The predictive failures by economists causes a friend of mine to argue that, as a general rule, economists are not scientists at all, and that they are "frauds." In my opinion, he's overstating the point because there were some economists who clearly predicted the burst of the housing bubble, but most of the economists who take to the airwaves don't seem to be scientists like the scientists who develop vaccines or design solar panels. They are often terrible at making predictions, and their lapses can look cataclysmic in retrospect. They are like sportscasters, always looking forward to the next game, trying hard to divert attention from their previous failures. They seem more like lawyers or PR specialists than scientists. This article at Wharton suggests that the economists who failed to predict the housing bubble lack "common sense":
