Budget allocation formulas claim objectivity, and hence fairness. But factors composing the formula are limited to supply, demand, and cost. Attempts to correct for this imbalance of empirical data like usage have led to the use of weighted values in the formulas. This paper seeks to argue that assigning “weight” in a formula introduces value judgments and subjectivity, leaving only the misplaced illusion of objectivity.
