Daniel Kahneman, co-winner of the 2002 Nobel Prize in economics, together with Vernon Smith, died right this moment. Right here’s his obit within the Washington Submit.

Right here’s his bio within the Concise Encyclopedia of Economics.

Right here’s an excerpt from the bio:

One bias they [Kahneman and Tversky] discovered is that individuals are likely to imagine in “the regulation of small numbers”; that’s, they have a tendency to generalize from small quantities of information. So, for instance, if a mutual fund supervisor has had three above-average years in a row, many individuals will conclude that the fund supervisor is healthier than common, although this conclusion doesn’t comply with from such a small quantity of information. Or if the primary 4 tosses of a coin give, say, three heads, many individuals will imagine that the subsequent toss is prone to be tails. Kahneman noticed this perception in his personal habits as a younger navy psychologist within the Israeli military. Tasked with evaluating candidates for officer coaching, he concluded {that a} candidate who carried out effectively on the battlefield or in coaching could be pretty much as good a frontrunner later as he confirmed himself to be through the statement interval. As Kahneman defined in his Nobel lecture, “As I understood clearly solely after I taught statistics some years later, the concept predictions must be much less excessive than the data on which they’re primarily based is deeply counterintuitive.”

Right here’s my favourite excerpt from the WaPo obit:

Throughout World Battle II, he was pressured to put on a Star of David after Nazi German forces occupied town in 1940. One night time in 1941 or ’42, he later recalled, he stayed out previous the German-imposed curfew for Jews whereas visiting a good friend, and he turned his sweater inside out to cover the star whereas he walked a number of blocks residence. He then crossed paths with a soldier within the SS, who referred to as him over, picked him up — and hugged him.

“I used to be terrified that he would discover the star inside my sweater,” Dr. Kahneman famous in a biographical essay for the Nobel Prize ceremonies. However the German pulled out his pockets, confirmed him a photograph of a boy, gave him some cash and despatched him on his means. “I went residence extra sure than ever that my mom was proper: folks had been endlessly sophisticated and attention-grabbing.”

My favourite work of his is Considering, Quick and Gradual. I examine half of it on a flight from San Francisco to Seoul simply after it got here out and was so enthusiastic about his distinction between System 1 (quick) and System 2 (gradual) considering that I needed to share it with my seat mates. Sadly, they didn’t converse English. I found out that from a really early age I’ve been primarily a System 2 thinker. After having honed the talent for many years, although, I do it pretty quick.

Right here’s former co-blogger Bryan Caplan’s Eureka second the place he makes use of a Kahneman perception to clarify why folks typically go unsuitable in enthusiastic about economics and financial coverage.
