We write here frequently about the importance of using visual evidence in trials and indeed in all sorts of other legal forums. But technology is not the be-all and end-all of persuasion. It is a very useful tool, but the importance of technology does not lessen the need to tell a convincing story to a jury or another decisionmaker. In fact, if courtroom technology is not deployed correctly, presenting visuals to a judge or jury can detract from one’s message rather than enhance it. In other words, figuring out who will be victorious at trial is not simply a matter of determining who is using litigation graphics and who is not. Any trial is ultimately about how each side can use its graphics to support an effective story. Technology-based graphics, therefore, should not be used to make up for the trial skills a lawyer lacks, but rather to enhance the skills he or she already possesses. The type of technological visual is another variable to consider when presenting an argument. Some research has suggested that depending on the case, different types of technology-based graphics can have different persuasive effects on the jury. For example, researchers compared a computer simulation of an air crash, an audiotape with written transcript of a cockpit voice recorder, and a speaker reading the cockpit voice recorder, and asked people to decide whether they believed there was a pilot error based on the evidence to which they had been exposed. The researchers found that jurors who were shown the computer animation believed the flight crew to be significantly less negligent that the other jurors who did not. Animations are so powerful because they can take us to places human beings cannot go. But even without animations, simple PowerPoint slides can be quite effective in advancing your narrative if done right.
