In 2021, in support of the US House Select Committee on the Modernization of Congress, The GovLab organized two online advisory sessions to inform the Committee’s process of developing recommendations on evidence-based lawmaking. With support from Democracy Fund and the Burnes Center for Social Change, these two conversations brought together diverse experts in evidence-based practices from a range of disciplines and fields, ranging from experts in Congressional operations and procedures, to science and research communication experts, to current and former lawmakers. The first conversation covered how Congress can exchange with researchers to provide evidentiary support around problems that Congress has already identified as priorities or to bring important problems to legislators’ attention. The second conversation focused on strategies to enable more effective use of evidence in hearings and other legislative processes.
