Nature and Consequences of Halo Error: A Critical Analysis
Research-assisted source review
- What it supports
- Major elements of the conventional error account were problematic; common indices confounded real and illusory covariance, leading the authors to recommend a moratorium on using them as dependent error measures.
- Where it may not transfer
- The review focuses on performance appraisal and does not imply global impressions never distort judgement. Independent criteria and experimental comparisons remain necessary in each domain.
