Most people have an understanding of just how devastating social media and unrestrained access to technology have been to teens and young adults. What’s less understood is what the next threat is going to be to young people and their mental health. Evidence is mounting that it’s likely to be artificial intelligence and the very strange relationships people are starting to create with AI companions. People are using AI as their coaches, therapists, trusted friends, and even their romantic partners. According to Common Sense Media, more than half of American teens are using AI companions at least once a month. What’s forgotten is the deep, dark secrets being shared with AI companions are not protected or private. More concerning, many users lose touch with the fact that the AI companions are not real people. In this episode, Mandy McLean, CEO of ClassWaves, discusses what AI companions are, the risks they pose to users, why AI companions are appealing, and what parents and educators should be doing to avoid safety and manipulation risks AI companions introduce to students. Mandy says now is the perfect moment for AI companions to exponentially grow because of the loneliness epidemic, the amount of time people are spending using digital devices, and the quality of the AI companions in market. Mandy also discusses what is likely happening to the brains of children who frequently use AI companions. She talks about what happens to people who lose an “AI spouse” when outdated technology is sunset.

Living and working in groups is both a blessing and a curse. Too often, groups are in the news for all the wrong reasons: conformity, polarization, prejudice, conflict, and general mass stupidity. The secret is understanding how to work with the invisible forces of group dynamics instead of being mindlessly pushed around by them. In this interview, Dr. Colin Fisher shares his research on what leaders need to know and do in order to get their teams to perform up to their potential. He also shares how conformity can be used as an asset and competition can be detrimental to the way groups and teams operate. Because one of the methods of creating group cohesion is to create an “out” group, Dr. Fisher finishes with a conversation about ways in which the division plaguing many countries can be repaired.Dr. Fisher received his Ph.D. in Organizational Behavior from Harvard University, and previously worked as an Assistant Professor of Organizational Behavior at Boston University’s School of Management. Prior to his Ph.D. he studied improvisation in the arts at New York University (M.A.) and jazz trumpet at New England Conservatory of Music (B.Mus.).
