Social perceptions of misinformation sources and memory

Area of Science:

• Cognitive Psychology
• Social Psychology
• Memory Research

Background:

• The misinformation effect demonstrates that memory can be altered by post-event information.
• Individuals actively evaluate sources of information, rather than passively accepting misinformation.
• The influence of source perception on susceptibility to misinformation remains underexplored.

Purpose of the Study:

• To investigate the relationship between social perceptions of misinformation sources and susceptibility to post-event misinformation.
• To examine how different types of misinformation (explicit vs. pragmatic implication) affect source perception and memory accuracy.
• To provide novel insights into the cognitive and social factors influencing memory distortions.

Main Methods:

• Three preregistered studies were conducted involving participants learning a narrative.
• Participants answered questions under neutral, explicit misinformation, or pragmatic implication misinformation conditions.
• Social perceptions of interviewers (competence, sociability, morality) and memory accuracy were assessed.

Main Results:

• Sources presenting explicit misinformation received lower social perception ratings compared to neutral or pragmatic implication conditions.
• Social perception ratings of the sources were not correlated with participants' memory accuracy.
• Exposure to misinformation, irrespective of its type, increased the occurrence of misinformation errors.

Conclusions:

• While individuals form social judgments about misinformation sources, these perceptions do not mitigate memory inaccuracies.
• Misinformation exposure consistently leads to memory errors, highlighting the robustness of the misinformation effect.
• Future research should explore interventions that target source evaluation to potentially reduce memory distortions.
