Writing in City Journal, John Leo examines the findings of Harvard political scientist Robert Putnam, the author of Bowling Alone, on immigration's effect on the social fabric. An excerpt:
Putnam’s study reveals that immigration and diversity not only reduce social capital between ethnic groups, but also within the groups themselves. Trust, even for members of one’s own race, is lower, altruism and community cooperation rarer, friendships fewer. The problem isn’t ethnic conflict or troubled racial relations, but withdrawal and isolation. Putnam writes: “In colloquial language, people living in ethnically diverse settings appear to ‘hunker down’—that is, to pull in like a turtle.”
In the 41 sites Putnam studied in the U.S., he found that the more diverse the neighborhood, the less residents trust neighbors. This proved true in communities large and small, from big cities like Los Angeles, Chicago, Houston, and Boston to tiny Yakima, Washington, rural South Dakota, and the mountains of West Virginia. In diverse San Francisco and Los Angeles, about 30 percent of people say that they trust neighbors a lot. In ethnically homogeneous communities in the Dakotas, the figure is 70 percent to 80 percent.
Diversity does not produce “bad race relations,” Putnam says. Rather, people in diverse communities tend “to withdraw even from close friends, to expect the worst from their community and its leaders, to volunteer less, give less to charity and work on community projects less often, to register to vote less, to agitate for social reform more, but have less faith that they can actually make a difference, and to huddle unhappily in front of the television.” Putnam adds a crushing footnote: his findings “may underestimate the real effect of diversity on social withdrawal.”
