocation choices.
• Employed one incentivized experiment to observe real-world decision-making under potential consequences.
• Varied the decision-maker's role and the availability of random allocation tools.

Main Results:

• Participants demonstrated 'inequity responsibility aversion,' preferring to discard resources rather than choose recipients.
• This aversion significantly decreased when a random device was available for allocation.
• Findings suggest a stronger aversion to the responsibility of implementing inequity than to inequity itself.

Conclusions:

• Individuals are psychologically averse to being directly responsible for creating or implementing inequitable distributions.
• The use of random mechanisms can mitigate the burden of responsibility in such scenarios.
• Understanding inequity responsibility aversion is crucial for designing fair and efficient resource allocation systems.
