In an op-ed in the Wall Street Journal Joseph Epstein repeats a theme I have enunciated myself:
Whether economics is a science at all has long been in doubt, chiefly because the subject is heavily politicized. There are no liberal and conservative physics, no right- or left-wing chemistry, but economists do line up politically—Marxists vs. free-marketeers, Keynesians vs. Hayekians—in a way that squashes the claim to objective scientific standing.
“I much like Milton Friedman, George Stigler, Gary Becker and other of the University of Chicago economists,†my friend Edward Shils once told me. “But you know, Joseph, I fear they are insufficiently impressed by the mysteries of life.†Years ago I was at lunch with a Chicago-trained economist who asked me about an article on the subject of psychiatry going awry that was about to run in a magazine I was editing. I mentioned that one of the ways it had done so was by blithely accepting transgender surgical operations, which the author of the article argued would one day be viewed as the lobotomies of our time.
“I happen to know that until now there have been no lawsuits against physicians performing these surgeries,†my companion replied, “so I assume market satisfaction.†I gulped. Market satisfaction—surely the least interesting aspect of the complex subject of transgender surgery, and further evidence of the shortsightedness of economic thinking.
In a sense his op-ed is self-refuting. Psychology is politicized, too. All of the social sciences are politicized, especially when money is involved. As to there being no Democratic or Republican physics, give it time. That’s being worked on.
My view is that it is quite possible to be a science but not a predictive science and that economics fits that description quite neatly. It’s a descriptive science like anthropology or sociology not a predictive one like chemistry or physics.
A distinctive problem that economics has that anthropology does not is that an alarming number of economists were inspired to pursue the study by reading Isaac Asimov’s Foundation series. There are far too many would-be Hari Seldons out there, longing to direct the course of human history over a period of thousands of years. It might be that economics will arrive at that point some day but that day is millennia away.
Meanwhile, while it’s very helpful as a guide to policy to know that the higher the price, the fewer the purchases (for ordinary goods) don’t expect an economist to tell you how many sales will be lost by increasing the price of something by a dollar.
