PRE-POSTSCRIPT: Christopher Caldwell has an excellent article in the London Financial Times setting straight the political reality of this crisis: "pragmatism" not only doesn't work, it's precisely what got us into the crisis to start with. "Ideologues" are supposed to be bad, mean people who block "pragmatism"; in fact, they block politically gratifying but false solutions that just cause more problems down the road. It's too bad there weren't more -- many more -- "ideologues" standing in the way of government-sponsored subprime mortgages. There should also have been more "ideologues" (meaning, people who actually know something) more insistent on deflecting the push for a rescue in a more helpful direction.

The incoherent response of the US and other governments is also a case of "pragmatism": myopic reaction, shaped by panic, and not calming down and thinking it through. The economic knowledge to thread governments and markets through this mess is available in abundance. But politicians, journalists, and others in the chattering classes often don't want to hear it.

This misperception is a textbook case of "bubble" psychology. In an undistorted market, lenders, home buyers, and everyone else, would have perceived risk more realistically and acted accordingly. Subprime mortgages would still have happened, but at a lower volume and higher interest rates.

This misperception played a crucial role in the subprime mortgage fiasco....
