Imagination Inflation
Imagination inflation is an increase in confidence that a past event occurred after imagining that event. Researchers compare judgments before and after an imagination exercise, using suitable controls. Increased confidence is not necessarily a detailed memory, and the finding does not mean that imagining any event will make someone remember it as real.

Evidence for the claims on this page: Experimental evidence within defined tasks
The cited study measures confidence that childhood events occurred. Increased confidence is not the same outcome as a detailed recollection.
How to read this assessmentWhat it is
Imagination inflation refers to higher retrospective likelihood or confidence ratings following an imagination exercise. It is studied by comparing judgments before and after imagining an event, with suitable control conditions. (Garry et al., 1996)
In everyday language
Imagining an event can sometimes make it seem more familiar and more likely to have happened. Increased confidence does not necessarily mean someone has developed a detailed memory of it.
What it isn't
It does not mean that imagination inevitably creates false memories. Confidence, belief that an event occurred, and a feeling of remembering are different outcomes.
An example
Hypothetical example: after imagining a childhood visit to an unfamiliar aquarium, a person becomes more confident that the visit happened, despite having no new evidence.
Key features
- Follows imagining an event
- Typically concerns confidence or judged likelihood
- Must be distinguished from a vivid recollective experience
How it relates to synthetic imprinting
It suggests questions about guided imagination involving synthetic scenes. Viewing generated media and imagining an event are different tasks and should not be treated as interchangeable.
Research context
Garry and colleagues found increased confidence after participants imagined selected childhood events. Their study supports a particular experimental effect, not a general claim that fictional experiences become autobiographical memories. (Garry et al., 1996)
