Final answer:
The advantage of Behavioral Methods in reviews is their potential fairness for reward and promotion decisions and the beneficial discussions they can stimulate for learning.
Step-by-step explanation:
One advantage of Behavioral Methods of review, including 360-degree feedback, is that they have the potential to be fair for reward and promotion decisions. While studies have shown that self and peer ratings can be unreliable and supervisors might underrate employees who provide modest feedback about themselves, there is an upside to this method. The variability in ratings can stimulate valuable discussions between employees and supervisors, leading to increased learning opportunities as they explore the reasons behind different perceptions of performance.
