Levers and dilemmas: pull the lever — 5 friends saved, 1 stranger sacrificed. Pull or not?
The runaway cart: 5 friends tied on the main track. On the side track: 1 stranger (someone nobody here knows).
The cart won't stop in time. You're standing by the lever. Pull = cart swerves to the side track and hits the 1 instead of the 5.
Each person votes first: pull or don't pull — no changing after hearing others.
Then the hard part: explain why in one sentence.
Twist round: the 5 are strangers and the 1 is a friend. Does anyone's vote flip?
There's no clean answer — your reasoning is the content
This is the trolley problem, invented by philosopher Philippa Foot in 1967 — and 60 years of arguing has produced no correct answer. Two instincts fight: numbers (5 lives are more than 1 — pull) versus the line you don't cross (the lever makes the 1 stranger's death something you did, not something that happened).
Notice what your family actually did: most voted pull, most wouldn't push a big stranger off a bridge to get the same 5 saved — same maths, different feeling. That gap is the whole lesson. Dilemmas are designed to have no clean answer; how you argue is the content.
