Oh I see. Well, maybe I'm generalizing from one example here, but usually when I dance or sing with people, my only conscious purpose is to have fun. That means that I participate in such activities when I feel like having fun. I think I had all the information necessary to come to the conclusion "singing and dancing is a way to get closer to people" before I read this post, but I never executed on it. Now that I've read this post, I can choose to seek out the people I want to be closer to and get them to dance or sing with me. Also, if I'm already dancing or singing with people, I will notice what's going on and consciously decide to grow closer to them or to keep my distance. (And if I don't consciously decide, I might unconsciously decide that I must want to be closer to them since I'm singing with them, via cognitive dissonance resolution.)

I believe we've both been to meetups that involved chanting. If other people are like me, more extensive chanting will be an easier sell for some. (And others will realize that they don't really want to grow closer.) But maybe I'm wrong and I was the only one at that meetup who hadn't had this epiphany yet.
