Misinformation effect
Short answer

The misinformation effect is a well-replicated tendency for misleading post-event information to reduce accurate recall or become incorporated into reports of what happened. The central dispute is not whether misleading information can change responses, but whether it overwrites, blocks, blends with, or merely competes with the original memory—and how much reporting strategy contributes.
The views on this question
Two lenses on the same evidence. Source weight and the primary source ratio show what each rests on.
Alternative
Source weight 60%The dissenting account accepts that misinformation can change what people report, but challenges the strongest interpretation: that the original memory has been overwritten. It emphasizes limitations in standard testing, source confusion, task demands, and the possibility that people strategically report misleading details without a deep change in memory.
- McCloskey and Zaragoza argued that classic misinformation procedures do not establish impairment of the original memory and reported no effect under an alternative test procedure.
- Some apparent memory distortion may reflect source misattribution or integration of information from several sources rather than replacement of the original trace.
- Demand characteristics and strategic reporting remain possible explanations for at least some misinformation findings, making mechanism—not merely changed answers—the key dispute.
- The metaphor of misinformation as a contagious virus, and of resistance as a vaccine-like immunity, may oversimplify the psychological and social processes involved.
