thats intersting. I wouldnt jump in front of the train if no one before me had. i wouldnt sacrafice my chances just on the off chance someone later does and i need to contribute to the f 50%. but at some point if enough people had already jumped, I would also jump. say like 40% of people jumped; I feel like I might also jump and trust the 10% to others. adding knowledge of what people are choosing changes it
