Humans Are Nicer Than We Think

I have always found the trolley model to be absurd. If we were being realistic, then there would be other solutions. The same dilemma was re-written for river tribesmen, and I much prefer this version. As far as I can remember, it goes like this...

You fish on the great river. There are five people in your boat: four people who row, and a fat guy who sits in the back and baits the hooks. Your grandfather has stories of a great and fierce crocodile that lives in the river, and kills entire boat crews, but your generation have never seen it...

(1)

The crocodile appears and comes for the boat. He swims much faster than you can row, but you start to row anyway. The fat guy was standing up at the back, and he falls in. Suddenly the boat is going faster: you might get to shore, but then the fat guy is lost. Do you turn around and try to pick him up? Most people would keep going, but feel that they ought to turn back.

(2)

The crocodile appears and comes for the boat. He swims much faster than you can row, but you start to row anyway. The fat guy was standing up at the back, but does not fall in. You know if he falls in, the boat will go faster, and he may distract the crocodile too. Do you push him in? Most people would not push, but would think that the four for one exchange is reasonable.

(3)

You are the fat guy. The crocodile appears and comes for the boat. If you jump off the boat, the others might make it to shore. Most people would think that the four for one exchange is reasonable: they hope they would be noble enough to jump, but suspect the wouldn't actually do it.
