Lawmakers who can supply themself with information to manage complex problems are at an advantage, but equally important is the filtering and contextualizing of applicable information. Members of Congress manage a deluge of policy and political information, and this short paper examines one strategy members of Congress use to mitigate that burden—by investing in reference material and news media to filter and summarize the policymaking environment. Using congressional disbursement data from the 116th and 117th Congress, I explain how institutional experience is associated with an office's choice to invest in more information filtering. Freshman members of the House are more likely to turn to news media or publications to provide insight into the congressional agenda, offer political context, and prioritize issues of importance. Reference investment is not tied to partisanship, ideology, lawmaking capacity, or previous office, but those junior offices who need to get up to lawmaking speed invest in external information filtering. These results illuminate how central institutional knowledge is to lawmaking in Congress, and how much an office is willing to invest to mitigate that weakness.
