Contextualizing sentencing disparities: Using conjunctive analysis of case configurations to identify patterns of variability

Abstract

Using national data from felony cases processed in state courts (n = 48,006), the current study investigates the nature and magnitude of contextual variability associated with sentencing outcomes. Multivariate models are first estimated to identify the main effects of various offender and offense variables on sentencing decisions. Conjunctive analysis is then used to evaluate the contextual variability of each of these main effects across all observed combinations of offender and offense attributes. Separate analyses are also conducted among states with and without mandatory sentencing guidelines to explore whether these guide- lines reduce this variability across different contexts. Findings from this study and its comparative methods are discussed in terms of implications for future research on criminal sentencing and assessing the contextual variability of the main effects of particular legal and extralegal factors.
