Robin's post seemed to be about the marginal value of rationality. Being completely irrational is a one way ticket to death or ruin, I agree. But there are fewer ways to die by refusing to go from ordinary high-IQ university-educated person to person who has read and applied the Overcoming Bias techniques. They're still there, but they're not quite as obvious. Most of the ones I can think of involve medicine, and Robin probably disagrees and doesn't think those matter so much.
