by Ken Lopez No trial presentation exhibit specialist can perform any better than his or her tools. Although the judge and jury aren’t usually aware of what software the trial consultant is using, the choice of presentation software is essential to the success of the consultant, and ultimately to the success of the case. Over the last decade, presenting demonstrative evidence has usually meant using PowerPoint. In the hands of an expert trial consultant, PowerPoint is an extremely flexible tool. As we said earlier this year, for talented information designers, PowerPoint is a blank canvas that can be filled with works of presentation art. Among major law firms, PowerPoint still maintains nearly a 100 percent market share. After all, if something has been shown to work over and over again, there is every reason for a trial lawyer to continue using it rather than trying something new and unproven.
In trial presentation graphics, a great deal can depend on the quantity of data that is presented to the jury and on the way in which it is presented. For example, it has become conventional wisdom that humans generate pollution in the form of carbon dioxide, that carbon dioxide and other pollutants cause a greenhouse effect on the planet, and that this effect noticeably raises global temperatures and/or causes climate change. Al Gore's movie, An Inconvenient Truth, cemented this belief in the minds of the public and future jurors, largely through the use of effective visual presentations. The U.S. Government chart below captures the conventional wisdom well. As large quantities of carbon dioxide entered the atmosphere with rapid industrialization in the past 100 years or so, global temperatures went up, it shows.
Timelines can be extremely helpful in many types of trials. Whenever the order in which events occurred is a significant issue, or a jury or judge needs to understand how a story began and ended, a timeline is appropriate. As Texas attorney and legal technology expert Jeffrey S. Lisson has written [pdf], “Timelines are the most effective way to give a judge or jury a sense of who did what, when, and to whom. Just as bar charts and graphs help the uninitiated make sense out of a sea of facts and figures, timelines show the relationship between events. Timelines generally show events laid out on a horizontal, constant chronological scale. Events – the writing of a memo, the reading of an x-ray, or the shooting of a gun – are listed in the order they occurred. While tables of dates and facts require effort to understand, timelines are instantly clear.”
