Subjective standards are difficult for courts to evaluate and difficult for plaintiffs to rebut, and their use in employment decisions should be viewed with suspicion.  See Hill v. Seaboard Coast Line R. Co., 885 F.2d 804, 808-09 (11th Cir. 1989); see also Watson v. Fort Worth Bank & Trust, 487 U.S. 977, 1009 (1988) (Blackmun J., concurring) ( “Allowing an employer to escape liability simply by articulating vague, inoffensive-sounding subjective criteria would disserve Title VII's goal of eradicating discrimination in employment.”); Miles v. M.N.C. Corp., 750 F.2d 867, 871 (11th Cir. 1985) (“subjective evaluations . . . provide a ready mechanism for … discrimination.”).
