Neuroscience, Cognitive Psychology, and theCriminal Justice SystemINTRODUCTIONDeborah W. Denno*, Guest EditorThis symposium on the linking of neuroscience, cognitive psychology, andlaw derives from a spectacular panel organized for the 2009 Annual Meeting of theAssociation of American Law Schools (AALS) by Susan Bandes, under theauspices of David Harris and the executive board of the AALS Section onCriminal Justice.' Fortunately for the Ohio State Journal of Criminal Law, theAALS Criminal Justice Section panel members graciously accepted the Journal'sinvitation to publish their articles in this issue, thereby providing an indeliblecontribution to a fast-growing field. Although this symposium is one of a numberof projects on neuroscientific approaches to the legal system that have beenorganized over the years, readers will see something very different in the articlesthat follow. The contributions cover a distinctively important niche-a pragmaticfocus on the practices of key law enforcement actors, namely the police,prosecutors, and punishers in the criminal justice community. By examining thedecision-making of these individuals and groups in real world circumstances,through a range of brain sciences, the symposium's authors enhance the value thatany single scientific discipline can give while also offering proposals that could beimplemented immediately.Such efforts can, of course, be laden with controversy. Cognitiveneuroscience is a booming enterprise, either well-or ill-suited to law, dependingon one's perspective.2 As Professor Bandes's conclusion recounts, the AALSpanel probed the complexity of this law-science merger with three goals in mind:to examine the interrelationship between neuroscience and substantive criminallaw; to incorporate criminal procedure more directly into the examination in a waythat past investigations have not done; and to scrutinize cognitive bias in decision-* Arthur A.

For example, neuroscienceis "the branch of the life sciences that studies the brain and nervous system ...includ[ing] brain processes such as sensation, perception, learning, memory, andmovement."5 Cognitive psychology is a branch of the psychological sciences thatexamines cognition, a term that "collectively refers to a variety of higher mentalprocesses such as thinking, perceiving, imagining, speaking, acting and planning."The combined field of cognitive neuroscience "is a bridging discipline betweencognitive science and cognitive psychology, on the one hand, and biology andneuroscience, on the other,"7 originated in response to modern advances in brainmeasurements. While the substantive overlap between neuroscience and cognitivepsychology is obvious, their methodology and techniques of measurement, not tomention history and overall orientation, can be profoundly different. The creationof cognitive neuroscience was intended to gain strength from such variations, but ittoo is not without its detractors.9 This symposium's authors do a good job ofavoiding the mire of potential interdisciplinary conflict as well as recognizing thelimits of applying any brain science to law.An investigation of the criminal justice system typically begins, of course,with the police.

Effortsto comprehend the sources and operation of such psychological forces shouldenable the creation of mechanisms for containing the errors and biases that mayresult.Taslitz begins by discussing the two ways that Fourth Amendment error canoccur: first, by ensnaring the guilty by "pure luck" rather than by constitutionalevidentiary dictates, and second, by searching or seizing innocent parties or, at aminimum, those selected without evidence." Such mistakes appear with somefrequency and their potential consequences are substantial. According to Taslitz, aparticularized inquiry requirement, which involves a duty to investigate andevaluate evidence carefully, may reduce much of this error. At the same time,enforcing such a requirement contravenes an academic trend that hails the value ofpolice intuition and hunches-a perspective which, in Taslitz's eyes, has benefitsbut also drawbacks because intuitions can be biased and erroneous. Taslitzrecommends instead that "intuitive decision making" by police complement, notreplace, more conscious "systematic thinking," which is characterized by rules andguidelines that promote accountability and justified decision-making.12Relying upon voluminous and cutting-edge research, Taslitz accomplishes atour de force investigation of police competency in producing the constitutionallyrequired individualized suspicion judgment, especially in the context of the quickdecisions made by "street cops,"' 3 the police on the beat who perform the greatmajority of warrantless U.S. searches, seizures, stops, and arrests. In so doing,Taslitz analyzes studies on the capacity to form accurate initial conclusions aboutothers, spanning from information on how first impression judgments are made (byboth police and civilians) to the cognitive impact of a range of influences,including individual facial features, fundamental attribution error, cognitive load,empathy, and resistance to changing first impressions. Taslitz balances hisargument by also providing an overview of the advantages of intuitive thinking bypolice, such as the ability to recognize behavioral patterns and anomalies whilecurbing complacency and rigidity. By constructing a cost-benefit analysis basedon the plusses and minuses of both systematic and intuitive thinking processes,Taslitz argues for a requirement that police provide specific facts to validate theirjudgments and individualize suspicion so that the suspicion can be tied to aparticular person or place. This goal encompasses a duty to investigate bolstered"o Andrew E.

