OK. He should solve the meta-puzzle first. "What is this likely to be, and in what proportion of possible worlds is the outcome of knowing the answer to that question good for me."
I agree. A lot of problems that afflict innocent people in our society can be chalked up to not doing that kind of higher-level thinking - what would be a person's possible motives for setting up this scenario? What are the potential consequences? Am I risking my finances, health, or livelihood by getting involved?
