That's OK, I'm a quick study. I don't usually hunt through pages looking for specific posts many pages away if the poster cannot be bothered to link me directly to it themselves, but in your case, I made an exception. The SA article sums it up well by saying:
"Being around people who are different from us makes us more creative, more diligent and harder-working." I scanned the rest of the article but they really need not say any more. I get that. I wrote a textbook on applied psychology, and I get that, but I might question how they derived some of their conclusions as existing in conditions not easily replicated in the real word, or as generally defined by others. In theory, that is all fine and good, but the question really is how often the PRACTICE of utilizing it in business and education, usually driven by force of law to meet government mandates actually SUCCEEDS in REALIZING that ideal for the reasons it originate as? I guess that would be the basis of yet another study.
Well, I've seen many a good, reasonable, intelligent, thoughtful, educated, considerate, patient and highly regarded people go as guest speakers to various campuses where, when I was in school, they championed differences of opinion, to merely expatiate the traditional, conservative edict, not in anyway extreme or racist, in fact, what has been the de facto standard POV of America and Americans for more than 200 years that gave us the best country in the world that millions flock to as champions of liberty and rights, but instead now get chased out of there lucky to get out alive by wild, fervent, radicals screaming and threatening and doing violence.
I seriously doubt these screaming morons will preserve and maintain the America that once brought the world to love and respect us as the goto people for justice and human rights that those heinous extremists gave all of us.
