What is the definition of the halo effect?
Explanation
The halo effect is a cognitive bias where an observer's overall positive impression of a person influences their judgment of that person's specific traits or performance. In a workplace context, if an employee is perceived as likable or charismatic, an evaluator may unconsciously assume they are also highly competent, leading to an inflated performance rating regardless of actual metrics. This phenomenon demonstrates how a single positive attribute creates a "halo" that distorts the assessment of other unrelated characteristics. Consequently, the correct definition describes a positive initial impression causing bias in subsequent performance evaluations. This mechanism highlights the importance of structured evaluations to prevent such perceptual distortions.
