Interventions grounded in behavioral science can range from small “nudges” or programmatic tweaks to large policy overhauls. Alone or in combination, these interventions act as force multipliers, ratcheting up the effectiveness of any given program or initiative. While good behavioral design cannot fully offset the negative effects of structural problems like racism and economic inequality, it can help families derive maximum benefit from the resources and services available to them. The addition of behavioral science to the toolkits of poverty-fighting organizations and policy-makers across the U.S. represents a significant opportunity to create meaningful social impact.
