Most of modern society receives their information via visual and written media, if not exclusively visual. For some people, this extends to learning to the extent that the only way the person can learn is if they’re able to see it with their eyes. This presents a problem for the way most trials transpire. At least a few members of the jury are likely to consider themselves visual learners and will struggle to keep up with the vast amounts of complex information that’s being presented.
The best solution to this problem is to include a visual aid. Allan Barsky said in his book, Clinicians in Court:
“As noted throughout this volume, the purpose of providing evidence at a trial is to educate the judge or jury about the facts in a case. As the saying goes, “Seeing is believing,” so using visual aids in courtroom presentations can have a critical impact on the decision makers. Seeing a torn piece of clothes may be more convincing than just hearing about it.”
