The poll shows expectations for a recession, but the betters at Intrade.com don't see it:

Odds are only 17% for a recession before the end of 2007. People who care enough about the issue to put money down are apparently more optimistic than random phone-answerers.

Have these traders ever correctly anticipated a recession?

Prediction markets are fairly new and weren't in use before the last US recession. They do seem to have had a good record in predicting other things.

On the other hand, the "majority of US population" had never been shown statistically to be better than flipping a coin. The consensus at TOD has been imminent recession ever since I started following the discussion two years ago.
