1/ X's algorithm was changed in mid-July 2024 to systematically boost Republican-leaning accounts and Elon Musk's own account following his endorsement of Donald Trump, according to a newly released computational study of engagement from the Queensland University of Technology.⬇️

2/ The study, by Professor Timothy Graham of the QUT and Professor Mark Andrejevic of Monash University, analysed 56,184 posts sent by a number of accounts between January 1, 2024 and October 25, 2024 and examined view counts, retweet counts, and favourite counts for each.

3/ The analysis found "a structural break for Musk's metrics around July 13, 2024" following which his view counts increased by 138.27% and retweets increased by 237.94%, with a similarly large increase for favourites. This was far in excess of other accounts monitored.

4/ The authors conclude that the results "indicate that Musk’s posts received a marked increase in visibility (view counts), amplification (retweet counts), and user interaction (favourite counts) that outpaced the general engagement trends observed across the platform.

5/ "The unique post-change uplift for Musk's account suggests the possibility of algorithmic prioritisation or bias, positioning Musk's content favourably in terms of platform visibility and user engagement."

6/ The analysis also found a large increase in view counts, retweet counts, and favourite counts, for Republican-leaning accounts, but not for Democrat-leaning ones. Again, the break point for this appears to be July 13, 2024, suggesting a platform-wide algorithmic change.

7/ The authors conclude: "Republican accounts benefited from increased visibility or recommendation bias post-change."

8/ "This could imply an algorithmic adjustment, potentially in the For You feed, designed to place certain content in front of more users, thus driving up views selectively for these accounts."

9/ Musk made his endorsement of Trump on July 13, 2024. The analysis suggests that Musk did more than merely give verbal support for Trump, but also changed X's algorithm on the same date to systematically promote his own and other prominent pro-Republican acounts. /end
