Evidential Decision Theory and Mass Mind Control

You've probably read about evidential decision theory in another post.

Let me begin with something similar to Newcomb's paradox. You're not the guy choosing whether or not to take both boxes. You're the guy who predicts. You're not actually prescient. You can only make an educated guess.

You watch the first person play. Let's say they pick one box. You know they're not an ordinary person. They're a lot more philosophical than normal. But that doesn't mean that the knowledge of what they choose is completely useless later on. The later people might be just as weird. Or they might be normal, but they're not completely independent of this outlier. In short, you can use his decision to predict theirs, if only a little.

The decision of the player choosing the box effects whether or not the predictor will predict if later people take the box. Since the predictor is completely rational, this means that the player choosing the box effects decisions other people make.

In short, the decisions you make effect the decisions other people make. I'm not sure how much, but there have probably been 50 to 100 billion people. And that's not including the people who haven't been born yet. Even if you only change one in a thousand decisions, that's at least 50 million people.

Like I said: mass mind control. Use this power for good.
Consequentialism: The belief that doing the right thing makes the world a better place.

Intriguing suggestion, DanielLC! Gary Drescher discusses issues like this in his Good and Real. I wonder if there's also discussion of it somewhere on LessWrong?
