Final answer:
When a rater relies on her global evaluation of a subordinate, she is more likely to make a Halo effect error.
Step-by-step explanation:
When a rater relies on her global evaluation of a subordinate, she is more likely to make a Halo effect error. The Halo effect occurs when one characteristic of a person or thing is used to make an overall judgment or evaluation of that person or thing. In this case, the rater's overall positive or negative impression of the subordinate may influence how they evaluate specific traits or abilities, leading to a biased assessment. For example, if the rater has a positive overall impression of the subordinate, they may rate each individual trait or ability higher than they deserve based on their overall perception.
