Scientific American's top 10 neighbors span five distinct subcategories — magazines, activists, news publishers, authors, and a website — with no single type dominating and scores compressed into a narrow band from 0.97 to 0.96.
The shape is flat: Science Magazine leads at 0.97, but Greta Thunberg (0.97, Activists) and Nature News & Comment (0.97, News Publishers) are effectively tied with it. Ed Yong (0.96, Authors) and Justin Trudeau (0.96, Politicians) follow just behind. The three fellow magazines in the top 10 — Science Magazine, New Scientist, and The Lancet — are the only same-kind neighbors; the remaining seven positions belong to activists, politicians, authors, a news publisher, and a website (Ars Technica, 0.96). That cross-kind spread is the defining structural feature: the audience shape Scientific American shares most closely is not confined to science publishing but extends into politically engaged and civically oriented figures and outlets. The presence of two politicians — Trudeau and Andrew Yang (0.96) — alongside activists like Thunberg and Malala Yousafzai (0.95) suggests the audience composition overlaps substantially with entities associated with public-interest discourse rather than science media alone.
The flat shape, with a spread of only about 0.02 across all ten neighbors, indicates an audience that is broadly shared across a wide range of civic, scientific, and journalistic entities rather than tightly concentrated around any single one.
