"The belief that one will not be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes, and that the team is safe for interpersonal risk taking"
My experience also. It's sort of a pattern with other behavioral attributes too.
Of course correlation is not causation, places that don't talk about it also might not have it nor care. But talking about it is sort of trying to convince the org, and you only need to spend time convincing people of something that isn't the case.
