Very interesting study! http://hbr.org/2011/06/defend-your-research-what-makes-a-team-smarter-more-women/ar/1#.TlAFtC1WF-A.facebook

The finding: There’s little correlation between a group’s collective intelligence and the IQs of its individual members. But if a group includes more women, its collective intelligence rises.

The more women in a group, the higher the group scored on their tasks –brainstorming, decision making, and visual puzzles, and solving one complex problem.

Another great quote from the article:

What do you hear about great groups? Not that the members are all really smart but that they listen to each other. They share criticism constructively. They have open minds. They’re not autocratic. And in our study we saw pretty clearly that groups that had smart people dominating the conversation were not very intelligent groups.

That last bit reminds me of 1 Corinthians 12. “But God has put the body together, giving greater honor to the parts that lacked it, so that there should be no division in the body, but that its parts should have equal concern for each other.”
