What does it mean 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.

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.

A more precise definition

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.

Key features

  • Follows imagining an event
  • Typically concerns confidence or judged likelihood
  • Must be distinguished from a vivid recollective experience

Where the definition stops

It does not mean that imagination inevitably creates false memories. Confidence, belief that an event occurred, and a feeling of remembering are different outcomes.

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.
