The issue of bias in risk assessment instruments used in the criminal justice system is a critical one that has far-reaching implications for criminal justice reform. A recent study on the federal risk assessment instrument, known as PATTERN, has raised concerns about the overprediction of recidivism risk for some racial and ethnic groups, particularly Black, Hispanic, and Asian individuals. This bias has been documented in previous versions of PATTERN and continues to be a significant issue.
The federal risk assessment instrument is a key component of the First Step Act, which aims to improve criminal justice outcomes and reduce the federal prison population while ensuring public safety. The study evaluates PATTERN’s predictive accuracy, dynamic validity, and racial/ethnic neutrality using rearrests and incarcerations as measures of recidivism.
While PATTERN has been shown to be a strong predictor of general and violent recidivism, the study reveals that it overpredicts the risk of recidivism for certain racial and ethnic groups compared to white individuals. This differential impact raises concerns about the fairness and neutrality of the instrument, as it may lead to disparities in risk categorization and recidivism predictions.
The study also highlights the challenges in achieving racial and ethnic fairness in risk assessment instruments, as different definitions of fairness can be conflicting and complex. While efforts are being made to address the bias in PATTERN, there are no simple solutions to this complex problem. Deliberate study and engagement with stakeholders and experts are needed to identify an optimal path forward.
Moving forward, researchers and experts are exploring potential solutions to reduce disparities in recidivism predictions across racial and ethnic groups. The study cohort included individuals released through September 30, 2019, and future reviews will cover additional cohorts to assess the impact of the COVID-19 pandemic and civil unrest on recidivism outcomes.
In conclusion, the issue of bias in risk assessment instruments is a significant challenge for criminal justice reform. Addressing this bias is crucial to ensuring fairness and equity in the criminal justice system. Stakeholders must continue to work together to identify solutions that promote racial and ethnic neutrality in risk assessment instruments and support the goals of the First Step Act.
