Project description

Are individual biases mirrored in collaborative web contents? For instance, is the Ukraine presented in a systematically more favorable light than Russia in the Ukrainian Wikipedia article about the Crimean Crisis and is Russia favored in the Russian Wikipedia article about the Crimean Crisis? If biases such as this in-group bias are contained in online encyclopedias as well, these biases could shape the view of a broad audience.


However, prior research with individuals on biases cannot be generalized to online-encyclopedias because it does not take factors and processes into account that are relevant in the context of collaborative production of web contents.


The junior project group “Collaborative Biases” systematically focuses on three aspects and investigates their effect on biases in collaboratively produced web contents: (1) the specific norms that exist in the collaborative environment and which guide authors’ contributions, (2) the process of audience tuning (i.e., an author’s tuning of his or her contribution to the expected opinion of other authors or the readership), and (3) the pervasiveness of the bias. The project comprises highly ecological field studies (e.g., comparisons of various online encyclopedias; comparisons of users’ contributions to different language versions of the same article, such as the Russian vs. Ukrainian article about the Crimean Crisis) as well as highly controlled and thus internally valid lab experiments.
