The underlying binary code of criminal proceedings is guilty/not-guilty. The accused has an interest at a clear-cut not-guilty outcome if he is indeed not the wrongdoer. On the other hand, the accused, if he is indeed the wrongdoer, has an interest to arrive somewhere in the middle between guilty/not-guilty. Therefore, what he applies is a stratagem, that is, he blurs and obstructs the underlying binary distinction in all possible ways.
The situation is analogous in science where the underlying binary code is true/false. The genuine scientist tries to sharpen the issue in hand in order to eventually arrive at a clear-cut true/false answer. Everything in-between is scientifically worthless. The cargo cult scientist (Feynman’s term), on the other hand, tries everything to keep the issue safely in the no-man’s land between true/false, where “nothing is clear and everything is possible.” (Keynes)
The term ‘conventionalist stratagem’ has been introduced into methodology by Popper (see here). Boiled down to essentials it amounts to the application of all possible communicative means in order to prevent a clear-cut true/false outcome.
“Plato’s main concern with the Sophists is that their rhetoric does not provide an adequate view of justice
- Doxa – public opinion: Sophistic manipulation of doxa is aimed at persuasion only,
- Episteme – true knowledge: Plato’s goal beyond persuasion is to discover epistemic truth.” (see here)
By proudly advertising that they have a model for every season, Wren-Lewis and Rodrik fall back methodologically to the proto-scientific position of the Sophists.
There is no better empirical proof of scientific incompetence than to apply proto-scientific stratagems. To be sure, this holds for both orthodox and heterodox economists in equal measure. Wren-Lewis and Rodrik are not the exception but the rule. And this is why economics is a failed science.
