Beth Harmon's IQ — what the methodology actually says.
"Beth Harmon's IQ" is a popular search. TV Intelligentsia doesn't invent IQ numbers for fictional characters. Here's the honest answer — the show's IQ Score, and what it tells you about how seriously the work treats his mind.
The honest answer
TVI scores shows and films, not characters. Assigning an IQ to a fictional character would be fabrication — we don't have a methodology for that. What we do have: a 0–200 rating of the work's structural intellectual quality, and that score tells you something real about how seriously The Queen's Gambit treats Beth Harmon's mind.
Who Beth Harmon is, and what kind of intelligence the show actually depicts
Beth Harmon (Anya Taylor-Joy) is orphan chess prodigy growing up in Cold War-era Kentucky and rising through Cincinnati, Las Vegas, and Mexico City circuits to face Soviet grandmasters — the rare female protagonist whose specific cognitive fluency is the entire structural plot. The character's intellectual signature in the show is spatial-mathematical chess cognition rendered visually through ceiling-projection sequences, intelligence-rendered-as-actual-craft, the rare YA-streaming protagonist whose intellectual ambition is the show's primary subject rather than its background.
This is the part of the question "what is Beth Harmon'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.
What the IQ Score reveals about the portrayal
The Queen's Gambit scores 158/200 (Stimulating tier — top end) and Beth Harmon is the canonical reason. Taylor-Joy's performance commits to letting chess be the actual subject of the show — not the romance, not the addiction, not the orphanage backstory. The rubric reads what Scott Frank's adaptation argues: that female-protagonist cognition rendered with technical specificity (the chess plays in the show are real and tournament-grade) is rare prestige-TV work. The cultural-impact effect (women's chess participation measurably increased after the show's release) is the rubric reading what audiences absorbed.
