Consider two facts:
- People with religious beliefs, and associated behavior, consistently tend to have better lives. It seems that religious folks tend to be happier, live longer, smoke less, exercise more, earn more, get and stay married more, commit less crime, use less illegal drugs, have more social connections, donate and volunteer more, and have more kids. Yes, the correlation between religion and these good things is in part because good people tend to become more religious, but it is probably also in part because religions people tend to become better. So if you want to become good in these ways, an obvious strategy is to become more religious, which is helped by having more religious beliefs.
- Your far beliefs, such as on religion and politics, can’t effect your life much except via how they effect your behavior, and your associates’ opinions of you. When you think about cosmology, ancient Rome, the nature of world government, or starving folks in Africa, it might feel like those things matter to you. But in terms of the kinds of things that evolution could plausibly have built you to actually care about (vs. pretend to care about), those far things just can’t directly matter much to your life. While your beliefs about far things might influence how you act, and what other people think of you, their effects on your quality of life, via such channels of influence, don’t depend much on whether these beliefs are true.
Perhaps, like me, you find religious beliefs about Gods, spirits, etc. to be insufficiently supported by evidence, coherence, or simplicity to be a likely approximation to the truth. Even so, ask yourself: why care so much about truth? Yes, you probably think you care about believing truth – but isn’t it more plausible that you mainly care about thinking you like truth? Doesn’t that have a more plausible evolutionary origin than actually caring about far truth?
Yes, there are near practical areas of your life where truth can matter a lot. But most religious people manage to partition their beliefs, so their religious beliefs don’t much pollute their practical beliefs. And this doesn’t even seem to require much effort on their part. Why not expect that you could do similarly?
Yes, it might seem hard to get yourself to believe things that seem implausible to you at the moment, but we humans have lots of well-used ways to get ourselves to believe things we want to believe. Are you willing to start trying those techniques on this topic?
Now, a few unusual people might have an unusually large influence on far topics, and to those people truth about far topics might plausibly matter more to their personal lives, and to things that evolution might plausibly have wanted them to directly care about. For example, if you were king of the world, maybe you’d reasonably care more about what happens to the world as a whole.
But really, what are the chances that you are actually such a person? And if not, why not try to be more religious?
