Subjectivity in performance assessments can signal a supervisor's bias when rating employees because it reflects personal opinions, feelings, or interpretations rather than objective measurements of performance. When a supervisor relies heavily on their own subjective views, it can lead to inconsistent evaluations that favor certain individuals or groups based on personal preferences rather than actual performance. This bias undermines fairness and can distort the true picture of an employee's abilities and contributions, resulting in an unreliable assessment process.

In contrast, using consistent ratings and standardized evaluation criteria promotes objectivity and fairness. Additionally, gathering feedback from multiple sources can help mitigate individual biases by providing a more comprehensive view of an employee's performance. This overall approach enhances the validity of performance evaluations, making them a more reliable tool for assessing employee effectiveness.
