Joseph Cooper's IQ — what the methodology actually says.
"Joseph Cooper'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 Interstellar treats Joseph Cooper's mind.
Who Joseph Cooper is, and what kind of intelligence the show actually depicts
Joseph Cooper (Matthew McConaughey) is former NASA test pilot turned dustbowl-Earth farmer recruited to pilot the Endurance through a Saturn wormhole on a colonization-search mission — Christopher Nolan's most-emotionally-direct protagonist. The character's intellectual signature in the show is test-pilot-engineering intelligence applied to general-relativistic time dilation, intelligence-as-fatherhood-rendered-across-temporal-distance, the rare science-fiction protagonist whose technical fluency and emotional commitment coexist as the structural plot.
This is the part of the question "what is Joseph Cooper'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
Interstellar scores 189/200 (Masterclass tier — among the highest in the database) and Joseph Cooper is the structural reason. McConaughey's performance committed to letting the protagonist's fatherhood (the Murph video-message sequence, the bookshelf-tesseract communication) be the emotional engine the rest of the science-fiction architecture supports. The rubric reads what Christopher and Jonathan Nolan built: that relativistic-time and black-hole physics can be the structural subject of an emotionally-direct father-daughter film rather than mere genre setting.
