Eyewitness memory can be inaccurate.
A sincere memory can contain errors. Perception, delay and later information can affect recall.
Show me why
Memory is not a permanent recording. Research on eyewitness identification shows limits in what people perceive, retain and later recognize. Accuracy varies with conditions and procedures.
A common misconception
Confidence or sincerity alone does not guarantee accuracy.
Where the limits are
This does not imply that every witness is wrong or that all testimony has equal reliability.
How we know
The National Research Council reviews laboratory and applied evidence. It describes how lighting, attention, memory processes and identification procedures can affect outcomes. Corroboration helps evaluate an account without assuming either perfect recall or dishonesty.
What would change this conclusion?
Better evidence can improve estimates for specific conditions and procedures; the existence of documented memory errors remains established.
