Economists claim to do science but obviously lack any deeper understanding. Feynman put it thus: “They’re doing everything right. The form is perfect. ... But it doesn’t work. ... So I call these things cargo cult science because they follow all the apparent precepts and forms of scientific investigation, but they’re missing something essential.”#1
What is missing is a proper understanding of what science is all about. The goal of theoretical economics is the true theory: “In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion.” (Stigum)
Economists do not have the true theory. The original methodological blunder of economics is given with the Walrasian microfoundations: “HC1 economic agents have preferences over outcomes; HC2 agents individually optimize subject to constraints; HC3 agent choice is manifest in interrelated markets; HC4 agents have full relevant knowledge; HC5 observable outcomes are coordinated, and must be discussed with reference to equilibrium states.” (Weintraub)
Methodologically, these premises are forever unacceptable. It should be pretty obvious that the Walrasian axiom set contains THREE NONENTITIES: (i) constrained optimization HC2, (ii) rational expectations HC4, (iii) equilibrium HC5. Every model that contains a NONENTITY is a priori false. Its proper place is the wastebasket.
Because it is built on vacuous axioms, economics is a cargo cult science for 150+ years. As far as economists have not realized this, economics is a farce. As far as economists have realized it but are telling the general public that they are doing science economics is a fraud.
Jason Smith’s own blog is simply a bad cargo cultic joke.#2

You say: “[Paul Davidson] Gave a one-hour lunch talk to econ students at the Univ of Chicago and kept muttering under his breath how uneducated they were.”
Heterodox economists are always right telling the students at the Univ of Chicago that they are proto-scientific morons. But the problem of heterodox economists in general and Paul Davidson, in particular, is that Post Keynesianism, too, is axiomatically false.#1
The point to grasp is that economics needs a Paradigm Shift from false Walrasian microfoundations and false Keynesian macrofoundations to true macrofoundations.#2
