Much of the scientific research in the United States is conducted in the public interest and funded through tax dollars, with exact funding allocations controlled through a variety of high-level processes, including through legislation. Scientists can provide expert opinions to government officials and their staff in this and other processes of establishing and enforcing governmental legislation, policies, and regulations, although such expertise is often underutilized. This is partly due to the paucity of scientists who have training to engage policymakers.To address this deficit, many scientific societies now provide organized training in science policy, including how to seek out opportunities to engage with policymakers. One such example is the Entomological Society of America's Science Policy Fellowship (ESA SPF) program. This article is written by ESA SPF members and discusses the importance of interfacing with policymakers, some challenges this group encountered, and lessons learned through our experiences in the program. Through efforts like this, we hope to inspire other scientists to engage their societies in advocacy work and make their voice heard.
