Thought experiment

Thought experiment

The purpose of the thought experiment is to delve deeper into a given field to improve your knowledge, uncover what you don't know, and strengthen your understanding of the world.

For example, a madman has tied 5 innocent people to a trolley track. An empty trolley car is fastly approaching the people. You can pull a lever and divert the trolley to another track, but there is 1 person tied to the other track. What would you do?

The idea is to uncover what you actively think about the situation.
