Isolation

What happens when your brain is deprived of stimulation? What effect does being cut off from interaction with the outside world have on a person? What effect does it have on me, when I am locked in a windowless, soundproof isolation chamber for three days? In this episode of Mind Field, I take both an objective and a very intimate look at Isolation.

The Greater Good

Would you reroute a train to run over one person to prevent it from running over five others? In the classic “Trolley Problem” survey, most people say they would. But I wanted to test what people would actually do in a real-life situation. In the world’s first realistic simulation of this controversial moral dilemma, unsuspecting subjects will be forced to make what they believe is a life-or-death decision.

Interrogation

Psychology. Neuroscience. Drugs. All can be tools of interrogation. In this episode, an expert shows me how to coerce unsuspecting subjects into signing false confessions; a police psychologist questions me about my personal life after I am injected with a truth serum; and I match wits against a new brainwave-reading lie-detection method developed at Northwestern University.

Your Brain on Tech

Technology isn’t just changing our lives. It’s literally changing our brains -- and maybe for the better. In this episode, I’m a human lab rat in a groundbreaking study at UC Irvine, where scientists test how playing 3D video games affects my spatial memory. Will 10 days of gaming improve my ability to physically navigate a giant, 60-foot maze? And will an fMRI machine detect any physical changes to my brain?

Moral Licensing

How are our moral decisions influenced by factors we’re not aware of? A phenomenon known as Moral Licensing claims that when we do something good, we often subconsciously allow ourselves to then do something bad. In this episode, I take a look at whether those who donate money to charity become more likely to let a kid take the blame for a crime they know they committed.

The Stilwell Brain

There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!

How to Talk to Aliens

Behaviour and Belief

How can a lie become true? In this episode, Dr. Aaron Blaisdell and I create a game show that is actually a giant “human Skinner Box” to observe the formation of superstitious beliefs. And Dr. Samuel Veissière helps me design and perform a placebo reverse exorcism, harnessing the power of belief in both science and religion to convince normal people that a spirit has possessed their bodies.
