If the people on the jury started to see themselves as a coherent group, then they can change minds and reach consensus. People listen to other people in their in group way more.
If you try to talk to a maga person, and they see you as a Outsider, you’re going to have a very difficult time getting them to listen to anything you say.
We all do this to some extent.
It’s just really bad currently that the maga people will look to their group for consensus reality, and they have mostly bad ideas.
