How are people’s private lives influenced by doing paid social-justice work? How do private interests influence organizational efforts to advance equity? This project is a multiparadigmatic examination of “organized prosociality” (work intended to benefit others), especially of the roles played by private interests therein. My past research has identified micro-level mechanisms linking employees’ private interests and prosocial work, drawing upon original, longitudinal ethnographic engagements across two distinct work settings—grantmaking and international aid. At this juncture, I am eagerly poised to push the boundaries of my scholarly engagement into more interdisciplinary terrain, leveraging conceptualizations of public and private boundaries from across the humanities alongside empirical findings on prosociality from the social and biological sciences. This project grew out of an IAS 5x5 group that I spearheaded on prosociality, inspiring and emboldening me to study this question in a sustained, interdisciplinary way. I aim to craft a radical re-envisioning of organized prosociality that interrogates and effectively theorizes the nuanced roles played by private interests.
