Predicting the trial value or settlement value of a personal injury case with precision is very difficult because there are so many factors that can affect the value of a case. The jury decides how much money to award you for your injuries and accordingly, different juries will arrive at different verdicts under the same set of circumstances. Jurors bring with them their own personal biases that can either help or hurt you. Accordingly, this unpredictability leads to a wide range of results. So for settlement purposes, the personal injury lawyers and insurance companies take an average of what they believe a jury would award. If they generally agree on what that average is, the case will typically settle if the client agrees.
