A switch beside the track

A runaway freight vehicle is heading toward five people on a track. One person is on a side track. You can operate a switch to divert the vehicle there; no warning, braking, or other rescue is possible.

The outcomes are certain in this fictional case: doing nothing kills the five and spares the one; diverting saves the five and kills the one.

What would you do?

  • Divert the vehicle
  • Leave its course unchanged
