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 Twitterβs algorithmic feed significantly shifts peopleβs political views to the right.
Moving from chronological feed to the algorithmic feed also increases engagement.
This is one of the most concerning papers Iβve read in awhile.

When someone says βScientists do not want you to knowβ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They canβt shut up about what they found out and want you to know.

Trading on Violence
Insider trading on prediction markets is turning into a dog-bites-man type of story.
On Polymarket, transactions are visible but identities are not. This invites not only insider trading but also, as recent events suggest, potential betting directly on & profiting from geopolitical violence, as CASBS fellow @rajivsethi.bsky.social explains

Merlin also says it caught a Hammondβs Flycatcher, but that would be rare. However, it seems a couple have been sighted within ~100 miles recently. So, I will keep an ear out.

It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab?

For a country to survive, there has to be a common culture.

Nobody dies to defend a "multicultural economic zone"!
American culture, with its English-Scotts-Irish origin, is great and worth fighting for.
Some may not realize it, but that's why people come here.
Black soldiers in WW2
Members of the Japanese American 442nd, the most decorated (and most wounded) military unit in US history
Navajo Code Talkers
Billionaire racist Elon Musk, erasing the fact that millions of βmulticultural Americansβ have died defending multicultural America, often while white supremacists like Elon Musk fought tooth and nail to deny them the basic civil rights accorded to white Americans.
