“The best way to understand something is to try to change it.”

— Kurt Lewin


Our research takes a social-psychological approach to social problems. That means we look for causes in the situation “right here and right now.” To a degree more than we think, the immediate social situation shapes our thoughts, feelings, and behaviors. Of course, situations are subjectively experienced, so each one is experienced differently by the different people in it, sometimes dramatically so. Over the past 30 years, my colleagues and I have leveraged the “power of the situation” to create timely, tailored, and targeted interventions that alleviate threats to people’s sense of self-worth and belonging in schools and workplaces, health care settings, political debates, and many other arenas. These “wise” interventions are often brief, but, under certain key conditions, they can yield large and lasting benefits, improving outcomes as varied as performance, health, learning, and well-being. The interventions turn fraught encounters across lines of difference into occasions for growth.  We refer to the science and art of creating such transformative experiences as situation-crafting.

Below are some sample publications from our lab and collaborators.
