A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’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 I’ve read in awhile.

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.

Another ruthlessly ambitious (and unlikeable) defector. A thought: if they can't push above 30%, it's a hung parliament in 2029 with probable coalition locking out Reform. Next shot is 2034. Farage is now 70, and has kept the party, full of jostling egos, from imploding for eight long years...

🚨 BREAKING 🚨 Suella Braverman defects to Reform UK. Another failed Tory joins Farage. Vote for Reform UK, get the worst of the Tories.

Despite becoming a yawn-inducing attack line it is still *extraordinary* that in the early 2000s Britain's Labour government decided to sell off half the country's gold reserves when the price was where it was. 395 tonnes, which then netted $6.3bn (adjusted), would today fetch $52bn 😳

I'm a "glass is half-full" kinda guy, so let's look at the upside of the Riyadh Comedy Festival: We never, ever have to even pretend to take any of these "anti-woke" "free speech warriors" seriously, ever again. New from me at @opinion.bloomberg.com (gift link): bit.ly/4h51JjF

Will Anti-Woke Comedy Recover From the Riyadh Festival?

Any event that includes comedy’s biggest names is going to attract attention — but the Riyadh Comedy Festival, which kicked off on Sept. 26 and continued through Thursday, is disproving the adage that...
