Is Gen Z truly the most self-obsessed generation, or are they just operating within the digital parameters they were given? In this episode of Untethered, Michelle and Serana look past the "selfie town" stereotypes to examine the underlying neuroscience and genetics of narcissism. Serana busts some of the biggest pop-psychology myths, explaining that Narcissistic Personality Disorder (NPD) has a relatively high genetic heritability rate and distinct physical markers in the brain, such as reduced gray matter in specific regions. They explore the differences between grandiose and vulnerable narcissistic personality disorder subtypes, dissect the "diathesis-stress model", and fact-check whether different cultureshave higher rates of individual vanity.
