Excuse me, but when our moral intuitions say that two things are
different, they usually are. If you shove a person in front of a trolley,
and he dies, and then it turns out that it was a false threat... well,
oops. If the switch is a false threat then flipping it does no damage.
Uncertainty about the outcome of actions is one of the foundations of
ethics, one of the environmental conditions to which moral intuitions are
an adaptation, and quite relevant here. How would this trolley-accident
scenario arise in real life, anyway?
