A team of researchers worked on factors improving collective intelligence and have found out a surprising factor: the more women in a group, the smarter it gets. Contrarily to all expectations, high individual IQ scores or highly motivated and "happy" groups did not perform better. The ones with more women did, however. And this only stopped at the extreme end, that is, when no more males were in the team, then only did the performance start to decrease. A real revolution, since all groups can benefit from this : family, team activities, business, politics. Maybe worth considering adding a few women colleagues in that Board in September?
