Radio Replay: Yum and Yuck
Paul Rozin has been studying the psychology and culture of food for more than 40 years. And he's come to appreciate that food fills many of our needs, but hunger is just one. On this week's Radio Replay, we chew over the profound role that food plays in our lives. Then, we spit it all out — we study the ick factor that turns us off to cockroaches, skunks, and poop. Rachel Herz explains the sensation of disgust, and why it doesn't always come naturally. For more information about the research in this episode, visit https://n.pr/2UTf1p0.

Spoiler Alert! The Psychology Of Surprise Endings
Why do we always fall for surprise endings? It turns out that our capacity to be easily fooled in books and movies is made possible by a handful of predictable mental shortcuts. We talk this week with Vera Tobin, one of the world's first cognitive scientists to study plot twists.
