How diversity actually makes us smarter; Washington Post, 7/6/14

Gregory Rodriguez, Washington Post; How diversity actually makes us smarter:

"Successful navigation of this country’s diversity has always required extra thought, and more brainpower. The more diverse the location, the more brainpower required by the people who live there.

In more homogenous parishes, towns, states and countries, residents aren’t necessarily obliged to take that extra intellectual step. In places where the overwhelming majority of residents share a common background, they are more likely to maintain an unspoken consensus about the meaning of institutions and practices. That consensus, Dutch philosopher Bart van Leeuwen reminds us, is enforced “through sayings and jokes, in ways of speaking and moving, and in subtle facial expressions that betray surprise or recognition.” In other words, the way things are is so self-evident that they don’t require a second thought.

Diversity, however, requires second thoughts. When the consensus is challenged in a homogenous place by the presence of new people, things get interesting. The familiar signs and symbols that undergird our implicit understanding of the world can change in meaning. The presence of conflicting worldviews causes confusion, uncertainty, and alienation for holdovers and newcomers alike. These feelings can either cause people to draw back into themselves — or force them to articulate and justify themselves to those who don’t share their view of the world. Or both...

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."
