Our belief systems are based on foundation premises. Like the foundation of a house, these fundamental premises of our belief systems supports all the weight of the house; our belief system. A few facts may have an affect on one room in that house but, that alone may not alter the foundation, so the house remains as is. One can spackle the cracks, but not have to change anything.That's not the thrust of the article though.
This is about how, and to some extent why, we disregard facts in favour or opinion. And it cites very interesting studies demonstrating just how unimportant facts are in relative terms.
Questioning one's own foundation premises is not an easy thing to do, since foundation premises take time to build and may not even be conscious, since they may have evolved over a long time, beginning many years ago.
For example, science and evolution can show that human DNA goes back millions of years. This fact is often used to discredit the stories of Genesis, which claim a smaller time window. However, one of my foundation premises, based on many years of research into consciousness and the unconscious mind, believes that Genesis is not talking about DNA, but about modern consciousness and the evolution of the modern ego.
For example, through will and choice, I can take steroids and lift weights to turn a body with DNA, that says I should weight 140 pounds, into a muscular body that weighs 240 pounds. This is mind over matter, that the DNA alone, could not explain, if we saw that 240 pound body; end result, and had some of the person's DNA. Consciousness and will can explain this, with consciousness, above the DNA in terms of hierarchy and priority. We can will to be unnatural, through collective learning.
Those facts of million year old human DNA are not relevant to me. This is more relevant to those with a retro foundation that assumes DNA can tell us all. This is why discussion of the facts of the ego and inner self can't get through. Science is still stuck at 1950's; discovery of one size fits all DNA. Advancing foundation premises is not that easy since if the foundation cracks, the weight above cannot be further expanded.
