Too much diversity = bad outcomes?

Washington Post today has an interesting article on the economic effect of genetic diversity, concluding that either too much or too little results in very bad outcomes. One wonders if these conclusions translate to the college context, where “too much” diversity erodes the value of the community and its intellectual capabilities:

Ashraf and Galor put this together and argued that this is “reflecting the trade-off between the beneficial and the detrimental effects of diversity on productivity.” Their argument was that a little bit of genetic diversity is a good thing because “a wider spectrum of traits is more likely to be complementary to the development and successful implementation of advanced technological paradigms,” but if a country is too genetically diverse, its economy will suffer from “reduced cooperation and efficiency.” Thus, they wrote, “the high degree of diversity among African populations and the low degree of diversity among Native American populations have been a detrimental force in the development of those regions.”
