If you find this thread interesting, those books go into much greater detail and are highly recommended. I'll provide a link to the Amazon page for each at the bottom of this post.
In 1957, social psychologist Leon Festinger spent a few months living with a UFO doomsday cult whose leader was preaching that the world would be ending on a specific date in 1957. A hardcore group of about 30 cult members had sold all of their personal possessions and were living in the house with their leader, awaiting the final destruction of the earth. Festinger wanted to find out what happened to those people when, as he correctly predicted, the prophecy did not come to pass.
On the night of the end of the world, midnight passed as it always did and for several hours the cult members wandered around as if in a daze. And then, something strange happened: A feeling of absolute joy and elation filled the crowd. One by one, they all came to the conclusion that their faith and prayers had prevented the disaster. None of them renounced the cult or their leader, in fact
they believed in the cult even more strongly than before their prophecy had failed to come true. In another interesting twist, Festinger observed that those cult member who had
not sold their possessions and moved into the compound were able to accept their mistakes and move on with their lives. (

Human beings have evolved over time in such a way that it is difficult for us to admit errors. Our brain is hard-wired to react to dangers on the periphery before we are even conscious of seeing them. One can readily see how this would be advantageous; If a tiger appears in our peripheral vision, would our ancestors have been better off reacting instantly (by fleeing or taking cover) or by waiting for our brains make absolutely certain it was a tiger before we took action? Obviously, for our ancestors, a second or two could have meant the difference between passing his/her genes on or not. There is a fairly obvious implication in this for us today: sometimes, it is NOT a tiger that we see in the periphery. However, often we have acted before we know the truth.
It also was evolutionarily advantageous for our ancestors not to question our own image and opinions. Again, in mere seconds of self-doubt, we could lose our possessions, our mate, or our lives to a rival. It was best for us to be completely sure of ourselves, and to be able to defend ourselves and our beliefs without any dangerous self-doubt.
Of course, our world is very different now than it was thousands of years ago, and what was once an evolutionary advantage has become very troublesome. To extend the metaphor, we can be tricked pretty easily into believing that objects on the periphery are something that they are not. And once we have made our decisions, it is extremely hard for us to admit that we are wrong.
In order to reduce dissonance, we tend to act in ways that are illogical and irrational. And as Festinger's study shows, the more heavily invested we are in a particular belief, the more important it is for us to reduce dissonance.
I'll give you a personal example. I have been on DU for 5 years, and over that time I have learned to hate a particular DUer. In my mind, he is the the exact opposite of me: he is insensitive, callous, and pompous. I have known this individual for years, so I have a lot of time invested in this belief, and, as I see him as my polar opposite, I have my own personal identity wrapped up in it. Whenever this individual posts something, my immediate reaction is to dismiss and criticize what he has said. This reaction happens before my brain even has time to process what he has said. In essence, it doesn't even matter what he says; if it turns out to be a statement I agree with, I'll question his motives or his veracity. Cognitive dissonance keeps me from hearing or accepting anything that this person says.
What are the implications of the study of cognitive dissonance or DU in general, and GDP in particular? Well for one thing, if you have been supporting Hilary Clinton or Barack Obama since the beginning, since there were 8 Democratic candidates in the race, you are extremely unlikely to change your mind now. If your candidate should happen to make a mistake, or be caught in a lie, you will reduce the dissonance this creates anyway that you can: You will say that the other candidate lies too, and his/her lies are worse; You'll characterize the opponent's supporters as irrational, stupid, or downright evil; or you'll do the online equivalent of plugging your ears and whistling loudly.
This is why there are so many posts complaining that the other side are vicious, ignorant, evil Republican trolls. This is why the most hardcore supporters from each side claim that they will not vote for the other candidate in the general election, even though that goes against all logic. Once you have decided that your candidate is the one, and your opponent is evil, you will do all you can to reduce the impact of dissonant information.
The effect of cognitive dissonance is the same whether your candidate is Barack Obama or Hilary Clinton. It would have been the same if your candidate was Joe Biden or even Ralph Nader. However, there is a reason why this primary in particular has become so vicious, so petty, and so divisive. Ironically, this has to do with the fact that the remaining candidates are so similar.
