Bob Altemeyer's - The Authoritarians
http://home.cc.umanitoba.ca/~altemey/For example, take the following statement: “Once our government leaders and the authorities condemn the dangerous elements in our society, it will be the duty of every patriotic citizen to help stomp out the rot that is poisoning our country from within.” Sounds like something Hitler would say, right? Want to guess how many politicians, how many lawmakers in the United States agreed with it? Want to guess what they had in common?
Or how about a government program that persecutes political parties, or minorities, or journalists the authorities do not like, by putting them in jail, even torturing and killing them. Nobody would approve of that, right? Guess again.
Don’t think for a minute this doesn’t concern you personally. Let me ask you, as we’re passing the time here, how many ordinary people do you think an evil authority would have to order to kill you before he found someone who would, unjustly, out of sheer obedience, just because the authority said to? What sort of person is most likely to follow such an order? What kind of official is most likely to give that order, if it suited his purposes? Look at what experiments tell us, as I did.
The studies explain so much about these people. Yes, the research shows they are very aggressive, but why are they so hostile? Yes, experiments show they are almost totally uninfluenced by reasoning and evidence, but why are they so dogmatic? Yes, studies show the Religious Right has more than its fair share of hypocrites, from top to bottom; but why are they two-faced, and how come one face never notices the other? Yes, their leaders can give the flimsiest of excuses and even outright lies about things they’ve done wrong, but why do the rank-and-file believe them? What happens when authoritarian followers find the authoritarian leaders they crave and start marching together?
