I would say the direction I most dissent from Less Wrong is that I don't think 'rationality' is inherently anything worth having. It's not that I doubt its relevance for developing more accurate information, nor its potential efficacy in solving various problems, but if I have a rationalistic bent that is mainly because I'm just that sort of person - being irrational isn't 'bad', it's just - irrational.

I would say the sort of terms and arguments I most reject are those with normative-moral content, since (depending on your definition) I either do not believe in, or reject the relevance of, ethical propositions. Which in itself is the reason I reject 'rationality' as some high standard. I'm also basically disinterested in anything that happens after my death, and I doubt the efficacy of personal influence enough to view any attempts to reform other people (much less the planet) as a waste of time. In fact, I don't think I even have any particular attachment to 'humans-as-a-species'. If they can't adapt to reality, good riddance.
