"The Downside of Diversity"

I'm not going to go into a whole thing about this article in the Boston Globe, reporting on the findings of Harvard political scientist Robert Putnam, who has reportedly "found that virtually all measures of civic health are lower in more diverse settings." Mostly I'm not going to go into it, because I already have (nearly a year ago, when Putnam first teased us with these findings) and because I still haven't read the whole study—although, having read more about it, it appears likely my concerns remain valid. (Echidne also raises a good point about mass media here.)

This is definitely a work with which progressives will want to familiarize themselves (a la The Bell Curve, and for similar reasons).
