Why IR scholars should care about quantum theory, part II: critics in the PITs

Abstract Part II responds to some of my critics' substantive concerns about QMASS. However, to sharpen that discussion I first introduce the idea of classical and quantum physical instantiation tests or ‘PITs’. PITs are a thought experiment taking advantage of the causal closure of physics. To encourage critical self-reflection on the usually tacit ontological assumptions of our theories, PITs invite social scientists to translate their mostly qualitative, folk psychological arguments into physical descriptions, meeting classical and quantum constraints respectively, to see which feels more appropriate to the case at hand. With this diagnostic tool in hand, the paper addresses criticisms of QMASS in five areas: (1) the threat of physics reductionism; (2) the potential for epistemic repression stemming from the realist nature of QMASS’ argument; (3) doubts that a quantum approach can support a genuine notion of human freedom; (4) the place of ethics and normativity in social and international life; and (5) implications for graduate methods training and quantum pedagogy more generally.
