Sandra Matz is the David W. Zalaznick Associate Professor of Business at Columbia Business School, in New York, where she also serves as the Director of the Center for Advanced Technology and Human Performance.

As a computational social scientist with a background in psychology and computer science, Sandra studies human behavior and preferences using a combination of big data analytics and traditional experimental methods. Her research, and the topic of this podcast, uncovers the hidden relationships between our digital lives and our psychology with the goal of helping businesses and individuals make better and more ethical decisions.

We dive into some fascinating insights from her January 2025 book, MINDMASTERS: The Data-Driven Science of Predicting and Changing Human Behavior, exploring the concept she coined of “psychological targeting,” a discipline that reveals how our digital footprints expose intimate aspects of our psychology and can be used to shape decisions—from what we buy to how we vote.

In this podcast, we delve into this topic, discussing:

How digital technologies and AI are giving us unprecedented abilities to understand and target specific people in specific states
The profound implications, for better or worse, of this capability
Some exciting—and concerning—examples of what this might look like, from diagnosing mental health to crafting highly-personalized automated marketing campaigns
How this hyper-personalization and new AI has the potential to influence, change and even control our behaviors
What companies can learn from Apple’s “Evil Steve” test in designing products and experiences to safeguard future ethical misuse of data
A glimpse into what could be a solution to the ethical dilemma of the capabilities Sandra studies: federated learning—a new form of data modeling that protects the individual’s data while delivering high-quality insights
