J.K. Rowling's nearest ten audiences span an unusually diverse mix of subcategories — actors, comedians, academics, a professional, an athlete, and an activism account — with no single type dominating the cluster. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.92 indicates near-identical audience shape, regardless of what the entities actually are.
Chris Hadfield sits at the top at 0.92, the only Professional in the set, followed immediately by fellow Author Neil Gaiman at 0.91. Actors Allison Janney (0.91) and Zach Braff (0.90) are nearly as close, and Comedian John Mulaney rounds out the top five at 0.90. Further down, Neil deGrasse Tyson (0.88, Academics), Bill Nye (0.88, TV Personalities), Adam Rippon (0.88, Athletes), Mike Birbiglia (0.88, Comedians), and March For Science (0.88, Activism) complete the ten. Gaiman is the only other Author in the top 10; the remaining nine neighbors come from seven different subcategories. The scores themselves compress into a narrow band — 0.88 to 0.92 — which is the defining structural feature here: no single neighbor pulls decisively ahead of the rest.
This flat, cross-kind distribution suggests an audience whose shape is broadly shared across science communicators, comedians, and actors rather than anchored to any one type.
