Which approach can managers utilize to counteract the Halo Effect?

Considering the Halo Effect, which involves allowing a positive impression in one area to influence evaluations in other areas, the most effective approach for managers is to consider the overall employee performance history. By analyzing an employee's performance across various criteria over time, managers can create a more comprehensive and balanced view of their capabilities. This approach mitigates the risk of a single positive or negative trait skewing the overall assessment, leading to fairer evaluations.

Reliance solely on subjective evaluations can reinforce biases rather than provide a clear picture of performance. Consulting a wider array of opinions can be useful but does not address the core problem of bias if the evaluation framework remains subjective. Setting ambiguous targets would likely add confusion and inconsistencies, further complicating fair assessments rather than clarifying performance expectations. Analyzing performance history offers a structured method to assess contributions objectively and minimize the Halo Effect's impact.
