And: pretty much everyone in the left-right economics debate, from Austrians to neoclassicals to Keynesians to Marxists, thinks of themselves as operating within the mainstream Western intellectual tradition, even if they don’t have the dominant position in economics at the moment. Bias affects all humans, but they all at least like to self-conceptualize as principled followers of evidence.
While they are within the Western philosophical tradition, it’s my impression that neither Austrians nor Marxists can be described as strictly “followers of evidence”, leading me to wonder whether the others can really, either.
The Austrian notion of praxeology, and the Marxist notion of dialectical materialism, are non-empirical. Von Mises insisted on praxeology being an “a-priori science”, like mathematics, rather than an empirical science. Marxist dialectics similarly attempts to begin from axiomatic principles (“laws of dialectics”) rather than measurement.
It’s true that the claims of various schools of thought to be principled followers of the evidence is exceedingly likely to be an exaggeration, if it holds any connection to reality at all. But that doesn’t impugn the claims’ sincerity - or their function as cultural ingroup markers, which is what matters here. (Of course, there are other cultural barriers between them, but none as extreme as that between Creationists ans mainstream biologists, I think.)
“Evidence” can be rationalist as well as empiricist; if the Austrians are right that the laws of economics are discoverable by deduction, then everyone else is wrong to look to the physical world. (Recall the mathemetician’s joke about the physicist who proved all odd numbers are prime: “3 is prime, 5 is prime, 7 is prime, 9 - measurement error, 11 is prime, 13 is prime, viola!”) I think it’s pretty silly for them to think this, of course, but.. For their part I’ve never really seen a western Marxist invoke dialectics except in some very trivial way. What Marxists, Keynesians, and neoclassicals do do (and Austrians also do, although they’d deny they’re doing it) is adopt simplifying assumptions to construct models around. Plausibility limits what one can assume, of course, but choosing the right assumptions is a sufficiently subtle task that each can just as plausibly accuse the others (and, probably more often, their intra-school rivals) of adopting whatever assumptions lead to their preferred conclusions. (My ex ante guess is that the highest proportion of good research takes place within neoclassical and to a lesser extent Keynesian, but only because its status gives it better access to talent and funding, and scrubs away any ideology-signaling effects of working within the discipline.)
