>But high IQ people can have bad beliefs and poor models. Without self-correction and a reality-testing loop they're just as likely to believe wrong and dangerous things. As likely, or even more likely. Experts on a subject can be those that get it wrong the most, especially (as you point out) in fields where there is no proper measurement apparatus to conduct reality checks (like psychology before neurosciences), because they are those that dig the most in possibly wrong directions. Reminds me of a quote: "The eminently false mind is the one who never feels that he is going astray." (Joseph Joubert) (original: "L'esprit éminemment faux est celui qui ne sent jamais qu'il s'égare.")
