84. Which of the following is an example of the halo effect?
Answer: C
A supervisor's rating of punctuality influences her ratings on other dimensions on the rating form.
The halo effect occurs when an individual's perception of one positive trait influences the perception of other traits. In this case, a supervisor's evaluation of an employee's punctuality positively affects her ratings in other areas, demonstrating the halo effect's impact on judgment.
A) A supervisor's ratings are compressed into a normal distribution.
This option describes a statistical distribution of ratings rather than illustrating the halo effect. It does not involve the influence of one characteristic on the evaluation of others, which is central to the concept of the halo effect.
B) A supervisor's ratings are based on critical behaviors of productivity.
While this option refers to productivity, it does not imply that one trait is affecting the perception of others. The focus on critical behaviors suggests a more objective assessment rather than a subjective influence typical of the halo effect.
C) A supervisor's rating of punctuality influences her ratings on other dimensions on the rating form.
This is a clear example of the halo effect, where the supervisor's positive perception of punctuality leads to higher ratings in unrelated areas, demonstrating how one trait can overshadow others in performance evaluations.
D) A supervisor tends to give all 4's and 5's on a 5-point scale.
This option indicates a leniency bias rather than a halo effect. It does not showcase the influence of one specific trait on the evaluation of additional attributes but rather a general trend in rating behavior.
E) A supervisor has difficulty choosing between two descriptions of a worker's behavior.
This option reflects a decision-making challenge but does not demonstrate the halo effect. It does not involve the influence of one characteristic on the perception of another, which is essential to understanding the halo effect.
Conclusion
The correct answer, C, clearly exemplifies the halo effect by showing how a positive assessment in one area, such as punctuality, can skew evaluations in other areas. All other options fail to illustrate this phenomenon, either by describing unrelated statistical behaviors or by focusing on different biases in rating practices. Understanding the halo effect is crucial in performance evaluations, as it can significantly impact the accuracy of assessments.
