By Dr. Ken Broda-Bahm:
You have probably noticed that the experience of watching a movie in a theater is different from the experience of watching that same movie in your home. Even with the larger home-theater screen and sound system, there is still something about seeing a great film on a truly big screen: it holds attention better, it's more involving, and it's more memorable. By nature, the theater experience accentuates, meaning that a good movie can be better and a bad movie can be worse when it is projected on the big screen. The same dynamic applies to in-court presentation. Of course, IMAX isn't coming soon to a courthouse near you, but based on new research in The Jury Expert (Heath & Grannemann, 2014), larger screen sizes in court do make a difference.
The research seems to be the first study of its kind focusing on the effect of screen and video size on mock jurors' evaluations. The conclusion is that, "An increase in the video image size heightened the effects of evidence strength." That means that, as with the movies, the good gets better and the bad gets worse. "An increase in video size resulted in strong evidence appearing stronger and weak evidence appearing weaker." The results, along with two published responses from trial graphics and technology consultants, provide some practical considerations that go beyond the question of "Will they be able to see it?" This post takes a look at the study as well as its implications for your trial setup.
