Motivated Judicial Reasoning

Posted by The Situationist Staff on November 30, 2009

In her recent book, Law, Politics, and Perception: How Policy Preferences Influence Legal Reasoning (2009), Eileen Braman examines how policy preferences and legal authority interact to influence judicial decision making.  Here’s the book’s abstract.

Are judges’ decisions more likely to be based on personal inclinations or legal authority? The answer, Eileen Braman argues, is both. Law, Politics, and Perception brings cognitive psychology to bear on the question of the relative importance of norms of legal reasoning versus decision markers’ policy preferences in legal decision-making. While Braman acknowledges that decision makers’ attitudes—or, more precisely, their preference for policy outcomes—can play a significant role in judicial decisions, she also believes that decision-makers’ belief that they must abide by accepted rules of legal analysis significantly limits the role of preferences in their judgments. To reconcile these competing factors, Braman posits that judges engage in “motivated reasoning,” a biased process in which decision-makers are unconsciously predisposed to find legal authority that is consistent with their own preferences more convincing than those that go against them. But Braman also provides evidence that the scope of motivated reasoning is limited. Objective case facts and accepted norms of legal reasoning can often inhibit decision makers’ ability to reach conclusions consistent with their preferences.

Kevin Jon Heller on The Cognitive Psychology of Mens Rea

Posted by The Situationist Staff on July 22, 2008

Kevin Jon Heller, a law professor at the University of Auckland and contributor to the Opinio Juris blog, has recently posted on SSRN his essay “The Cognitive Psychology Mens Rea.” Below is an abstract of the essay, which can be downloaded for free at this link.

Actus non facit reum nisi mens sit rea – the act does not make a person guilty unless the mind is also guilty. Few today would disagree with the maxim; the criminal law has long since rejected the idea that causing harm should be criminal regardless of the defendant’s subjective culpability. Still, the maxim begs a critical question: can jurors accurately determine whether the defendant acted with the requisite guilty mind?

Given the centrality of mens rea to criminal responsibility, we would expect legal scholars to have provided a persuasive answer to this question. Unfortunately, nothing could be further from the truth. Most scholars simply presume that jurors can mindread accurately. And those scholars that take mindreading seriously have uniformly adopted common sense functionalism, a theory of mental-state attribution that is inconsistent with a vast amount of research into the cognitive psychology of mindreading. Common-sense functionalism assumes that a juror can accurately determine a defendant’s mental state by applying commonsense generalizations about how external circumstances, mental states, and physical behavior are causally related. Research indicates, however, that mindreading is actually a simulation-based, not theory-based, process. When a juror perceives the defendant to be similar to himself, he will mindread through projection, attributing to the defendant the mental state that he would have had in the defendant’s situation. And when the juror perceives the defendant to be dissimilar to himself, he will mindread through prototyping, inferring the defendant’s mental state from the degree of correspondence between the defendant’s act and his pre-existing conception of what the typical crime or defense of that type looks like.

This goal of this essay is to provide a comprehensive – though admittedly speculative – explanation of how jurors use projection and prototyping to make mental-state attributions in criminal cases. The first two sections explain why jurors are unlikely to use a functionalist method in a case that focuses on the defendant’s mens rea. The next three sections introduce projection and prototyping, describe the evidence that jurors actually use them to make mental-state determinations, and discuss the cognitive mechanism – perceived similarity between juror and defendant – that determines which one a juror will use in a particular case. The final two sections explain why projection and prototyping are likely to result in inaccurate mental-state determinations and discuss debiasing techniques that may make them more accurate.
