For more than 30 years, we’ve worked with trial teams across the country, and we’ve learned something simple:
Cases improve when lawyers test their themes under real jury pressure.
What has changed is not whether mock trials work.
What has changed is how we conduct them.
Today, trial teams must decide between:
- In-person mock trials
- Online (virtual) mock trials
- Or a layered combination of both
We run both formats constantly. And when structured properly, each can deliver powerful strategic insight.
But format is not the most important decision.
Design is.
Our Gold Standard Mock Trial Methodology
When the stakes justify it, we do not run small, casual focus groups.
We recruit 80–100 jury-qualified participants.
We create a case-specific mock juror questionnaire.
We conduct a structured mock voir dire.
Then we reduce the pool to three separate 12-person panels.
- One plaintiff-leaning
- One defense-leaning
- One mixed
That segmentation is not theoretical.
It allows us to see which arguments persuade which psychological profiles.
It shows us how risk shifts across group compositions.
It tells us where your case fractures.
And we do this all the time.

In-Person Mock Trials
In-person mock trials bring jurors into a controlled research facility.
They watch presentations.
They deliberate face-to-face.
We observe everything.
Why We Use In-Person Mock Trials
1. We see the nonverbal moments.
The eye rolls. The folded arms. The hesitation before someone changes a vote.
Those moments rarely show up in surveys.
They often decide verdicts.
2. We observe authentic group pressure.
In-person deliberations create real social gravity. Strong personalities dominate. Quiet jurors align or resist.
You feel the energy shift.
3. We test physical demonstratives properly.
Large trial graphics. Physical models. Timeline boards. Exhibit binders.
Scale matters.
4. Engagement tends to be higher.
Controlled environments reduce distraction and screen fatigue.
Where In-Person Has Limitations
- Higher cost
- Longer lead times
- Geographic concentration
- Fewer iteration cycles
For late-stage, high-exposure cases, this investment often makes sense.
For early theme development, it may be more than necessary.
Online Mock Trials
Online mock trials recruit jurors through secure digital platforms.
They review case materials remotely.
They deliberate virtually.
We moderate and analyze in real time.
Why We Use Online Mock Trials
1. Speed.
We can launch in days, not weeks.
2. Iteration.
We can test competing narratives quickly. Refine. Re-test.
That agility sharpens cases dramatically.
3. Broader recruiting.
Multiple venues. Larger sample sizes. Hard-to-source demographics.
4. Cost efficiency.
Lower overhead allows more testing waves.
Where Online Has Limits
- Subtle nonverbal cues are harder to capture
- Home distractions can occur
- Physical exhibit testing is less tactile
- Deliberation dynamics can be slightly more orderly
For early and mid-stage testing, the efficiency advantage is enormous.
Side-by-Side Comparison
| Factor | In-Person Mock Trials | Online Mock Trials |
|---|---|---|
| Speed to Launch | Weeks | Days |
| Cost Structure | Higher | Lower per wave |
| Behavioral Observation | Full body language | Limited to screen |
| Deliberation Energy | High social pressure | Moderated, slightly muted |
| Juror Reach | Local venue | National / multi-venue |
| Sample Size | Smaller | Easily scalable |
| Exhibit Testing | Best for physical evidence | Best for digital evidence |
| Iteration | Slower | Rapid theme testing |
| Best Use Stage | Late-stage validation | Early to mid-stage strategy |
| Our Typical Role | Deep-dive risk assessment | Theme refinement & strategy |
What We Often Recommend: A Layered Strategy
The most sophisticated trial teams don’t choose one format.
They layer them.
- Early online testing to identify promising themes
- Iterative refinement
- In-person deep-dive before trial
That combination often produces the most confident decision-making.
This often pairs well with early-stage case theme development and storytelling refinement — especially in matters where we are also assisting with 👉 Opening Statement Strategy and Storytelling
The Real Takeaway
Online mock trials are no longer experimental.
In-person mock trials are no longer automatically required.
But disciplined design — recruiting 80–100 jurors, conducting voir dire, segmenting panels — remains the difference between surface insight and predictive insight.
When done thoughtfully, mock jury research changes outcomes.
When done casually, it creates false confidence.
We focus on the former.
