In this WNYC All of It segment, host Alison Stewart welcomes Shankar Vedantam, host and executive editor of the podcast Hidden Brain, to discuss recent episodes that explore why people lie, keep secrets, and the consequences of both secrecy and transparency. Vedantam explains Hidden Brain’s mission to make listeners "tourists in their own minds," using social‑science research to reveal hidden mental processes. The conversation covers the basic motivations for secret‑keeping—fear of judgment, shame, and the brain’s capacity to hold contradictory versions of truth— and the psychological benefits of oversharing, such as increased authenticity, the pratfall effect, and stronger social bonds. They examine moral complexities when honesty conflicts with compassion, illustrated by a dementia‑care scenario and the trade‑off between virtues. Research findings are highlighted, including Emma Levine’s work on the limits of truth‑telling, Leslie John’s studies on preferences for confession versus silence, and a striking statistic that 80 % of patients lie to doctors. The discussion also touches on how people are more willing to be transparent with AI chatbots, the distortion created by social‑media portrayals of perfect lives, and a "CV of failures" experiment that reframes failure as normal. Listener call‑ins provide real‑world examples of lying, secret‑keeping, and coming clean, revealing the emotional weight of shame and the relief of honesty. The segment ends with a preview of upcoming Hidden Brain topics, including new perspectives on depression.
