A person is repeatedly given the option to increase his torture level by an undetectable increment, in exchange for $10,000. Each time, it seems rational to accept, but the end result is a life of agony that seems not worth the financial reward. The solution is to recognize that there can be an introspectively undetectable increment in pain, and that an undetectable harm can outweigh a detectable benefit.
