Cited on: /the-hive-mind, HOW A HIVE MOVES AS ONE BODY › More confident, not more accurate. THE PAGE'S OWN GRADE LINE READS: "PROBABLE, one direction tested". Entered 2026-10-12 with the /the-hive-mind rewrite; tag NEW-W1b-9.
3. What it rests on
-
A trusted channel can narrow what its audience knows through the facts it picks, which Broockman and Kalla called "partisan coverage filtering". Regular Fox News viewers paid to watch CNN for a month in 2020 learned what their channel had passed over and moderated some attitudes; their party identity held, and much of the change faded when they went back [SRC-758]. Only that direction has been tested, but a channel serves whoever holds it: German radio slowed the Nazis' rise under Weimar, and once the Nazis held it the effect "was reversed" [SRC-756].
