People who learn the outcome to a situation or problem tend to overestimate what was known in the past-this is hindsight bias. Whereas previous research has revealed robust hindsight bias in the visual domain, little is known about how outcome information affects our memory of others' emotional expressions. The goal of the current work was to test whether participants exhibited hindsight bias for emotional faces and whether this varied as a function of emotion. Across five experiments, participants saw images of faces displaying different emotions. In the foresight phase, participants watched several emotional faces gradually clarify from blurry to clear. Once participants believed they knew what emotion the face was exhibiting, they identified the emotion from several options (e.g., angry, disgusted, happy, scared, surprised). In the hindsight phase, participants saw clear versions of each face before stopping the clarification at the point at which they previously identified the emotional expression. On average, participants exhibited hindsight bias for all emotions except happy faces (i.e., they indicated that they identified the emotional expressions at a blurrier point in hindsight than they had in foresight). A multinomial processing tree model of our data revealed that this was not due to participants' better recollection of foresight judgments for happy faces compared to the other emotions. Additionally, participants showed a smaller reconstruction bias for happy faces than the other emotions. We discuss the social implications of these findings as well as the potential for this paradigm to be used across cultures and ages. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
