The On Being Project's top 10 nearest neighbors span six different subcategories, with no single type dominating — a composition that reflects a genuinely mixed audience shape rather than a tight niche. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.97 means near-identical audience profiles.
Fresh Air leads at 0.97, the only neighbor to break that threshold, but the gap to the rest of the top 10 is narrow. NPR Books follows at 0.96, and Sarah Kendzior and Jared Yates Sexton — both Authors — sit at 0.96 and 0.96 respectively, making Authors the second most represented subcategory alongside Journalists. Nina Totenberg and Tamara Keith account for both Journalist slots (0.96 and 0.96). Only two of the ten neighbors — Fresh Air and Pod Save America — share On Being's own Podcasts and Radio subcategory, meaning the audience shape is defined less by the podcast format than by a cluster of NPR-adjacent journalists, politically engaged authors, an academic (Kevin M. Kruse, 0.96), a politician (Dan Pfeiffer, 0.96), and — notably — The Onion at 0.96, the lone Websites entry in the set.
The flat shape and cross-kind spread suggest an audience that moves across public-radio programming, political commentary, and literary nonfiction as a single coherent bloc rather than clustering tightly around any one format or figure.
