This week's episode of Hidden Brain explores the psychological impact of feeling overlooked and unvalued. Psychologist Gordon Flett discusses how a lack of "mattering" can lead to loneliness, depression, and potentially even violence. Feeling valued acts as a psychological buffer, protecting against these negative effects. Simple gestures can help rebuild a sense of meaning and belonging for oneself and others. The episode also features listeners' experiences with finding healing in nature. Psychologist Marc Berman answers questions in the "Your Questions Answered" segment. The episode's content touches on sensitive topics such as loneliness, depression, and suicide, offering resources for help. Shankar will be presenting psychological insights from the show's first decade on the Hidden Brain live tour in Philadelphia and New York City. The show is produced by Simplecast, an AdsWizz company.
