Bill Kanasky, Jr., Ph.D. and Ava Hernandez join host Steve Wood, Ph.D. for another edition of From the Trenches where they discuss recent observations and updates from jury research projects, witness trainings, and cases that the CSI team have been working on. First, they talk about how too many attorneys wait until close to trial to contact the CSI team for help with training witnesses for trial and/or jury research, or even jury selection, and the problems with waiting until the eve of trial to bring in help. They discuss the more appropriate timing to prepare witnesses for trial and why starting early is important, particularly with emotional or challenging witnesses, because of the significant time it takes for behavior change. Next, they talk about the pitfalls of having the witness's spouse present during their testimony and why the spouse should not be involved in a witness's deposition preparation nor in the courtroom. Ava shares how defense attorneys should prepare for aggressive plaintiff counsel questioning of emotional witnesses and how the training for these emotional witnesses needs to be handled during preparation. The team also discuss use of interpreters and how some witnesses for whom English is a second language sometimes request an interpreter for their deposition, however, they are fluent enough that an interpreter is not needed and actually creates a credibility issue. Lastly, the group talk about how the qualifications of an expert witness do not always translate to a strong performance during testimony.
