What is memory suggestibility?
Short answer
Image: pmc.ncbi.nlm.nih.gov
Memory suggestibility is the tendency for post-event information—such as misleading questions, suggestions, or other people’s accounts—to influence later recollection. It can alter details of an actual event and, under some conditions, contribute to memories of events that did not occur. Research supports meaningful effects, including in adults and children, but findings also indicate that effects depend on factors such as plausibility, familiarity, the type of suggestion, and how memory is tested.

A serious dissenting position does not deny that suggestions can alter recollection, but questions claims that entirely fictional events are easily implanted or that suggestibility is a single, powerful trait. This view emphasizes methodological limits in false-memory paradigms and argues that effects are constrained by plausibility, familiarity, expectations, and whether a suggestion changes an existing memory or attempts to create one from scratch.
- The construct of suggestibility may combine distinct processes, including compliance, imagination, uncritical acceptance, and memory change, making one global trait difficult to measure.
- Research reviewed by Pezdek identifies constraints involving event familiarity, expectations, the kind of memory change requested, and the plausibility of the suggested event.
- Recent critiques argue that false-memory implantation studies may overstate how readily entirely fictional events can be created and raise concerns about their reliability and generalisability.
- This position accepts distortion from misleading information while disputing stronger claims that suggestion alone routinely produces fully formed memories of fictional events.
