69 / 100
Mostly True United States

X's algorithm prioritizes engagement, often showing users content they dislike, impacting Democrats more. Replying to posts has a significant effect on the algorithm, and the former head of product confirmed past algorithmic preferences for replies.

Infact verdict: Mostly True (69/100).

The claims about X's algorithm prioritizing engagement and serving more ragebait to Democrats are supported by a study published in the Proceedings of the National Academy of Sciences. This study indicates that the algorithm prioritizes engagement, often by showing users content they dislike, which aligns with the claim. The claim that replying has an outsized impact on the algorithm is supported by evidence showing that replying significantly boosts engagement. The statement about Democrat users confronting value-misaligned content is corroborated by the study's findings on feedback loops. Lastly, the claim about the former head of product confirming past algorithmic preferences for replies is supported by statements from Nikita Bier, although he notes this is no longer true.
