Because of this string determination that the Bible is ALWAYS right, regardless of evidence, even if it says up is down and black is white, they don't find it necessary to do research into science. If the Bible says it's wrong, it's wrong - and any evidence to the contrary is either a test of faith from God, the work of the Devil, or "fallen man" trying to interpret things he can't possibly understand. Or maybe all 3. In any case, research is irrelevant if the Bible is assumed to be always true by default.
[going to make some big generalisations and oversimplifications now..]
It always kinda reminds me of the whole history of how science came into existence (or rather, was lacking
before it came into existence). Before the 1500's - 1600's, people were just as intelligent as we are. Still, it didn't produce anything much of progress or worthwhile knowledge because some ingredients seemed to be missing. Somehow, there was this idea that the Bible was... "enough". The concept that something could be learned about natural phenomenons/objects by
observing them (
questioning them, like by doing experiments) seemed to be in a "judo hold" by a reigning absolute trust in Divine Revelation. It was not a case of scientific endeavour being beyond their mental capacities. But more a matter of, if we talk in terms related to your question, not
acknowledging the need or possibility to learn.
This seems to be mimicked on a personal level by (certain types of) religious fundamentalists. They have the Bible. That is simply enough to them, and they certainly can do WITHOUT anything that
threatens the very reason why they can get along with a limited, simplistic (easily to overlook and therefore consoling) concept of reality.
I also always feel like these kind of people have no concept of how fallible we intrinsically are; skepticism and science go hand in hand, and the scientific method I'm sure is partly the result of recognising human's unlimited capacity to self-delude. Only if you recognise that weakness, you understand that somekind of methodology that helps to eliminate this as much as possible, is necessary. And to be preferred over "intuition" (at least generally ;-) ),"predictive dreams" and "Divine Revelations". Extreme naivety in that department seems to be widespread in certain fundamentalist circles...
