Authoritarianism

"A foolish faith in authority is the worst enemy of truth." -- Albert Einstein, letter to a friend, 1901

[25% of the population, according to Bob Altemeyer are authoritarian followers, more or less impervious to reasoned arguments.  They must tally with the Stage 1 and 2 spirituality.  They follow without thinking the Authoritarians The Followers, as characterized by Altemeyer: are “especially submissive to established authority;" show “general aggressiveness” toward others when such behavior “is perceived to be sanctioned” by established authorities; are highly compliant with “social conventions” endorsed by society and established authorities.  In Pharma land these can be found among the Quackbusters (eg HealthFraud posse) who are organised and lead by Authoritarian leaders (eg Smith).  These are the people who vote in the Social dominators and support their wars, and if you wondered who buys Tony Blair's autobiography here is the answer!]

Quotes
Probably about 20 to 25 percent of the adult American population is so right-wing authoritarian, so scared, so self-righteous, so ill-informed, and so dogmatic that nothing you can say or do will change their minds. They would march America into a dictatorship and probably feel that things had improved as a result. … And they are so submissive to their leaders that they will believe and do virtually anything they are told. They are not going to let up and they are not going away. Bob Altemeyer

I am convinced that at least a third of the population is what Eric Hoffer calls "true believers." They are joiners and followers . . . people who want to give away their power. They look for answers, meaning, and enlightenment outside themselves. ....They are followers, not because of a desire for self-advancement, but because it can satisfy their passion for self-renunciation!" Hoffer also says that true believers "are eternally incomplete and eternally insecure"! ......The Moral Majority is made up of true believers. All cults are composed of true believers. You'll find them in politics, churches, businesses, and social cause groups. They are the fanatics in these organizations. The Battle for Your Mind: Brainwashing Techniques Being Used On The Public By Dick Sutphen

“The men the American people admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth.” Henry Louis Mencken (1880-1956), American humorous journalist

“The masses have never thirsted after truth. Whoever can supply them with illusions is easily their master; whoever attempts to destroy their illusions is always their victim.” Gustave Le Bon, “The Crowd”

“The statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception.” Mark Twain, “The Mysterious Stranger” (1910)

"They must find it difficult...those who have taken authority as the truth, rather than truth as the authority."---Gerald Massey

Patriot: the person who can holler the loudest without knowing what he is hollering about. ---Mark Twain

"The men the American people admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth."-H. L. Mencken

"It is more than just gullibility that explains the phenomenon of the authoritarian follower. Can you imagine John Yoo, Alberto Gonzales, or David Petraeus going against the will of George W. Bush on any matter when he was in power? That would be highly unlikely because their positions of high power depended entirely on putting all their energy into anticipating the needs of and pleasing their “leader”. George Bush started out the same way. As governor of Texas, all his efforts went into pleasing his corporate cronies. In return, they rewarded him handsomely by ensuring his material wealth and serving as a power base for his climb to the presidency. Lobaczewski describes the process as one of sycophancy: "They initially perform subordinate functions in such a movement and execute the leaders’ orders, especially whenever something needs to be done which inspires revulsion in others. Their evident zealotry and cynicism gives rise to criticism on the part of the more reasonable members, but it also earns the respect of some its more extreme revolutionaries. They thus find protection among those people who earlier played a role in the movement’s ponerization, and repay the favor with compliments or by making things easier for them. Thus they climb up the organizational ladder, gain influence, and almost involuntarily bend the contents of the entire group to their own way of experiencing reality and to the goals derived from their deviant nature."

Experiments show that high RWAs are so defensive and so unaware of themselves that when you tell them what high RWAs are like, they almost always think you're talking about somebody else. So I predict most authoritarian followers would sail right through this book and compartmentalize, misinterpret, rationalize, and dogmatically deny it had anything to do with them personally. If you tried to force this self-awareness on them, they would probably run away, run away, as fast as they could. So good luck if you passed on this URL to your fascist Uncle George.
.......I similarly think you'll likely be wasting your time trying to convince authoritarian followers that they are being systematically misinformed and played for dopes by their leaders. It's too important to them to believe otherwise, and just your raising the question will likely put you into their huge out-group and make them suspicious of you. p.239 [2006] The Authoritarians” by Bob Altemeyer

They (religious fundamentalists) are highly likely to be authoritarian followers. They are highly submissive to established authority aggressive in the name of that authority and conventional to the point of insisting everyone should behave as their authorities decide. They are fearful and self-righteous and have a lot of hostility in them that they readily direct toward various out-groups They are easily incited, easily led, rather un-inclined to think for themselves, largely impervious to facts and reason, and rely instead on social support to maintain their beliefs. They bring strong loyalty to their in-groups. have thick-walled, highly compartmentalized minds, use a lot of double standards in their judgments, are surprisingly unprincipled at times, and are often hypocrites.
    But they are also Teflon-coated when it comes to guilt. They are blind to themselves, ethnocentric and prejudiced, and as closed-minded as they are narrow-minded. They can be woefully uninformed about things they oppose, but they prefer ignorance and want to make others become as ignorant as they. They are also surprisingly uninformed about the things they say they believe in, and deep, deep, deep down inside many of them have secret doubts about their core belief. But they are very happy, highly giving, and quite zealous. In fact, they are about the only zealous people around nowadays in North America which explains a lot of their success in their endless (and necessary) pursuit of converts.
    I want to emphasize also that all of the above is based on studies in which, if the opposite were true instead, that would have been shown. This is not just "somebody's opinion." It's what the fundamentalists themselves said and did.  And it adds up to a truly depressing bottom line. Read the two paragraphs above again and consider how much of it would also apply to the people who filled the stadium at the Nuremberg Rallies. I know this comparison will strike some as outrageous, and I'm NOT saying religion turns people into Nazis. But does anybody believe the ardent Nazi followers in Germany or Mussolini's faithful in Italy or Franco's legions in Spain were a bunch of atheists? Being' religious" does not automatically build a firewall against accepting totalitarianism, and when fundamentalist religions teach authoritarian submission, authoritarian aggression, and conventionalism, they help create the problem. Can we not see how easily religious fundamentalists would lift a would-be dictator aloft as part of a "great movement," and give it their all? [Book 2006] The Authoritarians” by Bob Altemeyer

