Logan Roy's IQ, and what Succession's IQ Score actually reveals.
How smart is Logan Roy? Smart enough that "Logan Roy's IQ" is one of the most searched questions about Succession. Here is the defensible read of the mind the show actually builds, the 160/200 IQ Score behind it, and why no invented number does it justice.
The answer
Logan Roy anchors Succession as one of its central intelligences, and the show earns a 160/200 IQ Score (Masterclass tier) for how seriously it builds that mind. That score is the real, measurable answer the search is circling. The specific IQ figures floating around online are invented; no clinical IQ test applies to a fictional character, and TVI does not fabricate one. We rate the work, not the character, on a published 0 to 200 rubric.
Who Logan Roy is, and what kind of intelligence the show actually depicts
Logan Roy (Brian Cox) is media-conglomerate patriarch whose intelligence is almost entirely instrumental, strategic, predatory, and applied across decades. The character's intellectual signature in the show is long-horizon strategic thinking, predatory empathy (reading people to control them), refusal to perform intelligence as a moral category.
This is the part of the question "what is Logan Roy's IQ" that the search engine flattens. The real question, the one viewers are circling, is whether the show treats Logan Roy's mind seriously. That's the question TVI can actually answer.
What the IQ Score reveals about the portrayal
Succession scores 160/200 (Masterclass) because Jesse Armstrong's series treats institutional intelligence as the actual subject. Logan Roy is one of television's most precise studies of how strategic intelligence operates at scale, not in any single scene but in the gravitational pull he exerts across four seasons. The rubric rewards exactly this kind of structural commitment.
