A recent study sheds light on the increasing use of scientific research by members of Congress and their staffers in crafting legislation. However, the analysis reveals a stark partisan divide in the selection of research sources, potentially hindering bipartisan collaboration and policy effectiveness.
Published on the preprint database SocArXiv, the study examined over 49,000 committee documents from both the Senate and House of Representatives between 1995 and 2021. It found a significant rise in citations to technical papers over the years, with a sixfold increase observed by 2020. Yet, committees led by Democrats were nearly twice as likely to cite scientific papers compared to their Republican-led counterparts.
Furthermore, the study revealed that Democrats and Republicans often cited different papers, with only a small fraction receiving references from both sides. This ideological discrepancy persisted across various scientific fields and policy issues, even within documents addressing the same topic.
Notably, committees under Democratic control tended to cite recent, peer-reviewed papers that were widely acknowledged in the scientific community. Conversely, those led by Republicans were less inclined to reference such sources.
Similar disparities were observed in reports published by U.S. think tanks aligned with either liberal or conservative ideologies. This trend suggests a broader skepticism among individuals leaning right towards scientific advice and research.
The study underscores concerns that policymakers may selectively use research to support existing beliefs rather than objectively evaluating all available evidence. Such practices could erode public trust in both government and science and lead to less effective policies.
Despite these challenges, the authors remain hopeful that bipartisan-cited scientific literature could serve as a basis for promoting mutual understanding and collaboration in a politically polarized climate. Improved awareness of shared scientific evidence may offer new avenues for constructive dialogue and policy development among lawmakers.
