Mr. Paul cannot say it better about wisdom or insight

I said similar thing when I discussed why you may be interested in my blog. 

"This is what you need to know: important people have no special monopoly on wisdom; and in times like these, when the usual rules of economics don’t apply, they’re often deeply foolish, because the power of conventional wisdom prevents them from talking sense about a deeply unconventional situation."
