Incorporating Social Science Into Criminal Defense Practice, Eve Brensike Primus Nov 2020

Incorporating Social Science Into Criminal Defense Practice, Eve Brensike Primus

Articles

In recent decades, social scientists have created a treasure trove of empirical and sociological data that defenders can and should use to help their clients. Evidence rules, criminal law, and criminal procedure are filled with concepts informed by social science. When is evidence likely to unfairly prejudice a defendant in the eyes of a jury? Do police interact differently with members of minority populations and how should that inform concepts of reasonableness? How easy or difficult is it for people to identify individuals they see during high-stress criminal episodes? How effective are police interrogation tactics at getting at the truth …


Implicit Bias In Daily Perceptions And Legal Judgments, Keith B. Maddox, Samuel R. Sommers Jan 2017

Implicit Bias In Daily Perceptions And Legal Judgments, Keith B. Maddox, Samuel R. Sommers

University of Michigan Journal of Law Reform

In today’s demonstration, we explored the audience’s positive and negative associations with blacks and whites. The demonstration is an adaptation of the Implicit Association Test (www.projectimplicit.net), a computer-based task designed to explore mental connections between various concepts. Participants were presented with a list of concepts (stereotypically black and white names, pleasant and unpleasant concepts) in a column down the middle of a screen along with the response categories (black/white or Pleasant/Unpleasant) along the left and right sides. When reading a word, participants were asked to categorize it by slapping the knee (left or right) that corresponds to the category displayed …


The Cognitive Psychology Of Circumstantial Evidence, Kevin Jon Heller Nov 2006

The Cognitive Psychology Of Circumstantial Evidence, Kevin Jon Heller

Michigan Law Review

Empirical research indicates that jurors routinely undervalue circumstantial evidence (DNA, fingerprints, and the like) and overvalue direct evidence (eyewitness identifications and confessions) when making verdict choices, even though false-conviction statistics indicate that the former is normally more probative and more reliable than the latter The traditional explanation of this paradox, based on the probability-threshold model of jury decision-making, is that jurors simply do not understand circumstantial evidence and thus routinely underestimate its effect on the objective probability of the defendant's guilt. That may be true in some situations, but it fails to account for what is known in cognitive psychology …


Apology Within A Moral Dialectic: A Reply To Professor Robbennolt, Lee Taft Jan 2005

Apology Within A Moral Dialectic: A Reply To Professor Robbennolt, Lee Taft

Michigan Law Review

Over the last several years, much has been written about the role of apology in facilitating the resolution of legal disputes. Within this body of work a debate has developed among legal scholars, practitioners, and legislators. Under traditional rules of evidence an apology which acknowledged fault would enter evidence as an admission against interest. Now there is a movement to legislatively "protect" apologies from the effects of the traditional rule in order to facilitate apology without evidentiary encumbrance. Scholars who have argued in favor of the relaxation of the traditional rule have largely relied on anecdotal evidence to support their …


E' Is For Eclectic: Multiple Perspectives On Evidence (Symposium: New Perspectives On Evidence), Richard D. Friedman Jan 2001

E' Is For Eclectic: Multiple Perspectives On Evidence (Symposium: New Perspectives On Evidence), Richard D. Friedman

Articles

A conference titled "New Perspectives on Evidence: Experts, Empirical Study and Economics" has a pronounced alliterative theme, a theme made even more apparent when, inevitably in evidentiary discourse, epistemological questions come to the fore. It is enough to make one suspect that the conference is secretly brought to you by the letter "E," hiding behind its public front, the Olin Foundation. Putting aside such conspiratorial thoughts, all these "E's" suggest the presence of a meta-"E"-Eclecticism. Indeed, I believe this conference has demonstrated the need for an eclectic approach to evidentiary problems. That should be no surprise. The domain of evidentiary …


Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth Jan 1993

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, …
