Recommendation algorithms that customize information feeds for individuals have raised concerns about exacerbating inequalities in news exposure among citizens. In response to these concerns, we conducted an audit study on YouTube analyze the algorithmic impact curating versus other content topics. We examined over 1.7 million video recommendations audited 2019 and developed novel analysis approaches including network Markov chains. Results show recommendation may potentially redirect users...

Recommender systems not only serve users but also affect user preferences through personalized recommendations. Recent researches investigate the effects of entire recommender system on preferences, i.e., system-level effects, and find that recommendations may lead to problems such as echo chambers filter bubbles. To properly alleviate problems, it is necessary estimate recommending a specific item item-level effects. For example, by understanding whether an aggravates chambers, we can...

In today’s high-choice media environment, some scholars are concerned that people selectively consume content based on personal interests and avoid others, which might lead to audience fragmentation across different genres. Individually, there be trade-offs between those genres, especially entertainment versus news. This study analyzed a large user engagement dataset (~40,000 users’ comments) collected from the Chinese information application Toutiao, one of most popular distribution...

Healthy news consumption requires limited exposure to unreliable content and ideological diversity in the sources consumed. There are two challenges this normative expectation: prevalence of online; prominence misinformation within individual diets. Here, we assess these using an observational panel tracking browsing behavior N ≈ 140,000 individuals United States for 12 months (January–December 2018). Our results show that panelists who exposed consume more reliable from a ideologically...

While partisan selective exposure could drive audience fragmentation, other individual factors might also differentiate news diets. This study applies a method that disentangles the differential contributions of characteristics to duplication networks. By analyzing nationally representative survey about US adults’ media use in 2019 ( N = 12,043), we demonstrate fragmentation is driven by myriad factors, such as gender, race, and religiosity. Partisanship still an important driver. We...
