Does diversity make you smarter? [Commentary]

New research shows that diverse settings make people more thoughtful

July 15, 2014|By Gregory Rodriguez

An Irishman, a Jew and a Mexican walk into a bar. It's a classic set-up line for a classic American joke. But it's also a means of coping with our diversity.

We need such jokes. Despite all our slogans to the contrary, diversity such as ours isn't always easy to negotiate. Humor is just one of the ways Americans navigate, narrate, expose and otherwise unburden ourselves of the absurdities and pitfalls of living in such a complicated place.

Eight years ago, Harvard political scientist Robert Putnam released a now-famous study concluding that diversity lowers social trust. Those of us living in ethnically diverse settings, the study found, "tend to withdraw from collective life, to distrust their neighbors, regardless of the color of their skin, to withdraw even from close friends, to expect the worst from their community and its leaders, to volunteer less, give less to charity," and to spend more time sitting in front of the television.

But Mr. Putnam didn't explore the other side of that coin: how millions of us manage to overcome the social distrust that diversity can foster.

I have a very devout Nicaraguan-born friend who lives in the Bay Area. She likes to say that practicing Catholicism would be so much easier had she stayed in the country of her birth. Here in the U.S., she's a member of a diverse congregation made up of Filipinos, Mexicans, Mexican-Americans and a few older Anglos and African-Americans. Recently, the priest asked the congregation to vote on which devotional figure they should install in the church first. Most Nicaraguan Catholics maintain a special devotion to Our Lady of the Immaculate Conception. Mexicans are partial to the Virgin of Guadalupe, while Filipinos venerate the Holy Child of Atocha. My friend was obliged to sift through her feelings about her tradition and others, as well as to consider what she thought was fair and best for the common good. In the end, she voted for the Holy Child of Atocha, mostly because of how impressed she's always been by the dedication of her congregation's Filipinos, who show up even to services that compete with big sporting events.

In more homogeneous places, residents don't have to do this extra thinking. The way things are is so self-evident that they don't require a second thought. Diversity, however, requires second thoughts.

The late historian Timothy L. Smith famously called migration to the U.S. a "theologizing experience" that forced newcomers into the existential dilemma of having to "determine how to act in these new circumstances by reference not simply to a dominant 'host' culture but to a dozen competing subcultures, all of which were in the process of adjustment."

This burden of having to find your place in a landscape both shifting and unfamiliar has forged both the American character and our institutions. Despite that fact, scholars who've studied the cognitive effects of diversity have long made the mistake of treating homogeneity as the norm. Only this year did researchers from MIT, Columbia University and Northwestern University publish a paper questioning the conventional wisdom that homogeneity represents some kind of objective baseline for comparison or "neutral indicator of the ideal response in a group setting."

To bolster their argument, the researchers cite a previous study that found that members of homogeneous groups tasked with solving a mystery tend to be more confident in their problem-solving skills than their performance actually merits. By contrast, the confidence level of individuals in diverse groups corresponds better with how well their group actually performs. The authors concluded that homogeneous groups "were actually further than diverse groups from an objective index of accuracy" and that people in diverse groups "are more likely to step outside their own perspective and less likely to instinctively impute their own knowledge onto others" than people in homogeneous groups.

So it should follow that operating in a diverse environment makes you smarter. Not that that makes it any easier. Diversity doesn't require us simply to learn how to celebrate our differences. It requires us to tax our brains by questioning our worldviews, our beliefs, and our institutions. American ingenuity isn't simply born of the fusion of peoples into your favorite metaphor for mixture. Whether we realize it or not, the good-humored hard work of living with people different from us has always been the source of America's genius.
