Self–observer rating discrepancies: Once an overrater, always an overrater?

Abstract Differences between the perceptions of self‐raters and other observers are often found on 360‐degree feedback instruments. This article reports on the nature of these self–observer differences. Specifically, self–observer discrepancies were found to be stable over time. In addition, discrepancies on skill‐based multirater instruments were related to discrepancies on personality‐based multirater instruments. This suggests that accuracy in self‐perception is a stable individual difference. The implications for job performance and personality assessment are discussed. © 1993 by John Wiley & Sons, Inc.
