Elizabeth L.

Behavioral Designer and Founder, DTA Innovation

United States


Elizabeth Long is a behavioral scientist and designer with a focus on global health and development with 20 years of expertise. While working on implementing or evaluating programs she realized that so many of the programs were not designed around the way people actually think, instead they were designed around an unrealistic ideal of human decision-making, leading to suboptimal programs for participants and funders. Elizabeth loves challenging myths about the fact that information interventions (posters, radio skits, etc.) alone change behavior. Knowledge matters, but how, when and by whom it is transmitted and the receiver’s context are frequently overlooked in program design. Behavioral economics shows that we as humans don’t always see or process information. And even if we form an intention, that may not lead to action. Her methodology focuses on the contextual factors that influence cognitive and behavioral biases and how using these contextual cues to design interventions lead to better outcomes. She also focuses on building empathy in systems by challenging the idea that if someone doesn’t do a behavior it’s because they “don’t understand the benefits” or “aren’t motivated” and need to just be provided more information. In addition to managing projects that identify biases and codesign solutions to them, she also works with organizations to teach them how to follow the process on their own: how to incorporate applied behavioral economics and human-centered design tools into their existing methodologies to strengthen their own internal capacity.
