Effects of the “intimate conviction” instruction on the processing of judicial information

Abstract

Introduction and objectiveThe aim of this study was to examine the effects of the “intimate conviction” (IC) instruction on the processing of judicial information. The IC instruction encourages the use of impressions to form a verdict. As such, according to cognitive-experiential self-theory (CEST) (Epstein, 1994), it is more likely to (1) elicit experiential information processing, and (2) bias judgments, compared with instructions prompting the rational and objective processing of information running counter to IC (CIC). Method and resultsNinety-four mock jurors were randomly assigned to one of three experimental conditions (IC, opposite IC and control), and asked to view a video of a criminal appeal hearing, deliver judgments and perform a thought-listing task. Results confirmed that, in the IC and control conditions, participants were more likely to (1) process evidence in an experiential mode, (2) judge the defendant's acts as being more intentional than participants in the opposite IC condition. However, contrary to our expectations, the effects of the instructions on the attribution of intention were not mediated by the information processing mode. ConclusionDirections for future research and the implications of the present study for judicial systems using inquisitorial procedure are discussed.
