Perhaps you've heard of the so-called trolley problem, also known as the train problem. The old philosophical question goes like this:
There is a trolley barreling down the tracks. Ahead, on the tracks, there are five people tied up and unable to move. The trolley is headed straight for them. You are standing next to a lever. If you pull this lever, the trolley will switch to a different set of tracks, therefore saving the five people. However, you notice that there is one person on the side track. You have two options:
- Do nothing and allow the trolley to kill the five people on the main track.
- Pull the lever, diverting the trolley onto the side track where it will kill one person.
What is the right thing to do?
