Michael is a friendly good looking person who is liked by almost everyone who meets him. Michael's supervisor considers him a good employee, although his job performance is actually poor in many ways

The supervisor's inaccurate evaluation of Michael is likely due to
A) the halo effect.
B) trait affectivity.
C) the contrast effect.
D) stereotype threat.

Answer: A
Rationale: The Halo effect occurs when a rater thinks highly about one aspect of an employee's job or personality and this leads him or her to provide similar ratings for other aspects of the employee's work. In this example, the fact that the supervisor thinks highly of Michael's personality leads him to rate Michael's work performance higher than it should be.
