You can always retroactively find predictions to match reality, but that doesn't mean you have much ability to figure out how much they're guessing more than anyone else at the time. Hindsight is 20/20. I've been reading about how the economy is going to crash next year for 5 years. Of course it seems inevitable that it will crash, but I'm not convinced anyone can predict when. And I'm not sure how many people can predict why.
