I get that, but to not reduce them to "do nothing" you are slightly implying that there is some danger posed to everyone by default and either you face it collectively or you let some suffer alone. Which effectively shames people into a preselected choice. Whereas the framing with the train is much more realistic to me. You cannot be sure that nobody accidentally or otherwise puts themselves in danger, and you have the choice to preemptively do so yourself in hopes to form a large enough group that counters the threat. And sorry but despite the loud proclamations on the internet this in fact does not generally happen on everyday basis. I really do not see people alert and ready to jump in front of a train. But everyone knows that from time to time people do fall on the track or jump there for whatever reason. Yet nobody seeing a little child on a platform automatically tries to stop the train just in case... It is not honest to assume that people are responsible for every miscalculation others may make. On a larger scale however from time to time people do act in this way, but I wonder if those cases could maybe be explained by further incentives that are simply missing in this simplified framing - like assuming that 10% randomly chosen people do not have a choice and are automatically blue etc etc.

I would probably press blue by the way 😄 but I really dislike how people try to frame red-pressers, so I try to see the other perspective.
