Confirmation bias refers to when people accept or reject evidence based upon what they want to believe as opposed to basing it on the actual merits of the evidence. In some ways, it is a psychological survival mechanism tied to our beliefs about how the world works. Challenges to these beliefs can cause a great deal of chaos and stress, so our brains are, essentially, pre-programmed to seek out evidence that reinforces those beliefs, while minimizing, explaining away, or outright rejecting evidence that challenges them. In fact, this explains the siloed media we have today where people tend to pick which news channels to watch based upon their political affiliation.
For lawyers, confirmation bias can be a significant problem at trial, especially when the first impressions favor the other party. As Nobel prize-winning psychologist Daniel Kahneman notes, “The sequence in which we observe characteristics of a person is often determined by chance. Sequence matters, however, because the halo effect increases the weight of first impressions, sometimes to the point that subsequent information is mostly wasted.” In other words, first impressions at trial often shape how jurors perceive the subsequent evidence and testimony at trial. A poor first impression of the defendant will likely lead jurors to place greater focus and emphasis on evidence and testimony that reinforces the negative view of the defendant and vice versa.

I had a very interesting experience recently on a case in New York. While we had worked with the client before, we had never worked with this particular group of attorneys. The stakes were significant and there were ongoing discussions about a potential mock trial. These discussions created an interesting dynamic where the client wanted to do a mock trial, but the client’s attorneys did not support the idea and questioned the value of such a project. Notably, the client, who we had worked with several times in the past, had never conducted a mock trial before, so while he was convinced that there was value to a mock trial, he could not necessarily articulate what the specific benefits of conducting one would be.
The end result was that the client made the decision to move forward despite his attorneys’ lack of interest. Afterwards, he was so impressed with the critical insights that we learned that the decision was made to conduct a second mock trial a month later in order to maximize the trial team’s intel for its strategy development and trial presentation decisions.
