When things don't add up: the role of perceived fungibility in repeated-play decisions.
Previous research on repeated-play decisions has focused on choices with fungible outcomes. We investigated the perceived fungibility of outcomes over repeated plays of risky prospects in several situations, as well as the relationship between perceived fungibility and preferences for taking risks in those situations. Perceived fungibility varied substantially across participants and situations, with outcomes experienced by different people (e.g., medical outcomes for different patients) receiving lower scores than outcomes experienced by a single person. Higher perceived fungibility was associated with more favorable evaluations of repeated plays of risky prospects with positive expectations. Additionally, perceived fungibility moderated the effect of repetition, such that the increased attractiveness of repeated plays relative to a single play was diminished when perceived fungibility was low. Although evaluating the overall distribution of outcomes is arguably rational when monetary outcomes accrue to one person, treating each play as a separate event may be more appropriate when outcomes are not viewed as fungible.
