The Diary Of A CEO with Steven Bartlett

Are you dealing with a master manipulator? Learn how to identify the hidden red flags of liars, psychopaths and narcissists before they cause lasting damage.

Dr. Leanne ten Brinke, a renowned psychologist and director of the Truth and Trust Lab at the University of British Columbia, breaks down the science of deception and toxic behavior. Drawing from her extensive peer-reviewed research and her eye-opening book, Poisonous People, she shares practical, evidence-based strategies to help you recognize dark personality traits and protect your mental well being.

In this episode, she explains:
■ The Warning Signs: How to spot the early behavioral red flags of the "Dark Tetrad" (psychopathy, narcissism, Machiavellianism, and sadism) before you get hurt.
■ The Manipulation Playbook: The exact psychological tactics toxic individuals use to control and deceive others, including what gaslighting actually means.
■ The Lie-Detector Myth: Why relying on eye contact, fidgeting, and body language is actually a terrible way to catch a liar.
■ The Two Faces of Narcissism: How to identify the different types (including why one completely crumbles at the slightest criticism), and the devastating toll of working for a psychopathic boss.
■ Defense Strategies: Proven techniques to outsmart dangerous personalities, set ironclad boundaries, and dramatically improve your life.
