Economics is a post hoc explanation for how the market works. It's not like somebody came up with the theory of how a market should work and then built one, like you would a computer. Rather, markets existed back in the middle ages before economists did, increased the wealth of its participants, and economists later appeared to explain why that was the case. Nowhere is the prerequisite that this system is the result of logical design.

- bobosha 6y agoEconomics, especially Behavioral economics, is Descriptive, not prescriptive.
- tomjakubowski 6y agoClassically (read: what I was taught in AP Econ 15 years ago), "normative economics", which is prescriptive and meant to inform policy, is divided from from "positive economics", which attempts to describe and rationalize economic activity. https://en.wikipedia.org/wiki/Normative_economics https://en.wikipedia.org/wiki/Normative_economics

It's not like somebody came up with the theory of how <Subject Y> should work and then built one, like you would a computer. General relativity is a post hoc explanation for how large-scale spacetime works. It's not like somebody came up with the theory of how the universe should work and then built one, like you would a computer. Darwinian evolution is a post hoc explanation for how life forms change over time. It's not like somebody came up with the theory of how life on earth should work and then built one, like you would a computer.
- randallsquared 6y agoThose are good analogies (if more precise and more easily testable than is typical in the social sciences), but the framing suggests you don't believe they are.
- ORioN63 6y agoI read as OP believes examples are common enough, that saying it, is the same as not saying anything at all.
- awild 6y agoThe difference being that we've already gotten past the point of thinking that Darwinian theory should dictate human lifes. A lot of political energy is invested in keepingn them the way particular theories say it ought to be based on certain economic theoretical criteria. You wouldn't kill the baby of a Tiger/Lion simply because your textbooks say it's not genetically feasible (glossing over the fact that it's simply not been observed before).
- netcan 6y agoThere were economists in the middle ages. Ibn Khaldun, Maimonides.... Even before then. I believe Rome hanged (or crucified maybe) a whole generation of them during the crisis of the third century.
