There is certainly an epistemological flaw in predictive economics. On the one hand, economic history gives us plenty of data on the behavior of economic systems. Unfortunately, each new economic system is essentially novel. That's why I don't give much credence to economic predictions that are overly precise, and I am skeptical of lessons drawn from long-ago events applied to today's issues. This is where I think Austrian Economics has diagnosed the problem correctly, although its solution (an escape into extreme deductive logic) doesn't appeal to me as a reliable method to discover truths about the world.
