I was actually just thinking about bringing that up in the open thread. Is there a preferred term for the philosophy characteristic of LW? "Rationalism" does indeed have too many irrelevant associations, from the old-timey Platonic philosophy that we can get useful information about the universe without studying the universe, to the philosophy termed "Traditional Rationality" around here (not sure exactly what defines that, but I have a general sense), to those people who spend a lot of time on reversed stupidity.

If making up a new term is okay (assuming there isn't a preferred term already), I might suggest "neo-rationalism". That way, people will know right away that it has something to do with rationality, but they will have to ask what the "neo-" signifies instead of jumping to any conclusions about it.
