Credibility of an expert witness is a critical factor at trial. Constructs of credibility are complex, and the Witness Credibility Model (Brodsky, 2010) breaks credibility down into the following components: Trustworthiness, Knowledge, Confidence, Likability.
Confidence has received a lot of attention in the expert witness world, with higher degrees of expert witness confidence originally thought to result in higher degrees of expert witness credibility. However, this turns out to be not quite true. It has been shown that while a low degree of expert witness confidence correlated with lower credibility, and a medium degree of expert witness confidence correlated with higher credibility... a high degree of expert witness confidence then led to a lower degree of credibility (Cramer, 2009). So higher and higher degrees of confidence go from the credible expert witness to the cocky expert witness.
On the other hand, trustworthiness and knowledge have been shown to be positively correlated to credibility. Majority of expert witnesses are knowledgeable... they are the experts. This cannot be changed by the attorney. Trustworthiness, however, is a different animal than knowledge. The trustworthy expert is the one who is most objective. An expert that comes across as the most objective will win the trustworthiness battle.
Cleareview provides your expert witness with the platform (Blind Expert Review) or data (Blind Panel Review) to provide an objective, and hence trustworthy, opinion.
