Train to Win workshops are the best way to train your courtroom instincts.  These 1-day mock trials utilize the most sophisticated equipment and scientific methods so you can peer into jurors' minds.  By analyzing the live graphical display of jurors' moment-to-moment reactions to Reptile and Rules of the Road techniques, Tammy Metzger will teach you what drives juror decision-making.  Learn more about these fun Train to Win CLE Workshops.

David Ball contributed his insights to Tammy's article, How Rules and Reptile Approaches Work.  This paper explains how trial advocacy techniques elicit subtle emotions that drive juror decision-making, including how jurors perceive risk, causation, blame and guilt.   (See The Jury Expert, May 2011.)
