Krugman:

When I read opinion pieces by insiders, I often find the ostensible argument less interesting than what is taken for granted. It’s the throwaway lines, the statements that obviously are meant to refer to what “everyone knows”, that can be truly revealing about the state of conventional wisdom.

Absolutely. It's the assumptions. That's where the trouble lies.

Again K-man, on the presentation of such thoughts:

...so thoroughly accepted that it is mentioned only in passing.

Look for the throwaway lines, and challenge them.
