I've been thinking a lot about belief (any kind). Specifically, why do some of us (myself included at times) refuse to stop believing in a concept or idea, even when there is irrefutable proof laid out in front of us? I am thinking largley from the point of view of "theory". It takes a lot to change my mind about something, yet some people can just read up on a different idea and discard their old belief in an instant, and can do this several times over.
I am curious about perspectives on belief and what it means to us as a concept, rather than any specific type (scientific, religious or political).
There is a lot to the way the brain works. Nerve cells use up more oxygen than most other cells- because they are always active. Which nerve cell becomes triggered by a series of others depends on several things, and it can be a different path each time. It takes several stimulations, on several dendrites simultaneously or one one repeatedly, to actually trigger one neuron. In terms of firing, a neuron is on or off, there is no strong/weak scale, but it must reach a certain level of electrical imbalance to trigger.
Repression is one aspect of human psychology about which Freud was dead-on. Of course, there is no particular "part of the brain" that is "The Unconscious", but lots of the processes that take place are unconscious- in that you don't recall them. Unconscious should be used as an adjective, not a noun. Anyway, when something happens that would normally remind you of some past event, if that event was particularly unpleasant, you will find other things to think about, other things to be reminded of, that often imitate the traumatic experience enough to replace it, but without confronting the fear caused by the memory.
After this substitution is made enough times, whatever pathway is associated with it will become stronger than the original, so it will be triggered more easily.
Meet the fetish.
Check out this guy's perspective:

Supposedly the most intelligent person ever. He refers to situations, which I've also experienced, where a random memory pops up in the consciousness. But if you retrace your steps, sometimes it was not random, and you find the associations that led to it *were actually conscious* when you thought through them.
Another important part of the question is what Freud called "preconscious". The name of your first pet was in your preconscious awareness until you read this, now it's conscious. It refers to stuff that is not inaccessible, but also not on your mind. I think this factors into people clinging to beliefs or believing two contradictory things. You just aren't thinking about one of those beliefs when you're thinking about the other.
Lots of people, for instance, talk about how selfish and oblivious the opposite sex is, while members of that sex who aren't like that are all around them, even their best friends. If the contradiction is pointed out, they will say "Well not you," but the belief remains unaffected.
I think stuff like this is common enough to indicate the purpose of understanding isn't to perfect itself, but to guide the decision-making process.
