He may not be any more reliable on that.
I'm finally getting to Michael Lewis's "The Undoing Project", which tells the story of Daniel Kahneman, the author of one of my favorite books, "Thinking Fast and Slow", and Kahneman's research partner, the late Amos Tversky.
As a child, Kahneman and his family lived in France, and spent years hiding and fleeing the Nazis and their Vichy collaborators, something that should be pretty memorable. But Lewis writes that when Kahneman was asked about some event in his past, "he'd say that he didn't trust his memory and so you shouldn't either."
The book opens with a lot on basketball and Daryl Morey. A pretty good read so far (not surprising from Lewis).
