Daniel Kahneman

Daniel Kahneman was born in 1934 in Tel Aviv. During his birth, there was no Israeli state; instead, the area had the name “Mandatory Palestine”, which was a region set by the League of Nations, after the fall of the Ottoman Empire.

His parents, though, were living in Paris, France, where Kahneman spent his childhood years. He later received his Ph.D. in psychology from the Hebrew University of Jerusalem in 1961.

He was the first who combined psychology and economics and thus creating the field of behavioral economics, which studies how people make economic decisions.

In 2002, Kahneman was awarded the Nobel Memorial Prize in Economic Sciences, along with his colleague Vernon Smith, for his work on behavioral economics. He has also received numerous other awards and honors, including the Presidential Medal of Freedom, which is the highest civilian award in the United States, and the Lifetime Achievement Award from the Society for Judgment and Decision Making.

Kahneman’s most famous book is “Thinking, Fast and Slow” which was published in 2011. The book summarizes research that he conducted over decades, with Amos Tversky, on the cognitive biases and heuristics that affect human decision-making.

In addition to his research and writing, Kahneman has also been a visiting professor at several universities, including the University of California, Berkeley, and the London School of Economics. He is a Fellow of the American Academy of Arts and Sciences and a Member of the National Academy of Sciences.
