Hindsight bias describes people’s tendency to overestimate how accurately they have predicted an event’s outcome after obtaining knowledge about it. Outcome knowledge has been shown to influence various forms of judgments, but it is unclear whether outcome knowledge also produces a hindsight bias on Judgments of Learning (JOLs). Three experiments tested whether people overestimated the accuracy of their memory predictions after obtaining knowledge about their actual memory performance. In all experiments, participants studied 60 cue-target word pairs, made a JOL for each word pair, and tried to recall the targets in a cued-recall test. In Experiments 1a and 1b, people recollected their original JOLs after attempting to recall each target, that is, after they obtained outcome knowledge for all items. In Experiments 2 and 3, people recollected their original JOLs in a separate phase after attempting to recall half the targets so that they had outcome knowledge for some but not all items. In all experiments, recollected JOLs were closer to actual memory performance than original JOLs for items with outcome knowledge only. Thus, outcome knowledge produced a hindsight bias on JOLs. Our results demonstrate that people overestimate the accuracy of their memory predictions in hindsight.
