MMT economists do not seek to enumerate how many angels can dance on the head of a pin
One of the recurring criticisms that mainstream economists make of Modern Monetary Theory (MMT) is that does not follow the rules of formalism that have become the norm in the economics profession. The implication is that by not following these conventions, MMT economists are unable to say anything precise and scientific. Apparently, a literary discourse cannot convey anything that is sound. Pity that some of the greatest contributions to human knowledge have come from those who could write properly. But this criticism of MMT is about something else again. Dominant academic communities develop their own rules of enquiry, which encompass perspectives of the field to be studied, procedures to be followed, methods and techniques to be used and the end goals of the analysis. If those communities become riddled with Groupthink, then a degree of uniformity in practice becomes expected and enforced either subtly through peer group pressure or more coercively through publication, grant and promotional practices, which effectively determine whether a person will advance or be cast aside. The criticism waged against MMT economists that we don’t follow the normal rules of exposition is really an attempt to enforce the discipline of the mainstream (New Keynesian) community and avoid discussion of substantive issues, such as empirical congruence or extent of anomaly. If the dominant paradigm can convince young scholars and the public that its techniques and methods are the only sound way in which to conduct scientific enquiry and highlight an emerging threat as not being up to speed then it can avoid the scrutiny.
