Of Bass Notes And Base Rates: Avoiding Mistaken Inferences About Copying, Christopher Buccafusco, Rebecca Tushnet
Of Bass Notes And Base Rates: Avoiding Mistaken Inferences About Copying, Christopher Buccafusco, Rebecca Tushnet
Faculty Scholarship
To prove copyright infringement, a plaintiff must convince a jury that the defendant copied from the plaintiff’s work rather than independently creating it. To prove copying, especially cases involving music, it’s common for plaintiffs and their experts to argue that the similarities between the parties’ creative works are so great that it is simply implausible that the defendant’s work was created without copying from the plaintiff’s work. Unfortunately, in its present form, the argument is mathematically illiterate: It assumes, without any underlying evidence, that the experts know or could reasonably estimate how likely it is that a song with similarity …

Forensic Science In Legal Education, Brandon L. Garrett, Glinda S. Cooper, Quinn Beckham
Faculty Scholarship
In criminal cases, forensic science reports and expert testimony play an increasingly important role in adjudication. More states now follow a federal reliability standard, following Daubert v. Merrell Dow Pharmaceuticals and Rule 702, which calls upon judges to assess the reliability and validity of such scientific evidence. Little is known about what education law schools provide regarding forensic and scientific evidence or what types of specialized training they receive on scientific methods or evidence. Whether law schools have added forensic science courses to their curricula in recent years was not known. To better understand the answers to those questions, in …

The Proficiency Of Experts, Brandon L. Garrett, Gregory Mitchell
The Proficiency Of Experts, Brandon L. Garrett, Gregory Mitchell
Faculty Scholarship
Expert evidence plays a crucial role in civil and criminal litigation. Changes in the rules concerning expert admissibility, following the Supreme Court's Daubert ruling, strengthened judicial review of the reliability and the validity of an expert's methods. Judges and scholars, however, have neglected the threshold question for expert evidence: whether a person should be qualified as an expert in the first place. Judges traditionally focus on credentials or experience when qualifying experts without regard to whether those criteria are good proxies for true expertise. We argue that credentials and experience are often poor proxies for proficiency. Qualification of an expert …

Forensics And Fallibility: Comparing The Views Of Lawyers And Jurors, Brandon L. Garrett, Gregory Mitchell
Forensics And Fallibility: Comparing The Views Of Lawyers And Jurors, Brandon L. Garrett, Gregory Mitchell
Faculty Scholarship
Forensic evidence plays an increasingly prominent role in criminal practice, leading some to worry that depictions in popular media might make jurors over-reliant on forensics — a so-called CSI effect. There is little empirical evidence of such a CSI effect among jury-eligible laypersons; any such influence also depends upon a case proceeding to a trial. As the Supreme Court has put it: “criminal justice today is for the most part a system of pleas, not a system of trials.” However, a CSI effect could be more consequential if it affects how criminal lawyers assess forensic evidence when they negotiate pleas …
How Jurors Evaluate Fingerprint Evidence: The Relative Importance Of Match Language, Method Information, And Error Acknowledgment, Brandon L. Garrett, Gregory Mitchell
How Jurors Evaluate Fingerprint Evidence: The Relative Importance Of Match Language, Method Information, And Error Acknowledgment, Brandon L. Garrett, Gregory Mitchell
Faculty Scholarship
Fingerprint examiners use a variety of terms and phrases to describe a finding of a match between a defendant's fingerprints and fingerprint impressions collected from a crime scene. Despite the importance and ubiquity of fingerprint evidence in criminal cases, no prior studies examine how jurors evaluate such evidence. We present two studies examining the impact of different match phrases, method descriptions, and statements about possible examiner error on the weight given to fingerprint identification evidence by laypersons. In both studies, the particular phrase chosen to describe the finding of a match-whether simple and imprecise or detailed and claiming near certainty-had …

