John Locke's IQ — what the methodology actually says.
"John Locke'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 Lost treats John Locke's mind.
Who John Locke is, and what kind of intelligence the show actually depicts
John Locke (Terry O'Quinn) is wheelchair-bound paper-company employee whose post-plane-crash recovery of his ability to walk transforms him into the show's spiritual-philosophical anchor against Jack Shephard's scientific-empirical register. The character's intellectual signature in the show is philosophical-faith cognition operating in opposition to scientific-empirical cognition, intelligence-as-belief-applied-against-evidence, the rare prestige-TV character whose name (literally John Locke, the philosopher) signals the show's structural argument about empiricism vs faith.
This is the part of the question "what is John Locke'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
Lost scores 151/200 (Stimulating tier) and John Locke is the structural reason the show operates as actual philosophical inquiry rather than mystery-genre puzzle. Terry O'Quinn's performance committed to letting Locke's specific faith-cognition be presented as coherent rather than as easy comic-relief or villain framing. The rubric reads what J.J. Abrams and Damon Lindelof built: that the man-of-faith / man-of-science conflict (named after the actual Enlightenment-philosophy figures) is the show's actual subject, and Locke's character is the half of that conflict whose worldview the show treats as genuinely available.
