Chapter 7 scrutinizes how Congress’s internal resources impact the quantity and quality of information received by committees. Amid concerns over diminishing congressional capacity and the waning role of support agencies, the chapter explores the repercussions of downsizing initiatives – such as the elimination of the Office of Technology Assessment (OTA) – on committee information channels. Employing a difference-in-differences research design, the study reveals a stark decline in technical and scientific witnesses invited by committees heavily reliant on internally produced information post-OTA elimination. The findings underscore the critical role of robust congressional capacity in summoning research-based witnesses, emphasizing its pivotal significance in ensuring legislators’ access to vital scientific and technical insights.

This chapter argues that two Congresses coexist in Washington, DC. The partisan Congress, which receives the bulk of public and media attention, is characterized by polarization, gridlock, and partisan conflict. But there is also the collaborative Congress, in which members work together to find common ground. Chapter 1 draws on examples from media accounts, interviews with congressional staff, and a new dataset of congressional communications to illustrate what the collaborative Congress looks like in practice and introduce the central question of the book: Why do members of Congress collaborate? The discussion of collaboration is situated in the broader literature on Congress to explain why we know so little about it and why it matters. Conflict draws attention, and Congress is rife with highly visible disagreements, leaving little room for awareness of the members who are crafting policy through negotiation, compromise, and bipartisanship. But if the partisan Congress explains why Congress is broken, the collaborative Congress can help us understand why it works, improving Congress's capacity to legislate and address pressing societal problems.
