2) 根源的なものに完全に従属する、というハード・サイエンスにおけるエートスに則っていない




2) Failure To Follow The Fundamental Full Attribution Ethos of Hard Science

What's wrong with the way Mankiw does economics is that he grabs from other disciplines without attribution. He doesn't label the grabbed items as physics or biology or psychology, or game theory, or whatever they really are, fully attributing the concept to the basic knowledge from which it came. If you don't do that, it's like running a business with a sloppy filing system. It reduces your power to be as good as you can be. Now Mankiw is so smart he does pretty well even when his technique is imperfect. He got the largest advance any textbook writer ever got.

But, nonetheless he'd be better if he had absorbed this hard science ethos that I say has been so helpful to me.

I have names for Mankiw's approach, grabbing whatever you need without attribution. Sometimes I call it “take what you wish,” and sometimes I call it “Kipplingism.” And when I call it Kipplingism, I'm reminding you of Kippling's stanza of poetry, which went something like this: “When Homer smote his blooming lyre, he'd heard men sing by land and sea, and what he thought he might require, he went and took, the same as me.” Well that's the way Mankiw does it. He just grabs. This is much better than not grabbing. But it is much worse than grabbing with full attribution and full discipline, using all knowledge plus extreme reductionism where feasible.
