Just as an experiment I challenge the reader to consider the well know trolley problem. Be honest to yourself. Make up a random man on the street. Name him Joe. Joe can save plenty of other people if you push him on the track. Imagine average Joe. Now wait 10 minutes, by the clock. Now imagine a random woman. Lets call her Jane.
Are you really going to tell me you aren’t seeing it there? Scurrying about in the dark back of your mind, registering on your warm fuzzy evaluation function, before you suppress it in shame or to win an argument. You would spend more time before pushing Jane compared to Joe and you know it. Ceteris paribus for some values of numbers of lives saved you might push Joe but not Jane.
This is a disturbingly effective demonstration.
