What common rating error causes a rater to judge based on an overall impression rather than specific traits?

• A. Halo effect
• B. Bias effect
• C. Contrast effect
• D. Attribution error

Answer: (A)

The halo effect is a cognitive bias that occurs when a rater allows their overall impression of a person or situation to influence their evaluations of specific traits. Instead of objectively assessing each attribute—such as work ethic, communication skills, or technical ability—the rater may be swayed by a positive or negative overall perception. For instance, if a supervisor views an employee as particularly likable, they may rate that employee’s performance more favorably across the board, even in areas where the employee may not excel. This can lead to skewed evaluations that do not accurately reflect the individual’s skills or contributions.

The halo effect highlights the importance of being mindful of how general impressions can unintentionally distort more nuanced assessments. By understanding this phenomenon, counselors and evaluators can strive for more accurate and fair evaluations and decisions.
