Except for your extrapolation, that's an excellent example, and it needs to be brandied about a hell of a lot more than it is because doing so builds credibility!

My high school science teacher telling me that we were running out of oil and that gas would be $10 a gallon by the time I entered the workforce did not build credibility.

This is an iterated game. The takeaway is that it's important to be right, important to not be wrong, and important to make sure people know it, not that it's important to lie your ass off (sorry, overstate your cause) in a misguided attempt to help.
