<p>Policy and political learning are often critical for addressing complex and pressing policy issues, such as housing policy, which has implications for human wellbeing, social equity, and environmental sustainability. This paper explores the extent to which different types of policy and political learning occur, by whom and when in the context of a 2023 housing policy debate in Colorado. We selected a comprehensive omnibus housing bill that, raised intense debates, was amended, and ultimately failed to pass. In this study, using novel methodology, we examine policy and political learning of different actors as evidenced by changes in policy beliefs over different phases in the bill’s legislative process as expressed in the news media. We find that some actors—primarily legislators—show signs of policy learning by shifting their policy positions throughout the bill’s process. After the bill failed to pass, actors expressed more political learning, proposing new strategies for the next legislative session. While prior research on learning in policy processes finds that policy actors tend to reinforce their own beliefs, evidence from this study indicates that actors may engage in learning throughout the legislative process, particularly around political beliefs. By exploring what is learned, who learns, and when they learn around proposed housing legislation, this study offers novel theoretical and empirical insights into the scholarship on learning in policy processes.</p>
