RSF will accept letters of inquiry (LOIs) under these core programs and special initiatives: Social, Political and Economic Inequality; Future of Work; Behavioral Economics; and Decision Making and Human Behavior in Context. In addition, RSF will also accept LOIs relevant to any of its core programs that address at least one of the following issues:

• Research on the Covid-19 pandemic and the resulting recession in the U.S. Specifically, research that assesses the social, political, economic, and psychological causes and consequences of the pandemic, especially its effects on marginalized individuals and groups and on trust in government and other institutions. Our priorities do not include analyses of health outcomes or health behaviors. RSF seldom supports studies  focused on outcomes such as educational processes or curricular issues, but does prioritize analyses of inequities in educational attainment or student performance. 
• Research focused on systemic racial inequality and/or the recent mass protests in the U.S. Specifically, research that investigates the prevalence of racial disparities in policing and criminal justice and their social, political, economic, and psychological causes and consequences; the effects of the current social protest movement and mass mobilization against systemic discrimination; the nature of public attitudes and public policies regarding policing, criminal justice, and social welfare; and the effects of those attitudes in the current political environment.

LOIs must include specific information about the proposed data and research design. After peer review, about 15% of those who submit an LOI will receive an invitation to submit a proposal.
