Do you consider yourself a moral person? How would you act if you were presented with a situation where you were forced to make a difficult choice, where depending on what you decide, someone will die?
Time Magazine blog has a Morality Quiz, where you can compare your choices to those made by other readers. For instance, take this scenario:
Scenario 3a: The Trolley
An out of control trolley is heading down a track toward five unsuspecting people and will surely kill them all. You could throw a switch diverting it to a siding, but an equally unsuspecting man is standing there and the train will kill him instead. Could you throw the switch, killing one to save five?
