I agree that religious organizations have developed many effective techniques for getting certain kinds of things done, and I endorse adopting those techniques where they achieve goals I endorse.

I'm not sure I agree that this isn't already happening, though.

Can you provide some examples of such techniques that aren't also in use outside of the religious organizations that developed them?

Incidentally, the word "rationality" seems to contribute nothing to this topic beyond in-group signalling effects.
