Instrumentalism is a philosophical perspective within the philosophy of science that emphasizes the instrumental or pragmatic value of theories and models rather than their absolute truth or correspondence to reality. Proposed by philosophers such as William James and later developed by thinkers like Pierre Duhem and Ernst Mach, instrumentalism argues that scientific theories are not descriptions of how the world *is* but rather useful tools for predicting and explaining phenomena. The focus is on the practical utility of these tools in solving problems and making accurate predictions, rather than their literal accuracy in representing reality.

At its core, instrumentalism suggests that the truth of a scientific theory is secondary to its effectiveness in generating correct outcomes. For example, Newtonian mechanics was highly successful in predicting planetary motion, even though it was later superseded by Einstein’s theory of relativity. Instrumentalists would argue that Newton’s laws were not "false" but merely less useful in certain contexts. This view contrasts with realism, which posits that scientific theories aim to describe an objective reality independent of human observation.

Instrumentalism has influenced various fields, including physics, psychology, and the philosophy of science. In science, it supports the idea that theories are provisional and subject to revision as new evidence emerges. Critics, however, argue that instrumentalism can lead to skepticism about the existence of objective truths, as theories may be treated as mere conventions rather than approximations of reality. Despite these concerns, instrumentalism remains a significant framework for understanding the nature of scientific knowledge and its relationship to the world.
