This document discusses various ways that researchers can inform and influence policy. It begins by outlining some established channels for submitting evidence to policymaking bodies, such as public bill committees and select committee inquiries. It then poses some questions about whether researchers should simply make their evidence available or try to more proactively target and communicate it to relevant policy teams. The rest of the document explores some pros and cons of both informing and influencing policy, and discusses some principles of effective policy influencing like understanding processes, building relationships, and reflecting on what works.
