The Trolley & The Footbridge
Five Lives vs. One Life Pushed by Your Own Hands
A runaway trolley is hurtling toward 5 workers tied to the tracks. You are standing on a footbridge next to a large stranger. If you push him off the bridge onto the tracks, his body will stop the trolley and save all 5 people—but he will die.
The Survival Lottery
Perfect Fairness & Mandatory Sacrifice
Every citizen is assigned a number. Whenever 5 patients need heart, lung, kidney, and liver transplants to survive, a computer runs a strictly fair lottery to pick 1 healthy citizen, who is painlessly euthanized so all 5 patients live.
The Ship of Theseus

The Benevolent Lie to a Murderer
Absolute Honesty vs. A Lie to Save a Friend
