The Open Thread posted at the beginning of the month has gotten really, really big, so I've gone ahead and made another one. Post your new discussions here!

This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.

Yes, a CEV of only yourself is, by definition optimal.

The reason I don't recommend you try it is because it is infeasible; probability of success is very low, and by including a bunch of people who (you have good reason to think) are a lot like you, you will eventually reach the optimal point in the tradeoff between quality of outcome and probability of success.

I hope you realize that you are in flat disagreement with Eliezer about this. He explicitly affirmed that running CEV on himself alone, if he had the chance to do it, would be wrong.

"Low probability of success" should of course include game-theoretic considerations where people are more willing to help you if you give more weight to their preference (and should refuse to help you if you give them too little, even if it's much more than status quo, as in Ultimatum game). As a rule, in Ultimatum game you should give away more if you lose from giving it away less. When you lose value to other people in exchange to their help, having compatible preferences doesn't necessarily significantly alleviate this loss.
