Nothing surprising ;-)

Nothing surprising?!!

8-) Don't say that too loudly, Yudkowsky might hear you. :-)

The article is a bit naughty when it says, of Tversky and Kahnemann, that "...this has become conventional wisdom among cognition researchers." Actually, the original facts were interpreted in a variety of ways, some of which strongly disagreed with T & K's original intepretation, just like this one you reference above. The only thing that is conventional wisdom is that the topic exists, and is the subject of dispute.

And, as many people know, I made the mistake of challenging Yudkowsky on precisely this subject back in 2006, when he wrote an essay strongly advocating T&K's original intepretation. Yudkowsky went completely berserk, accused me of being an idiot, having no brain, not reading any of the literature, never answering questions, and generally being something unspeakably worse than a slime-oozing crank. He literally wrote an essay denouncing me as equivalent to a flat-earth believing crackpot.

When I suggested that someone go check some of his ravings with an outside authority, he banned me from his discussion list.

Ah, such are the joys of being speaking truth to power(ful idiots).

As far as this research goes, it sits somewhere down at the lower end of the available theories. My friend Mike Oaksford in the UK has written several papers giving a higher level cognitive theory that says that people are, in fact, doing something like bayesian estimation when then make judgments. In fact, people are very good at being bayesians, contra the loud protests of the I Am A Bayesian Rationalist crowd, who think they were the first to do it.
