Something Doesn’T Add Up: Solving Dna Forensic Science Statistical Fallacies In Trial Testimony, Kendall Brooke Kilberger

Vanderbilt Journal of Entertainment & Technology Law

While the limitations of traditional forensic sciences are generally recognized, the presentation of DNA forensic science statistical testimony has widely evaded criticism. This lack of oversight has allowed four DNA forensic science statistical fallacies to plague the legal system: providing statistics without empirical support, the individualization fallacy, the prosecutor’s fallacy, and the defense attorney’s fallacy. These fallacies pose a significant risk to the preservation of justice, as erroneous DNA forensic science statistical testimony plays a critical role in wrongfully convicting innocent defendants.

This Note suggests administering standard jury instructions every time DNA forensic science statistical testimony is presented during trial. …

“Statistics Are Human Beings With The Tears Wiped Away”: Utilizing Data To Develop Strategies To Reduce The Number Of Native Americans Who Go Missing, Lori Mcpherson, Sarah Blazucki

Seattle University Law Review

On New Year’s Eve night, 2019, sixteen-year-old Selena Shelley Faye Not Afraid attended a party in Billings, Montana, about fifty miles west of her home in Hardin, Montana, near the Crow Reservation. A junior at the local high school, she was active in her community. The party carried over until the next day, and she caught a ride back toward home with friends in a van the following afternoon. When the van stopped at an interstate rest stop, Selena got out but never made it back to the van. The friends reported her missing to the police and indicated they …

Science And The Eighth Amendment, Meghan J. Ryan

Faculty Journal Articles and Book Chapters

As time hurtles forward, new science constantly emerges, and many scientific fields can shed light on whether a punishment is unconstitutionally cruel and unusual, or even on whether bail or fines are unconstitutionally excessive under the Eighth Amendment. In fact, in recent years, science has played an increasingly important role in the Court’s Eighth Amendment jurisprudence. From the development of an offender’s brain, to the composition of lethal injection drugs, even to measurements of pain, knowledge of various scientific fields is becoming central to understanding whether a punishment is unconstitutionally cruel and unusual. There are a number of limits to …

Title 2.0: Discrimination Law In A Data-Driven Society, Bryan Casey

Journal of Law and Mobility

More than a quarter century after civil rights activists pioneered America’s first ridesharing network, the connections between transportation, innovation, and discrimination are again on full display. Industry leaders such as Uber, Amazon, and Waze have garnered widespread acclaim for successfully combatting stubbornly persistent barriers to transportation. But alongside this well-deserved praise has come a new set of concerns. Indeed, a growing number of studies have uncovered troubling racial disparities in wait times, ride cancellation rates, and service availability in companies including Uber, Lyft, Task Rabbit, Grubhub, and Amazon Delivery.

Surveying the methodologies employed by these studies reveals a subtle, but …

Lawyer As Soothsayer: Exploring The Important Role Of Outcome Prediction In The Practice Of Law, Mark K. Osbeck

Articles

Outcome prediction has always been an important part of practicing law. Clients rely heavily on their attorneys to provide accurate assessments of the potential legal consequences they face when making important decisions (such as whether to accept a plea bargain, or risk a conviction on a much more serious offense at trial). And yet, notwithstanding its enormous importance to the practice of law (and notwithstanding the handsome legal fees it commands), outcome prediction in the law remains a very imprecise endeavor. The reason for this inaccuracy is that the three principal tools lawyers have traditionally relied on to facilitate outcome …

Controlling The Jury-Teaching Function, Richard D. Friedman

Articles

When evidence with a scientific basis is offered, two fundamental questions arise. First, should it be admitted? Second, if so, how should it be assessed? There are numerous participants who might play a role in deciding these questions—the jury (on the second question only), the parties (through counsel), expert witnesses on each side, the trial court, the forces controlling the judicial system (which include, but are not limited to, the appellate courts), and the scientific establishment. In this Article, I will suggest that together, the last two—the forces controlling the judicial system and the scientific establishment—have a large role to …

Problems With Using Statistics To Justify Institutional Policies, Justin Shin

Senior Projects Spring 2017

It is becoming increasingly common for institutions to use statistics to inform policy decisions. We should be prepared to ask ourselves what regulatory principles should be imposed on institutions that seek to justify certain policies through deference to a statistical analysis. This paper will examine the difficulties that come with using statistics to justify actions, and argue that certain standards of transparency and verifiability should be expected from any institution that seeks to involve a statistical analysis in the formation of policies. I will first use Market Share Liability, an established use of statistics, to draw out what responsibilities an …

The Discoverability Of E-Mails: The Smoking Gun Of The Modern Era, Michael J. Martin

