Pretty much this. You're more or less sampling a pool of people who, actively (and this part is important), actively refuse to think for themselves.

Think about that for a second, they will actually go out of the way to avoid thinking for themselves.

That's why controlling the narrative has been so important for the DS. NPCs need to be told what to think.

That's why we first need to shatter the narrative that holds them, then install the truthful narrative to give these people a new perspective.

Because like it or not they will never change, and need to be spoon fed what is truth and what is not.
