George Costanza's IQ — what the methodology actually says.

George Costanza (Jason Alexander) is neurotic, perpetually-employed-and-fired short man whose self-defeating tactical intelligence is the show's most reliable comedic engine — pop culture's most enduring portrait of intelligence-applied-against-itself. The character's intellectual signature in the show is tactical anxiety rendered as cognition, social-engineering intelligence applied counterproductively, the rare sitcom protagonist whose smartest moments are also his worst-decision moments.

This is the part of the question "what is George Costanza's IQ" that the search engine flattens. The real question — the one viewers are circling — is whether the show treats his mind seriously. That's the question TVI can actually answer.

Seinfeld scores 109/200 (Competent tier) — and the gap between the show's scoring and its cultural footprint is a useful rubric demonstration. The show is unquestionably foundational comedy; the rubric measures cognitive demand, educational density, and craft, and reads Seinfeld as supremely well-executed without being intellectually demanding. George Costanza is the show's smartest character precisely because his intelligence is always working against his interest — a structural choice played for nine seasons.
