Hidden Brain's top 10 neighbors span journalists, fellow podcasts, a TV personality, an academic, and an author — no single subcategory dominates, and the scores compress into a narrow band from 0.97 down to 0.96, the defining signature of a flat shape.
The two highest-scoring neighbors tie at 0.97: Nina Totenberg and Kai Ryssdal, both Journalists. Marketplace (0.97), a fellow Podcast and Radio channel, sits just behind them, followed by journalist Steve Inskeep at 0.97 and TV Personality Peter Sagal at 0.96. Rounding out the top 10 are Wait Wait Don't Tell Me (0.96, Podcasts and Radio), Morning Edition (0.96, Podcasts and Radio), academic Kevin M. Kruse (0.96), journalist Mary Louise Kelly (0.96), and James Martin, SJ (0.96, Spiritual Leaders). Tallying the subcategories: four Journalists, three Podcasts and Radio, one TV Personality, one Academic, and one Spiritual Leader. Journalists are the plurality, but no single kind commands the cluster. Notably, the NPR ecosystem — individual hosts, programs, and adjacent public-radio properties — accounts for most of the set, even when the subcategory labels differ.
The flat shape and tight score range together indicate an audience that is broadly distributed across a coherent public-media world rather than anchored to any single neighbor or type.
