Combining Common Knowledge with Specialized Expertise
Expert testimony is required when the determination of standard of care or causation is beyond the ordinary experience and knowledge of the normal fact finder. But jurors are also instructed that they may use their own common knowledge and life experience to decide the case. In effect, our justice system seems to be talking out of both sides of its mouth: we bring experts to teach jurors the most complex aspects of our case, but jurors are ultimately free to use their own experience and common sense to decide it. Which means that either both will come together for a verdict in your favor, or they will compete with one another and your outcome is less certain.
Credibility Counts
Beyond the legal requirements for expert qualification (which is serious business, but truly unrelated to the ultimate question of how persuasive an expert will be) it’s important to evaluate expert witnesses the same way you size up any other witness.
I assess all witnesses along three general components of credibility: trustworthiness, competence and likability. Each of these are characterized by a wide variety of traits, only some of which are shown below:
Trustworthiness |
Competence |
Likability |
Dependable, Reliable, Consistent, Honest, etc. |
Skill, Knowledge, Training, Reputation, Experience… |
Warmth, Manners, Humor, Listening Skills, Empathy… |
Most experts score off the charts in competence.[i] But be sure you are evaluating your potential experts on the other two elements of credibility from the time you first meet them. Keep a checklist in each expert witness file so you will remember to deliberately evaluate your witness along all three dimensions. Do this every time you meet with your expert. It only takes a few minutes and you can track what you are noticing over time, while there is still time to help the witness communicate more effectively or to make changes to your line-up for trial if necessary.
It is easy for lawyers themselves to fall into “expert” mode when talking with experts, but if you do so you may be over-emphasizing the value of competence, or short-changing the importance of trustworthiness and likability. If your choice is between the expert with humor and humility and the one with a much longer list of publications on a CV – and you are sure that both will be qualified as experts and help you overcome a Daubert challenge or motion for summary judgment – choose the one jurors will like and trust the most.
Finally, make the majority of your calls with experts by videoconference. Skype™ is free and witnesses can take their computers or tablets wherever they go; there are no good excuses for not doing so anymore and no call is too short. Take your own video camera (or your iPad™) to your initial interview with experts and record your conversations. While you’re talking literature and technical details, the video camera will capture the other components of credibility. Once back at your office, you can review the videotape and record your observations separate and apart from the substance of your discussion.
The Mechanics Matter: Experts Are People Too
Your experts will communicate their important (and expensive) testimony by the same means all other human beings communicate, so you should also be evaluating them for both verbal and non-verbal skills. Jurors’ impressions and opinions will be based on everything they see and hear from an expert on the stand (or by video), not just the impressive curriculum vitae.
Just as you can rate your experts on components of credibility, you can also rate them on a wide variety of traits within categories of verbal and non-verbal communication, such as:
Voice |
Speech |
Non-Verbal |
Volume, rate, pitch, pace… |
Memory, vocabulary, interaction with opposing counsel, teaching skills… |
Eye contact, posture, gestures, mannerisms… |
As you make your observations, share them with your expert as you go. Be sure to compliment on things done well, and deliver constructive feedback on the things that are getting in the way of overall credibility.
If you feel awkward giving this kind of specific feedback to an expert, it may be a sign that you don’t have the rapport you will need to work well with that expert in front of a jury, or it may signal that you have an arrogant expert on your hands. As an experienced trial consultant, I’ve often been charged with giving feedback to expert witnesses. In my experience, most expert witnesses are grateful for the attention to detail because they value their own reputation and want to do well in every case.
If you are concerned about rules governing disclosure of your work with an expert witness and how it can be done with a trial consultant present in the prep session, be sure to review your local rules and read up on the issue[ii]. You can also send a video of your working session with a witness and allow the trial consultant to provide you with feedback that you can then pass along to your expert.
Finally, do not assume that because you have picked an expert with a lot of experience testifying in other cases that any other lawyer has done this preparation work for you. In fact, I recommend starting with an expert in the same place I would with any other witness: using a series of open-ended questions that are not specific to expertise.
