Anecdotes
When the Nobel committee asked him what he would do with his prize of more than a million dollars in 2017, Richard Thaler answered with humor that he planned to spend it “in the most irrational way possible” — a perfect nod to his own theory about human decision-making.
Thaler keeps a list he calls “the anomalies cupboard”: economic behaviors that classical theory cannot explain. Instead of ignoring them as his colleagues did, he made them the heart of his entire research career.
In 2015, Richard Thaler appears in the film “The Big Short” about the 2008 financial crisis. Seated at a casino table beside the singer Selena Gomez, he explains the “hot hand bias” to the general public in person.
To illustrate one of his concepts, Thaler used to tell how he once refused to sell a bottle of wine bought for 10 dollars that had become very expensive, while also refusing to buy an identical one at that high price: living proof of “the endowment effect” he was studying.
Thaler liked to repeat a phrase that became famous: to truly understand economics, you have to accept that people are not “Econs” (perfectly rational beings) but “Humans” (humans full of flaws and emotions).
Primary Sources
A nudge is any aspect of the choice architecture that alters people's behavior in a predictable way without forbidding any options or significantly changing their economic incentives.
Ordinary people are not emotionless beings who calculate like computers and don't suffer from self-control problems. They are Humans.
To advance economic science, we must incorporate the fact that agents are human, with limited rationality and social preferences.
An anomaly is a fact that contradicts the predictions of standard economic theory; ignoring them does not make them go away.
