Is it rational to considers unknown possibilities and assigns gain to them and then decide, and if so what would be the numbers?

I think it still depends which school do you belong, Bayesian or frequentists. A real frequntist may not assign a probability to a single instance of society! he is either an engineer or not!

I think, when the money you may gain or lose goes way over your possible wealth you will start to think really non-linear (non-rational).

but I agree that people with same wealth level will weight risk factor differently ( in each gain or loss). in other words simple utility function is not enough!

Is it really possible to hack all these heavy files on super secret(isolated) computers from abroad?
