In this episode of Intelligence Matters, host Michael Morell speaks with Ursula Wilder, a clinical psychologist at the Central Intelligence Agency, about why intelligence agencies conduct psychological profiles of world leaders, and how past policymakers have used what they have learned to make strategic decisions. Wilder, who also worked in CIA's counterterrorism center and Medical and Psychological Assessments unit, explains the "dark tetrad" of personality -- narcissism, paranoia, Machiavellianism and sadism -- and how those traits can influence how leaders make decisions and engage in negotiations. She and Morell also discuss how policymakers respond to psychological profiles compiled by government agencies.
