This article examines how social capital affects the resolution of disputes by focusing on English Wikipedia’s Arbitration Committee, sometimes described as “Wikipedia’s Supreme Court.” Drawing on quantitative and qualitative data, the article contends that the Arbitration Committee not only examines the merits of the claims made by the disputants, but also and more crucially considers the position of each disputant within the community of editors in its decision-making process. In doing so, the Arbitration Committee does not simply decide or arbitrate disputes but seeks to attenuate their impact on Wikipedia’s social fabric. This data allows us to revisit sociological debates on the role of social capital, by revealing the ways in which well-connected individuals employ it strategically in order to obfuscate their noncompliance with norms, thus leading to what I call “dispute cancellation.”
