Despite an upsurge of red tape research, a central issue remains unresolved. The most widely used red tape measures draw on key informant reports about red tape. The starkest objection to such measures is that key informant reports are mere perceptions—perceptions that are subject to distortion. We assess the validity of key informant perception-based measures of personnel red tape by using "anchoring vignettes." Findings suggest that anchoring vignettes can be used to improve the accuracy of survey measures of red tape. Implications of findings for red tape scholarship and survey measurement in public management are discussed.
