What Is The Leniency Bias?
The leniency bias describes the situation where the manager tends to be more lenient than his or her peers, when rating employees, OR, is more lenient with one employee as compared to another.
Clearly, this results in inflated ratings, and certainly inaccurate ones, since areas for performance improvement tend to be ignored or swept under the rug in performance appraisals.
The leniency bias doesn't occur only with employee ratings. It can occur with any system if and when the manager has a tendency to be overly positive about performance.
