Statistically-derived algorithms, adopted by many jurisdictions in an effort to identify the risk of reoffending posed by criminal defendants, have been lambasted as racist, de-humanizing, and antithetical to the foundational tenets of criminal justice. Just Algorithms argues that these attacks are misguided and that, properly regulated, risk assessment tools can be a crucial means of safely and humanely dismantling our massive jail and prison complex. The book explains how risk algorithms work, the types of legal questions they should answer, and the criteria for judging whether they do so in a way that minimizes bias and respects human dignity. It also shows how risk assessment instruments can provide leverage for curtailing draconian prison sentences and the plea-bargaining system that produces them. The ultimate goal of Christopher Slobogin's insightful analysis is to develop the principles that should govern, in both the pretrial and sentencing settings, the criminal justice system's consideration of risk.

‘In Just Algorithms, Christopher Slobogin – one of the most incisive criminal law scholars of his generation-makes plain how scientifically-valid risk assessment could transform the criminal justice system, from the pretrial detention of suspected offenders through the sentencing of convicted offenders. The transparent ‘jurisprudence of risk' articulated here is a blueprint for thorough systemic reform.'

‘At a time of hot debate about the dangers of big data and machine learning, Just Algorithms is a welcome addition to the literature. Slobogin's basic premise is that, if applied judiciously, risk assessment instruments could help achieve meaningful reform in the criminal justice system. Slobogin unpacks and addresses important critiques of risk assessment-including concerns about racial bias-in the comparative context of maintaining the status quo. He also argues for revolutionary changes to the current sentencing regime. The book is beautifully grounded in law and research – but innovative, concise, and refreshingly clear. A must read for anyone with an interest in criminal justice.'

‘In Just Algorithms, Slobogin offers a thoughtful and much-needed discussion of the promise and perils of predictive algorithms in the criminal justice system. The book is a must-read for policymakers, practitioners, and researchers grappling with challenging questions on the role of algorithms in driving lasting reform.'

‘Just Algorithms puts risk assessment instruments at the center of American decarceration policy, arguing that they should be the main guideposts for parole-release decisions to shorten the nation's overlong prison terms. At the same time, Professor Slobogin advocates Olympian legal protections to guard against inaccuracy, unfairness, and racial bias in risk-influenced decisions. His vision would give unprecedented new rights to incarcerated persons – reaching toward a much-needed Due Process revolution in US prison policy.'

‘... one of the first in-depth, systematic legal arguments in favor of automating justice that considers legal and scientific aspects of criminal punishment via the simulation of recidivism. As such, the book is necessary reading for anyone seriously interested in criminal justice reform and the ethical, legal, and social implications of applying data science technologies in judicial contexts.’
