Berkman Center logoSciences Po logo A team of researchers at the Berkman Center for Internet & Society at Harvard University and Sciences Po Paris, led by Professor Yann Algan and Wikimania 2011 keynote speaker Professor Yochai Benkler, invites English Wikipedia contributors to participate in an interactive online experiment on decision making. The goal of this study is to better understand the dynamics of interactions and behavior in online social spaces. The project has been reviewed by the Wikimedia Research Committee and extensively discussed on the English Wikipedia Administrators’ noticeboard. The Wikimedia Foundation is happy to support this project which we believe will help advance research on our community.

Starting today, logged-in eligible editors will receive an invitation to participate in this study via a CentralNotice banner. To reduce banner overload, the invitation banner has been coded so as to be displayed only to a sample of English Wikipedia contributors meeting eligibility conditions for this study. If you are among the editors selected for this study, please consider participating. If you disable the banner, it will not be displayed to you anymore.

The survey takes about 25 minutes to complete. It combines a series of interactive experiments on decision making with questions about attitudes and practices. Based on their decisions and those of other participants in the study, participants will earn money that they can then choose to donate to the International Committee of the Red Cross or the Wikimedia Foundation if they so wish.

The data collected by this study is subject to European privacy protection protocols and will be used for research purposes only. All research outputs and data, while preserving full anonymity of participants, will be made available under an open access license. The research team will present its findings at a Wikimania conference.