University of Massachusetts Law Review

The discoverability of e-mails is an area of law that every modern day lawyer must be familiar with in order to avoid the risk of being sanctioned. Over the past years, courts have awarded sanctions to moving parties at a steadily increasing pace. These sanctions have included adverse jury instructions, default judgements, attorney's fees, large monetary fines, and in one instance, a jail sentence. Courts have sent the message that improper conduct will not be tolerated in this developing area of law by not hesitating to order sanctions. Thus, it is essential that modern day lawyers become acquainted with the …

Machine Learning And Law, Harry Surden

Publications

This Article explores the application of machine learning techniques within the practice of law. Broadly speaking “machine learning” refers to computer algorithms that have the ability to “learn” or improve in performance over time on some task. In general, machine learning algorithms are designed to detect patterns in data and then apply these patterns going forward to new data in order to automate particular tasks. Outside of law, machine learning techniques have been successfully applied to automate tasks that were once thought to necessitate human intelligence — for example language translation, fraud-detection, driving automobiles, facial recognition, and data-mining. If performing …

Significant Statistics: The Unwitting Policy Making Of Mathematically Ignorant Judges, Michael I. Meyerson, William Meyerson

All Faculty Scholarship

This article will explore several areas in which judges, hampered by their mathematical ignorance, have permitted numerical analysis to subvert the goals of our legal system. In Part II, I will examine the perversion of the presumption of innocence in paternity cases, where courts make the counter-factual assumption that regardless of the evidence, prior to DNA testing, a suspect has a 50/50 chance of being the father. In Part III, I will explore the unnecessary injection of race into trials involving the statistics of DNA matching, even when race is entirely irrelevant to the particular case. Next, in Part IV, …

Measuring The Next 30 Years, Beth Locker, Andrew Barclay

University of Michigan Journal of Law Reform

The last thirty years have seen many changes in the field of child protection, as child welfare law and policy have been undergoing nearly constant change. Those changes, however, have rarely been supported by data or scientific research; rather, they seem to have been largely driven by individual perception of events and gut instincts resulting in what has become essentially a folklore-based system. By focusing on data and scientific research, we hope for better outcomes, but short of that, we at least hope to know whether, and why, outcomes change. The move towards data collection and analysis has begun, but …

Bayes' Law, Sequential Uncertainties, And Evidence Of Causation In Toxic Tort Cases, Neal C. Stout, Peter A. Valberg

University of Michigan Journal of Law Reform

Judges are the gatekeepers of evidence. Arguably, the most difficult duty for a judicial gatekeeper is to screen the reliability of expert opinions in scientific fields such as medicine that are beyond the ken of most judges. Yet, judges have a duty to scrutinize such expert opinion evidence to determine its reliability and admissibility. In toxic tort cases, the issue of causation-whether the alleged exposures actually caused the plaintiffs injury-is nearly always the central dispute, and determining admissibility of expert causation opinion is a daunting challenge for most judges. We present a comprehensive review of the courts' struggles with the …

Dna As Evidence: Viewing Science Through The Prism Of The Law, Peter Donnelly, Richard D. Friedman

Articles

In this article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council (NRC) have been badly mistaken in their analysis of this problem. The mistakes are significant because the reports have carried great authority with American courts; moreover, the DNA Advisory Board of the FBI has endorsed the second …

Dna Database Searches And The Legal Consumption Of Scientific Evidence, Peter Donnelly, Richard D. Friedman

Articles

DNA evidence has transformed the proof of identity in criminal litigation, but it has also introduced daunting problems of statistical analysis into the process. In this Article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council ("NRC"), each of which has carried great authority with the American courts on …

Roundtable Discussion: Science, Environment, And The Law, James E. Krier

Articles

Science, environment, and the law is our topic. The problem of interest to me has to do with risk regulation and, more particularly, with the fact that technical and scientific views of risk differ dramatically from lay or public views. How is this conflict to be managed and resolved? I have to go through my account very quickly, given the time constraint, so let me mention that it is based on an article that sets out my arguments at length.'

Law And Quantitative Multivariate Analysis: An Encounter, Arnold H. Lozowick, Peter O. Steiner, Roger Miller

Michigan Law Review

This Article chronicles one attempt to blend the sophisticated science of statistics with the mysterious art of the law in an antitrust case. Once again, we hope to provide lawyers with an understanding of a tool which can be used in resolving complex factual questions wherever they arise, not merely in an antitrust context. Although the lawyer will not emerge from this encounter as an accomplished statistician or economist, he may be able to talk to his fellow social scientists and to achieve a more fruitful application of social science techniques to the law.

Radiation Injuries And Statistics: The Need For A New Approach To Injury Litigation, Samuel D. Estep

Michigan Law Review

The emphasis given by the mass media of communication to some of the dramatic problems arising from the use of nuclear energy unfortunately has diverted attention from some of the matters about which something can be done by lawyers, administrators, and legislators without the necessity of complicated international negotiations between various parties to the "Cold War." The headlines leave the uninformed, and perhaps often also the informed, public with the impression that even for radiation injuries the important problems all deal with such questions as: (1) Will only a few or many millions of people survive an all-out nuclear war? …
