Apropo topic of Freakonomics: Predicting the future

Interesting entry today; not saying it's directly related to any fellow bloggers, but an excerpt from Levitt's opinion:

"...the person who makes that prediction has a strong incentive to remind everyone that they made that crazy prediction which came true.
...if you’re wrong, there’s no person on the other side of the transaction who draws any real benefit from embarrassing you by bring up the bad prediction over and over."
