Rules are necessarily biased; bias is in the nature of a rule. The rules of baseball are tilted in favor of skill, because skillful competition is what baseball is about; the rules of education, in favor of knowledge, because the extension of knowledge is what education is about.  Rules can and should be fair.  But the notion that fairness means neutrality is a fallacy.

But surely laws should be unbiased, shouldn’t they?  Certainly not.  Laws should be biased toward the common good, the first element of which is justice.  Lady Justice is blindfolded not because she has no criterion, but because she is blind toward all other criteria.  She uses her scales, not her eyes.
