All ten of Ryan Lizza's nearest neighbors are fellow journalists — Glenn Thrush (0.99), Julia Ioffe (0.99), Alex Burns (0.99), Olivia Nuzzi (0.99), Josh Marshall (0.99), Jeffrey Goldberg (0.99), Josh Dawsey (0.99), Jonathan Martin (0.99), Andrew Kaczynski (0.99), and Jane Mayer (0.99) — and the scores compress into a band of just 0.0051, from 0.9883 to 0.9934.
Similarity here measures how closely two entities' audiences resemble each other in composition. That the top 10 are uniformly journalists, with no crossover into adjacent subcategories — no academics, no politicians, no news publishers — reflects a tightly self-similar audience shape: the people who follow Ryan Lizza look almost indistinguishably like the people who follow other political and investigative journalists. The flat shape means no single neighbor dominates; the field is essentially level across all ten positions. That uniformity, more than any individual pairing, is the structural signal — this audience has a well-defined profile that maps cleanly onto the journalist tier as a whole.
