Effects of Fairness Perception on Cheating Behavior: An Experimental Study

Introduction: This study investigates how perceptions of fairness influence individual cheating behavior. Specifically, it explores whether different reward systems—based on equity (performance-based rewards) or equality (equal rewards for all)—affect the likelihood of dishonest actions in an experimental setting. Method: A two-phase laboratory experiment was conducted among 98 undergraduate students. Participants were randomly assigned to either an Equity or Equality treatment. In the second phase, they engaged in a task that allowed them to self-report outcomes tied to monetary rewards, providing a controlled measure of cheating behavior. Results or Findings: The results indicate that participants who perceived the reward system as unfair were significantly more likely to cheat. Cheating behavior was more prevalent in the Equality treatment group, especially among high performers, suggesting that equal reward distribution can induce perceptions of unfairness and trigger dishonest behavior. Discussion or Conclusion: The findings demonstrate the psychological importance of perceived fairness in ethical decision-making. Even in seemingly fair systems, perceptions of injustice can lead to rationalizations for dishonesty. This has implications for institutional design, particularly in education and workplace settings, where aligning incentives with perceived fairness can reduce unethical behavior.