Some of these include:
- What are your strengths as a witness? What are your weaknesses?
- If you have testified in jury trials before, did you get any feedback from jurors about how you did? If so, what did you learn?
- What do you have to say that will help the case?
- What do you have to say that will hurt the case?
- What do you understand your role in the case to be? How does it compare to other witnesses, if you know?
- What do you believe to be the important theme(s) in the case?
- What do you most want the jury to know about you? What do you most want the jury to know about the case?
I am often surprised at how infrequently attorneys ask simple “getting to know you” questions of their experts. Remember that jurors themselves are experts in their chosen professions and experts are ordinary people too when they are not at work. Questions like those above have the effect of opening up and “normalizing” your super-experts, which makes them far more relatable to jurors at trial. Remember the components of credibility include the qualities of witnesses that make them likable and trustworthy. You will have to look for and encourage those traits or an expert will default to competency every time.
You may also be surprised to learn that some experts have no clue whatsoever how their specific testimony relates to your overall strategy for the case, have never considered how expert testimony compares to the testimony of other witnesses, or have no idea what your working case themes are. No witnesses (expert or otherwise) are going to be effective until you have helped them to internalize these ideas and incorporate them into testimony.
Give Your Expert a Stake in the Outcome
To deepen experts’ commitment to your case, introduce them to your clients. If you can’t do so directly, use pictures and videos wherever possible to enhance the deposition transcripts your experts review. The most effective expert witnesses I have ever seen are those who feel a direct (if not also personal) connection to your case and your clients. If you find that an expert is not really that interested in knowing much about your clients, you have a good clue that the expert will fail on at least one major component of credibility (likability).
Beyond forming an emotional or psychological connection to your clients, your experts may be in a better position strategically to help you fight off contributory/comparative fault claims if they know – and understand – how and why your clients behaved the way they did. If your experts are not showing enough interest, prompt them with questions like these:
- What are you most curious about in this case?
- If you could ask my client anything, what would you ask?
- Have you ever known anyone (or a company) like my client who was in a situation like this before? What does it bring to mind?
- What do you most want the jury to know about how you think or feel about my client?
Experts who genuinely care about your client will use language in their testimony that reflects this. Listen for – and encourage – all the ways that your experts can give opinions that also convey care and concern for the individual (or anyone in a similar situation), rather than impersonal, general statements of a rule or standard.
At Trial: Arm Your Experts with Jurors’ Own Experiences
After you have done the front-end work to prepare an expert to be effective in deposition and with a jury, you also have an opportunity to gather more information at trial that will be useful to the expert once on the stand.
If you plan your questions carefully, jurors will tell you about their expectations for expert testimony during voir dire without you ever mentioning the phrase “expert testimony.” Good jury selection techniques allow us to get jurors thinking about what they already know that will be important to – and consistent with – our expert testimony. The very best questions enable you to marry the “common” with the specialized knowledge.
From work experience alone – in any case, with every juror – you can start to establish what qualities make an expert credible. Obviously you want to encourage and positively reinforce answers that identify those traits you wish to highlight in your own expert:
- Are you qualified in your profession by: Your degree? Your training? Your experience?
- Tell us about each of those and which you hold most valuable or important in your work.
- Are there technical aspects of your job?
- Do you consider yourself an expert at what you do? Why do you think so? What did it take to become an expert?
- When you do not agree with other experts on the job, how do you resolve those differences?
- If you were wrong about something on the job, would it be difficult for you to admit it? On the other hand, if you felt sure you were right are you willing to stick to your guns?
You can also get jurors talking about the very ideas you want to advance through your witnesses and test jurors’ willingness to accept and adopt the opinions of an outside expert.
- Are you required to comply with safety rules or standards where you work?
- Are you bound by any professional standards in your practice?
- On a scale of 1 to 10, how would you rate the importance of the rules and standards in your work? Why are they important in your job (or not)?
