Some content changed, but opinions showed no consistent change
Nearly 9,000 US adults used a YouTube-like platform with altered recommendations, and researchers measured their political attitudes.
The study, in plain language
A recommendation can influence which video appears next, but you choose which one to open. To explore this process, the team built a platform resembling YouTube with real videos and manipulated its suggestions. In three experiments, people chose what to watch. In the fourth, they viewed assigned sequences.
Changing recommendations altered some choices in the experiments where participants could choose. Political attitudes, however, showed no consistent change across the short-term tests. The clearest difference was in some of the content people watched, without a recurring change in opinions across experiments.
The key idea
Altered recommendations changed some video choices. Brief exposure produced no consistent change in political opinions.
Something to think about
When choosing videos in a feed, separate two questions: what content is shown to you, and whether it changes what you think. This experiment measured only brief exposure.
