One of his research findings was that authoritarians are more likely than others to have poorly integrated beliefs: they can hold mutually contradictory beliefs and flip between them at will:
As I said earlier, authoritarians' ideas are poorly integrated with one another.
It's as if each idea is stored in a file that can be called up and used when the
authoritarian wishes, even though another of his ideas--stored in a different file--
basically contradicts it. We all have some inconsistencies in our thinking, but
authoritarians can stupify you with the inconsistency of their ideas. Thus they may say
they are proud to live in a country that guarantees freedom of speech, but another file
holds, "My country, love it or leave it." The ideas were copied from trusted sources,
often as sayings, but the authoritarian has never "merged files" to see how well they
all fit together.
It's easy to find authoritarians endorsing inconsistent ideas. Just present slogans
and appeals to homey values, and then present slogans and bromides that invoke
opposite values. The yea-saying authoritarian follower is likely to agree with all of
them. Thus I asked both students and their parents to respond to, "When it comes to
love, men and women with opposite points of view are attracted to each other." Soon
afterwards, in the same booklet, I pitched "Birds of a feather flock together when it
comes to love." High RWAs typically agreed with both statements, even though they
responded to the two items within a minute of each other.
But that's the point: they don't seem to scan for self-consistency as much as
most people do. Similarly they tended to agree with "A government should allow total
freedom of expression, even it if threatens law and order" and "A government should
only allow freedom of expression so long as it does not threaten law and order." And
"Parents should first of all be gentle and tender with their children," and "Parents
should first of all be firm and uncompromising with their children; spare the rod and
spoil the child."
(RWA = right-wing authoritarians)
He also refers to research by Mary Wegmann showing that RWAs "had more trouble remembering details of the material they'd encountered", and "the authoritarians had lots of trouble simply thinking straight". To a normal person watching that show, the contradiction would be glaringly obvious, but the target audience are used to holding contradictory ideas, have a short attention span, and just plain don't think very well.
