Memory conformity for confidently recognized items: The power of social influence on memory reports

Memory conformity occurs when one personʹs memory report influences anotherʹs. Memory conformity is more likely to occur when the information comes from a credible source, and when internal evidence is weak. Here, we investigate whether there are situational variations in how heavily participants weigh internal cues to accuracy when confronted with conflicting information from a partner. The results show that even confidently held memories are subject to influence from external sources, and that social influence is exaggerated when the source is seen to be highly credible.
