Criminal history's expiration date: Evidence of prediction decay (Forthcoming)
Abstract
Criminal history is a well-established predictor of future offending, yet recidivism risk declines with time. Research has struggled to reconcile this tension as criminal history is often treated as a static indicator of risk, while desistance is commonly inferred rather than directly modeled. Using a five-state population of criminal charges spanning forty years (N = 16,594,838; person-year observations = 746,396,524), we model recidivism prediction decay following a prior charge. We develop an event-level framework that estimates the year-by-year decline in predictive value associated with prior criminal events, providing the first population-scale estimates of criminal history decay. Results indicate that recidivism risk follows a pattern consistent with exponential decay, with each additional year producing a proportional reduction in offending odds. After accounting for individual heterogeneity, the same exponential pattern is evident across geographic locations, demographic groups, offense types, incarceration exposure, and historical period. Finally, although baseline probabilities differ, recidivism risk converges with the population base rate within nine to ten years. These findings provide a dynamic framework for assessing criminal history and challenge reliance on static indicators that may overstate reoffending risk.

My research focuses on advancing evidence-based practices in criminal justice. Primary areas of research include evaluating and constructing risk-need assessments to enhance decision-making processes, addressing challenges related to prison and jail crowding, and exploring correctional system reforms.
