You may see a counsel of elders running an elite group of intellectuals.. but emotionally and behaviorally, we rarely progress past here. Classroom management. You can whittle down the class to only the well-behaved students if you like, but you might miss out on novel perspectives from those who don't fit in the bell curve of expected norms. But this is my bias. I'm just expressing my pov. I tend to favor the weird people and give them extra attention rather than excluding them, because I find the normies can usually manage themselves just fine. But I'm not volunteering either, just expressing smile emoticon
