'''Scientific instrumentalism''' is the view that scientific theories are not descriptions of an underlying reality but instruments for predicting observable phenomena and organizing experience. On this account, electrons, genes, and gravitational fields are not "real" entities to which theories correspond; they are convenient fictions that generate correct predictions. The instrumentalist does not ask whether a theory is true but whether it works — where "works" means successfully anticipates observations and guides practical intervention.

The position has ancient roots in the pragmatism of [[William James]] and [[John Dewey]], but it achieved its sharpest formulation in debates over [[Quantum Mechanics|quantum mechanics]], where the [[Copenhagen Interpretation|Copenhagen interpretation]]'s dismissal of questions about the underlying state of nature resonated with instrumentalist intuitions. It also aligns with [[Rudolf Carnap]]'s [[Principle of Tolerance]], which treats ontological commitment as a pragmatic choice rather than a factual discovery. The central challenge to instrumentalism is the "success argument": if theories are merely instruments, why do they consistently produce novel predictions about phenomena never previously observed? The instrumentalist reply — that successful prediction is precisely what makes an instrument valuable — strikes realists as question-begging. The debate remains unresolved because both sides are partially right: theories function as instruments, but their instrumental success is difficult to explain without positing some structural correspondence between theoretical claims and the systems they model.
