False Memory
A false memory is a recollection of an event or detail that did not happen as remembered. It can involve a small distortion or a remembered event that never occurred. The person may sincerely believe the recollection. Confidence and vividness alone cannot establish accuracy, and a false memory is different from a deliberate lie.

Evidence for the claims on this page: Experimental evidence within defined tasks
The cited experiments demonstrate inaccurate memory reports under particular procedures. They do not establish the accuracy of any individual recollection.
How to read this assessmentWhat it is
False memory refers broadly to recollection that includes events or details that did not occur, or that differs substantially from the original event. (Loftus and Palmer, 1974; Wade et al., 2002)
In everyday language
A memory may feel real even when a detail, or the whole event, is inaccurate.
What it isn't
It is not necessarily deliberate lying and is not equivalent to ordinary uncertainty.
An example
A viewer remembers broken glass in a filmed collision even though the film showed none. Confidence in that memory does not make the detail accurate.
Key features
- Subjective feeling of remembering
- Mismatch with the documented event
- Can arise through multiple mechanisms
How it relates to synthetic imprinting
False memory is one outcome the framework might investigate. A lasting change in expectations or beliefs need not involve a false memory.
Research context
Loftus and Palmer tested reports about a filmed collision, including a detail that was absent. Wade and colleagues tested recollections prompted by a doctored childhood photograph and repeated interviews. These procedures illustrate different ways inaccurate memory reports can arise. (Loftus and Palmer, 1974; Wade et al., 2002)
A closer look at the cited studies
| Research question | Can question wording affect reports of a filmed collision? |
|---|---|
| Participants | 45 students in Experiment 1; 150 students in Experiment 2. |
| Design and comparison | Participants watched collision films. Questions used different verbs; Experiment 2 also included a group without a speed question. |
| Measured findings | Speed estimates varied with wording. In Experiment 2, the “smashed” group more often reported glass that the film did not show. |
| Timing and follow-up | Speed estimates were collected after viewing. Experiment 2 tested the glass report one week later. |
| Limits on interpretation | Student samples, short films, and prompted reports limit generalization. This study did not test AI media or effects beyond the measured interval. |
| Research question | Can a fabricated personal photograph, together with retrieval prompts, elicit false childhood recollections? |
|---|---|
| Participants | 20 participants, with family informants helping supply photographs and check the invented event. |
| Design and comparison | A doctored balloon-ride photograph appeared alongside three genuine photographs. Interviews used repeated prompts and guided imagery. |
| Measured findings | By the final interview, 10 participants reported partial or clear false recollections of the invented event. |
| Timing and follow-up | Three interviews across 7–16 days, followed by debriefing. This was repeated exposure during the study, not a test of persistence after correction. |
| Limits on interpretation | The small sample and combined procedure cannot isolate a photograph-only effect or estimate how often ordinary viewing changes memory. |

Revision history
- Version 1.4 · Current
Added claim-level citations and a separate assessment of evidence support. The opening definition is unchanged.

A false memory is a recollection of an event or detail that did not happen as remembered. It can involve a small distortion or a remembered event that never occurred. The person may sincerely believe the recollection. Confidence and vividness alone cannot establish accuracy, and a false memory is different from a deliberate lie.
