I must have missed that thread, thanks. Though I can't see why I'm wrong. It has nothing to do with frequentism vs. bayesianism (I'm a bayesian). It's simply that likelihood is relative to a model, whereas probability is not relative to anything (or, alternatively, is relative to everything), as they're saying in that thread. Through this interpretation it's easy to see why likelihood represents a degree of belief.

It's a quirk of the community, not an actual mistake on your part. LessWrong defines probability as Y, the statistics community defines probability as X. I would recommend lobbying the larger community to a use of the words consistent with the statistical definitions but shrug...

Okay, that clears up it up a lot.
