Which everyday products secretly switched to AI sorting first, and could people opt out?

"listeners experienced these algorithmic and recommendation features as impersonal in determining their background listening, music discovery, and playlist curation."

"As of 2011, Facebook has stopped using the EdgeRank system and uses a machine learning algorithm that, as of 2013, takes more than 100,000 factors into account."

"While listener desire for more control over recommendation settings is not new"

"uses a machine learning algorithm that, as of 2013, takes more than 100,000 factors into account."

"Some of the methods that Facebook uses to adjust the parameters are proprietary and not available to the public."

"they are, however, commonly opaque and users have no insight into which goals an algorithmic system optimizes exactly"

"but that users also often find themselves at a loss, are unaware of the content selection logic (Hsu et al. 2020), and that even placebo control instruments may increase user satisfaction (Vaccaro et al. 2018)."

"it has been argued that the possibility of altering performance-relevant parameters of the ADM system would allow users to customize how decisions are made for them"

"we investigate how Twitter's switch from a reverse-chronological timeline to algorithmic content selection in March 2016 influenced user engagement with tweets published by German newspapers."

"In 2018, Facebook overhauled its News Feed algorithm, implementing a new algorithm which favored " Meaningful Social Interactions " or "MSI". The new algorithm increased the weight of reshared material—a move which aimed to "reverse the decline in comments and encourage more original posting"."

"For example, X (formerly Twitter) moved away from a chronological feed toward an AI-powered ranking system that personalises content for each user."

"We find that the number of likes increased by 20% and the number of retweets by 15% within a span of 30 days after the switch."

"The Washington Post reported that for three years, Facebook's algorithms promoted posts receiving the new reactions (including the "angry" reaction) from its users; giving them a score five times that of traditional likes."

"For example, Facebook's news feed is designed to surface content aligned with users' prior engagement, which may reinforce existing views."

"Importantly, our results indicate a rich-get-richer effect, implying that initially more popular outlets and news topics benefited the most."

"According to The Wall Street Journal , documents show that in 2019, Facebook reduced the time spent by human reviewers on hate-speech complaints, shifting towards a stronger dependence on their artificial intelligence systems to regulate the matter."

"Users may further narrow their feeds by actively blocking certain content or accounts."

"User engagement also increased more for sensationalist content than quality news stories."

"Internal engineers and researchers within Facebook have estimated that their AI has only been able to detect and remove 0.6% of "all content that violated Facebook's policies against violence and incitement"."

"Personalized search may also allow users to explicitly filter results by blocking content containing certain phrases or hashtags."

"Clegg also claimed that Facebook allows users to override their algorithm to take more control."

"Facebook introduced its News Feed in 2006. In a 2016 company explanation, Facebook said that stories were ranked so users saw material it predicted they cared about first."

"Cards are based on what Google expects you to be interested in at the moment."

"Social media platforms must notify new and existing users over 16 and offer a clear choice for their default feed. They can opt in to personalized algorithmic recommendations. Or they can opt out and see only posts from friends and creators they deliberately follow."

"The plan to force platforms to notify users of their ability to “opt out” is a fresh concept, but the underlying right to assert control over a feed is not. European social media users have had that option since 2023."

"A feed can be ordered by time, with the newest post at the top. Algorithmic systems order it by prediction instead. They score each post by how likely a particular user is to watch it, click on it, or reply to it, and by how long that user is likely to stay with it."

"Users can also tell Google when they are not interested in certain topics to avoid seeing future updates."

"Digital services including online games, apps, AI chatbots and search engines would face new obligations to protect users, especially minors, from addictive design features and specific categories of harmful material."

"Every citizen would get an off-switch for the algorithms that hypnotise them for hours each day."

"The 1992 Tapestry mail system and the 1994 GroupLens news filtering system were early milestones before recommendation systems spread into e-commerce and other online services."

"Google Search query results have been shown by Internet activist Eli Pariser to be tailored to users"

"Legislation is slated for introduction to Parliament before the end of 2026."

"On background, it argued there was no single algorithm that can be turned off, and that a broad switch would strip out critical ranking and safety functions."

"In 2013, Google significantly upgraded its search algorithm with "Hummingbird"."
