The Undoing Project
A Friendship that Changed the World
Danny and Amos had been at the University of Michigan at the same time for six months, but their paths seldom crossed; their minds, never. Danny had been in one building, studying people’s pupils, and Amos had been in another, devising mathematical approaches to similarity, measurement, and decision making.
“We had not had much to do with each other,” said Danny. The dozen or so graduate students in Danny’s seminar at Hebrew University were all surprised when, in the spring of 1969, Amos turned up. Danny never had guests: The seminar was his show. Amos was about as far removed from the real-world problems in Applications of Psychology as a psychologist could be. Plus, the two men didn’t seem to mix. “It was the graduate students’ perception that Danny and Amos had some sort of rivalry,” said one of the students in the seminar. “They were clearly the stars of the department who somehow or other hadn’t gotten in sync.”
Before he left for North Carolina, Amnon Rapoport had felt that he and Amos disturbed Danny in some way that was hard to pin down. “We thought he was afraid of us or something,” said Amnon. “Suspicious of us.” For his part, Danny said he’d simply been curious about Amos Tversky. “I think I wanted a chance to know him better,” he said.
Danny invited Amos to come to his seminar to talk about whatever he wanted to talk about. He was a little surprised that Amos didn’t talk about his own work—but then Amos’s work was so abstract and theoretical that he probably decided it had no place in the seminar. Those who stopped to think about it found it odd that Amos’s work betrayed so little interest in the real world, when Amos was so intimately and endlessly engaged with that world, and how, conversely, Danny’s work was consumed by real-world problems, even as he kept other people at a distance.
Amos was now what people referred to, a bit confusingly, as a “mathematical psychologist.” Nonmathematical psychologists, like Danny, quietly viewed much of mathematical psychology as a series of pointless exercises conducted by people who were using their ability to do math as camou?age for how little of psychological interest they had to say. Mathematical psychologists, for their part, tended to view nonmathematical psychologists as simply too stupid to understand the importance of what they were saying. Amos was then at work with a team of mathematically gifted American academics on what would become a three-volume, molasses-dense, axiom-?lled textbook called Foundations of Measurement—more than a thousand pages of arguments and proofs of how to measure stuff. On the one hand, it was a wildly impressive display of pure thought; on the other, the whole enterprise had a treefell-in-the-woods quality to it. How important could the sound it made be, if no one was able to hear it?
If you had visited the quaint English village of Great Rollright in 1945, you might have spotted a thin, dark-haired and unusually elegant woman emerging from a stone farmhouse called The Firs and climbing onto her bicycle.
I heard them long before I saw them, the throaty rumble of their Second World War engines reverberating in my hearing aids as I sat outside on the morning of my 100th birthday.
Melbourne, 1912: on the busy corner of Collins and Swanston streets stood an attractive woman of middle age.
The frail old man wakes screaming, tangled in an American flag—the same one that draped the coffin of his slain son, President John Fitzgerald Kennedy, three days after his November 22, 1963, assassination.
In June 1885, three Frenchmen arrived in London. One was a Prince, one was a Count, and the third was a commoner with an Italian surname.
The best-known modern Chinese ‘fairy tale’ is the story of three sisters from Shanghai, born in the last years of the nineteenth century.
Young people around the world are cracking open the heart of the climate crisis, speaking of a deep longing for a future they thought they had but that is disappearing with each day that adults fail to act on the reality that we are in an emergency.
So many people ask me, with love and kindness in their hearts, “What has been your proudest moment, Ziauddin?”
