I would use more general qualifiers in place of those specific expressions of the problem: "When comparing two candidates of otherwise approximately equal qualification, apply historical socio-economic advantages/disadvantages as modifiers to get their probable scores in the absence of those modifiers, then re-evaluate accordingly." Compare it to testing two sets of children, one that was kept up all night and one that got to sleep after studying, and extrapolate writ-large. In a similar vein, we can't make useful assessments about alcoholism susceptibility in Native American populations without first accounting for all of the historical socio-economic pressures that would likely drive a disproportionate amount of any given population to drink.
