The Trolley Problem and Its Variants
Quick fact
Most people say yes to pulling the lever but no to pushing the man, even though both actions save five lives at the cost of one—revealing a deep puzzle about moral intuition.
Why this is interesting
Imagine a runaway trolley is about to kill five people. You can pull a lever to divert it onto a side track, but that path has one person on it. Would you pull the lever? Now imagine you could push a fat man off a bridge to stop the trolley—would you do that instead?
