Perhaps. I would not care to speculate about intellect. I imagine though that the underlying
reasons they choose to congregate are more or less the same reasons that people in other religions congregate. Allowing of course some leeway for the fascination with the 'new'
Humans have a need to 'find meaning' in things. And once they find some, they look for yet more. Which is why ironically many atheist organizations are now looking towards codifying their belief system with 'commandments'

I have no problem with the idea in and of itself. I just wish people could look at the merits of the principles on their own face as opposed to assigning them to a 'larger source'. Here are some of my favorite rules to live by for example:
Don't give unsolicited advice.
Show people respect, particularly when in their home.
Do not complain about anything to which you need not subject yourself.
Don't kill animals unless you are attacked or for food or shelter.
Don't bother people. If people bother you, ask them to stop. If they don't, kick their ass.
Don't harm young children
For what its worth- those are 6 of the 11 Satanic rules of the earth.
