Congressional hearings, including legislative, oversight, investigative, and confirmation hearings, are key public moments where Members of Congress, committees, and their staff gather and process the information they need to make informed decisions about complex legislative and oversight topics. In addition to public hearings, Members and staff also engage in informal briefings and conduct other forms of research and meetings. However, the procedural rules and design of congressional hearings and other existing opportunities for fact-finding may not be optimized to promote the effective and efficient transfer and use of evidence. The challenge is frequently compounded by the complexity of scientific jargon and lack of training for researchers on how to communicate with policymakers. Further, simply adding to the evidence base or improving the diversity of participation does not solve the problem that committees’ and Members’ staff lack the time needed to process evidence. This conversation will focus on strategies to enable more effective use of evidence in hearings and other legislative processes.
