Identifying Criminals’ Risk Preferences, Murat C. Mungan, Jonathan Klick

Faculty Scholarship

There is a 250-year-old presumption in the criminology and law enforcement literature that people are deterred more by increases in the certainty rather than increases in the severity of legal sanctions. We call this presumption the Certainty Aversion Presumption (CAP). Simple criminal decision-making models suggest that criminals must be risk seeking if they behave consistently with CAP. This implication leads to disturbing interpretations, such as criminals being categorically different from law-abiding people, who often display risk-averse behavior while making financial decisions. Moreover, policy discussions that incorrectly rely on criminals’ risk attitudes implied by CAP are ill informed, and may therefore …

Charging The Poor: Criminal Justice Debt & Modern-Day Debtors' Prisons, Neil L. Sobol

Faculty Scholarship

Debtors’ prisons should no longer exist. While imprisonment for debt was common in colonial times in the United States, subsequent constitutional provisions, legislation, and court rulings all called for the abolition of incarcerating individuals to collect debt. Despite these prohibitions, individuals who are unable to pay debts are now regularly incarcerated, and the vast majority of them are indigent. In 2015, at least ten lawsuits were filed against municipalities for incarcerating individuals in modern-day debtors’ prisons. Criminal justice debt is the primary source for this imprisonment.

Criminal justice debt includes fines, restitution charges, court costs, and fees. Monetary charges exist …

Neuroscience And Behavioral Genetics In Us Criminal Law: An Empirical Analysis, Nita A. Farahany

Faculty Scholarship

The goal of this study was to examine the growing use of neurological and behavioral genetic evidence by criminal defendants in US criminal law. Judicial opinions issued between 2005–12 that discussed the use of neuroscience or behavioral genetics by criminal defendants were identified, coded and analysed. Yet, criminal defendants are increasingly introducing such evidence to challenge defendants’ competency, the effectiveness of defense counsel at trial, and to mitigate punishment.

How Bayesian Are Judges?, Jack Knight, Mitu Gulati, David F. Levi

Faculty Scholarship

Richard Posner famously modeled judges as Bayesians in his book, How Judges Think? A key element of being Bayesian is that one constantly updates with new information. This model of the judge who is constantly learning and updating, particularly about local conditions, also is one of the reasons why the factual determinations of trial judges are given deference on appeal. But do judges in fact act like Bayesian updaters? Judicial evaluations of search warrant requests for probable cause provides an ideal setting to examine this question because the judges in this context have access to information on how well they …

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …
