BEHAVIOR expert: the SECRETS of the HUMAN MIND.

"Lie detection doesn't exist." So says a former member of the UCO, the Guardia Civil's elite investigative unit, who has had to negotiate from the trunk of a car. Juanma García Pincho has spent years sitting across from kidnappers, murderers and people on the verge of taking their own lives. On No me hables de tu libro, the unfiltered podcast hosted by Álvaro Barrera and Carlos Montojo, he explains how interrogations really work, why the polygraph is useless and which gesture led him to find a hidden weapon. He also explains how to spot a narcissist, why there are more psychopaths in the executive offices than on the shop floor, and what to do if someone is following you at night. And he shares the signs almost nobody notices when a person is thinking about taking their own life. — Guardia Civil interrogations: what they're really like and why Hollywood gets it wrong — Kidnap negotiation and negotiating when there's a victim involved — Body language: the case of the weapon given away by a gesture — Polygraphs and lie detection: why they don't work — First impressions and body language in a job interview — Personal SWOT analysis: how to uncover your weaknesses — Techniques for getting information without asking questions — Integrated psychopaths and narcissists: how to identify them — Personal safety: how to tell if you're being followed and how criminals pick their victims — Political communication: Pedro Sánchez, Javier Milei, Donald Trump and the Spanish Royal Household — Suicide prevention: warning signs and how to help — His book "Ciencias del Comportamiento"
