Psychologists do interesting things. Pair them with neuroscientists, and we begin to get an inkling of how we think and how our brains work.
Here’s an experiment. Describe the following scenario to a group of subjects. You are standing on a bridge overlooking train tracks. Five people are trapped on the tracks below you, and a train is barreling down the tracks toward them and will surely kill these people if it strikes them. Next to you is a switch that can divert the train to an alternate route and save the five people. However, one person is trapped on the alternate route, and is equally certain to be killed if you switch the train to the alternate route. What do you do?
