The perceptual error that is likely impacting Mi's performance result is the Halo Effect. The Halo Effect occurs when a person's overall impression of an individual influences how they perceive and interpret the individual's behavior. In this case, Mi's strong interpersonal skills have created a positive impression, and this impression is influencing how her manager perceives her overall performance. As a result, her manager is likely giving her higher ratings than she would receive if her performance was evaluated objectively. This is because the manager's positive impression of Mi is influencing how they perceive her performance in other areas. This perceptual error is impacting her performance result because it is not providing an accurate assessment of her performance, which could lead to Mi not receiving the feedback she needs to improve in areas where she is struggling.
