What is ES Partners?

ES Partners is a behavioral science and analytics firm.

We solve human problems.


Most problems — legal problems, employee problems, marketing problems, public relations problems — are human problems. But people are complicated. And surprising. Often quite baffling.

Data itself – and the powerful tools available for analysis – don’t automatically produce insight. It’s worthless if the analyst is blinkered or the input is garbage.

It’s hard to get more people to do what you need them to do.


Our methods uncover what really works, and reveal hidden risks and opportunities.

We combine randomized-controlled trials, Monte Carlo simulations, machine learning algorithms, and big data in project-specific, methodological recipes to predict the outcomes of anything from marketing campaigns to crisis comms and personal injury trials.

It helps to see an example. So take a look at our legal analytics and Trial Outcome Simulator for a taste of what we deliver.

And for case studies from other areas, please get in touch.


We apply our knowledge of behavioral science — from evolutionary psychology, behavioral economics, marketing, and political behavior — and data science to your human problem. We blend data science and behavioral research to produce more than the sum of their parts.

We’re more than just a method (or two, or three, or four). We know a lot about humans — and how they behave — after observing so many and running so many experiments for other clients. Humans — your customers and employees, your jurors, your audience, your (temporary) problem.

Let us help you solve your human problem today.

Adam Schaeffer

Adam Schaeffer is managing partner of ES Partners. Adam is consumed by an itch to understand what makes people tick – why they think and do the things they do. And, perhaps more importantly, how to change what they think and do.

He has a wide-range of interests and experience — he’s intensively studied evolutionary psychology, behavioral economics, marketing, policy, and political behavior. Adam has had more than fourteen years of research experience, including eleven years applying this knowledge to solve problems for clients.

In brief, he’s a behavioral scientist. Adam likes to solve human problems – whether it’s getting more people to support a policy, buy a certain energy drink, or change their preferred baby formula.

Adam received his PhD from the University of Virginia in political psychology. His dissertation assessed how different combinations of school choice policies and messages can expand and mobilize elite and mass support. He received his M.A. in Social Science from the University of Chicago, where his thesis integrated aspects of evolutionary theory and psychology with political theory and strategy. His academic research and teaching centered around social psychology and human behavior, and this emphasis continues to animate his applied research.

Alexander Oliver

Alex is a partner at ES Partners. He tends to be a bit preoccupied — the others might say borderline obsessed — with precision and details: from the exotic ink in his fountain pen to managing public opinion during wars and natural disasters. Over the last seven years in both academic and private sector contexts, he’s executed survey and field experiments to gain global strategic insights about how people think and act during crises—from political campaigns to combat missions abroad—and how to respond to them.

Alex co-authored the definitive review article on the politics of disaster relief for the forthcoming Emerging Trends project, which New York Times bestselling author and neuroscientist Daniel J. Levitin has called “an indispensable reference work for the 21st century” and the director of the Harvard Institute for Quantitative Social Science Gary King has called an “unconventional guide to the future.” He’s held faculty positions at Brandeis University and Boston University where he taught both undergraduate and graduate courses in the use of force abroad, public opinion, voter behavior, congressional behavior, and campaign strategy.

His research has been presented at both national and international conferences. Alex received his PhD from Boston University in quantitative methods and public opinion. He received his MA in economics from Tufts University, where he received the department’s most prestigious endowed scholarship, and his BA in mathematics and economics from Merrimack College.
