100. Could Your Cheater Have a Personality Disorder? An Interview with Dr. Peter Salerno

100. Could Your Cheater Have a Personality Disorder? An Interview with Dr. Peter Salerno

Tracy talks with pyschologist Dr. Peter Salerno about the intersection of infidelity and personality disorders. A lot of conventional therapy assumes that clients lack insight into their behavior and that antisocial behavior is the result of childhood trauma. Dr. Salerno argues that this approach ignores the behavioral science of personality disorders. Manipulation, deception, and a pathological lack of remorse are hallmarks of narcissism and sociopathy and these abusive acts are intentional. And to a certain extent, even hard-wired. 

How does this science challenge the victim-blaming narratives around infidelity? Could the serial cheater, family abandoner, or deadbeat parent have a personality disorder? Do these manipulative characters keep you confused and hopeful on purpose
