Have you seen this sequence? It reveals how the LDS church gets things done: By providing a real community for its members, and making them feel like they belong by giving them responsibilities. I'm sure an aspiring-rationalist version of that would be even better.
This is the super-secret rationality technique of churches. It's the reason religious people are happier than nonreligious people in the US. It's the domain where religious people are correct when they say that nonreligious people are missing out on something good. Now we just have to implement it. It's not something that we can do individually.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
(I plan to make these threads from now on. Downvote if you disapprove. If I miss one, feel free to do it yourself.)
