#1
S2E1 8.9
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.

#2
S2E8 8.9
The Electric Brain

Our nervous system is fundamentally electric. We move our arm by sending a signal to the muscles that control it. That means we can bypass our brains and use electricity to control our bodies, or use our minds to control other bodies. In this episode, I explore how we can use electricity and our brains to control cockroaches, move other people’s limbs, restore motion to people who are paralyzed, and even read people’s minds.

#3
S2E7 8.7
Divergent Minds

Scientists can’t dissect living people’s brains to study their function. But by examining the behavior of people whose brains are atypical (due to stroke, injury, or being born that way), we can learn a lot about all our brains. In this episode, I travel to London to meet a blind, autistic savant with astonishing musical abilities, and I volunteer to have my own brain’s function temporarily disrupted at UCLA’s Neuromodulation Lab.

Lowlights

#25 S3E4 The Stanford Prison Experiment 7.3

Normal people can become monsters, given the right situation. That’s the standard narrative of the Stanford Prison Experiment, one of the most famous psychological experiments of all time. But what if the cause of its participants’ cruel behavior wasn’t what we’ve always been told?

#24 Artificial Intelligence S1E4 7.4
#23 Behaviour and Belief S3E7 7.5
#22 Moral Licensing S3E2 7.5
#21 Mind Reading S3E8 7.6
