Abstract

Organizational research frequently involves seeking judgmental response data from informants within organizations. This article discusses why using multiple informants improves the quality of response data and thereby the validity of research findings. The authors show that when there are multiple informants who disagree, responses aggregated with confidence- or competence-based weights outperform those with response data-based weights, which in turn provide significant gains in estimation accuracy over simply averaging informant reports. The proposed methods are effective, inexpensive, and easy to use in organizational marketing research.
