The Problems With Decision-Making, Joanna K. Sax
The Problems With Decision-Making, Joanna K. Sax
Faculty Scholarship
Our society faces major challenges in numerous areas, including climate change and healthcare. Addressing these problems with technological advances are of great importance. Increasingly, however, consumers are resisting or rejecting such technological interventions based on inappropriate assignment of risk. In other words, the consumer assessment of risk is not in line with evidence-based assessment of risk. This article focuses on two controversial areas, vaccines and genetically engineered food, as examples in which consumers assign a high risk despite an evidence-based assessment of low risk. This article describes how empirically tested decision-making theories explain why consumers inappropriately assign risk. While these …
Nudges That Should Fail?, Avishalom Tor
Nudges That Should Fail?, Avishalom Tor
Journal Articles
Professor Sunstein (2017) discusses possible causes for and policy implications of the failure of nudges, with a special attention to defaults. Though he focuses on nudges that fail when they should succeed, Sunstein recognizes that some failures reveal that a nudge should not have been attempted to begin with. Nudges that fail, however, does not consider fully the relationship between the outcomes of nudging and their likely welfare effects, most notably neglecting the troubling case of nudges that succeed when they should fail. Hence, after clarifying the boundaries of legitimate nudging and noting the fourfold relationship between the efficacy of …
The Disruptive Neuroscience Of Judicial Choice, Anna Spain Bradley
The Disruptive Neuroscience Of Judicial Choice, Anna Spain Bradley
Publications
Scholars of judicial behavior overwhelmingly substantiate the historical presumption that most judges act impartially and independent most of the time. The reality of human behavior, however, says otherwise. Drawing upon untapped evidence from neuroscience, this Article provides a comprehensive evaluation of how bias, emotion, and empathy—all central to human decision-making—are inevitable in judicial choice. The Article offers three novel neuroscientific insights that explain why this inevitability is so. First, because human cognition associated with decision-making involves multiple, and often intersecting, neural regions and circuits, logic and reason are not separate from bias and emotion in the brain. Second, bias, emotion, …
Cognitive Competence In Executive-Branch Decision Making, Anna Spain Bradley
Cognitive Competence In Executive-Branch Decision Making, Anna Spain Bradley
Publications
The decisions Presidents and those operating under their authority take determine the course of our nation and the trajectory of our lives. Consequently, understanding who has the power and authority to decide has captured both the attention of legal scholars across a variety of fields for many years and the immediate worry of the public since the 2016 Presidential election. Prevailing interventions look for ways that law can offer procedural and institutional reforms that aim to maintain separation of powers and avoid an authoritarian regime. Yet, these views commonly overlook a fundamental factor and a more human one: the individuals …
It Must Have Been Him: Coherence Effects Within The Legal System, Jonathan N. Carbone
It Must Have Been Him: Coherence Effects Within The Legal System, Jonathan N. Carbone
FIU Electronic Theses and Dissertations
The present series of studies examine how jurors and public defenders evaluate different pieces of evidence and integrate them into a coherent conclusion within the context of a criminal case. Previous research has shown that in situations where both sides of the case are compelling, decision-makers nevertheless come to highly confident and polarized decisions, called coherence shifts (Simon, 2004). The present research sought to expand on coherence effects, improve upon the methodology of previous studies, and explore potential moderators of coherence. In Study 1, mock jurors (n = 306) read about a criminal case and evaluated multiple pieces of …

President Obama charged the Presidential Commission for the Study of Bioethical Issues to identify a set of core ethical standards in the neuroscience domain, including the appropriate use of neuroscience in the criminal-justice system. The Commission, in turn, called for comments and recommendations. The MacArthur Foundation Research Network on Law and Neuroscience submitted a consensus statement, published here, containing 16 specific recommendations. These are organized within three main themes: 1) what steps should be taken to enhance the capacity of the criminal justice system to make sound decisions regarding the admissibility and weight of neuroscientific evidence?; 2) to what extent …
Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
Book Chapters
Policy makers typically approach human behavior from the perspective of the rational agent model, which relics on normativc, a priori analyses. The model assumes people make insightful, well-planned, highly controlled, and calculated decisions guided by considerations of personal utility. This perspective is promoted in the social sciences and in professional schools and has come to dominate much of the formulation and conduct of policy. An alternative view, developed mostly through empirical behavioral research, and the one we will articulate here, provides a substantially difierent perspective on individual behavior and its policy and regulatory implications. According to the empirical perspective, behavior …
