The critical incident method is extremely useful for giving employees job-related feedback. It also reduces the recency bias if raters record incidents throughout the rating period. Of course, the main drawback is that supervisors often do not record incidents as they occur. Many start out recording incidents faithfully but then lose interest. Then, just before the evaluation period ends, they add new entries. When this happens, the recency bias is exaggerated and employees may feel that their supervisors are building a case to support their subjective opinions. Even when the form is filled out over the entire rating period, employees may feel that the supervisor is unwilling to forget negative in cidents that occurred months earlier
