Current Research Priorities

Can simple, scaleable nudges shift consumption toward plant-based options?

Our lab has designed and evaluated numerous choice architecture interventions intended to promote plant-based dining, such as catering defaults and adjusting portion sizes. However, a recent meta-analysis we conducted found that many nudges are not evaluated in a way that allows for credible assessment of long-term impacts. To remedy this, we are working with partner organizations such as Menus of Change, Greener by Default, and Building Impact Through Eaters to pioneer innovative measurement strategies as part of our ongoing search for the most effective, scalable interventions.

How does introducing plant-based alternatives in real-world settings affect meat consumption?

We have several ongoing projects devoted to assessing the dietary impacts of plant-based meat substitutes. In settings such as online ordering, an empanadas chain in California, and at thirty restaurants across the United States, we are investigating where and when new plant-based items have a viable market, and if so, whether demand displaces animal-based products or substitutes for other plant-based options.

Can educational materials shift consumption?

Documentaries like The Game Changers and books like The Omnivore’s Dilemma are compelling and memorable for many people. But does exposure to these kinds of media actually shift consumption in the long term? We study these questions rigorously using meta-analysis, onlineexperiments, and observational studies in real-world settings.
