单集简介 ...

Disgust is a strong emotion, one designed by evolution to protect us from danger and diseases. But disgust also spills into other areas of our lives, influencing our morals, our intuitions about right and wrong, even our politics. We talk with psychologist David Pizarro about how disgust is used to persuade and divide us, and why it remains such a potent force in public life today. Then, in our latest installment of “Your Questions Answered,” Huggy Rao returns to respond to listeners’ thoughts and questions about why big ideas fail. There's still time to join Shankar at one of our upcoming stops on Hidden Brain's live tour! Join us in Philadelphia on March 21 or New York City on March 25. And stay tuned for more tour dates to be announced soon!  Illustration by Alvaro Montoro for Unsplash Hosted by Simplecast, an AdsWizz company.

  • This is Hidden Brain.

  • I'm Shankar Vedanta.

  • When David Pizarro was five years old, he was at a weekly church meeting with his family.

  • The grown-ups went to visit with each other while the children,

  • including David, were left to their own devices.

  • And my sister and her little friend thought that they would play a fun game with me.

  • And that game involved making me lie down, close my eyes and open my mouth.

  • They wouldn't tell David what was going to happen.

  • It was to be a surprise I sort of naively trusting of my my dear older sister who by the way is an attorney now sure enough closed my eyes and opened my mouth and I felt something soft wet and sort of cold in my mouth and I immediately spit open my eyes and I saw my sister and her little friend laughing

  • If you're eating something right now,

  • I'd advise you to put it down.

  • What they had put in my mouth was, I don't recall exactly what food it was,

  • but it was partially chewed food that the other little girl had decided to chew up,

  • put in her hand, and then stick right in my mouth.

  • David's sister and her friend thought the whole thing was hilarious.

  • I've never felt so betrayed.

  • This is one of the key moments in my life where I was so disgusted.

  • I don't remember throwing up, but I can tell you for sure that I felt like throwing up.

  • And I to this day can remember the texture, the temperature, the feeling of that food in my mouth.

  • Wow.
