In performance evaluations, which bias occurs when one favorable trait influences the overall perception of an employee?

• A. Halo effect
• B. Group consensus
• C. Hidden costs
• D. Head hunting

Answer: (A)

The halo effect is at play when one favorable trait colors the overall view of an employee’s performance. If a manager notices something positive—like punctuality, friendliness, or confidence—it can lead them to rate other areas, such as productivity or teamwork, more highly than the evidence supports. This creates an inflated overall evaluation and can skew decisions about raises, promotions, or development needs. For example, consistently on-time behavior might make an evaluator perceive work quality or initiative as better than it actually is. To counter this, use structured, behavior-based evaluation criteria with clear indicators, train raters to recognize bias, gather input from multiple sources, and rely on objective data alongside rating scales. The other concepts don’t describe this specific bias: group consensus involves collective agreement rather than a bias from a single trait; hidden costs refer to unrecognized expenses; head hunting is a recruitment tactic.
