What Does a Jury Consultant Do? Mock Trials, Focus Groups, Voir Dire, and Trial Strategy

A jury consultant helps a litigation team understand how prospective jurors may receive the evidence, identify case-presentation risks, prepare witnesses, develop voir dire strategy, and convert research into clearer trial decisions. The consultant’s role is analytical and advisory. Counsel retains responsibility for legal strategy, evidence, ethics, and the final presentation of the case.

What a jury consultant does before trial

Case and theme assessment

The consultant reviews the principal claims, defenses, witnesses, exhibits, and damages theories to identify the decisions jurors will actually be asked to make. This process often reveals gaps between the legal theory and the narrative a non-lawyer can understand. The result should be a working theme structure, not a collection of slogans.

Legal focus groups

A legal focus group is usually exploratory. Participants react to selected facts, witnesses, concepts, documents, or competing explanations. Moderated discussion helps the trial team learn how jurors describe the dispute in their own words, where they become confused, what they distrust, and which missing facts they expect to hear.

Mock trials

A mock trial is typically more structured. Participants receive adversarial presentations, evaluate disputed issues, and deliberate. The design may test liability, causation, damages, witness credibility, burden allocation, verdict questions, or the interaction among several issues. A mock trial is not a guarantee or a mechanical prediction of the verdict; it is a controlled way to identify decision pathways and risk.

Jury research and juror-profile development

Research findings can identify attitudes, experiences, and reasoning patterns that may matter in the case. A useful juror profile describes relevant risk and receptivity factors without reducing jurors to stereotypes. Demographics alone rarely explain decision-making. The stronger analysis connects attitudes and life experience to the specific issues in the litigation.

Voir dire strategy

The consultant can help translate research findings into clear, non-argumentative voir dire topics and follow-up questions. The objective is to identify bias, hardship, relevant experience, and the ability to apply the court’s instructions—not to manipulate jurors or obtain commitments about the verdict. The final scope and wording must comply with the governing court’s procedures and counsel’s ethical obligations.

Witness preparation

Witness preparation focuses on comprehension, credibility, and disciplined communication. The consultant may identify answers that sound evasive, technical explanations that lose the audience, nonverbal behavior that distracts from substance, and phrases that unintentionally concede the opponent’s theme. Preparation should improve truthful communication, not alter testimony.

Trial graphics and demonstrative testing

Timelines, medical illustrations, document callouts, animations, damages models, and comparison graphics should be tested for comprehension and fairness. A visually polished exhibit can still fail if jurors do not understand its purpose, cannot read it at courtroom distance, or perceive it as advocacy without evidentiary support. Research can show which graphics clarify and which create resistance.

Jury selection and trial support

During jury selection, a consultant may organize questionnaire responses, lawful public-source research, voir dire observations, and case-specific risk factors so counsel can make informed decisions under time pressure. During trial, the consultant may monitor juror engagement, witness performance, theme consistency, and the effectiveness of exhibits and presentation technology. No consultant can know a juror’s private thoughts, and observations should be recorded as indicators rather than facts.

Common deliverables

• A case-theme and decision-driver analysis.

• A focus-group or mock-trial research plan and participant-screening criteria.

• A written findings report separating observations, interpretations, recommendations, and limitations.

• A juror-risk framework and voir dire question set.

• Witness-specific preparation notes and communication recommendations.

• A demonstrative-evidence and trial-presentation plan.

• A prioritized list of factual, evidentiary, and narrative issues requiring further work.

Questions jury consulting can help answer

• Which facts do jurors treat as decisive, and which do they disregard?

• Where does the case become confusing or appear incomplete?

• Which witness is trusted, and what behavior drives that judgment?

• What language do jurors naturally use to describe the dispute?

• Which damages arguments appear principled, inflated, inadequate, or disconnected from the evidence?

• What alternative explanation does the opposing side have that the trial team has underestimated?

• Which voir dire topics are likely to reveal case-specific bias?

• Which graphics materially improve comprehension?

What a jury consultant should not do

• Guarantee a verdict or claim to predict individual jurors with certainty.

• Replace counsel’s legal judgment or decide admissibility and ethical questions.

• Treat a small qualitative group as a statistically representative survey.

• Suppress negative findings because they conflict with the retaining party’s preferred theory.

• Use unlawful, deceptive, or improper contact with jurors or prospective jurors.

• Prepare a witness to change facts or testimony.

How to evaluate the quality of the work

Quality is visible in the analytical record. The consultant should define the question, explain the method, preserve contradictory evidence, identify limitations, and connect recommendations to observed reactions. The most useful consultant is willing to explain why a favored theme failed and what evidence would be required to repair it.

The appropriate scope depends on the case. A focused diagnostic session may be more useful than a large mock trial when the team is still identifying the central problem; a structured mock trial may be appropriate when the record and presentations are mature enough to test as an integrated whole.
