Argument: Diversity improves group decision-making
Stephen Cranston. "The argument for diversity." Financial Mail. December 4, 2009: "in the US, experiments by Scott Page of the University of Michigan found that a diverse group was better at solving complex problems than experts. The reason is that people with similar qualifications or professional training often think alike. Adding people with different skills, backgrounds and life experiences tended to improve the group's performance. And there is no doubt that the monocultural management at Anglo and Barlows was no longer appropriate in the 1990s and beyond."
