TikTok disproportionately served anti-Democratic videos during the 2024 election

Summary

A recent study provides evidence that TikTok’s recommendation system tends to expose users to more conservative and anti-Democrat political content than liberal material. This ideological imbalance occurs regardless of a user’s initial political interests, suggesting that automation plays a significant role in modern information access. The research was published in the scientific journal Nature. Researchers at New York University Abu Dhabi’s AI and Society Lab conducted the new research to explore how automated internet systems shape what political news the public sees. Experts debate whether internet polarization is driven by people seeking out their own preferred viewpoints or by computer algorithms pushing extreme content to keep users engaged. Corresponding author Talal Rahwan noted the difficulty of answering this question on older platforms. “Our previous work studied recommendation algorithms on YouTube, and a persistent challenge was disentangling algorithmic influence from user self-selection,” he told PsyPost. TikTok offers a helpful environment for testing algorithmic influence because its primary interface relies heavily on automation. “TikTok’s For You page, where the algorithm drives nearly everything users see, offered a uniquely clean setting to study that question, especially with the 2024 election making political content on the platform increasingly consequential,” Rahwan added. To gather data, the researchers created 323 automated bot accounts to act as artificial users, a method sometimes called a sock puppet audit. Between April 30 and November 11, 2024, the scientists launched 21 new accounts each week. Each bot was assigned an age between 22 and 24 to mimic the habits of young adult voters. The research team used location-masking software to virtually place these phones in specific parts of the country. They assigned the bots to New York to represent a reliably Democratic area, Texas to represent a reliably Republican area, and Georgia to ac...
