Participatory research increasingly seeks tangible outcomes contributing to social transformation. We reflexively examine the role of affect in two participatory research projects in Colombia to argue that intentionally making space for and reflecting on affective experiences can help generate more effective research. Such ‘praxis of affect’ focused on building social bonds, demonstrating solidarity, distributing expertise, and sharing hope were critical for sustaining motivation toward the research endeavor and social transformation efforts. This article contributes to literature on participatory research by considering ways to implement socially-responsible research that creates momentarily affective spaces and recasts the desire for more durable outcomes in such spaces.
