Daniel Kahneman was a brilliant scientist who marvelled at his own errors in thinking. “The essence of intuitive heuristics: when faced with a difficult question, we often answer an easier one instead, usually without noticing the substitution”, he wrote in Thinking, Fast and Slow.

I first met Danny when I was a student at Stanford, working in the laboratory of his longtime collaborator Amos Tversky. Danny worked across the bay at University of California, Berkeley, and he and Amos alternated visits on a regular basis, just as they alternated authorship on their papers. It was Danny’s turn to come to Stanford.
