209. Interesting-- that was actually one of the definining traits of the

authoritarian follower personality type as described by Bob Altemeyer in The Authoritarians.

If someone says a thing they agree with, authoritarian followers tend to assume they're sincere. They have a blind spot for satire and are incredibly vulnerable to charlatans and con-men.

IIRC, the study he cited involved college students reciting opinion-driven essays on topics they were assigned. The people listening to these speakers were informed that the speaker had to argue this position as part of their assignment, and just about everyone understood that. But authoritarian followers almost always said the speaker was sincere and believed the position they were arguing-- so long as the authoritarian themselves also held that position. If they did not, they did not think the speaker was sincere.
