Wiktionary gives two definitions: 1. The belief that the scientific method and the assumptions and research methods of the physical sciences are applicable to all other disciplines (such as the humanities and social sciences), or that those other disciplines are not as valuable. 2. The belief that all truth is exclusively discovered through science. The two definitions above are closely linked. They are both about a value judgment that only scientific truths are meaningful or valid or relevant. The definition you give is distinct from those, but it seems like the kind of term people would invent. I imagine that lexicographers are keeping an eye on how wide that usage becomes.