Legal Reasoning And Scientific Reasoning, Phoebe C. Ellsworth
Legal Reasoning And Scientific Reasoning, Phoebe C. Ellsworth
Articles
In my presentation for the 2010 Meador Lectures on Rationality, I chose to compare legal reasoning and scientific reasoning. Both law and science pride themselves on the rationality of their intellectual methods and believe that those methods are designed to analyze questions and reach the correct conclusions by means of reason, free from cognitive or emotional biases. Of course, both law and science often fall short of this ideal at all levels, from the decisions about individual legal cases or scientific studies to the acceptance of general theories. In many ways, the biases that mislead legal and scientific thinkers are …
Ask And What Shall Ye Receive? A Guide For Using And Interpreting What Jurors Tell Us, Barbara O'Brien, Samuel R. Sommers, Phoebe C. Ellsworth
Ask And What Shall Ye Receive? A Guide For Using And Interpreting What Jurors Tell Us, Barbara O'Brien, Samuel R. Sommers, Phoebe C. Ellsworth
Articles
We review the extensive body of studies relying on jurors' self-reports in interviews or questionnaires, with a focus on potential threats to validity for researchers seeking to answer particularly provocative questions such as the influence of race in jury decision-making. We then offer a more focused case study comparison of interview and questionnaire data with behavioral data in the domain of race and juror decision-making. Our review suggests that the utility of data obtained from juror interviews and questionnaire responses varies considerably depending on the question under investigation. We close with an evaluation of the types of empirical questions most …
Happiness, Efficiency, And The Promise Of Decisional Equity: From Outcome To Process, Jeffrey L. Harrison
Happiness, Efficiency, And The Promise Of Decisional Equity: From Outcome To Process, Jeffrey L. Harrison
UF Law Faculty Publications
This article explains why outcome-oriented goals like efficiency, happiness, or well-being are ultimately of limited use as goals for law. Part II places happiness research in the context of past efforts to assess efficiency standards. Part III outlines the schism between efficiency and happiness and examines whether they can be reconciled. Part IV discusses the problems of relying on direct measures of happiness. The concept of decisional equity is described and examined in Part V.
The Case For Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
The Case For Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
Book Chapters
Policymakers approach human behavior largely through the perspective of the “rational agent” model, which relies on normative, a priori analyses of the making of rational decisions. This perspective is promoted in the social sciences and in professional schools, and has come to dominate much of the formulation and conduct of policy. An alternative view, developed mostly through empirical behavioral research, provides a substantially different perspective on individual behavior and its policy implications. Behavior, according to the empirical perspective, is the outcome of perceptions, impulses, and other processes that characterize the impressive machinery that we carry behind the eyes and between …
Behaviorally Informed Financial Services Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
Behaviorally Informed Financial Services Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir
Other Publications
Financial services decisions can have enourmous consequences for household well-being. Households need a range of financial services - to conduct basic transactions, such as receiving their income, storing it, and paying bills; to save for emergency needs and long-term goals; to access credit; and to insure against life's key risks. But the financial services system is exceedingly complicated and often not well-designed to optimize house-hold behavior. In response to the complexity of out financial system, there has been a long running debate about the appropriate role and form of regulation. Regulation is largely stuck in two competing models - disclosure, …
Risk Realization, Emotion, And Policy Making, Chris Guthrie
Risk Realization, Emotion, And Policy Making, Chris Guthrie
Vanderbilt Law School Faculty Publications
In their study of terrorism and SARS, Professor Feigenson and his colleagues report "significant positive correlations between people's risk perceptions and their negative affect." In their review of the judgment and decision-making literature, Professor Slovic and his colleagues document the interplay between reason and emotion in assessing risk. And in the context of a soldier's concerns for himself and his family, Professor Moran provides a powerful narrative of fear. But what happens when such threats are actually realized? Do we accurately predict the emotional impact of such events? Or are there meaningful and predictable differences between the feelings we forecast …
Prospect Theory, Risk Preference, And The Law, Chris Guthrie
Prospect Theory, Risk Preference, And The Law, Chris Guthrie
Vanderbilt Law School Faculty Publications
