It is not just about one gender. It is about lots of diversity. People from different backgrounds come at issues from different perspectives. Whether it is women, class, nationality, ethnicity etc people will (on average) have different perspectives.Agree with this completely……the worst team environments I experienced in corporate life (particularly at Executive level) were always those that were dominated by one gender - didn’t matter whether it was male or female, they could be equally bad.
Group think is a curse. Imagine if a government surrounded themselves with people who think just them and don’t allow differing views of they got expelled from the cabinet. Hang on a second.
