Ken Burns' ten nearest neighbors are journalists and politicians, with no other directors appearing in the set — a cross-kind pattern that defines the shape of this audience. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.96 indicates very tight overlap.

The top 10 span a narrow band from 0.9486 to 0.9625, consistent with the flat shape classification. Mary Louise Kelly leads at 0.96, followed closely by Pete Buttigieg at 0.96 and Connie Schultz at 0.96. Journalists account for three of the ten slots — Kelly, Schultz, and Steve Inskeep at 0.95 — and politicians fill three more: Pete Buttigieg, Evan McMullin at 0.95, and Jen Psaki at 0.95. The remaining four are more varied: Bradley Whitford (Actors, 0.96), Peter Sagal (TV Personalities, 0.95), Chasten Buttigieg (Professionals, 0.95), and Auschwitz Memorial (Non-Profit, 0.95). The NPR-adjacent cluster — Kelly, Inskeep, and Sagal, all connected to public radio — is notable within the journalist and TV personality slots. The presence of Auschwitz Memorial, the only organizational entity in the top 10, adds a distinct civic-historical thread to an otherwise media-and-politics mix.

The overall picture is an audience shaped by public-affairs media and civic engagement rather than by documentary film or the director subcategory.
