I’ve written a bit before about diversity and how it fits into getting better results and how it is a key part of collaboration success. I’ve recently finished the book Future Perfect: The Case For Progress In A Networked Age by Steven Johnson. As mentioned before, I’m a huge fan of his material which I’ve referenced here and here. He writes:
When groups are exposed to a more diverse range of perspectives, when their values are forced to confront different viewpoints, they are likely to approach the world in a more nuanced way, and avoid falling prey to crude extremism.
and a key thought:
Diversity does not just expand the common ground of consensus. It also increases the larger group’s ability to solve problems. The pioneer in this line of research is the University of Michigan professor Scott E. Page. He has spent the past twenty years building a convincing case for what he calls the “Diversity trumps ability” theory, demonstrating the phenomenon in sociological studies and mathematical models. Take two groups of individuals and assign to each one some kind of problem to solve. One group has a higher average IQ than the other, and is more homogeneous in its composition. One group, say, is all doctors with IQs above 130; the second group doesn’t perform as well on the IQ tests, but includes a wide range of professions. What Page found, paradoxically, was that the diverse group was ultimately smarter than the smart group. The individuals in the high-IQ group might have scored better individually on intelligence tests, but when it came to solving problems as a group, diversity matters more than individual brainpower.
We want diversity for another reason as well: because we are smarter as a society—more innovative and flexible in our thinking—when diverse perspectives collaborate.
