Invisibilia

Invisibilia, a show about the invisible forces that shape human behavior, weaves personal stories with scientific research that will ultimately make you see your own life differently.

A podcast BONUS for you today. We didn't have enough room in our Batman show for this lovely story about Julee-anne Bell, one of the many people who have learned Daniel Kish's echolocation technique. Enjoy!

The Power Of Categories examines how categories define us — how, if given a chance, humans will jump into one category or another. People need them, want them. The show looks at what categories provide for us, and you'll hear about a person caught between categories in a way that will surprise you. Plus, a trip to a retirement community designed to help seniors revisit a long-missed category.

Alix and Lulu present a bonus podcast about why "Inside Out" was considered as a possible name for the show, but ultimately wasn't chosen.

Co-hosts Alix Spiegel and Lulu Miller ask, "Are my thoughts related to my inner wishes, do they reveal who I really am?" The answer can have profound consequences for your life.

In "Fearless," co-hosts Alix Spiegel and Lulu Miller explore what would happen if you could disappear fear. A group of scientists believe that people no longer need fear — at least not the kind we live with — to navigate the modern world. We'll hear about the striking (and rare) case of a woman with no fear. The second half of the show explores how the rest of us might "turn off" fear.

In "How to Become Batman," Alix and Lulu examine the surprising effect that our expectations can have on the people around us. You'll hear how people's expectations can influence how well a rat runs a maze. Plus, the story of a man who is blind and says expectations have helped him see. Yes. See. This journey is not without skeptics.

In Entanglement, you'll meet a woman with Mirror Touch Synesthesia who can physically feel what she sees others feeling. And an exploration of the ways in which all of us are connected — more literally than you might realize. The hour will start with physics and end with a conversation with comedian Maria Bamford and her mother. They discuss what it's like to be entangled through impersonation.

In Our Computers, Ourselves, a look at the ways technology affects us, and the main question is : Are computers changing human character? You'll hear from cyborgs, bullies, neuroscientists and police chiefs about whether our closeness with computers is changing us as a species.
