But a peculiar attribute of homogeneous groups is that they can be unusually blind to what they don't know. Conversely, if you read Scott Page's book The Difference, you'll see loads of evidence that while more diverse groups sometimes have more conflict and problems, they're actually better at solving problems and working productively. Samuel Sommers has shown that racially diverse groups faced with decision-making tasks pay more attention and demonstrate better recall of relevant facts. Companies whose boards of directors contain more women show better performance in the stock market. And on it goes.
