Stephen Joynt - Experts have been wrong before ... a lot. There were these experts once that thought the sun revolved around the earth and anyone who said otherwise was a heretic. They were the scientific experts of their day and they deemed the new theory to be wrong. We all know how that turned out.

Turns out eggs don't cause cholesterol, salt doesn't cause high blood pressure, second-hand smoke doesn't give you cancer, and flossing doesn't improve gum disease.  I know, the experts said ... but now it's been proven .... Or not. 

Experts are only as good as the data they're willing to believe.
