It is often claimed that the religiosity of Americans is on a downward trend. While there are lots of reasons to be doubtful of this basic premise, a narrower context makes it much more convincing. Consider instead the premise that the religiosity of educated 20-30 somethings is on a downward trend. By religiosity, I mean religious belief, participation, and affiliation. This premise seems much more believable. I have no factual scientific research supporting this premise nor do I intend to perform such research. If anyone feels like enlightening me, feel free, but for my purposes here it is fine to merely assent to such a premise.
I take it that this premise is often asserted to give credence to a variety of non-theistic points of view. The premise-invoker is saying, essentially, "The majority of your peers disagree with you and agree with me. Furthermore, my numbers are growing. Why should I bother dealing/listening to the likes of you?" Without disagreeing with this general idea of reasoning, that a majority rule can be a proper reason for belief, I would like to provide a different defense.
People believe ideas for lots of reasons, and we perhaps give too much credence to the idea that truth is the primary one. There may be many other factors.
Consider the Law of Demand. This economic idea is simply that as price increases, demand decreases. Let's apply this rule somewhere it doesn't belong, like religiosity.
Our culture has gotten busier, more diverse, and just generally more complicated. People are involved with a myriad of activities with little time for thorough reflection. Our culture has many various religious beliefs. There are more areas of knowledge of which one is expected to have a basic grasp. All of these impose a cost on religious belief and religious exploration. Religiosity involves waking up and going somewhere on Sunday morning and staying involved with another social network. It at least involves taking religious claims seriously, attempting to understand them, and exploring varied views on important and complicated subjects of human nature.
So, perhaps religiosity has decreased simply because the 'cost' has gone up. In other words, the reason for a decreased religiosity may have little to do with a growing consensus that religious belief is untrue and/or irrational, but rather have more to do with other surrounding costs. THEN, in order to feel more justified about forming beliefs based on these other costs, people form beliefs about the truth or irrationality of religious belief.
In fact, applying this view to epistemology generally, I think the truth of an idea is perhaps only one small factor of belief for most people. So long as the belief is debatable and reasonable, as most metaphysical, political, and moral beliefs are, than the truth of it seems to impose little cost on my believing it. While the discussions in these areas at least superficially appears to be a debate about truth, one might think the real reasons for belief are related instead to one's family ties and emotions, happiness related to the belief, a sense of moral righteousness the belief may impose, and perhaps other side-benefits.
I'm left with 4 questions.
1. Would a more thorough version of this sketch suggest an adequate response to the secularization-premise invoker?
2. SHOULD people form their beliefs considering only the truth of said belief, or does it seem fine to form beliefs based on these other costs?
3. Is the narrow version of the secularization-premise correct? While the broader version seems to be unpopular now, the narrower version I have laid out here seems reasonable and often accepted.
4. Should I keep my nose out of any cross-disciplinary work in the future?
