I meant the books, which are not very detailed and focus on his genius at predicting whole societies, but not separate people, yadda-yadda, the author might have liked that specific detail, except it's wrong, a society consists of all its members, and predicting one person is still easier. I suspect that's because Foundation is actually a utopia, something showing how science and genius are always ultimately on the side of the good. IRL that's not true.
