Should you tell a harsh truth if it will only cause pain? Or is it sometimes kinder to keep someone in the dark? Psychologist Emma Levine explores the unwritten rules that guide when people feel it’s acceptable to lie — and what those choices reveal about trust, harm, and our deepest moral values. In our companion Hidden Brain+ episode, we explore ways to bridge the gap between the many lies we condone in practice, and the lying we claim to hate. If you're a subscriber, that episode is called “Telling The Truth About Lies.” If you're not yet a Hidden Brain+ subscriber, please visit support.hiddenbrain.org or apple.co/hidden brain for a free seven-day trial.

We tend to see depression as an illness to eliminate, evidence that something has gone wrong in the brain. But what if low mood serves a purpose? Psychologist Jonathan Rottenberg examines the evolutionary roots of depression and reflects on his own painful experience with suicidal despair. He explores how depression can narrow our focus, and sometimes open the door to change. A note that this story includes a discussion of suicide. If you or someone you love is struggling with thoughts of suicide, there are people who can help. If you're inside the U.S., call or text 988, or visit the 988 Helpline online. If you’re outside the U.S., you can search for resources in your country on this site. Episode illustration by Runend Art for Unsplash Hosted by Simplecast, an AdsWizz company.

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.
