But if I hadn't read Friedman's writing from 2002-2006, then I wouldn't know how terribly wrong he has been, and I would be too credulous about his claims.

I think this is a false premise: if you'd been reading Friedman's writing over that period with any attention to his subject matter and the claims he makes about it, then you would know how terribly wrong he has been. That's the only way anyone could know that. If you are reading him, and plan to read EY's writing, with no attention to their subject matter and the claims they make, then of what use would a reliability check be?

Just read his posts, look some of the stuff up on your own, and decide for yourself if they make sense. That's the best anyone can do. It would be a waste of EY's time, and/or yours, to go through a list of predictions.
