School of Business and Management Department of Economics 200 Understanding and De-biasing User Media Consumption Supervisor: LU Yang / ECON Co-Supervisor: David HAGMANN / MGMT Student: CHUN Yeji / OM HUANG Liangshuang / ECOF MA Chenxuan / MAEC Course: UROP 1000, Summer UROP 1100, Summer UROP 3200, Summer Media bias and public opinion jointly shape how people understand social, economic, and political issues. However, traditional approaches often measure them separately and just assign simple labels to media articles by their sources. But the real-world opinions are much more nuanced, and people interact with media in ways that reflect subtle ideological differences. Therefore, our goal is to develop a scalable method that jointly measures article stances and user positions on a single, continuous ideological spectrum. In other words, we place both articles and people on the same axis so that comparisons are direct and meaningful. And this summer, we mainly focus on checking: conditional on ideological bin, whether A- and B-users evaluate every C-article almost identically, whether the two subsamples are well aligned.
