As it happens, a perfect and truthful predictor has declared that you will choose torture iff you are alone.
OK. Then that means if I choose torture, I am alone. If I choose the dust specks, I am not alone. I don’t want to be tortured, and don’t really care about 3 ^^^ 3 people getting dust specks in their eyes, even if they’re all ‘perfect copies of me’. I am not a perfect utilitarian.
A perfect utilitarian would choose torture though, because one person getting tortured is technically not as bad from a utilitarian point of view as 3 ^^^ 3 dust specks in eyes.
This doesn’t seem very coherent.
