The article “How Diversity Makes US Smarter” was a real eye opener. Having never studied diversity per se, it was great to read through many of the previous case studies and experiments.
When people are brought together to solve problems in groups, they bring different information, which is why it’s important that the groups aren’t homogenous, otherwise they would only be rehashing ideas from common comfort zones. I don’t question that comfort is part of why homogenous groups exist, because humans tend to flock with those we identify with most.
The case study regarding democrats and republicans was fascinating. When told they would have to prepare an argument for a) someone from the same political affiliation, or b) someone from the opposing political affiliation; the results were similar in that those preparing for scenario b worked much harder at the defense! Having to prepare something for a diverse group, rather someone not like ourselves, compels us to think of creative ways to get the message across.
