The downside of diversity
THE closest thing the business world has to a universally acknowledged truth is that diversity is a good thing: the more companies hire people from different backgrounds the more competitive they will become. Diversity helps companies to overcome talent shortages by enlarging their talent pools. It helps them to cope with globalisation by expanding their cultural horizon. It stimulates innovation by bringing together different sorts of people. And so on.
But what about the downside of diversity? It does not pay to ask this question. Many countries have equal-opportunity laws on their books. American universities (and many others as well) are institutionally committed to the idea that diversity promotes learning and creativity. Most important perhaps, nobody wants to come across as unsympathetic to minorities or unappreciative of cultural variety.
Yet a glance beyond the corporate-diversity statements suggests a more complicated picture. It is notable how many of the world’s best companies, such as McKinsey and Apple, have cult-like cultures—probably because they are also very diverse: they need a strong culture. It is also notable how many of the world’s best companies are rooted in small towns: think of Lego (Billund) or Walmart (Bentonville). Distinctive religious groups such as the Mormons in America and the Parsis in India have also made an outsized contribution to corporate life. . . .
