In this episode I talk with Professor Maryanne Garry at the University of Waikato New Zealand about several interrelated realms of human cognition that are fundamental to changes in the behaviors of individuals and social groups as influenced by electronic media and artificial intelligence. Dr. Garry has devoted her career to understanding how memories of one’s past experiences can be distorted, how false information can become engrained in one’s system of beliefs. She talks about individual and collective memories, and the brain’s source monitoring systems and how they are influenced by group identity, repetition of information (whether true or not). Interestingly although memories of untruths can be retracted when new information is provided they can still influence one’s decision-making. She also talks about how social media and AI (LLMs) influence the brain’s source monitoring systems and potential approaches to ameliorating their adverse effects on mental health and societal discord.
