Maybe we should add this to the growing list of blog posts on http://angry-economist.russnelson.com/ http://angry-economist.russnelson.com/ that show where Paul Krugman has been dead wrong in his area of expertise.

It's difficult to be correct if your area of expertise is predicting the future.

  "It's difficult to be correct if your area of expertise is predicting the future." A very good point. I like the definition of "expertise" championed by K. Anders Ericsson, a researcher on expertise and how it develops. He defines expertise as RELIABLY superior performance to a degree that makes the performer a statistical outlier. In one of his studies, he discovered that there is no such thing as expertise in choosing common stocks in which to invest.

  I don't know that his job is to predict the future. He's an economist, not a fortune teller. Of course, science can help us to "predict the future", in the sense that we know the sun will rise tomorrow and so on. But economics is not a natural or experimental science. Surely it can help you make reasonable predictions, but the nature of methodologically correct economic predictions -- meaning not necessarily predictions that turn out to be right, but ones you can reasonably make -- is much different from those of physics. Therefore, Krugman and other economics and financial pundits should rather refrain from making unsupported predictions. I think they get away with it because most people don't understand economics and also due to selection bias, as most of us pay attention only to the ones that turn out to be right.

  Also: Russ Nelson is a smart, nice guy, and a good programmer, but to my knowledge, he is not an "economist" in the sense of someone with a degree, or employed in some capacity in that field. His bio doesn't mention economics at all: http://russnelson.com/bio.html http://russnelson.com/bio.html That's not to say that what he has to say is wrong, but it's a bit odd to attach the 'economist' label when I'm not sure he has really earned it any more than many of us with an interest in the field and a bit of reading under our belts.
