But there’s something else in David’s column, which I see a lot: the argument that because a lot of important people believe something, it must make sense:
Moreover, the Demand Siders write as if everybody who disagrees with them is immoral or a moron. But, in fact, many prize-festooned economists do not support another stimulus. Most European leaders and central bankers think it’s time to begin reducing debt, not increasing it — as do many economists at the international economic institutions. Are you sure your theorists are right and theirs are wrong?
Yes, I am. It’s called looking at the evidence.
Because, you see, no one else on the other side has ever even bothered to look at the evidence!
You could fill a small sand bucket with what I know about economics, so I'm not interested in the rightness or wrongness of Krugman's position vis-a-vis demand side economics in the present recessionary environment. What is truly amazing is that he argues not that he's probably right. Or that the evidence supports his case more so than the opposite. He has absolute, God-given certainty as to his total and complete correctness and equal certainty that anyone who differs is a fool or a liar.
Even he was talking about, I don't know, outlawing abortion or invading Iraq, you might think he was a blinkered ideologue.
