A recent study by researchers at the University of Arkansas and the Center for Information Technology Innovation has revealed that YouTube’s algorithm may be subtly steering users away from political content on its Shorts platform.
The study, which analyzed over 685,000 YouTube Shorts videos, investigated how the platform’s recommendation system adapts based on viewing time and the sensitivity of the content. The findings suggest that YouTube actively begins recommending entertainment videos to users who spend a significant amount of time watching political content within Shorts.
Mert Jan Chakmak, one of the study’s authors, explained, “When you start [watching] specific political topics, YouTube tries to push you towards entertaining videos, funnier videos, especially in YouTube Shorts.”
To conduct their research, Chakmak and his team initially collected approximately 2,800 videos across three categories: the 2024 Taiwan election, the South China Sea conflict, and a broader “general” category. They then tested how the recommendation system responded to three different viewing durations: 3 seconds, 15 seconds, and watching the video in its entirety. The researchers observed 50 consecutive recommendation transitions. The results consistently showed that regardless of the initial topic or viewing duration, political content was gradually replaced by entertainment content.
The full study, which is available on the Cornell University arXiv preprint server, involved analyzing 685,842 short videos. The titles and transcripts of these videos were classified by topic, relevance, and emotional tone using the OpenAI GPT‑4o model.
The study also found that the algorithm tended to favor videos with a positive or neutral emotional tone. Furthermore, high-performing shorts with a greater number of likes and views were disproportionately promoted, reinforcing a bias towards popularity.
Chakmak noted that most users are likely unaware of this algorithmic behavior, stating, “Maybe some people know about it, but I’m sure most people don’t realize what the algorithm does. They just go and watch.”
Neither YouTube nor its parent company, Google, have issued a statement regarding the study’s findings.
However, Chakmak believes that this shift in recommendations is not necessarily intentional censorship. Instead, he suggests it is a strategy to maximize user engagement and revenue, particularly given that even YouTube Premium Lite subscribers are shown ads on short videos.
“YouTube is trying to take you out of that area or topic and push you to a more interesting topic so that it can increase engagement and bring in more money,” Chakmak said.
YouTube Shorts, which was launched in 2020 to compete with TikTok, features vertical videos that are up to 60 seconds long. As of January 2022, Shorts had amassed over 5 trillion views. Studies have also shown that users spend more than 1% of their waking hours watching YouTube Shorts, with these short videos receiving approximately 200 billion views each day.
The study comes amid earlier reports of YouTube expanding its video player, hiding the “Trends” page, and implementing stricter monetization requirements, which could potentially impact the earnings of AI content creators on the platform.
