I have always considered Scott Aaronson the least bad of the big-name rationalists. Which makes it slightly funny that he didn't realize he was one until Scott Siskind told him he was.
Unfortunately it didn't a lot of traction and dang told me that there wasn't a way to re-up or "second chance" the post due to the HN policy on posts "correlated with political conflict".
However, reading this article about all these people at their "Galt's Gultch", I thought — "oh, I guess he's a rhinoceros now"

Here's a bad joke for you all — What's the difference between a "rationalist" and "rationalizer"? Only the incentives.
