Studying common sense comparatively requires understanding how it becomes uncommon and changing.

Evidence

Anthropology has no privileged claim on the study of common sense nor the epistemologies that underwrite it. But as Michael Herzfeld argues, anthropology may have special purchase on how to go about its comparative study. I am less sure we can really make that claim. For such expertise in common sense we would need to become far more proficient at studying the changing parameters of common sense, how common sense is rendered uncommon, and how people know it. — Ann Laura Stoler, Along the Archival Grain_ Epistemic…, 240
