Group intelligence, the researchers discovered, is not strongly tied to either the average intelligence of the members or the team’s smartest member. And this collective intelligence was more than just an arbitrary score: When the group grappled with a complex task, the researchers found it was an excellent predictor of how well the team performed.
…Other tenets of group success also seemed to fall by the wayside: A group’s motivation, satisfaction, and unity were unimportant. Instead, the researchers found that when a group had a high level of collective intelligence, the members tended to score well on a test that measured how good they were at reading other people’s emotions. They also found that groups with overbearing leaders who were reluctant to cede the floor and let the others talk did worse than those in which participation was better distributed and people took turns speaking.
