Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir Jan 2012

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 Jan 2011

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 Jan 2011

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 …


The Case For Behaviorally Informed Regulation, Michael S. Barr, Sendhil Mullainathan, Eldar Shafir Jan 2009

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 Jan 2008

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, …


Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth Jan 2003

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 Jan 2003

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 Jan 2000

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 Jan 1999

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 Jan 1992

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 …
