Professor’s book looks at science behind jury verdicts

A psychology professor at Indiana University-Purdue University Indianapolis has written a book using, in part, scientific research to form a new theory as to how juries reach decisions.

Dennis Devine’s book, “Jury Decision Making: The State of the Science,” takes a look at two levels of decision making – the individual juror and the jury as a whole. In his integrative theory, Devine explores the “director’s cut” model for individual jurors, in which jurors create an “edited” version of the facts of each case based on what is the most satisfying and plausible. The jury, on the other hand, utilizes a “story sampling” model, in which jurors enter deliberations with their personal stories and then share them with each other. Other jurors, the individual’s participation in the deliberation discussion, and the personal characteristics of the juror influence the final narrative from which a verdict is made, according to a news release on the new book.

Devine looked at published studies on juries since the 1950s, which have produced various models about the jury process, including the story model and social decision scheme model. The story model proposes that jurors base their decision or verdict on a chronological narrative they create from the evidence. These stories often vary across jurors because of their different backgrounds. The social decision scheme model examines the influence of initial jury votes on how people are swayed to join the majority opinion, the release says.

“Currently, there are some real disconnects between the legal system and the scientific research,” Devine said. “Attorneys value precedent and rationale. This book comes from a scholarly perspective, where we attempt to learn something from the systematic collection of data and use it to better understand this process and improve it in the future.”

  1. Justice has finally been served. So glad that Dr. Ley can finally sleep peacefully at night knowing the truth has finally come to the surface.

  2. While this right is guaranteed by our Constitution, it has in recent years been hampered by insurance companies, i.e.; the practice of the plaintiff's own insurance company intervening in an action and filing a lien against any proceeds paid to their insured. In essence, causing an additional financial hurdle for a plaintiff to overcome at trial in terms of overall award. In a very real sense an injured party in exercise of their right to trial by jury may be the only party in a cause that would end up with zero compensation.

  3. Why in the world would someone need a person to correct a transcript when a realtime court reporter could provide them with a transcript (rough draft) immediately?

  4. This article proved very enlightening. Right ahead of sitting the LSAT for the first time, I felt a sense of relief that a score of 141 was admitted to an Indiana Law School and did well under unique circumstances. While my GPA is currently 3.91 I fear standardized testing and hope that I too will get a good enough grade for acceptance here at home. Thanks so much for this informative post.

  5. No, Ron Drake is not running against incumbent Larry Bucshon. That’s totally wrong; and destructively misleading to say anything like that. All political candidates, including me in the 8th district, are facing voters, not incumbents. You should not firewall away any of voters’ options. We need them all now more than ever. Right? Y’all have for decades given the Ds and Rs free 24/7/365 coverage of taxpayer-supported promotion at the expense of all alternatives. That’s plenty of head-start, money-in-the-pocket advantage for parties and people that don’t need any more free immunities, powers, privileges and money denied all others. Now it’s time to play fair and let voters know that there are, in fact, options. Much, much better, and not-corrupt options. Liberty or Bust!
