In my experience, Cluster B personality disorders are not hereditary in the genetic sense but are hereditary in a learned sense. In other words, cluster B personality disorders usually develop because of nurture factors vs. nature factors. It’s extremely common for a cluster B to have a parent or parents that also meet the criteria for a personality disorder. Children learn how the world works mostly from their parents and are likely to adopt the same attitudes and relationship styles as their parents. Often, the environment isn’t validating or caring; it lacks empathy. When a child lacks a nurturing or caring parent, a personality disorder can easily develop. Children and teenagers are extremely egocentric and have difficulty seeing things through another person’s point of view but this is mostly because their brain is underdeveloped and lacks the ability. Many people become arrested in this stage and don’t successfully advance from it when they become an adult. It’s also common for personality disorders to develop from childhood trauma and/or a lack of positive attachment to happen within the home.
