Because "now has his doubts" adds a temporal change that's incorrect. There is nothing in the article that says he's "now" had a suddent shift. He has formed no new "doubts". Fama has always made the distinction that it's a hypothesis, not reality. e.g. 'I start my class every year by saying, “These are models.
