Crowdsourcing not all sourced by the crowd: An observation on the behavior of Wikipedia participants

•Wikipedia articles are not always rightly sourced from the crowd.•Wikipedia articles are often maintained by a dominant few.•The dominance of the few participants becomes more severe as the crowd matures.•Intrinsic motivation encourages Wiki participants to engage in revising articles.

This study investigates the behavioral patterns of Wikipedia participants to obtain a picture of internal dynamics of the world's largest crowdsourcing platform. It observes the responses of people when “other” people enter a crowd where internal and external controls are mostly absent. From the analysis of 342 Wikipedia articles, this study shows that the overall tone of Wikipedia articles is mostly decided by a dominant few rather than by a trivial many, and such domination worsens as the number of participant increases and the article matures. This result contradicts a common belief on crowdsourcing that Wikipedia would reflect the voices of a vast majority, obtain a balanced solution, and attain democracy on the Internet. Therefore, this study contributes to the literature by analyzing how effectively Wikipedia functions as a crowdsourcing platform within the context. It also implies that developing a proper crowdsourcing strategy such as effective management of a platform is necessary, especially when an organization has a specific goal to achieve throughout a project.
