Peter Sagal's top 10 neighbors are dominated by journalists and public-radio programs — not other TV personalities, and not comedians. Five of the ten are journalists: Steve Inskeep (0.98), Kai Ryssdal (0.98), Mary Louise Kelly (0.98), Nina Totenberg (0.98), and Ari Shapiro (0.98). Two more are public-radio programs — Wait Wait Don't Tell Me (0.98) and All Things Considered (0.98). The remaining three are Ken White (0.98, Professionals), Jennifer Gunter (0.98, Activists), and FiveThirtyEight (0.97, Websites).

The shape is flat: all ten scores fall within a narrow band of 0.97 to 0.98, with no single neighbor pulling away from the rest. No other TV personality appears in the top 10 — the audience composition here is defined almost entirely by public-radio journalism and its adjacent orbit. The cross-kind character is the structural finding: Sagal's audience looks far more like the audience for NPR correspondents and flagship programs than for anyone in his own subcategory.

This pattern suggests an audience organized around a specific media ecosystem — public-radio and civic-minded commentary — rather than around the format or genre of the center entity itself.
