3. Jury Persuasion

About this Lecture

Lecture

In this lecture, we think about jury persuasion by witness and defendant characteristics, focusing in particular on: (i) strategies used by legal professionals to influence jury decisions; (ii) three important models of persuasion, starting with Hovland and Janis’ 1959 Yale Model of Persuasion; (iii) the four key elements of this model being source, message, recipient, and situation; (iv) the two further models of persuasion as storytelling and rhetorical strategy.

Course

In this course, Professor Ciaran O’Keeffe walks through two vital parts of the legal system process – evidence collection and courtroom psychology. In the first lecture, we think about the range of biases that can arise in the collection and processing of forensic evidence. In the second lecture, we focus on fingerprint analysis as a type of forensic evidence. In the third lecture, we move on from forensic evidence and begin to explore techniques of jury persuasion, targeting three key models of persuasion. Next, three defendant characteristics which can impact jury decisions of guilt or innocence are outlined: regional accents, race, and crime type. In the fifth lecture, we continue this discussion, broadening to characteristics of gender, age, and attractiveness. In the sixth and final lecture, Professor O’Keeffe brings to light an issue which has been documented back to the mid nineteenth century, but presents itself as increasingly important in the modern age of internet access – pre-trial publicity.
