On the role of memory in misinformation corrections: Repeated exposure, correction durability, and source credibility

Abstract

Misinformation can negatively affect cognition, beliefs, and behavior, and thus contribute to societal disruption. Correcting misinformation can counteract these effects by updating memory and beliefs. In this selective review, we highlight recent perspectives on and evidence for the role of memory in the efficacy of correction methods. Two theoretical accounts propose that repeating misinformation can impair or improve correction efficacy to the extent that familiarity or integrative encoding prevails. We summarize evidence that recollection of corrections can counteract potential interference from misinformation repetitions on memory and belief updating. The efficacy of such updating also declines over time, especially when misinformation sources are not remembered. We call for more research on the role of memory in everyday misinformation corrections to better understand interactions among these processes.
