Economists aren't supposed to have personalities - not the good ones anyway.
Paul Krugman is one of those genius-level guys who can take something as ridiculously complicated as economics and explain it in a way that makes it more or less understandable for a dope like me.
One criticism I face fairly often is the assertion that I must be dishonest — I must be cherry-picking my evidence, or something — because the way I describe it, I’m always right while the people who disagree with me are always wrong. And not just wrong, they’re often knaves or fools. How likely is that?
But may I suggest, respectfully, that there’s another possibility? Maybe I actually am right, and maybe the other side actually does contain a remarkable number of knaves and fools.
The first point to notice is that I do, in fact, perform a kind of cherry-picking — not of facts, but of issues to write about. There are many issues on which I see legitimate debate, from the long-run trend of housing prices to the effects of immigration on wages. And in happier times I would probably write more about such issues than I do, and the tone of my column and blog would be a lot more genteel. But right now I believe that we’re failing miserably in responding to economic disaster, so I focus my writing on attacking the doctrines and, to some extent, the people responsible for this wrong-headed response.
But can the debate really be as one-sided as I portray it? Well, look at the results: again and again, people on the opposite side prove to have used bad logic, bad data, the wrong historical analogies, or all of the above. I’m
Krugtron the Invincible!
Am I (and others on my side of the issue) that much smarter than everyone else? No. The key to understanding this is that the anti-Keynesian position is, in essence, political. It’s driven by hostility to active government policy and, in many cases, hostility to any intellectual approach that might make room for government policy. Too many influential people just don’t want to believe that we’re facing the kind of economic crisis we are actually facing.
And so you have the spectacle of famous economists retreading 80-year-old fallacies, or misunderstanding basic concepts like Ricardian equivalence; of powerful officials instantly canonizing research papers that turn out to be garbage in, garbage out; and so on down the line.
I know, the critics will respond that I’m the one who’s being political — but again, look at how the debate has run so far.
The point is not that I have an uncanny ability to be right; it’s that the other guys have an intense desire to be wrong. And they’ve achieved their goal.
