I think they're referring to the NPC programming that people receive through media/authority figures, and only have those views because "my fellow tribe member on Fox News/CNN said so"

You can't really blame them though, the average person simply doesn't have the time to be well researched on a given topic, and so are going to default to tribal thinking that when you poke at, falls apart.

It has nothing to do with inability to articulate their position, and everything to do with the fact that there simply isn't enough time for most people to become well informed on a given topic.
