“It is useful to remember, however, that neglecting valid stereotypes inevitably results in suboptimal judgments. Resistance to stereotyping is a laudable moral position, but the simplistic idea that the resistance is costles is wrong. The costs are worth paying to achieve a better society, but denying that the costs exist, while satisfying to the soul and politically correct, is no scientifically defensible.”

“It seems reasonable to say that people make good choices in contexts in which they have experience, god information, and prompt feedback - say, choosing among ice cream flavors. People know whether they like chocolate, vanilla, coffee, licorice, or something else. They do less well in contexts in which they are inexperienced and poorly informed, and in which feedback is slow or infrequent - say, in choosing between fruit and ice cream (where the long-term effects are slow and feedback is poor) or in choosing among medical treatments or investment options. If you are given fifty prescription drug plans, with multiple and varying features, you might benefit from a little help. So long as people are not choosing perfectly, some changes in the choice architecture could make their lives go better (as judged by their own preferences, not those of some bureaucrat).”

“There is overwhelming evidence that obesity increases risks of heart disease and diabetes, frequently leading to premature death. It would be quite fantastic to suggest that everyone is choosing the right diet, or a diet that is preferable to what might be produced with a few nudges. Of course, sensible people care about the taste of food, not simply about health, and eating is a source of pleasure in and of itself. We do not claim that everyone who is overweight is necessarily failing to act rationally, but we do reject the claim that all or almost all Americans are choosing their diet optimally.”

“More generally, the financial benefits of self-employment are mediocre: given the same qualifications, people achieve higher average return by selling their skills to employers than by setting out on their own. The evidence suggests that optimism is widespread, stubborn, and costly. Psychologists have confirmed that most people genuinely believe they are superior to most others on most desirable traits - they are willing to bet small amounts of money on these beliefs in the laboratory.”
