“Dawes observed that the complex statistical algorithm adds little or no value. One can do just as well by selecting a set of scores that have some validity for predicting the outcome and adjusting the values to make them comparable (by using standard scores or ranks). A formula that combines these predictors with equal weights is likely to be just as accurate in predicting new cases as the multiple-regression formula that was optimal in the original sample. More recent research went further: formulas that assign equal weights to all the predictors are often superior, because they are not affected by accidents of sampling.”

“We don't see very far in the future, we are very focused on one idea at a time, one problem at a time, and all these are incompatible with rationality as economic theory assumes it.”

“If people do not know what is going to make them better off or give them pleasure, then the idea that you can trust people to do what will give them pleasure becomes questionable.”

“You know, the standard state for people is 'mildly pleasant.' Negative emotions are quite rare, and extremely positive emotions are rare. But people are mildly pleased most of the time, they're mildly tired a lot of the time, and they wish they were somewhere else a substantial part of the time - but mostly they're mildly pleased.”

“It's a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.”

“People just hate the idea of losing. Any loss, even a small one, is just so terrible to contemplate that they compensate by buying insurance, including totally absurd policies like air travel.”

“It's clear that policymakers and economists are going to be interested in the measurement of well-being primarily as it correlates with health they also want to know whether researchers can validate subjective responses with physiological indices. ”

“Courage is willingness to take the risk once you know the odds. Optimistic overconfidence means you are taking the risk because you don't know the odds. It's a big difference.”

“True intuitive expertise is learned from prolonged experience with good feedback on mistakes.”

“By their very nature, heuristic shortcuts will produce biases, and that is true for both humans and artificial intelligence, but the heuristics of AI are not necessarily the human ones.”

“I used to hold a unitary view, in which I proposed that only experienced happiness matters, and that life satisfaction is a fallible estimate of true happiness.”
