Two options for economists: Grub around with the data or rely on ...

Hearsay Economics

Paul Krugman, NYT

Jonathan Chait is boggled by Joe Scarborough's latest rant. (Dear Jon: I am not "prickly": I'm aggressive and annoying. But that's by design, and I only do it when the situation calls for it.) What's really striking is Scarborough's certainty that we're experiencing "explosive" spending growth, which is very much not the case:

How do JoScar and others like him come by such misconceptions?

Well, I've gradually come to the realization that most of the commentariat doesn't do what, say Martin Wolf or I do -- grub around in published data, read reports, and all that. Instead, they rely on what they heard somebody say the facts are; hearsay economics. Of course, they don't listen to any old bum on the street; they listen to people of repute, people in their circle. But the repute in question has nothing to do with technical expertise; hey, Admiral Mullen is a serious person, so if he says something on any subject, such as economics, it must be solid.

And where do the reputable people get their information? Why, it's what they heard somebody in their circle say. It's hearsay economics all the way down.
