For Robin’s statistics:
Given no other data but the choice, I would have to choose torture. If we don’t know anything about the consequences of the blinking or how many times the choice is being made, we can’t know that we are not causing huge amounts of harm. If the question deliberately eliminated these unknowns- ie the badness was limited to an eyeblink that does not immediately result in some disaster for someone or blindness for another, and you really are the one and only person making the choice ever, then I’d go with the dust—But these qualifications are huge when you consider 3^^^3. How can we say the eyeblink didn’t distract a surgeon and cause a slip of his knife? Given enough trials, something like that is bound to happen.
