1. instrumentalism
Wikipedia definition
2. InstrumentalismIn the philosophy of science, instrumentalism is the view that a scientific theory is a useful instrument in understanding the world. A concept or theory should be evaluated by how effectively it explains and predicts phenomena, as opposed to how accurately it describes objective reality. Instrumentalism avoids the debate between anti-realism and philosophical or scientific realism. It may be better characterised as non-realism.