Id. at 13.2010] 3OHIO STATE JOURNAL OF CRIMINAL LAWby the additional duties of reasonably evaluating the information that is acquiredand reasonably explaining the actions the police have taken. Overall, Taslitz'spiece is an exemplary application of psychological research to police decision-making because it demonstrates how the challenges of human cognition canconflict with the legal system's goals of justice and fairness, even as our instinctsand intuitions can also help us rapidly respond to challenges.Such themes also resonate with other criminal justice actors and decision-making issues, as Alafair Burke so eloquently argues in ProsecutorialAgnosticism.14 According to Professor Burke, most legal ethicists and prosecutorsembrace the prevailing view that an ethical prosecutor should act as a "supremejuror" and pursue criminal charges only against those defendants the prosecutorperceives as guilty beyond a reasonable doubt.'5 This precept holds even though,as a constitutional matter, a prosecutor need only show probable cause (anobjective standard divorced from the prosecutor's personal beliefs about guilt).Ethical rules that govern prosecutors are similarly undemanding.Burke challenges the notion of prosecutor as supreme juror by examiningspecific cases and hypotheticals that prosecutors regularly pursue even when theyare personally uncertain of a defendant's guilt, noting that courts also haveencouraged prosecutors to engage in inconsistent charging decisions. LikewiseBurke dismisses arguments raised by proponents of the supreme juror requirementthat prosecutors are acting ethically as long as they are assured that a defendantwas factually involved in an incident, as opposed to the unethical-actingprosecutors who press charges despite their doubts that they are implicating theright person. According to Burke, this so-called distinction between factual andlegal guilt is wrong both descriptively and normatively, often resting on fragilejustifications such as the belief that the defendant is guilty of something if not ofthe specific crime charged. Indeed, not only do prosecutors routinely pursuecharges against defendants with questionable legal guilt, but there are also goodreasons why this prosecutorial perspective could result in charges againstdefendants with questionable factual guilt.With the support of cognitive science literature, Burke contends that, contraryto popular belief, agnostic prosecutors may protect the innocent more effectivelythan supreme juror prosecutors whose guilt-seeking focus and tunnel vision mayresult in a range of behavioral and perceptual biases. These biases includeselective information processing, which starts when the prosecutor believes in thedefendant's guilt, and the resulting failure to identify exculpatory evidence orrevisit a conclusion. Likewise, this bias has reverberating effects given thatjudges, jurors, and other prosecutors heavily rely on the initial prosecutor'sscreening and belief in the guilt of the defendant and therefore may be less diligentin forming their own conclusions. Prosecutors would be more fair if they served as"vigilant agnostics" in light of evidence demonstrating the extent to which14 Alafair S. Burke, ProsecutorialAgnosticism, 8 OHIo ST. J. CluM. L. 79 (2010)."s Id. at 79-80.4 [Vol 8: 1NEUROSCIENCE AND COGNITIVE PSYCHOLOGYpersonal viewpoints can impair neutrality.' 6 Overall, then, Burke provides a highlynuanced and persuasive integration of practical lawyering and empirical cognitiveresearch to demonstrate the dangers of prosecutors' personal beliefs on decision-making, as well as to call into question the supreme juror requirement.A comparably compelling article is John Darley's account of the cognitivebiases of punishers which he presents in Citizens' Assignments of Punishment forMoral Transgressions: A Case Study in the Psychology of Punishment.17 InCitizens'Assignments of Punishment, Darley uses research from neuroscience andcognitive psychology to examine the moral judgments involved in an individual's"punishment impulse," specifically an individual's motivation for assigning aparticular level of punishment to the wrongful actions of another person. ' Darleyalso investigates the extent to which people's intuitive levels of punitiveness canbe modified. For example, if the punishment impulse is not static and citizens arecapable of altering their opinions about the degree of punishment they think othersdeserve, then the harsh sentences in the United States can start to decline andcriminal justice practices can become more humane.In a clever assessment of these dynamics, Darley relies on studies conductedusing one of two major paradigms: "sentencing scenario" or "experimentalgame."l9 Some of these studies included neural imaging of brain processes, whichallowed localization of the brain areas involved in the decision making. Theresults were analyzed according to classic theories of punishment (e.g., retribution,incapacitation, utilitarianism). In sentencing scenario studies, a respondent readsbrief hypotheticals in which an actor has committed a moral wrong that therespondent can either exculpate or punish according to a specified scale ofseriousness (for example, a certain number of years in prison). In experimentalgame studies, on the other hand, two or more respondents face intricate dilemmas,typically computerized, in which respondents are able to impose fine-basedpunishments on other respondents for behaviors that they view as moral violations.Differing trust situations are tested and all respondents are anonymous so that any"retaliatory responses" 20 that one respondent feels toward another will not beaffected by personal feelings or ties. Research results from both the sentencingscenario and experimental game paradigms can then be examined via a dualprocess theory that frames the two types of decisions that study respondents canmake-either reasoned decisions (which follow rules and implicate abstract areasof the brain) or intuitive decisions (which occur automatically and without6 Id. at 80-81.17 John M.

While experimental gamestudies report similar kinds of results, they reveal an added feature: respondents areactually willing to inflict real punishments on other people (an outcome that canonly be surmised from sentencing scenario studies). Darley's discussion of theimplications of these results also incorporates a thorough evaluation of other, moretraditional, psychological research such as that conducted on the sentencingdecisions of magistrates and judges. In so doing, Darley takes a striking stand:retributive punitiveness is not inevitable. There is evidence, for example, that bothindividuals and groups have made conscious efforts to engage in reasoned (ratherthan intuitive) decisions about the punishments they intend to inflict on others andtherefore act independently of culturally punitive pressures. Likewise, individualsare able to learn more humane methods of practicing criminal justice or,alternatively, substituting just-deserts intuition with forgiveness or restorativejustice. In sum, then, Darley concludes a superb piece with a message deliveredfrom science to law: while research shows people lean toward retaliation in theirmoral judgments, those people can change. And so can our criminal justicesystem.This symposium's articles on neuroscience, cognitive psychology, and thecriminal justice system provide a comprehensive and evenhanded perspective onthe topic in the context of the critical decisions made daily by different lawenforcement actors. May this forum be the first of many on this interdisciplinaryrelationship.21 Id. at 113.6[Vol 8:1
