AI-generated summaries can manipulate memories, study says
A study from Georgetown University and the University of Washington suggests that AI-generated summaries often omit critical information and can manipulate human memory. Researchers found that participants were significantly more likely to recall events incorrectly after reading misleading AI summaries.
