Fuzzy Demarcation Theory of Science

A model of demarcation—distinguishing science from non‑science—that rejects binary boundaries (science/pseudoscience) in favor of graded membership. Instead of sharp dividing lines, fuzzy demarcation treats “scientificness” as a matter of degree, based on multiple criteria (testability, empirical support, coherence, etc.). A field can be more or less scientific depending on context, and boundaries are gradual. This avoids the problem of essentialism, where a single feature (like falsifiability) excludes legitimate but messy disciplines such as historical geology or early epidemiology. Fuzzy demarcation acknowledges that science is a cluster concept, not a checklist.

Example: “The fuzzy demarcation theory of science allowed her to place astrology low on the spectrum—not absolutely ‘non‑science,’ but very far from physics, while recognizing that some ‘fringe’ areas might inch closer with better methodology.”
