360-degree feedback: the use of multiple perspectives for manager feedback --> evaluated by peers, subordinates and supervisors on several dimensions of performance (+ self evaluation).  --> modest agreement.
--> the effect of the biases of individuals can be reduced.
--> it is the best and not the worst performers who seem to benefit --> those individuals who received low ratings from others and rated themselves low as well had the worst reactions to feedback --> if one knows his or her performance is poor, having those beliefs corroborated by others was not helpful.
