PurposeThis paper explores the often overlooked and novel academic concept of honest incompetence as a potential “dark” side of social entrepreneurship, where well-intentioned but inadequately skilled agents hinder the effectiveness and sustainability of positive social change initiatives.Design/methodology/approachWe have adopted a multiparadigm approach to theory building, known as metatriangulation. We draw upon agency theory and behavioral decision theory to undergird a framework consisting of antecedents, processes, outcomes and moderators of honest incompetence in social entrepreneurship.FindingsWe introduce a detailed framework for understanding honest incompetence in social entrepreneurship. This framework identifies antecedents such as knowledge gaps, examines mechanisms like misguided interventions and explores consequences, including group vilification. Additionally, it investigates moderating factors, emphasizing the disadvantages of outcome-based compensation and the difficulties in evaluating outcomes.Originality/valueThis article investigates factors that engender honest incompetence in social entrepreneurship, revealing how even well-intentioned efforts can inadvertently hinder goals. Despite their sincere motives, social entrepreneurs might make choices that conflict with their objectives. Addressing this issue necessitates a customized approach, which includes engaging actively with the community and fostering robust social connections.
