We hear constantly that "Diversity is our strength".But "Diversity",without more,is not a "Strength"at all.If i were asked to put together a team to solve a complex problem,and i chose a 6-year old child,a heroin addict,a comatose patient,and a homeless person suffering from severe mental illness,that group would certainly be diverse.But it would not be "strong"-if by that we mean able to solve the problem.Nor would the group be any "stronger" if it consisted of men and women or people of different racial and ethnic backgrounds.We must go back to best and brightest.
