Diversity is good, goes the conventional wisdom of the business world: companies that look and think more like the spectrum of their customers serve their clientele better. With a greater number of perspectives brought to a problem, diversity opens up new opportunities for synergistic information sharing, lifting a team's creativity and work quality, proponents say. Successes such as inventing cosmetics for women with various skin tones, employing Spanish-speaking sales representatives, and marketing vacations to locations of historical importance to African-Americans readily come to mind.
