Anatomy of a scroll: Inside TikTok’s AI-powered algorithms

When Hamas attacked Israel on October 7, many people sought updates from their main source for news: social media.

But unlike previous global conflicts, where digital discourse was dominated by Facebook and X (formerly Twitter), the ongoing Middle East crisis has seen people flock to TikTok by the millions to connect with news and express opinions.

Even as the video-sharing app has grown in popularity, the inner workings of its complex, artificial intelligence-powered algorithms remain a mystery.

Individuals see only a fraction of the content posted on TikTok every day. And what they see is highly curated by the company’s automated systems designed to keep people glued to their smartphones. Using AI technology called machine learning and so-called recommendation systemThese systems determine within milliseconds what content to display to social media users.

Politico shed light on how TikTok’s algorithms work, and how to uproot which side in the war in the Middle East – Israeli or Palestinian – was winning hearts and minds on the social network, which is now overwhelmingly followed by young people. Actually being liked.

This has become a hot political question after pro-Israel groups and some Western lawmakers accused TikTok, owned by Beijing-based ByteDance, is unfairly promoting pro-Palestinian content for possible political influence. TIC Toc deny the allegations,

The political effects of the conflict are already evident in partisan clashes in Western democracies as people choose sides in the war – and decide how to vote. US President Joe Biden’s support for Israel Criticized by Arab-Americans, and it could ultimately cost them the November election. In the United Kingdom, populist independent candidate George Galloway used pro-Palestine sentiment to win a seat in the British Parliament in March. Protest in university campus have burst into tears But both sides Of the Atlantic.

TikTok’s algorithms are crucial to how political content of all types reaches social media feeds. Examining a company’s algorithms is a good proxy for how artificial intelligence is now a major player in determining what we see online.

Politico teamed up laura adelsonA researcher from Northeastern University in Boston tracked pro-Palestine and pro-Israel TikTok content over the four months between October 7, 2023, and January 29, 2024.

This involved creating a list of 50 popular hashtags such as #IStandWithIsrael or #SavePalestine that could be directly linked to either party. More apolitical hashtags like #Gaza or #Israel were used to collect data on posts that had no specific leaning.

In total, Adelson analyzed 350,000 TikTok posts from the United States.

To make the data more digestible, she broke posts into three-day windows around specific events. This includes Hamas’ initial attacks (7–9 October); Israel’s offensive on Gaza (October 27–29); And to control for the release of the first Israeli hostages (24–27 November) bias, they also included 6–8 November in the analysis, as a proxy for the period when no major events occurred.

“Like other social media platforms, TikTok amplifies some content more than others,” Adelson said. “This can have a distorting effect on what people see in their feeds.”

What emerged was evidence that TikTok is grappling with its role – in real time – as one of the main global digital city squares where people gather to express their opinions and often disagree.

Over a period of four months, Adelson’s research Based on the hashtags analyzed, it was found that pro-Palestinian content was produced approximately 20 times more than pro-Israel content. Yet this does not necessarily equate to more pro-Palestine posts appearing in the average person’s TikTok feed.

Instead, Adelson found three distinct times when the likelihood of people seeing pro-Israel or pro-Palestine content in their TikTok feed changed markedly — no matter how much overall content was being produced by both sides. Was.

TikTok did not respond to specific requests for comment about the Northeastern University research. one in blog post In April, the company said it had removed more than 3.1 million videos and suspended more than 140,000 livestreams in Israel and Palestine for violating its terms of service.

There is a lot that is unknown about how these social media algorithms work. It is not clear who within the companies – engineers, policy officers or top executives – determines how they function. It is also difficult to determine when changes are made, although regulatory efforts in the European Union and the United States are trying to shed a broader light on these practices.

What follows is an example of how, when you dig into the numbers, much of what users see on social media depends heavily on complex algorithms that are used very rarely on a regular basis. – If any – are replaced with inspection.

October 7 – October 27: Pro-Palestinian content dominates

October 27 – December 15: Pro-Israel content takes off

Many people – especially those over the age of 30 – consider video-sharing networks to be a sham, mostly a dance craze and digital craze that has nothing to do with politics.

They are wrong.

Adelson said TikTok is similar to other social media giants in that its algorithm was designed to promote what was popular. The logic: serving people what they want to see so they stay as long as possible.

It’s okay when it’s viral videos of dogs or cute babies. It’s an entirely different thing when it’s highly charged political content about a geopolitical hotspot where people are dying every day. Such events leave social networks like TikTok and their automated curation models in the unenviable position of determining what is popular – at the risk of eliminating minority opinions.

“When it comes to politics, like anything else, social media discourse prioritizes the majority,” Adelson said. “We should think very seriously about what this means.”
