Non-natalism – Spectre Journal A case for being against pronatalism Leslie Root shows how misguided it is for the left to accept pro-natalist positions. Worry about declining birth rates is based on a misinterpretation of the Total Fertility Rate, and minor social pol...

New NHS England Review Excluded 97% Of All Trans Studies To Say Care Doesn't Work The new review has led to a ban for HRT through the NHS England system under the age of 18.

1. A new NHS England Review excluded 97% of all trans care studies to conclude that trans youth care doesn't work.

It explicitly violates several guidelines around reviewing literature, and appears to be politics masquerading as (shoddy) science.

Responsive, attentive health care shouldn't be the exception for fat people. It should be the rule.

Having good experiences with HCPs feels like a glimpse into what a world with more thoughtful care for fat patients could look like. & it makes me want to triple down to bring that world about.

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 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.

There’s a boom in papers claiming:

1. Graphs only model “pairwise interactions”

2. Hypergraphs uniquely capture group interactions

3. Many systems are better modeled that way, and

4. They reveal new phenomena.

I’ve rarely seen claims this misleading repeated so often and so uncritically!

I briefly touched on Epstein’s connection to transhumanism/eugenics, but the latest drop had even more explicit connections to almost all of the dudes I talked about. Goertzel, Thiel, Yudkowksy, Musk. All of them talking about cryonics and immortality and superintelligence. Def worth exploring more

Question for the brick wall: What concept would you consider an essential inclusion in a "Quantitative Reasoning for Computational Social Science" class where the only prerequisite is basic programming?

No math requirement but I'd hold their hands through some basic calculus and linear algebra.

When does it become appropriate to connect the president's decades-long push to expand the death penalty to the current project to abduct and imprison political dissidents? When do we take seriously the threat that he may attempt mass extermination?

One of the first things anyone learns about facial recognition is that it is often wrong and that it is biased. And yet ICE is using it all day every day to determine legal status & who to detain. And now we have a high-profile example of it being flat out wrong:

Over the last year the entire "free speech on campus" beat has been revealed as an utter fraud. Years of punditry puked out in ignorance and bad faith.

Yet even as the fraud becomes undeniable we still get stories about wide-eyed idealists who just wanted 'ideological diversity' and 'open debate'.

Listen to Bad Bunny: Abolish Act 22 An egregious tax-evasion loophole is inflaming the displacement crisis in Puerto Rico.

Average rents in Puerto Rico have skyrocketed 600 percent since 2017 as properties have been bought up by newcomers. It's unaffordable for locals to live on their territory.

ICE opinion is shifting from lefties (a little) + reality (a lot). But it's happening much more slowly than it would on the right, because a, our partisan media is comparatively weak, and b, three-quarters of Dems are still prioritizing Seeming Moderate over stopping ICE from murdering moms.
