Relentless Decency

Paul Krugman:

Macroeconomic Morality 

A brief postscript to today’s column: contrary to what some people may think, I don’t regard anyone who disagrees with me as necessarily a mendacious idiot. Economics is hard, and people will disagree. Sometimes people will give advice with the best of intentions that turns out, in hindsight, to have been disastrous; that’s a tragedy but not a sin.

But here’s what is indeed a sin: choosing your position based on what is personally convenient.

I may make jokes along the way – I kind of need to in order to stay sane – but the stuff I write about is extremely serious; there’s a vast human tragedy taking place, and anyone who has the ear of the public has a duty to make a good-faith effort to get it as right as he can.

Yet all too many players in this game, very much including economists and public officials, very obviously haven’t been making that good faith effort. They’ve seized on dubious arguments, touted obviously weak evidence as definitive, looked for excuses either not to act themselves or for their friends not to act. And invariably the thrust of these bad arguments is to comfort the comfortable and give them license to afflict the afflicted.

I like to think that I have enough integrity to change my views when it becomes clear that they were wrong. Maybe, maybe not — although it’s probably worth pointing out that I didn’t believe in the liquidity trap and was pretty down on old-fashioned Keynesianism until 1998, when a hard look at Japan and an attempt to understand what was happening there led me to change my mind. Anyway, I try, because the ideas of economists and political philosophers matter.

And too many people aren’t trying, which is, as I said, a sin.

Dr Krugman has been hammering this point home of late. Economics really shouldn't be like this; it's almost a science, after all. But if, as Dr Krugman laments, so many are so determined to blind themselves to the facts, either out of corporate fealty or out of simple ignorance, valuable resources are diverted to debunking curious claims. It's bad enough that charlatans and shills scream for our attention; the true shame is that our best minds must occupy themselves with such nonsense.

Yann Giraud:

Yet, the same Paul Samuelson had written to his friend Alvin Hansen a couple of years before, in the midst of the Phillips curve controversy, the following sentence: "Milton F. is a bloody nuisance. In the end he is not right in his provocative stands, but it takes valuable time rebutting his arguments." He even added: "Having just returned from UCLA where (as in Virginia and Washington) the place is jumping with energetic libertarian nuts, I realize that so much of one's scientific life has to be occupied in sterile debate." [emphasis added]
