As social scientists set out to investigate public policy questions, it is vital that they take into account the history of issues and the way people\u2019s emotions will shape interpretations and responses to research findings. That\u2019s the message that Mathematica\u2019s Matt Stagner hopes to convey in his presidential address at a fall research conference hosted by the Association for Public Policy Analysis & Management (APPAM) in Denver. \n\nOn the Evidence interviewed Stagner about his upcoming address, his work on child welfare, and his reflections on the field of public policy research. This interview is part of a series of episodes produced by Mathematica in support of the APPAM conference in November.\n\nA Q&A blog featuring highlights from the conversation is also available on the Mathematica website: https://.mathematica-mpr.com/commentary/embracing-the-emotional-aspects-of-public-policy-research
