I'm guessing by "people with such a large variety of world views" you mean "diverse groups with varying world views". But even if not, you might be surprised to find how simple these religious frameworks are at their core, and how much they really do allow a variety of world views within a single religion. There is plenty of surface area, so to speak, within something like a world religion, to which can be attached any amount of science. Science is of course just human psychology with certain conditions fuzzily applied, so for example, when adding religion into the mix, it helps to look at science as a convergence of modeling (soft sci) and measuring (hard sci).
I haven't been a Muslim or a Buddhist, but I was a Mormon missionary who taught Buddhists of many sects, plus South American Catholics, European atheists, Muslims, Raelians, and your odd Yakuza while I lived in Japan.
I was taught to respect these people for what they had already learned and experienced, and to teach them a simple, elegant model of my belief system. In studying that model I realized that I hold and have the responsibility to shape, apply, and evaluate multiple models of my religion through my own life experience. This becomes an ever-evolving science that is in principle one and the same with the more technological science posted here. There are deeper qualitative questions and experiential aspects and anecdotes that are really more like fractals than questions, open to broad and deep exploration. But those elegant models, the simple ones--right in there you have a huge amount of religious people who really don't differ much from your complete-opposite anecdotal scientist in the important ways.
I could go right now and google reasons why Mormons and science don't mix, or I could go out and find a Mormon who would argue with most any scientist (come to think of it, my Mom is a good one!), but the boundaries there are in the end just different from my own and I find there's absolutely room for that. I hold my own models lightly, and compare them with others' from time to time. But--and I doubt I'm some freak religious exception here--nobody is dictating my models and their composition / combination to me. I act in many ways in respect to my church like a robot (Sunday? Church!), not because I have to, but because in my mind, the overall experiment is yielding good results and I'll change variables as I need to when I examine them. I got the feeling that others in other religions act and feel basically the same way. As I mold my models I think of myself as a type of scientist, and hope any scientist would consider the study of religion from a scientific view (model all the time, measure what you can) as an absolute (and hopefully enjoyable) mandate.
The wonderful intellectual fruit you speak of is something I experienced first hand when I was a BYU student. As a teenager I was told how wrong evolution was by my dad (an extremely educated man himself with multiple degrees), heard how certain it was from my sunday school teacher (a respected surgeon), and then I went off to my BYU biology class and was immediately taught about talk.origins and told "hey if you guys (freshmen) don't believe in evolution that's fine, but at least educate yourself". This was a huge faith-strengthener to me; a diversity of models is not only OK but developing one's own educated models was seen as wisdom in a nutshell.
