YouTube users have no control over the management of the videos offered by the platform according to their activity, because not only are the mechanisms it offers inefficient, but bad recommendations appear over time, according to the latest Mozilla research. Foundation.

Site Recommendation Algorithm YouTube’s recommendation algorithm uses a user’s previous activity to suggest other videos related to their interests, but the results it sometimes delivers have generated controversy and research trying to understand how it works.

One of the opponents of this algorithm was the voice of the developer Guillaume Chalot, one of the engineers responsible for its programming, who in 2019 mentioned its ability to . takes viewers time.

YouTube, on the other hand, has upheld its role in the fight against misinformation by improving the algorithm over time to prioritize authoritative content over hoaxes and conspiracy theories.

The company says that users can manage recommendations based on their activity on YouTube, Chrome, and Google through specific actions such as. remove some videos from play history and search history, pause those stories or delete them directly.

Another possibility offered to the user is to indicate in the video even if it matches. the topic he / she was looking for o if you are not interested, but also with the Like or Dislike buttons. These are the actions the Mozilla Foundation took into account in its latest study, in which it analyzed, these are effective options for managing the recommender algorithm.

Based on an activity sample of 22,722 volunteers, 2,758 respondents, and 567,880,195 videos, the conclusion of the Mozilla study is this. people have no control over what is shown in YouTube recommendations.

In line with what they called bad advice. Compared to the control group, which received 39% of bad recommendations, users who used the Like button received 35%, the same percentage as those who indicated they were not interested.

Those who chose to remove videos from their story received 28% of bad recommendations, and users who checked the “Don’t recommend this channel” box reduced their occurrence to 22%.

For effectiveness, the Mozilla Foundation points out in their research that the option is “Don’t recommend this channel to me.” seems to prevent the most bad recommendations (43%), followed by deleting game history (29%), while “Not interested” (11%) and “Like” (12%) seem to be the least effective.

Another finding from the study is that bad recommendations appear over time despite YouTube’s various recommendation management mechanisms.

He also believes that he should “improve his data access tools.”