Invalid Forensic Science Testimony And Wrongful Convictions, Brandon L. Garrett, Peter J. Neufeld
Invalid Forensic Science Testimony And Wrongful Convictions, Brandon L. Garrett, Peter J. Neufeld
Faculty Scholarship
This is the first study to explore the forensic science testimony by prosecution experts in the trials of innocent persons, all convicted of serious crimes, who were later exonerated by post-conviction DNA testing. Trial transcripts were sought for all 156 exonerees identified as having trial testimony by forensic analysts, of which 137 were located and reviewed. These trials most commonly included testimony concerning serological analysis and microscopic hair comparison, but some included bite mark, shoe print, soil, fiber, and fingerprint comparisons, and several included DNA testing. This study found that in the bulk of these trials of innocent defendants - …
Competition In The Courtroom: When Does Expert Testimony Improve Jurors’ Decisions?, Cheryl Boudreau, Mathew D. Mccubbins
Competition In The Courtroom: When Does Expert Testimony Improve Jurors’ Decisions?, Cheryl Boudreau, Mathew D. Mccubbins
Faculty Scholarship
Many scholars lament the increasing complexity of jury trials and question whether the testimony of competing experts helps unsophisticated jurors to make informed decisions. In this article, we analyze experimentally the effects that the testimony of competing experts has on (1) sophisticated versus unsophisticated subjects' decisions and (2) subjects' deci- sions on difficult versus easy problems. Our results demonstrate that competing expert testimony, by itself, does not help unsophisticated subjects to behave as though they are sophisticated, nor does it help subjects make comparable decisions on difficult and easy problems. When we impose additional institutions (such as penalties for lying …
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins
Faculty Scholarship
Many scholars debate whether a competition between experts in legal, political, or economic contexts elicits truthful information and, in turn, enables people to make informed decisions. Thus, we analyze experimentally the conditions under which competition between experts induces the experts to make truthful statements and enables jurors listening to these statements to improve their decisions. Our results demonstrate that, contrary to game theoretic predictions and contrary to critics of our adversarial legal system, competition induces enough truth telling to allow jurors to improve their decisions. Then, when we impose additional institutions (such as penalties for lying or the threat of …

Recent research—in which subjects were studied longitudinally from childhood until adulthood—has started to clarify how a child’s environment and genetic makeup interact to create a violent adolescent or adult. For example, male subjects who were born with a particular allele of the monoamine oxidase A gene and also were maltreated as children had a much greater likelihood of manifesting violent antisocial behavior as adolescents and adults. Also, individuals who were born with particular alleles of the serotonin transporter gene and also experienced multiple stressful life events were more likely to manifest serious depression and suicidality. This research raises the question …

Behavioural Genetics In Criminal Cases: Past, Present And Future, Nita A. Farahany, William Bernet
Faculty Scholarship
Researchers studying human behavioral genetics have made significant scientific progress in enhancing our understanding of the relative contributions of genetics and the environment in observed variations in human behavior. Quickly outpacing the advances in the science are its applications in the criminal justice system. Already, human behavioral genetics research has been introduced in the U.S. criminal justice system, and its use will only become more prevalent. This essay discusses the recent historical use of behavioral genetics in criminal cases, recent advances in two gene variants of particular interest in the criminal law, MAOA and SLC6A4, the recent expert testimony on …
Specialized Trial Courts: Concentrating Expertise On Fact, Arti K. Rai
Specialized Trial Courts: Concentrating Expertise On Fact, Arti K. Rai
Faculty Scholarship
In the absence of a specialized patent trial court with expertise in fact-finding, the Court of Appeals for the Federal Circuit often reviews de novo the many factual questions that pervade patent law. De novo review of fact by an appellate court is problematic. In the area of patent law, as in other areas of law, there are sound institutional justifications for the conventional division of labor that gives trial courts primary responsibility for questions of law. This Article identifies the problems created by de novo appellate review of fact and argues for the creation of a specialized trial court …
