Raquel Fernandez the Cynic

Here's an interview with Raquel Fernandez. This concludes with:

Economists essentially have a sophisticated lack of understanding of economics, especially macroeconomics. I know it sounds ridiculous. But the reason why I tell people they should study economics is not so they’ll know something at the end—because I don’t think we know much—but because we’re good at thinking. Economics teaches you to think things through. What you see a lot of times in economics is disdain for other's lack of thinking. You have to think about the ramifications of policies in the short run, the medium run, and the long run. Economists think they’re good at doing that, but they’re good at doing that in the sense that they can write down a model that will help them think about it—not in terms of empirically knowing what the answers are. And we have gotten so enamored of thinking things through that the fact that we don’t know anything needs to bother us more. So, yes, it’s true that the average guy on the street doesn’t understand economics, and it’s also true that we don’t understand economics. We just have a more sophisticated lack of understanding than the guy on the street

Fernandez knows something, about which she is quite certain. As economists, we really don't know anything at all. Apparently we are good at thinking, but it's just fooling around - nothing more serious than video games.

Fernandez is frustrated:

The methodology of economics is so strong that we have had a large impact on many fields, from political science to sociology and even neuroscience. It’s been a very successful paradigm in that what economics does very well is think rigorously. But sometimes that’s not been very fruitful in the sense that there are certain questions that you can’t ask because you don’t know how to model them.

Ah, those pesky models, getting in the way of fruitful science.

Fernandez thinks we're not scientists:

... as “scientists” we often don’t have much to say. I don’t think we are scientists. I think we’re more like doctors in the sense that we do research, but in the end there’s a patient, and you have to say, given one’s knowledge, what’s the best way to treat the patient?

Well, when I think about my doctor, what she does looks to me like applied science. She wants to do some tests on me. I ask her some questions about it. She cites scientific evidence from published research. When I talk to Jim Bullard I get the same vibes. He's doing applied science. He knows what's in the journals. He talks to his staff and other economists, and uses frontier knowledge to argue for good policy choices. That frontier knowledge is based on theory, i.e. models, and empirical evidence. Science, basically.

Fernandez thinks we don't love Paul Krugman enough:

But the people who go and give advice usually end up with a very bad rap in economics. I am amazed at how much hatred—and I will say hatred—Paul Krugman evokes from some fellow economists. But one of the reasons for this is that he says things for which there is not “scientific” support and which go against what these people believe is "good" economics.

She's confused here. Krugman does not get a bad rap because he chooses to give advice. He gets a bad rap because some people, me included, think he is giving bad advice. We don't hate the man, we just disagree with him. And yes, this has a lot to do with science (no scare quotes).
