This is an instructive story to keep in mind whenever we are told that companies should look especially hard to find employees that will move the company toward greater "diversity." In the first place, if companies are looking especially hard for people of one color, then they are going to overlook and show less interest in people of another color. That is the point, right? Second, if your company has told you, a manager, that it wants to find qualified people of a particular color, then you inevitably are going to put your thumb on the scale whenever a candidate of the "right" color appears. Don't want to disappoint the boss, you know.

Either way, you will not be hiring the best people. Sometimes the best person will also happen to be the "wrong" color, and so he won't get hired. Other times, the person of the "right" color will seem to be suitable, but only because you are looking so hard to find someone of that color.