- Are those rules or standards handed down by outside experts or are they unique to your place of work?
- How often – if ever – do you seek the opinion of outside experts who may be able to see your situation at work more objectively and bring good ideas to the table?
Lastly, an expert witness will be prepared to tell jurors how and why the defendant either did or did not fall below the standard of care and caused (or didn’t cause) the Plantiff’s harms and losses. Hopefully your experts’ opinions will match those pre-existing ideas jurors bring with them to the jury box, and to ensure this, you will need to ask jurors to tell you, for example:
- What makes a good doctor good?
- What makes a bad doctor bad?
- What’s the difference between an accident and negligence?
- What’s the difference between medical mistake and malpractice?
After you have gathered jurors’ own ideas, beliefs and opinions on these and other important issues, talk to your experts and share those insights so that they can strike the same note when they take the stand. Having an expert put testimony in terms that are familiar to jurors gives your expert a huge advantage over a “smarty-pants” who doesn’t know the importance of paying attention to the sensibilities of the jury.
The time and money you invest in expert witnesses is perhaps the greatest expense of any case. No matter how impressive the credentials, experts must relate as well to jurors as their testimony must relate to the facts and law. If you are not already tending to the expert’s strengths and weaknesses that are distinct from technical expertise and specialized knowledge, you may be inviting jurors to substitute their common knowledge, life experience, or common sense for the testimony of an ineffective – but not inexpensive – expert witness.

Giving your expert a stake in the outcome is probably one of the worst ideas I’ve ever heard. I have been instructing expert witness class is in the real estate appraisal field for over 25 years and have personally testified over 200 times.
First and foremost, the expert should remain, and appear to the jury to be unbiased and someone that would testify the same regardless of who they were hired by. The expert witness should be an advocate for their own opinion only. It is the attorney’s job to be an advocate for the client.
In my opinion it is not important if the expert likes or even knows the client. The expert’s opinion is based on a set of facts and data as analyzed and interpreted by the expert and should never change based on personal likes or dislikes of the client.
Attorneys are paying expert witnesses to the tune of $350 to $650 an hour for case material review, consulting and deposition testimony. Fees for testimony at trial are often $5,000 a day plus expenses, or more. It seems to me that experts today already have a LOT of stake in their cases and jurors know it.
That said, I understand the point being made: objectivity in an expert matters. I don’t disagree. If you are hired solely to explain the laws of physics for a products liability case or the appraisal value of a property in a given market, you might not need to be curious about the client who is paying you to testify.
On the other hand, experts who testify about the future life care needs of a spastic quadriplegic who choose objectivity over real time spent with the injured plaintiff will most certainly lose credibility on the stand. And the engineering expert in my sidebar example not only didn’t care about the impression he made of himself by being snide and snarky, he may have been ruining it for the client who paid him hundreds of dollars an hour to give the deposition.
I stand by the questions I recommend experts ask the attorney to become invested in the important role they play in a case. The specific application of expertise to a unique set of facts is far more persuasive than abstract theory alone. Experts who don’t care whether the side they testify for wins or loses won’t usually get the opportunity to testify hundreds of times in their careers. Attorneys like to bet on the horse that wins.
Jurors today know every expert’s own financial “stake” in the case down to the penny. What I am suggesting is that experts also take a genuine interest in getting to know the parties they are paid so handsomely to help.
I agree that a jury wants experts to offer unbiased testimony, and an expert must appear (and I use the word ‘appear’ purposefully) unbiased to jurors. I disagree, however, that the appearance of a lack of bias means that an expert cannot show sympathy to a client or that he/she likes the client. I believe these are separate issues, and the most persuasive experts appear unbiased to jurors AND show sympathy/concern/liking for a client.
In my experience, experts who seek to appear unbiased using a detached/”distancing” style tend to appeal only to the rational/logical decision-making side of jurors, while experts who provide an unbiased opinion and simultaneously are sympathetic to a client appeal to jurors’ rational/logical AND emotional sides — and, in my experience, jurors find these “unbiased and sympathetic” experts more persuasive.
