Maybe you mean onus? And no, it isn't because that's exactly the sort of thinking that keeps the field as non-diverse and exclusionary as it is. What you're describing isn't some sort of property of an effective team. It's one of a hostile workplace.

That's where we disagree. All effective teams are exclusionary; I've never seen an effective team chosen by lottery tickets. And effective intra-team communication is their most defining trait. In my experience, so long as diversity does not impede communication, it is a neutral trait (neither positive nor negative correlation).

Not having a discriminatory environment is not the same as 'chosen by lottery ticket'. And for certain classes, having it is against the law no matter whether you feel it's neutral or chaotic or whatnot.
