Asking the right questions during voir dire is important in determining bias. Being prepared for voir dire makes a difference in correctly removing a potentially negative juror. Scientific jury selection with rigorous research to test hypotheses is preferred. With a sufficient number of mock jurors, predictors that differentiate jurors who favor plaintiffs from those who favor defendants generally surface. Secondarily, understanding body language and observing jurors’ reactions to questions is critical. We also educate on Batson and Wheeler challenges.
