What makes effective teams? The researchers eventually concluded that what distinguished the ‘‘good’’ teams from the dysfunctional groups was how teammates treated one another. The right norms, in other words, could raise a group’s collective intelligence, whereas the wrong norms could hobble a team, even if, individually, all the members were exceptionally bright.

Second, the good teams all had high ‘‘average social sensitivity’’ — a fancy way of saying they were skilled at intuiting how others felt based on their tone of voice, their expressions and other nonverbal cues.

Important to note is that in order for groups to be high functioning they most have psychological safety. Harvard Business School professor Amy Edmondson defines as a "shared belief held by members of a team that the team is safe for interpersonal risk-taking." Psychological safety is "a sense of confidence that the team will not embarrass, reject or punish someone for speaking up".
