Overcoming the outcome bias: Making intentions matter

• We examine interventions aimed to mitigate the outcome bias and intentions neglect.
• We study the impact of joint vs. separate evaluation on the outcome bias.
• The outcome bias is reduced under separate evaluation relative to joint evaluation.
• Joint evaluation makes attending to information about intentions more difficult compared to separate evaluation.

People often make the well-documented mistake of paying too much attention to the outcomes of others’ actions while neglecting information about the original intentions leading to those outcomes. In five experiments, we examine interventions aimed at reducing this outcome bias in situations where intentions and outcomes are misaligned. Participants evaluated an individual with fair intentions leading to unfavorable outcomes, an individual with selfish intentions leading to favorable outcomes, or both individuals jointly. Contrary to our initial predictions, participants weighed others’ outcomes more—not less—when these individuals were evaluated jointly rather than separately (Experiment 1). Consequently, separate evaluators were more intention-oriented than joint evaluators when rewarding and punishing others (Experiment 2a) and assessing the value of repeated interactions with these individuals in the future (Experiment 2b). Third-party recommenders were less outcome-biased in allocating funds to investment managers when making separate evaluations relative to joint evaluations (Experiment 3). Finally, raising the salience of intentions prior to discovering outcomes helped joint evaluators overcome the outcome bias, suggesting that joint evaluation made attending to information about intentions more difficult (Experiment 4). Our findings bridge decision-making research on the outcome bias and management research on organizational justice by investigating the role of intentions in evaluations.
