How Economics Became A Religion

Is economics really a science? Not according to author John Rapley. In this Guardian long read, Rapley makes the case that the discipline is much closer to a religion - complete with a doctrine, ideology, moral code "promising adherents salvation in this world", and even a sort of priesthood with prophets and reformists "who uphold orthodoxy in the face of heresy".

His argument has a certain coherence: he writes how, in an effort to establish economics as a science, it's practitioners: 

"had to dispense with scientific method at times. For starters, it rests on a set of premises about the world not as it is, but as economists would like it to be. Just as any religious service includes a profession of faith, membership in the priesthood of economics entails certain core convictions about human nature ... that we humans are self-interested, rational, essentially individualistic, and prefer more money to less. These articles of faith are taken as self-evident".

Yet, when economic data is tested by scientific method, Rapley points out the results are often inconclusive. Take, for example, the two economists who split the Nobel prize in economics in 2013 - one, named Eugene Fama, who asserted that prices created in a market are always correct, and Robert Shiller, who insisted that markets frequently got the price wrong, "a bit of Solomon wisdom that would have elicited howls of laughter had it been a science prize".

Part of the problem, of course, is that unlike hard science, economics relies on human data, and humans do not always act reliably and are prone to changing their minds. Or, as Rapley puts it, "Just as you can find a quotation in the Bible that will justify almost any behavior, you can find human data to support almost any statement you want to make about the way the world works." 

So what now? Rapley ends his piece with a call to action: economists must admit the limitations of their discipline. Only then, he writes, can economics serve us once more.
