What Is a Flashbulb Memory? Vivid Recollections That Are Frequently Wrong
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
People remember where they were when they heard shocking news with unusual vividness and confidence. Studies that recorded those accounts at the time and checked them years later found that the confidence survives and the accuracy does not.
What the phenomenon is
The term describes a memory of the circumstances in which a person learned of a surprising and consequential event, typically including where they were, who told them, what they were doing and how they felt, held with unusual vividness and detail and with strong confidence in its accuracy. The original proposal suggested a special biological mechanism producing an unusually durable record under emotional arousal, comparable to a photograph. Such memories concern the circumstances of learning rather than the event itself, which is a distinction that matters, since a person recalling a public event is usually recalling their own moment of hearing about it. The phenomenon is real as a description of how such memories feel, and the question the research addressed is whether the feeling corresponds to accuracy.
What the studies found
The research design is straightforward and the results are consistent:
- •Accounts collected within a day or two of a major event, then collected again after months and years
- •Substantial inconsistency between the original and the later accounts, with details changed, added or lost
- •Confidence remaining high regardless of how much the account had changed
- •No relationship between how confident a person was and how accurate their account proved
- •Rates of consistency comparable to memories for ordinary events, once the emotional intensity is accounted for
- •Participants shown their own original accounts frequently insisting the later version was correct
Why confidence and accuracy separate
The explanation for the mismatch is more interesting than the finding. Vividness and confidence appear to track how often and how intensely a memory has been recalled and rehearsed rather than how faithful it is, and memories of major events are rehearsed constantly, discussed with others and reinforced by media coverage. Each recollection is a reconstruction rather than a retrieval, and the reconstruction incorporates whatever is available at the time, including details from other accounts and from later coverage, which are then stored as part of the memory. Emotional arousal does improve memory for the central details of an experienced event, which is well established and is a different claim from accuracy about the circumstances of hearing news. The phenomenon is therefore a case of the subjective feeling of remembering coming apart from the reliability of what is remembered.
How memory actually works
The findings here are one instance of a general picture that has replaced the idea of memory as storage and retrieval. Recalling something reconstructs it from fragments, from general knowledge about how such situations go and from whatever is currently available, which is why memories incorporate later information and why they change each time they are recalled. Retrieving a memory makes it temporarily unstable and it is restored afterwards in a modified form, which is a documented process and which means frequent recall is a route to alteration rather than to preservation. Suggestion during questioning introduces details that become part of the memory, which has been demonstrated experimentally including the implanting of entire events that never happened. None of this means memory is generally unreliable, since it works well enough for ordinary purposes, and it does mean confidence is a poor guide to accuracy.
Why it matters
The separation of confidence from accuracy has consequences well outside the laboratory. Eyewitness testimony is evaluated by juries substantially on how confident the witness appears, and research consistently finds that confidence predicts accuracy weakly, particularly after a witness has been exposed to feedback or has repeated an account several times, which happens routinely before a trial. Clinical and historical testimony faces the same issue. The finding also bears on how people assess their own memories, since the intuition that a vivid memory is a reliable one is precisely what the research contradicts, and that intuition is difficult to shake even in people who know the evidence. The practical implications are for institutions rather than individuals, since the useful responses involve recording accounts early and avoiding procedures that inflate confidence without improving accuracy.
The takeaway
Memories of learning shocking news feel vivid and certain, and studies collecting accounts immediately and again years later find substantial change with confidence intact. Vividness tracks how often a memory has been rehearsed rather than how faithful it is, and each recollection reconstructs rather than retrieves. Juries assess eyewitnesses largely on confidence, which predicts accuracy weakly.
