This is a piece of wisdom that many don't really want to think about. We'd be more inclined to go with groups that we can say yes to and expect they'll say yes to us back. This is rooted from our need to belong and survival in groups. Conform or get casted out by the tribe to fend for yourself in the wild. Naturally, group thinking has its own hazards of being an echo chamber but I'm not really the one that needs convincing that people need to reflect on their ways of interacting with their social circle. Go where there is friction to test one's beliefs I say.