To understand how people behave in an uncertain world - and to make viable recommendations about how the law should try to shape that behavior - legal scholars must employ a model or theory of decision making. Only with an understanding of how people are likely to respond to legal rules can legal scholars, judges, legislators, and regulators craft rules that are likely to encourage desirable behavior and discourage undesirable behavior. Rather than rely on rational choice theory, behavioral law and economics scholars (or legal decision theorists) have turned to Daniel Kahneman and Amos Tversky's "prospect theory" to inform their …
Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth
Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth
Book Chapters
Most research that has attempted to predict verdict preferences on the basis of stable juror characteristics, such as attitudes and personality traits, has found that individual differences among jurors are not very useful predictors, accounting for only a small proportion of the variance in verdict choices. Some commentators have therefore concluded that verdicts are overwhelmingly accounted for by "the weight of the evidence," and that differences among jurors have negligible effects. But there is a paradox here: In most cases the weight of the evidence is insufficient to produce firstballot unanimity in the jury (Hans & Vidmar, 1986; Hastie, Penrod, …
How Much Do We Really Know About Race And Juries? A Review Of Social Science Theory And Research, Samuel R. Sommers, Phoebe C. Ellsworth
How Much Do We Really Know About Race And Juries? A Review Of Social Science Theory And Research, Samuel R. Sommers, Phoebe C. Ellsworth
Articles
The past decade has witnessed numerous high-profile criminal trials in which controversial verdicts have been attributed to racethe race of the defendant, the racial composition of a jury, an attorney "playing the race card," and so on. A predominantly Black jury's acquittal of O.J. Simpson and White jurors' leniency in the police brutality cases of Rodney King and Amadou Diallo not only sparked public debate, but also led to rioting and violence. In the wake of trials such as these, many have questioned the viability of the American jury system.' More specific questions regarding the influence of race on jury …
Race In The Courtroom: Perceptions Of Guilt And Dispositional Attributions, Samuel R. Sommers, Phoebe C. Ellsworth
Race In The Courtroom: Perceptions Of Guilt And Dispositional Attributions, Samuel R. Sommers, Phoebe C. Ellsworth
Articles
The present studies compare the judgments of White and Black mock jurors in interracial trials. In Study 1, the defendant’s race did not influence White college students’ decisions but Black students demonstrated ingroup/outgroup bias in their guilt ratings and attributions for the defendant’s behavior. The aversive nature of modern racism suggests that Whites are motivated to appear nonprejudiced when racial issues are salient; therefore, the race salience of a trial summary was manipulated and given to noncollege students in Study 2. Once again, the defendant’s race did not influence Whites when racial issues were salient. But in the non-race-salient version …
Sticks And Stones, Phoebe C. Ellsworth
Sticks And Stones, Phoebe C. Ellsworth
Articles
I believe that research should be refuted by research. More and more of our scarce journal space is being taken up by attacks, rebuttals, and rebuttals to the rebuttals, often ending with a whimper of recognition that the adversaries were not so very far apart to begin with, and that the only way (if possible) to resolve the disagreement is through empirical research. Communication of scientific disagreement does not require a published article. Grant proposals and manuscripts submitted to refereed journals like this one are sent out to reviewers, who provide written evaluations that are communicated to the author. Papers …

Real Jurors' Understanding Of The Law In Real Cases, Alan Reifman, Spencer M. Gusick, Phoebe C. Ellsworth
Real Jurors' Understanding Of The Law In Real Cases, Alan Reifman, Spencer M. Gusick, Phoebe C. Ellsworth
Articles
A survey of 224 Michigan citizens called for jury duty over a 2-month period was conducted to assess the jurors' comprehension of the law they had been given in the judges' instructions. Citizens who served as jurors were compared with a base line of those who were called for duty but not selected to serve, and with those who served on different kinds of cases. Consistent with previous studies of mock jurors, this study found that actual jurors understand fewer than half of the instructions they receive at trial. Subjects who received judges' instructions performed significantly better than uninstructed subjects …
Are Individuals Bayesian Decision Makers?, W. Kip Viscusi
Are Individuals Bayesian Decision Makers?, W. Kip Viscusi
Vanderbilt Law School Faculty Publications
There has been increasing interest in whether normative models of individual choice under uncertainty accord with actual behavior. These concerns have been much greater than in other economic contexts because of the particularly severe demands such decisions place on the rationality of the decision maker. The limitations of these decisions have widespread consequences, as they provide the rationale for many governmental efforts to regulate the risks people face. Here I explore the issues raised by a Bayesian decision framework, focusing particularly on my analyses of worker and consumer behavior.
