Although the consensus seems to be that this post by PhilGoetz is an unhelpful, uninformed one, I believe I got something out of it:

1) I had never before even realized the similarity between Newcomb's problem and revenge. Sorry. bows head

2) It suggests to me a better way to phrase the problem:

a) Replace Omega with "someone who's really good at reading people" and give example of how she (makes more sense as a she) caught people in lies based on subtle facial expressions, etc.

b) Restate the question as "Are you the sort of person who would one-box?" Or "Do/should you make it a habit of one-boxing in cases like this?" rather than "Would you one-box?" This subtle difference is important.

If the above is all obvious, it's because I've done a poor job following the Newcomb threads, as many here seem to think Phil did, since they didn't interest me.
