There is this story that I thought of when I originally read this. it can be found here. Like me, most of you who go through the link and read the speech will find obviously sub-optimal thinking. You will think "If it were an option of following this principle or not, I could not follow it. Even if I have no other principle to replace it with, I could not, in good conscience, accept this idea." This is were your rationality will destroy any group you try to create. If you cannot allow any sub-optimal parts in the organizations you participate in, then you will never participate in an organization of humans. The example I picked comes from a religious and irrational organization like Eliezer described, but it actually works, unlike co-ops of large groups of rationalists who refuse to accept sub-optimal planning in any form. So in this instance, Religion has a better policy than rationalists and, until you find an empirically proven policy that does better, you would do better to adopt it.
