Religions are a lot more than just codified traditions, but yes, some traditions are have benefits. That doesn't mean that the religion as a whole is good at predicting anything, it just means that they occasionally preserve things that are beneficial. But because w…
> But because what is codified is codified without systematic knowledge of what works or how it works, the preservation of benefit is essentially random with weak selective pressure acting in the aggregate of beliefs But you agree this must be much better than random? Evolutionary pressure on species is also rather weak: unfit specimen survive and fit specimen die due to chance all the time. But look where it got us…
Well, no, without a definition of what domain it is supposed to be better in, and what the actual alternative it is being compared to more concretely than "random" (irreligious humans don't behave randomly, and, in fact, even without religion preserve traditions, some of which are useful), and probably some argument to make the case, no, I'm not going to agree with that.
> You definitely don't have to understand "how it works" to be able to make good predictions.
You have to actually make predictions to make predictions, certainly. And religion is manifestly very bad at making predictions where it does make them, and the things you are talking about are very much not predictions, they are memes in the original sense.
