Public Engagement with Science calls for scientists to think more reflexively about their research, and how assumptions, power and contexts influence associated communication. To interrogate this, we utilised design to stimulate reflexive thinking about science communication through a residential ‘Engagement Incubator’ that took the form of a pop-up cardboard laundromat. Participants reported an increased appreciation for, and insight into, PES theory, and its relevance to their work. In addition, our experience of enacting PES theory, and reflexive thematic analysis of data collected through the process, deepened our own understanding of PES and reinforced our appreciation of engagement as reproductive, and inherently circular work.
