Not directly, no. Belief, it seems to me, isn’t something that one can just choose to change. To use an analogy relating to preference, if one prefers chocolate over vanilla, one can’t just decide to like vanilla more. One could choose to stop eating chocolate and/or have more exposure to vanilla and maybe over time, due to these different experiences, that preference will change. Or maybe not.
Similarly, if one believes in a god or gods, or one doesn’t, one cannot just choose to believe different. One can take action to expose oneself to an opposing belief, like an atheist attending various religious services, doing meditations and rituals and prayers, reading from various spiritual leaders, etc. But it seems to me belief, in this sense, necessarily has (or lacks) some experiential aspect that can’t be simply chosen or reasoned into or out of.
So, my point being, intelligence, or more precisely curiosity, encourages one to increase the breadth of one’s experience and exposure and evaluate it with as minimal bias as possible.
Religion and theism are not the same thing. Atheism is the opposite of theism, by definition, but not of religion. Thus while one that rejects theism is necessarily an atheist, one can reject religion without rejecting theism and, thus but not necessarily be an atheist.
I think it’s fair to say that we recognize causality and it’s typically a helpful adaptation to make causal links, even if flawed. Consider an ancestor in the woods and hears a random rustling in the leaves, if he assumes it’s dangerous and is wrong, no big deal, but if he ignores it, it’s bad. This of course led to us attributing aspects that we couldn’t easily explain to SOMETHING and is likely how religion first formed.
That said, I don’t think intelligence is fighting against that as much as directing it. After all, is not science itself about finding causes? We know lightning or earthquakes aren’t caused by angry deities but by complex meteorological or geological processes.
But then again, for plenty of people, understanding the precise reason behind some things isn’t that important, unless it has impact on our decisions. As in, when someone wants to use his phone to access the internet, whether they understand all the technological underpinnings or think it’s powered by invisible elves, unless they think they need to behave one way for one explanation and differently for the other, it doesn’t matter. However, it would obviously be comically awful if a smartphone engineer believed the same thing.
And in that, we’re ALWAYS going to be stuck with gaps in our knowledge that we will explain away or glass over to some degree. Even in science, for example, we don’t know what dark matter or dark energy are, though we have some candidate possibilities, instead we accept the unknown until such a time that it is known or an alternate even more accurate theory supersedes it. As long as some people continue that investigation and we don’t just write it off as unknowable, which is ultimately the danger of dogmatic explanation, not limited just to religion. Unless we can prove something is unknowable (a famous example being the halting problem), but even then we at least have certainty that it’s unknowable rather than just an assertion.
Ultimately, it seems to me that intelligence, it this case, is best defined by that insatiable curiosity that black boxes or god of the gap types of explanations aren’t satisfactory. This sort of curiosity makes the sorts of gods of our ancestors largely or completely unnecessary for whatever their initial explanatory purpose was, but then, I wonder, are we not just replacing those anthropomorphizations as deities with more abstract concepts detached from ritual and dogma?
