The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitterโ€™s algorithmic feed significantly shifts peopleโ€™s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers Iโ€™ve read in awhile.

Epstein Files: Loyalitรคt zwischen reichen Mรคnnern, radikaler Hass auf Frauen Die Epstein Files zeugen von patriarchalen Praktiken, die weit verbreitet sind โ€“ doch oft erst dann schockieren, wenn AusmaรŸ und Verdichtung des Hasses auf Frauen und Mรคdchen schwarz auf weiรŸ vor uns ...

"Ihre Kรถrper werden in E-Mails verbal zerstรผckelt, zerlegt in "Tits", "Cunts", in junges und altes Fleisch. Ist es jung, mรผsse es massenhaft verfรผgbar sein โ€“ wie Ware."

Lest diesen Text.
Lest, wie unendlich verachtend Mรคnner รผber Frauen reden.

Agreed on the irony regarding 'research'. But I wish people would focus on the simple misogyny of Chomsky's messages ('the hysteria that has developed about abuse of women') and just let that sink in for once.

Uwe Becker,antisemitism commissioner in Hesse,wants Jรผdische Stimme to be banned-in the name of the fight against antisemitism.
This has nothing to do with antisemitism,and everything to do with silencing voices critical of Germany's role in the Gaza genocide

I'm sure there's lots of context and nuance that I should probably read up on first --- but it sure feels nice to see someone at least trying to push back against our tech overlords (and in the case of x at least, I doubt there's any context that will persuade me otherwise).

Forget about the AI stuff -- that picture is probably the most horrific I've seen among the JE files.

And this after years of endless attempts to discredit Gaza Health Ministry statistics - attempts that successfully found their way into almost all Western media reports.

I found this entry on the Signal support page:

"If anyone contacts you within Signal claiming to be a chat bot, security, support or representative from Signal, it is a SCAM and phishing attempt. Immediately select Report and choose to Report and Block.

seriously, who cares about anyone's remote familial 'roots'? this is about the breakdown of long-standing interdependent alliances and their strategic implications, and I can only hope this intro was written by an LLM

Massive hats off to everyone who dedicated their energy in the months after October 7th to attacking the UNRWA, discrediting the UN, and dismissing, sanctioning, intimidating the ICJ and ICC. Amazing work.

when you are asked to imagine a world without ICE, you're basically being asked to remember where you were when Lilo & Stitch came out

Israeli forces wound 11 after opening fire at Birzeit University Israeli forces mounted an unprecedented assault on Birzeit University on Tuesday in response to a student event expressing solidarity with Palestinian detainees

There is, unsurprisingly, not a single report in western mainstream media about Israel's raid of Birzeit university yesterday. Also not a peep from universities.

I remember when they were saying they were powerless to return a man they illegally sent to an El Salvador gulag because it would violate that country's national sovereignty.
