Not a strength. It certainly took the social scientists long enough to demonstrate the obvious:
A bleak picture of the corrosive effects of ethnic diversity has been revealed in research by Harvard University’s Robert Putnam, one of the world’s most influential political scientists.
His research shows that the more diverse a community is, the less likely its inhabitants are to trust anyone – from their next-door neighbour to the mayor….
The core message of the research was that, “in the presence of diversity, we hunker down”, he said. “We act like turtles. The effect of diversity is worse than had been imagined. And it’s not just that we don’t trust people who are not like us. In diverse communities, we don’t trust people who do look like us.”
Diversity is a nightmare. It doesn’t work, and moreover, it never has worked or ethnic nations wouldn’t have developed and been the dominant form of voluntary mass human organization for millenia.
It’s long past time to put the lie to rest.
