Not exactly a comment on the article, rather my own findings on the same subject: - There is research that shows that the most successful teams are those with the greatest intellectual diversity, assuming there is an unhindered exchange of information between team members. If team members feel inhibited from sharing ideas, or critiquing the ideas of others, diversity doesn't improve outcomes. - There is also evidence that challenging problems in a field are more likely to be solved by people from outside the field. This seems to be driven by the fact that each field has particular problem solving techniques, and problems that are difficult to solve using a given set of techniques may yield more readily to techniques from other fields.
