Bias-PerformanceAppraisals

Connection: Bias ↔ Performance Appraisals & Recruitment

PHIL252 establishes that bias is a systematic distortion in reasoning — a preference that causes us to evaluate evidence unfairly. ADMN201 Ch8 states directly that job interviews are poor predictors of success precisely because of bias, and advocates behaviour-based interviewing as the structural remedy. The same bias-correction logic PHIL252 teaches applies directly to the design of fair HRM practices.

From PHIL 252

Bias identifies preferences and attitudes that systematically distort reasoning. Several types are directly relevant to hiring and appraisals:

  • Confirmation bias: Interviewers form a first impression and then seek evidence that confirms it — discounting contradictory signals
  • In-group bias: Interviewers unconsciously favour candidates who remind them of themselves (shared background, style, appearance)
  • Halo/horn effect: One strong or weak trait colours the evaluation of all other traits
  • SelectionBiasVariants: Who reaches the interview stage is already a non-representative sample — only candidates who passed the résumé filter are visible, meaning the full applicant population is never observed

PHIL252’s core remedy for bias is the same as ADMN201’s: demand concrete, observable evidence rather than accepting impressions or vague claims.

From ADMN 201

RecruitmentAndSelection and HumanResourceManagement both note:

  • Unstructured interviews are one of the weakest predictors of job success precisely because they give bias maximum room to operate
  • Behaviour-Based Interviewing reduces this by anchoring the interviewer on past, observable behaviour (“Tell me about a time you handled X…”) rather than hypothetical scenarios — functionally identical to PHIL252’s instruction to demand specific evidence, not speculation
  • The ABC Feedback Model in performance appraisals is a structured protocol fighting the same biases:
    • Accurate: use objective examples from a performance log; avoid “always/never” (combats confirmation bias and halo effect)
    • Business-Oriented: focus on business reasons, not personality (combats in-group bias and personal animus)
    • Consistent: give feedback throughout the year (combats recency bias — the tendency to weight recent events disproportionately)

Why This Matters

Knowing PHIL252’s bias taxonomy turns ADMN201’s HR recommendations from procedural checklists into principled systems:

  • You can name the specific bias each interview structure addresses
  • You can explain why behaviour-based interviewing works as a countermeasure (it reduces reliance on impression and increases reliance on evidence)
  • You can critique performance appraisal systems that violate the “Accurate” and “Consistent” principles by naming the bias those violations enable
