No, that’s something very different. The point GP is trying to make is that most opinions people hold on things are not actually their own formed conclusions, they are just regurgitations from authorities they trust.

This happens excessively in politics. Suddenly a huge chunk of a political faction will have the same “opinion” on a complex topic they have no day-to-day interaction with or previous educational coverage. When you try to dig deeper on these topics people hold such fervent “opinions” on, it turns out that it’s just a restatement of what they heard from a friend/talking head.