When bad news spills out about things that high RWAs support, they want to be told it isn't true. So some governments have gotten used to issuing "non-denial denials" and flimsy counter-arguments, because that's all it takes and it's so effortless. If a well-researched paper by a prestigious scientific body concludes that human activity is seriously increasing the amount of carbon dioxide in the atmosphere, culprit governments will say "the evidence is incomplete" and they will find someone, somewhere, with some sort of credentials, who will dismiss a great number of studies with a wave of the hand and give them the sound-bite they want.
    When someone responds to evidence with "a wave of the hand" or a bland dismissal like "It's just nonsense," they're usually revealing they can't say anything more specific because they're whupped. But the government's supporters will be reassured. For them, one sound bite cancels the other, and there really is no difference between a widely-confirmed fact and a speculation, between fifty studies and one.
    To take a non-political example of walking extra miles for authorities, when people first began to reveal they had been sexually assaulted as children by priests and ministers, bishops often issued statements saying they had thoroughly investigated the charge and found it had no merit. That was good enough for the authoritarian followers. .....If it eventually became known that the bishops' own inquiries had discovered that Father X was indeed a pedophile, but the bishops still denied he was and sometimes even quietly transferred Father X to another parish, where he sexually assaulted still more children, do you think the high RWAs learned anything from this? How many "disconnects" do you think they have at hand to avoid realizing they allowed themselves to be deceived? [Book 2006] The Authoritarians” by Bob Altemeyer

Once someone becomes a leader of the high RWAs' in-group, he can lie with impunity about the out-groups, himself, whatever, because he knows the followers will seldom check on what he says, nor will they expose themselves to people who set the record straight. Furthermore they will not believe the truth if they somehow get exposed to it, and if the distortions become absolutely undeniable, they will rationalize it away and put it in a box. If the scoundrel's duplicity and hypocrisy lands him on the front page of every daily in the country, the followers will still forgive him if he just says the right things. [Book 2006] The Authoritarians” by Bob Altemeyer p.100

And while most Americans came to realize what a mistake the war in Iraq has turned out to be, high RWAs lagged far behind. They listen to the news they want to hear. They surround themselves with people who think like they do. They believe the leaders who tell them what they want to be told. They make about as much effort to get both sides of an issue as the Bush administration does to foster different points of view within the White House. And if six high RWAs are sitting in a room talking about the war, and all six now have misgivings, it will still be hard for any of them to say so because the ethic of group solidarity is so strong in the authoritarian mind.
    Is there any conceivable evidence or revelation that will lead them to admit the war was a mistake? I suspect some of them will eventually, begrudgingly reach that point, and others will rewrite their personal histories and say they had their doubts from the start. But others, petrified by their dogmatism, will never admit the undeniable.  [Book 2006] The Authoritarians” by Bob Altemeyer p.99

It's easy to see why authoritarian followers would be dogmatic, isn't it? When you haven't figured out your beliefs, but instead absorbed them from other people, you're really in no position to defend them from attack. Simply put. you don 't know why the things you believe are true. Somebody else decided they were, and you're taking their word for it. So what do you do when challenged?
    Well first of all you avoid challenges by sticking with your own kind as much as possible, because they're hardly likely to ask pointed questions about your beliefs. But if you meet someone who does, you'll probably defend your ideas as best you can, parrying thrusts with whatever answers your authorities have pre-loaded into your head. If these defenses crumble, you may go back to the trusted sources. They probably don't have to give you a convincing refutation of the anxiety-producing argument that breached your defenses, just the assurance that you nonetheless are right. But if the arguments against you become overwhelming and persistent, you either concede the point—which may put the whole lot at risk—or you simply insist you are right and walk away, clutching your beliefs more tightly than ever. 
    That's what authoritarian followers tend to do. And let's face it, it's an awfully easy stand to take. You have to know a lot nowadays to stake out an intelligent, defendable position on many issues. But you don't have to know anything to insist you're right, no matter what. Dogmatism is by far the best fall-back defense, the most impregnable castle, that ignorance can find. It's also a dead give-away that the person doesn't know why he believes what he believes. [Book 2006] The Authoritarians” by Bob Altemeyer p.93

There are people who talk about God but are not the least bit religious or spiritual. These are people who may appear to be in Stage Four, who can wear Stage Four veneer— like certain cult leaders—but who, in fact, are Stage One criminals.-----THE STAGES OF SPIRITUAL GROWTH By M. Scott Peck, M.D.

Stage One, which I label "chaotic/antisocial." This stage probably encompasses about twenty percent of the population, including those whom I call people of the lie. In general, this is a stage of absent spirituality and the people at this stage are utterly unprincipled. I call it antisocial because while they are capable of pretending to be loving, actually all of their relationships with their fellow human beings are self-serving and covertly, if not overtly, manipulative.-----THE STAGES OF SPIRITUAL GROWTH By M. Scott Peck, M.D.
