An issue that came up quite frequently in my latest reading of Andrew Hacker’s 1992 (updated in 1995) book, Two Nations: Black and White, Separate, Hostile, Unequal
 was that of qualifications.  Under affirmative action policies for jobs
 and admission to universities, the required qualifications are often 
lower for African-American applicants than they are for white 
applicants.  Critics then ask: Isn’t is disastrous to give people jobs 
or educational opportunities for which they may not be qualified?
One track that Hacker takes in responding to criticisms of this 
policy is that perhaps the qualifications themselves are not the best 
measures of whether or not one can bring something useful to a job, or a
 school.  African-Americans can bring diversity, which increases the 
knowledge of the community that they enter.  African-American cops can 
help the police force to interact better with African-American 
communities.  Moreover, Hacker wonders why law schools should hire 
primarily people who have published research or an advanced degree, 
since “practical experience and an ability to communicate may actually 
make for better teaching” (page 130).  Hacker also takes a swipe at the 
SATs, maintaining that they are not a measure of the success that one 
will attain later in life, that they presume knowledge of middle-class 
life, and that they “are biased in favor of people who have a knack for 
solving puzzles at a one-a-minute rate”, even as they discriminate 
against those “drawn to music and the arts” (page 149).
Why, on average, are other minorities, or people from the white lower
 economic classes, able to do better on the SAT than African-Americans? 
 Hacker offers a variety of reasons: Asian students may have studied 
more American history and literature, immigrants have often been trained
 in math and the multiple-choice method in their own countries, etc.  
But Hacker seems to believe that racism is a factor: that, because there
 are many whites who look down on black people and do not want to be 
around them, African-Americans are cut off from the exposure to the 
white world that they need to do well on SAT tests, or other 
standardized tests.  John McWhorter in Losing the Race would probably blame anti-intellectualism and separatism within African-American communities.
Hacker does not appear to go so far as to dismiss thoroughly all of 
the current required qualifications.  For example, on page 132, he 
refers to the argument that it is important for cops to be aware of 
complex legal issues and to be able to write precise reports so that 
what they do will hold up in court.
I think that Hacker makes good points.  I still believe that, say, 
solid knowledge of the sciences is essential for physicians, but I am 
open to considering additional forms of aptitude, as well.
