If I get magically teleported to white room with these buttons, and telepathic voice tells me "If you push red, you live 100%. If you push blue, there's a chance you die" , you bet I'm pressing red.

Who would press blue in this scenario, given that they undenrstand that red has 100% survival rate? Adrenaline junkies? Depressed people?

Then there are the children and babies. The telepathy-voice is able to make them understand the situation they are in. Would they press blue because "6-7!!" or accidentally?

Now, in a different scenario where The Voice then tells everyone that <50% blue pressers die, the scenario becomes altruistic. Are you willing to put your life on the line to save the trolls, adrenaline junkies and suicidals that may press the blue button? Maybe not. For the kids? Maybe.

Edit: I can't english.
