Aggressive personalities aren’t the same as strong personalities, in precisely the way status trinkets aren’t class.
I’d say strong personalities are essential for consensus:
When it’s clear who is holding court, there’s much less talking over each other and bickering, precisely because the leader has made it clear what the expectation is — and everyone knows it will be enforced.
“Let’s quiet down for a moment, I really want to hear what @edmundsauto is saying.”
It also kinda makes sense if you think it through. Strong personality types receive less feedback. Feedback helps us grow.
