Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our “experiencing selves” and our “remembering selves” perceive happiness differently. This new insight has profound implications for economics, public policy — and our own self-awareness.
Widely regarded as the world’s most influential living psychologist, Daniel Kahneman won the Nobel Prize in Economics for his pioneering work in behavioral economics — exploring the irrational ways we make decisions about risk.
Why you should listen
Daniel Kahneman is an eminence grise for the Freakonomics crowd. In the mid-1970s, with his collaborator Amos Tversky, he was among the first academics to pick apart exactly why we make “wrong” decisions.
In their 1979 paper on prospect theory, Kahneman and Tversky examined a simple problem of economic risk. And rather than stating the optimal, rational answer, as an economist of the time might have, they quantified how most real people, consistently, make a less-rational choice.
Their work treated economics not as a perfect or self-correcting machine, but as a system prey to quirks of human perception. The field of behavioral economics was born.
Kahneman was awarded the Nobel Memorial prize in 2002 for his work with Tversky, who died before the award was bestowed. In a lovely passage in his Nobel biography, Kahneman looks back on his deep collaboration with Tversky and calls for a new form of academic cooperation, marked not by turf battles but by “adversarial collaboration,” a good-faith effort by unlike minds to conduct joint research, critiquing each other in the service of an ideal of truth to which both can contribute.
What others say
“Amos and I shared the wonder of together owning a goose that could lay golden eggs — a joint mind that was better than our separate minds.” — Daniel Kahneman
