Step-by-step explanation:
Experts say that when studying the quality of their own behavior, individuals may exhibit biases or inaccuracies in their self-assessment. For example, research has shown that individuals tend to underrate their own performance, while supervisors also tend to underrate employees who give themselves modest feedback ratings. Additionally, there is a well-known phenomenon called the Dunning-Kruger effect, where incompetent individuals overestimate their own abilities while highly competent individuals underestimate their abilities. Therefore, it is important to consider external perspectives and feedback when evaluating one's own behavior.
