A recent research report  suggests that an ethnically diverse group is better at making decisions than a group that are all alike. These results build on other studies that show that diverse groups in general are better at making decisions . Irving Janis, who first identified the concept , argues that ‘homogeneity’ is one of the key prerequisites for Groupthink, which is a bad outcome. So all we have to do to prevent Groupthink is to insist on diversity, especially at the Board level?
Whoa, hold on, it is not as easy as that! It turns out that it doesn’t come down to ‘diversity’ per se but ‘Trust’.
