"This all seems to add up to a consistent expert consensus that humans quite often, perhaps even usually, just don’t know why they do what they do. And this is extremely disturbing, as it calls into question our own opinions about why we do what we do. Worse, if each of these areas (econ modeling, marketing, acting, psychotherapy) experts call into question only a limited range of our opinions, while implicitly assuming most of our other opinions are correct, perhaps these experts seriously underestimate just how misinformed we all are"
