Which of the following is an example of the halo effect?

Rationale

A supervisor's rating of punctuality influences her ratings on other dimensions on the rating form.

The halo effect occurs when one positive or negative trait of an individual influences the overall evaluation of their other traits. In this case, the supervisor's perception of an employee's punctuality positively affects her ratings on different aspects of their performance, demonstrating how a single characteristic can disproportionately impact overall judgment.

A (A supervisor's ratings are compressed into a normal distribution.) YOUR ANSWER

This choice refers to the statistical distribution of ratings rather than an evaluative bias. Normal distribution indicates that ratings are spread out in a predictable pattern, but it does not illustrate how one specific rating affects others. The halo effect is about individual traits influencing overall assessments, not the statistical formatting of ratings.

B (A supervisor's ratings are based on critical behaviors of productivity.) YOUR ANSWER

This option suggests that ratings are grounded in specific, relevant behaviors, which is a fair and objective evaluation practice. However, it does not represent the halo effect since it implies ratings are made independently based on distinct behaviors rather than being influenced by an overarching impression of the employee.

D (A supervisor tends to give all 4's and 5's on a 5-point scale.) YOUR ANSWER

While this may indicate leniency bias or a lack of differentiation in ratings, it does not directly illustrate the halo effect. The halo effect pertains to how one specific trait affects the evaluation of other traits, rather than a general tendency to rate highly across the board without regard to individual performance facets.

Conclusion

The halo effect exemplifies how a singular attribute, such as punctuality, can skew the overall assessment of an individual's performance across multiple dimensions. In this scenario, the supervisor's favorable perception of punctuality serves as a cognitive bias that enhances ratings in unrelated areas, highlighting the importance of understanding evaluative biases in performance reviews.
