new book seeks to promote better understanding of how the jury functions

Dr Helm’s book, How Juries Work is now published (and is available to buy here). The book integrates legal and psychological theory and research to present a comprehensive assessment of the modern criminal law jury, and of how evidence-based research can inform jury performance.

The book conceptualises the jury as a predictable legal instrument, whose operation can be understood and also altered by surrounding legal infrastructure. It suggests that, though important symbolically, the current jury system is not necessarily well designed to meet the demands of modern society, which increasingly requires evidence-based procedure that is carefully designed to achieve normative goals. Dr Helm proposes new models of how jurors and juries function in practice, informed by psychological theory and empirical research, which provide a framework to interpret and integrate the large body of existing work on jury decision-making. Drawing on this framework, she highlights the deficiencies and strengths of the jury as a legal fact-finder, providing key insights into how to minimize deficiencies and maximize strengths through trial procedure. The book concludes with a set of timely evidence-based suggestions as to how procedure surrounding trial by jury might be altered to enhance the administration of justice in the many jurisdictions where the criminal law jury is utilized.
