Measure the True Impact of Your Arguments

Lawsuits that go to trial can be tremendously expensive — more so when perceptions of the case’s strength don’t match reality.

Jury Lab™ Emotion Response technology was created to mitigate that risk, improving the chance of successful outcomes by testing jury responses before the case goes to trial.


“In many cases, wins and losses are decided in the opening statement.”

– Susan Constantine MPsy, Founder of Silent Messages and Creator of Jury Lab

Less Risk. More Reward

The Power of Science

Jury Lab is a patented emotion response software designed specifically for legal professionals.

Through analysis of the facial expressions of up to 12 mock jurors, legal teams using Jury Lab are able to test arguments, key points, opening and closing arguments, photographic and video evidence, witnesses, and more, to pre-determine how a real jury might perceive their trial strategy.

Powered by an expansive collection of millions of facial response data points, Jury Lab takes the science of emotion recognition technology proven in autism diagnosis, marketing/advertising research and sophisticated political strategies, and brings it to the legal profession.

So rather than the risk of assumptions, Jury Lab delivers greater clarity and certainty — which can translate into smarter settlements, adjustments in case strategy and improved chances of victory.

Why Jury Lab?

Emotions may be difficult to read, but are essential to understanding.

Created by trial consultant and human behavior expert Susan Constantine , Jury Lab is premised upon the idea that the way in which people respond to an online survey, or answer a question in a group environment, may mask their true feelings.

According to recent research , even the observations of the most astute federal judges, clinical psychologists and law enforcement professionals are right only about half the time when it comes to accurately gauging people’s emotions.

With Jury Lab in play at mock trial settings, however, attorneys can increase that accuracy by 95%.

Professionals who can benefit from Jury Lab include:

Attorneys | Trial Consultants | Research Institutions |
Academia | Government agencies | Corporations

How It Works

Jury Lab uses a series of optical arrays to track and capture dozens of separate locations on the faces of jurors during mock trials.

Every subtle facial expression, no matter how small, is measured and marked at the moment it happens.

Once gathered, digital algorithms convert all of these captured expressions into measurable, quantified inputs.

From these inputs are generated customized, easily understood reports legal teams can use to improve their arguments and strengthen their legal strategies.

Measure Emotions

Capture every smile, yawn, raised eyebrow, moment of confusion or other silent signals for conversion into actionable data.

Analyze Data

Easy-to-interpret user interfaces present all the optical sensors measured, integrated seamlessly within a framework of proven benchmarks to drive top-level analysis.

Gather Insights

See both individual and aggregate emotional engagement, plainly communicated to provide you with the information you rely on to optimize your arguments.


In February 2016, Jury Lab conducted its own market research to hear what trial attorneys had to say about mock jury simulations.

Analyzing 447 attorney responses, 59% were aware of and understood the value of mock trial consulting/focus group services, and 24% have used such services in the past. A total of 70% agreed emotions played a significant role in jurors’ decision-making process.

When asked about the advantage of receiving emotive response data (such as Jury Lab) on mock jurors’ reactions to presentations, 34% felt it would be “very significant” and 53% thought it would be “a helpful resource.”

Asked about being able to have a more complete understanding of mock jurors’ emotional reactions to witnesses, evidence, and pictures/videos during presentations, attorney responses ranged from 49%-59% saying it would be “a helpful resource,” and 22%-38% stating it would be “very significant.”

About the Founder

Susan Constantine, MPsy, author and founder of Silent Messages, developed Jury Lab to bring the proven sciences of emotion recognition, body language reading and deception detection to the legal profession at large.

Trained by Maureen O’Sullivan of Ekman Foundation and as a Humintell facial expression affiliate, Susan has become the leading expert in reading facial expressions of emotions in the legal community.

With more than 12 years’ experience analyzing jurors, witnesses, and suspects in high profile cases, Susan has been consulted as the human behavior expert for some of the world’s most noteworthy trials, including Amanda Knox, Michael Jackson, George Zimmerman, Casey Anthony, Jerry Sandusky, Bill Cosby, and hundreds of others. Additionally, she has provided insights and analysis during media coverage of the past three (3) US presidential elections.

Susan has appeared on CNN, FOX, ABC, CBS, and MSNBC, and been published in the Washington Post, Capitol Hill, New York Times, and the New York Post.

Professionally, she has trained FBI and Homeland Security agents, The Department of Defense Inspector General, The Federal Court Judicial Law Judges and attorneys in hundreds of private law firms.

She further provides CLE training in over 30 states in the US, teaching government agencies and legal professionals how to read facial expressions, emotions, and body language, and how to detect deception and emotional/cognitive processing.

“Training thousands of attorneys and government agencies how to read facial expressions of emotions and to detect deception has always been a rewarding career — but it’s a combination of art and science, not acquired overnight.

With Jury Lab, my clients have a technology that allows us to read the relevant data points of the face linked to human emotion, and translate the interpretations into information that can be used to improve case strategies.”
