Hermione Granger's IQ — what the methodology actually says.

Hermione Granger (Emma Watson) is the bookish, brilliant member of the Harry Potter trio whose competence is the structural reason the central plot resolves — pop culture's most-cited example of the studious-girl-as-actually-the-smart-one character. The character's intellectual signature in the show is academic-research intelligence rendered as the central engine of friend-group problem-solving, intelligence-as-care, the rare YA-franchise character whose smartness is shown to be the source of moral courage.

This is the part of the question "what is Hermione Granger'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.

The Harry Potter franchise scores in the Stimulating-to-Masterclass band depending on the installment, and Hermione is the consistent through-line. The rubric reads what audiences have absorbed: the studious-girl trope rendered with enough specificity (she does the reading, she works the problem, she shows the working) that millions of children watched a YA series and noticed that intelligence applied to real problems is what saves the protagonists. That's the structural achievement.
