What is continuous vs discrete categories?

Continuous vs discrete categories is a concept in personal epistemology: Many things are better understood as positions on a continuum than as discrete categories.

Example: A doctor asks 'rate your pain from 1 to 10.' That question captures more information than 'are you in pain?' because the same binary answer — yes — covers a papercut and a kidney stone. The 1-to-10 scale preserves the gradient, and the gradient is what determines the treatment. Your classification systems work the same way: every time you collapse a spectrum into a binary, you lose the information that matters most for action.

This concept is part of Phase 12 (Classification and Typing) in the How to Think curriculum, which builds the epistemic infrastructure for classification and typing.
