Incorporating Social Science Into Criminal Defense Practice, Eve Brensike Primus

Articles

In recent decades, social scientists have created a treasure trove of empirical and sociological data that defenders can and should use to help their clients. Evidence rules, criminal law, and criminal procedure are filled with concepts informed by social science. When is evidence likely to unfairly prejudice a defendant in the eyes of a jury? Do police interact differently with members of minority populations and how should that inform concepts of reasonableness? How easy or difficult is it for people to identify individuals they see during high-stress criminal episodes? How effective are police interrogation tactics at getting at the truth …

The Invisible Prison: Pathways And Prevention, Margaret F. Brinig, Marsha Garrison

Journal Articles

In this paper, we propose a new strategy for curbing crime and delinquency and demonstrate the inadequacy of current reform efforts. Our analysis relies on our own, original research involving a large, multi-generational sample of unmarried fathers from a rust-belt region of the United States as well as the conclusions of earlier researchers.

Our own research data are unusual in that they are holistic and multigenerational: The Court-based record system we utilized for data collection provided detailed information on child maltreatment, juvenile status and delinquency charges, child support, parenting time, orders of protection, and residential mobility for focal children (the …

Still Living After Fifty Years: A Census Of Judicial Review Under The Pennsylvania Constitution Of 1968, Seth F. Kreimer

All Faculty Scholarship

The year 2018 marked the fiftieth anniversary of the Pennsylvania Constitution of 1968. The time seems ripe, therefore, to explore the Pennsylvania Supreme Court’s exercise of judicial review under the 1968 Pennsylvania Constitution. This Article constitutes the first such comprehensive exploration.

The Article begins with an historical overview of the evolution of the Pennsylvania Constitution, culminating in the Constitution of 1968. It then presents a census of the 372 cases in which the Pennsylvania Supreme Court has vindicated distinctive Pennsylvania Constitutional rights under the Constitution of 1968.

Analysis of these cases leads to three conclusions:

1. Exercise of independent constitutional …

Strict Liability's Criminogenic Effect, Paul H. Robinson

All Faculty Scholarship

It is easy to understand the apparent appeal of strict liability to policymakers and legal reformers seeking to reduce crime: if the criminal law can do away with its traditional culpability requirement, it can increase the likelihood of conviction and punishment of those who engage in prohibited conduct or bring about prohibited harm or evil. And such an increase in punishment rate can enhance the crime-control effectiveness of a system built upon general deterrence or incapacitation of the dangerous. Similar arguments support the use of criminal liability for regulatory offenses. Greater punishment rates suggest greater compliance.

But this analysis fails …

Knowing Defense, Janet Moore, Andrew L.B. Davies

Faculty Articles and Other Publications

The field of empirical research on public defense is in an early stage of development. Yet the field is also diverse, as a growing community of researchers applies training in disciplines ranging from law and criminology to economics and social psychology. These facts invite reflection on baseline questions about the field that may inform future work. For example, what factors shape our research agendas? What data, methods, and theories are in play? Do these new research agendas align with the research priorities of public defenders and the communities they serve? Should they do so? To begin exploring such questions, this …

The Hidden Daubert Factor: How Judges Use Error Rates In Assessing Scientific Evidence, John B. Meixner Jr., Shari Seidman Diamond

Scholarly Works

In Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court provided a framework under which trial judges must assess the evidentiary reliability of scientific evidence whose admissibility is challenged. One factor of the Daubert test, the “known or potential rate of error” of the expert’s method, has received considerably less scholarly attention than the other factors, and past empirical study has indicated that judges have a difficult time understanding the factor and use it less frequently in their analyses as compared to other factors. In this paper, we examine one possible interpretation of the “known or potential rate of …

Does Criminal Diversion Contribute To The Vanishing Civil Trial?, John B. Meixner Jr., Shari Seidman Diamond

Scholarly Works

Through his seminal work on the vanishing trial, Professor Marc Galanter has had a profound impact on public and scholarly discourse about the role of the trial in litigation, documenting the sharp reductions in the rate of civil cases since the mid-twentieth century. While there is little remaining doubt that the American civil trial is an increasingly scarce commodity, there is still much debate as to what has caused the decline.

In this Article, we seek to explore the extent to which the federal criminal docket may be contributing to the rapid disappearance of the civil trial by taking priority …

Do Judges Vary In Their Treatment Of Race?, David S. Abrams, Marianne Bertrand, Sendhil Mullainathan

All Faculty Scholarship

Are minorities treated differently by the legal system? Systematic racial differences in case characteristics, many unobservable, make this a difficult question to answer directly. In this paper, we estimate whether judges differ from each other in how they sentence minorities, avoiding potential bias from unobservable case characteristics by exploiting the random assignment of cases to judges. We measure the between-judge variation in the difference in incarceration rates and sentence lengths between African-American and White defendants. We perform a Monte Carlo simulation in order to explicitly construct the appropriate counterfactual, where race does not influence judicial sentencing. In our data set, …

Studying Wrongful Convictions: Learning From Social Science, Richard A. Leo, Jon B. Gould

Richard A. Leo

There has been an explosion of legal scholarship on wrongful convictions in the last decade, reflecting a growing concern about the problem of actual innocence in the criminal justice system. Yet criminal law and procedure scholars have engaged in relatively little dialogue or collaboration on this topic with criminologists. In this article, we use the empirical study of wrongful convictions to illustrate what criminological approaches—or, more broadly, social science methods—can teach legal scholars. After briefly examining the history of wrongful conviction scholarship, we discuss the limits of the (primarily) narrative methodology of legal scholarship on wrongful convictions. We argue that …

Social Science And The Evolving Standards Of Death Penalty Law, Samuel R. Gross, Phoebe C. Ellsworth

Book Chapters

Unlike many of the topics covered in this book, death penalty litigation involves a wide variety of empirical issues. The Eighth Amendment of the U.S. Constitution provides that "Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishment inflicted." But what is a "cruel and unusual punishment?" It could be a punishment that is morally unacceptable to the American people, like cutting off noses or hands. Following the other clauses of the amendment, it could be a punishment that is excessive, in that a lesser penalty would achieve the same ends. For example, if a …

The Law Is Not The Case: Incorporating Empirical Methods Into The Culture Of Case Analysis, Kay L. Levine

Faculty Articles

While I consider case analysis in the context of cultural defense jurisprudence, this Essay should be regarded as a case study of a more endemic problem in legal scholarship. In tackling such an area, my goal is not to overthrow centuries of legal analysis, but rather to explore how we, as legal scholars, might use social science techniques to more systematically investigate, document, analyze, and predict the state of a particular comer of the legal universe.

The argument proceeds in two parts. Part II considers empirical approaches to the question raised by Lee: how might we ascertain the relationship between …
