Perceptions of unfairness in allocations between multiple recipients

Area of Science:

• Social Psychology
• Behavioral Economics
• Decision Science

Background:

• Existing models of fairness perceptions in resource allocation primarily focus on the allocator's share relative to recipients.
• Limited attention has been given to the impact of disparities among recipients on fairness judgments.

Purpose of the Study:

• To introduce and validate a novel model explaining perceptions of unfairness in multi-recipient resource allocations.
• To investigate the role of inter-recipient disparities, specifically the impact of a single loser, on fairness perceptions.
• To identify and characterize individuals with heightened sensitivity to being a sole loser (ostraphobics).

Main Methods:

• Development of a new theoretical model for fairness perceptions.
• Empirical testing of model predictions through a series of controlled experiments.
• Analysis of individual differences in sensitivity to fairness dimensions and psychological correlates.

Main Results:

• The model successfully predicted perceptions of unfairness, confirming novel predictions beyond judge-recipient share comparisons.
• The presence of a single loser significantly increased perceived unfairness.
• Empirical evidence supports the existence and prevalence of 'ostraphobics'—individuals highly sensitive to being the sole loser—who exhibit stronger unfairness perceptions and distinct psychological profiles.

Conclusions:

• Fairness perceptions are influenced not only by one's own outcome but also by the relative outcomes of others.
• The 'single loser' effect is a critical, previously underemphasized factor in resource allocation fairness.
• Ostraphobia represents a significant individual difference dimension impacting fairness judgments and potentially leading to unique behavioral patterns.
