Our experience in jury selection activities in a wide range of matters in venues across the country has led us to the conclusion that three juror characteristics – Empathy and Emotional Responsiveness, Cognitive Ability and Motivation, and Psychological Locus of Control – act as perceptual filters that influence judgments make about the issues in your case. We have codified our knowledge of these factors into A Theory of Jury Selection that forms the conceptual foundation for our recommendations regarding voir dire themes and jury selection.
