Psychologists who have studied the way people communicate and learn have discovered that approximately 2/3 of the population (2/3 of any jury pool and judges) are "visual learners." That is, people tend to process new information that is presented to them in a visual format much more effectively than when the same information is presented to them verbally.
Psychologists have also determined that 2/3 of all lawyers are auditory or hearing people. That is, they tend to process information more effectively by hearing information. Furthermore, studies have also shown that people tend to communicate information, or "teach", in the same way that they prefer to learn. Therefore, most lawyers, as auditory learners, prefer to communicate information, or teach, by speaking rather than by showing.
In the typical courtroom scenario, what one finds is a jury, comprised mostly of visual learners, who are waiting to be shown the information, and lawyers, who are auditory learners and teachers, attempting to communicate the information by verbally explaining it. This common situation invariably creates a significant gap in communication between the lawyer and the judge and jury. The impact of this gap upon the success of a case cannot be overstated because if a judge or jury cannot visualize your argument, they typically will not understand it. Animators, by designing persuasive and creative courtroom evidence, helps to bridge the gap between the verbal communicator and the visual learner.
