Which bias describes how an interviewer may let one strong positive impression influence ratings in other areas?

• A. Halo Effect
• B. Contrast Bias
• C. Anchoring
• D. Confirmation Bias

Answer: (D)

The idea is that a single strong positive impression can color judgments about other traits. In interviews, if a candidate is particularly polished or likable, the interviewer may unconsciously rate them as more competent, reliable, or a better fit overall, even if the evidence for those other traits isn’t as strong. This ripple effect describes the Halo Effect.

Contrast bias would involve comparing someone to others, not allowing one trait to tilt judgments of all others. Anchoring is sticking too closely to the first information encountered. Confirmation bias is seeking information that confirms preconceptions. The Halo Effect best captures how one favorable impression influences ratings across multiple areas.
