Thick Description
Geertz's foundational method: the richly contextual interpretation that distinguishes <em>meaningful action</em> from mere physical movement, revealing what behavior signifies within the webs of meaning that give it weight.
Thick description is Clifford Geertz's term for the interpretive method that situates observable behavior within the cultural context that gives it meaning. A thin description records what happened — a boy contracted his eyelid. A thick description reveals whether the contraction was a conspiratorial wink, a parody of a wink, or an involuntary twitch. The physical behavior is identical across all three; the significance is entirely different, and the significance is accessible only through sustained contextual interpretation. In Geertz's reading of the AI transition, thick description becomes the methodological answer to a civilization drowning in metrics that cannot carry the meaning they purport to measure.

The distinction between thin and thick description was Geertz's 1973 contribution to a long-standing methodological debate about whether the human sciences should aspire to the explanatory rigor of physics or to a different kind of rigor — the kind that attends to meaning rather than measurement. Geertz insisted on the latter. Not because measurement was illegitimate, but