Juror decision-making is not only based on logic and facts, and an expert addressing the emotional side of jurors’ decision-making in addition to their logical side is helpful to a client. I am not recommending the expert become an advocate; just that the expert relay an opinion that shows concern/liking/sympathy for the client, which can be directly attributable to the expert’s independent review of the facts.
I believe that an expert can be independent in decision-making and come to respect/like/etc. a client, and their opinion remain unbiased if the liking/respect arises *out of* making the evaluation, rather than the liking/respect preceding the evaluation. Jurors find persuasive an expert who conveys that (a) he/she did not previously know the client, (b) he/she reviewed the materials, and (c) he/she gained an appreciation/liking/etc. for the client during (because of) that review. The issue is what comes first, the review or the liking? As long as the evaluation comes first, an expert’s liking of a client aids the client tremendously, I believe, and the showing of that respect/liking /sympathy helps in ways that a “cold hard statement of the facts” simply cannot.
I also want fully to support the author’s point that experts are more persuasive if they also focus on conveying trustworthiness and likability to jurors. Persuasion research has long established that credibility hinges on multiple criteria in addition to competence. I believe the evidence is clear that anyone (be it expert, attorney, everyday person) who focuses only on competence, shortchanges his/her ability to persuade and shortchanges his/her clients.
Perhaps the wording in the article of “giving your expert a stake” is a bit problematic, and might be reworded to “have an expert demonstrate sympathy, concern and/or liking for the client arising out of the evaluation conducted”. The initial wording can suggest that an expert should be “sided” and “advocate” for the client like an attorney, even though I don’t believe that is the author’s point. For me, the takeaway from this article is to have an expert be unbiased in his/her opinion *and* to relay that opinion in a manner that show the sympathy, liking and concern for the client that arose in the making of that opinion; and I strongly support that.

For a more empirically-informed approach to these issues, see our research:
Brodsky, S.L., Griffin, M.P., & Cramer, R.J. (2010). The Witness Credibility Scale: An outcome measure for expert witness research. Behavioral Science & the Law, 28, 892-907.
Cramer, R.J., Neal, T.M.S. DeCoster, J., & Brodsky, S.L. (2010). Witness Self-Efficacy: Development and validation of the construct. Behavioral Sciences & the Law, 28, 784-800.
These issues are important, and we adopt an empirically-informed approach in our practice. I hope such future articles will account for the knowledge we have on these issues from both research and practice experience.
Thanks Robert. We really focus here at The Jury Expert on doing both theory and practice. We asked Charli to write an article on practice approaches but her experience is very much informed by empirical research. If you would like to write an article more focused on lessons from research, we would be happy to review it. There is value in both. And, in fact, we always ask for specific practice recommendations from theory-based pieces so the information is directly relevant to the practitioner. –Rita
Robert, it’s not clear which part of my article you find at odds with empirical research so I don’t know if I have a reply that you will consider worthy of your comment. I got my graduate degree in Litigation Science and have worked with attorneys and their witnesses for almost 20 years. I feel rooted in theory and steeped in experience.
The expert (quoted) who wasn’t well-prepared to give his deposition did not need more research, he needed practical help and feedback; which he got, before testifying at the trial where my client’s client was awarded $10 million.
Last week I attempted a post-verdict interview with a juror who asked me how much she would be compensated for the interview, “considering how much all those experts in the trial were paid.”
I just keep going where my practical experiences take me. I will look forward to reading your empirically-based article on the topic in a future issue of The Jury Expert.
Hi folks — Let me clarify that it isn’t necessarily that any part of the practice-based piece that is at odds with research. It is actually nice to see that such ideas are at play in the field. Trial consulting based on theory and practice is great; the piece I am encouraging to add is making overt utility of the admittedly limited amount of empirical data in the field. Translational research that can (hopefully) bridge the gap between evidence-based practice and experience is definitely needed. Perhaps this idea is fodder for a future article?
