The trolley problem has no right answer

The Trolley Problem is philosophy's most famous ethical dilemma: should you divert a runaway trolley to kill one person instead of five? Most people say yes, but a twist reveals our true ethics. If you must push a large person off a bridge to save five, most refuse, despite the identical "math." This shows we don't just apply pure logic. We distinguish between action and inaction, and using people as means versus side effects. This thought experiment is now urgent for programming self-driving cars.
