Please summarize the following text A first limitation that is inherent in comparing AC ratings and inventory-based self/other-ratings
The present findings offer new insights into why other-ratings are often more predictive of job performance than self-ratings.
Other findings from our study point towards constraints when using ACs as behavior-focused personality measures.
