Skulls full of mush. I’m speaking of course of the faculty.
Group think is the result of putting useful idiots in the same room. As long as there is a charismatic speaker who can influence young mush heads, there will always be group think.
The reason Conservatives are not co-opted by group think is because we don’t look to people as leaders, only peers with a common belief. The TEA Party is a perfect example. It wasn’t a group of people, but thousands of individuals.
