Do We Choose Our Beliefs?

Steve Perry asks:

Hey Spencer,

           Where do you get the idea that we do not choose our beliefs?

Steve

My answer:

Beliefs are formed at a preconscious level, and seem to be tied up in the region of the brain (ventromedial prefrontal cortex) that pertains most to sense of self. Beliefs can change, but only as the sense of self is altered by the environment and new information. We're incapable of changing our minds simply based on new information; the new information also has to relate in some preconscious way to our survival instinct. A good example is this: on a conscious level, I know there are no ghosts in my house. On an instinctual, preconscious level, however, there may be a stronger subconscious belief that will present itself after I've watched The Exorcist at one o clock in the morning and am home alone.

Within any given context individuals only have so many variations of things that they can believe and ways they can behave. We are capable of changing these ways, but external factors have to be conducive to such changes, and must apply enough internal pressure to create the impetus for change.

My definition of faith is derived from this understanding. It is the desire to attain or preserve a belief that is in flux by creating an environment that is conducive to the creation or preservation of that belief. True beliefs do not require such safeguarding and reinforcing. My belief in gravity requires no assistance. Gravity is consistent in almost every Earthbound environment. My belief in Marxism, however, does require a certain amount of reinforcement, because there is enough historical evidence and contrary opinion out there to force me to entertain doubts about it. The same goes for my atheism: it has to be something I consider on a conscious level. It too requires reinforcement. As does your religious faith and political ideas.

At least that's my understanding. We can also probably get into a discussion about free will, but I'm in much shallower territory there.
