Bio

Sara Constantino is an assistant professor at the Stanford Doerr School of Sustainability in the Department of Environmental Social Sciences and a visiting research scholar at Princeton's School of Public and International Affairs. She is also a faculty affiliate at SPARQ and the Social Science Environmental Health Research Institute. She has an interdisciplinary background at the intersection of economics, psychology, and environmental policy and politics. Her research focuses on understanding the interplay between individual, collective, institutional and ecological factors, including how they shape preferences, decisions, experiences and resilience to extreme events or shocks. In recent and ongoing studies, she is looking at the role of polarization, social norms and governance in stimulating or stifling climate action, including both adaptation and mitigation, and what conditions lead groups mobilize to shape policy and other outcomes. She also works on the impacts and politics of guaranteed income and other cash transfer programs. Prior to starting at Stanford, she was an assistant professor in the School of Public Policy and Urban Affairs and the Department of Psychology at Northeastern University and an associate research scholar at Princeton’s School of Public and International Affairs. Before this, she was a senior research fellow in guaranteed income with the Jain Family Institute, a founding editor at Nature Human Behavior, and a research coordinator with the Institute for Fiscal Studies. She received her bachelor’s degree in economics from McGill University, a master’s degree in economics from University College London, a Ph.D. in cognitive and decision sciences from New York University, and did a postdoc focused on environmental policy, politics and decision-making at Princeton University.

  • Anticonformists catalyze societal transitions and facilitate the expression of evolving preferences. PNAS nexus Mittal, D., Constantino, S. M., Vasconcelos, V. V. 2024; 3 (8): pgae302

    Abstract

    The world is grappling with emerging, urgent, large-scale problems, such as climate change, pollution, biodiversity loss, and pandemics, which demand immediate and coordinated action. Social processes like conformity and social norms can either help maintain behaviors (e.g. cooperation in groups) or drive rapid societal change (e.g. rapid rooftop solar uptake), even without comprehensive policy measures. While the role of individual heterogeneity in such processes is well studied, there is limited work on the expression of individuals' preferences and the role of anticonformists-individuals who value acting differently from others-especially in dynamic environments. We introduce anticonformists into a game-theoretical collective decision-making framework that includes a complex network of agents with heterogeneous preferences about two alternative options. We study how anticonformists' presence changes the population's ability to express evolving personal preferences. We find that anticonformists facilitate the expression of preferences, even when they diverge from prevailing norms, breaking the "spiral of silence" whereby individuals do not act on their preferences when they believe others disapprove. Centrally placed anticonformists reduce by five-fold the number of anticonformists needed for a population to express its preferences. In dynamic environments where a previously unpopular choice becomes preferred, anticonformists catalyze social tipping and reduce the "cultural lag," even beyond the role of committed minorities-that is, individuals with a commitment to a specific cause. This research highlights the role of dissenting voices in shaping collective behavior, including their potential to catalyze the adoption of new technologies as they become favorable and to enrich democracy by facilitating the expression of views.

    Abstract

    Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.
