Discrimination via statistics

Wish I'd said that!

[Reprinted from Issues & Views September 6, 2004]

The grand fallacy of our times is that various groups would be equally represented in institutions and occupations if it were not for discrimination. This preconception has undermined, if not destroyed, the crucial centuries-old legal principle that the burden of proof is on the accuser.

Wal-Mart is only the latest in a long series of employers who have been hit with charges of discrimination on the basis of statistical differences among members of their workforce -- differences between women and men in this case.

Back during the 1980s a similar charge was brought against Sears, even though no one could find a single woman in all the hundreds of Sears stores who had been discriminated against -- just numbers that were different as between women and men. When you broke down the numbers, it turned out that women were not equally represented among people who sold automotive equipment or construction materials. It also turned out that many women had no interest in selling automotive equipment or construction materials, and had turned down opportunities to do so.

In many other situations, women have avoided jobs that demand such long hours of work, or so much travel, that it would make taking care of their children virtually impossible. The biggest difference in income is between married women and everyone else. Women who never married have long held their own economically.

The most blatant fact about male-female differences is often ignored by those on the hunt for discrimination: Women have babies. That usually means interruptions in careers and different choices of careers beforehand, because some occupations can stand interruptions better than others.

Male-female differences in incomes and occupations rose or fell throughout the 20th century as women's age of marriage and childbearing rose and fell. But such mundane facts carry little weight with lawyers or social crusaders on the hunt for discrimination.

Sheer dogmatic repetition has pounded into our minds the notion that all groups have similar capabilities, when in fact they do not necessarily have even the same interest in developing the same capabilities. Potential may be the same but developed capabilities depend on a lot more, including interest and circumstances. Yet those who start with the preconception of equal capabilities are quick to seize upon numbers showing group differences in results as proof that someone else has done something wrong. That is the grand fallacy of our time.
