Understanding the role of a jury is important to winning a case. It's key to recognize how the jury will perceive you, the case and its surroundings. It's important to understand how the jury will take facts or alleged facts and weigh them against other information in your case.
When a jury is chosen, your attorney and the other party's attorney will take steps to make sure it's as unbiased as possible. This helps the jury start fresh with no perceptions that could influence your case. Even determining that there is no social bias won't necessarily take away bias against your physical appearance or attitude, though, so that's why it's important to come to court looking clean cut and presentable.
What should you do to appear better to the jury?
Treating the judge and jury with respect also helps your case. Here's an example. If you come into court and greet the judge with respect and dignity, the jury will witness this. That is your first impression, and one that is vital to your case. If you instead come into the court looking disheveled and are rude to the judge, the jury may see you as unprepared, disrespectful and negative. Casting yourself in that light is not good for your case.
Another thing that you have to prepare for is the jury's memory and decision-making process. You should take the time to focus on reminding the jury of important points that help your case while downplaying allegations that hurt you. The jury is more likely to remember those facts and to use them heavily in debate when they deliberate privately.
Recognize that the jury must come to a group decision, so watching how the jury responds during the trial can help you adjust the way you approach the case. By being perceptive, you and your attorney can make good choices as you move forward.
