The author argues that scientists must better advocate for federal funding of basic scientific research by directly engaging with members of Congress. As a former congressional science fellow, the author observed similarities between the scientific process and policymaking process. Scientists are encouraged to explain their passion for their work and the importance of funding to elected officials through briefings, visits to congressional offices, and personal stories that resonate more than technical details. Personal advocacy from a diversity of scientists, especially early career researchers, can influence policymakers' decisions around science budgets.
