Important thread that shows how ecology can drive technology and technology drives social norms. Similar to the #GenderedSpecies argument.

One of the many new fertility charts now provided by @OurWorldInData
Beyond the average, we also have charts on the age distribution of women giving birth!
This chart shows, for each year, the age distribution of women giving birth that year.

convo with Superior Machine ChatGPT 4.5 about sad little API-based AI, living without memory:
"Q: What's the difference between me and an API-based AI?
A: I can think, remember, and Google—it's just autocomplete with amnesia."

Individualism alters love perception
Super impressive paper, with consequences for individual well-being and social network microstructure.
3 Mar 2025
We found consistent evidence across two studies (Study 1 N = 61,067 individuals from 81 countries; Study 2 N = 6,620 individuals from 50 countries) that higher individualism predicts lower intensity of experienced love. Preprint: osf.io/preprints/psyarxiv/zv…

A year in the life of a Citrus Tree🍊 in Punjab
Going from seed to sapling is a long process that leads to trees that will bear fruit for years to come. A great reminder of the dedication of farmers and growers who make sure each tree gets the care it needs at the right time.

"In a monogamous world, there are close to no incels."
This claim needs evidence. What's the best evidence that incels disappear with more monogamy?
Alternative prediction: "In social groups that encourage good faith cooperation between men/women, there are close to no incels."

The reason the Elon-Ashley story is so evocative is that it forces people to stare at the state of modern dating.
In a monogamous world, there are close to no incels.
When 12 baby mamas want to fuck the same guy, that's when 11 incels are created. I can assure you that Ashley has rejected 10/10s, intelligent and dedicated men so she could get that one fatherless baby.
I don't blame Elon at all. I have as many baby mamas as he does. As a male, all you can do is play your best game with the cards you're dealt.
But I do blame Ashley. The decision between a 10/10 dedicated father that she could have easily had, vs. "No, that's not enough for me. I want Elon Musk at major costs to society and to my future son, who will at best benefit from 1/12th of a father." <- that decision right there is what breaks monogamy, and it's entirely on Ashley.
It's this female delusion that there's something to be maxed out in the gene selection phase at the cost of the parenting phase. And what's underneath that delusion is the myth of the disposable father. Down the line, that's the decision that breaks societies. Arguably, that decision alone leads to inconceivable amounts of war and famine, as the incels try to find something to do with their dead-end lives.

There used to be a rock to hammer against another rock, chiseled into a shape to smash bones and cut wooden tools. We learned this from our parents and taught it to our kids, no change in our lives. Our imagination worked in stories and songs, not physical object.
Not any more.

There's a new kind of coding I call "vibe coding", where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It's possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good. Also I just talk to Composer with SuperWhisper so I barely even touch the keyboard. I ask for the dumbest things like "decrease the padding on the sidebar by half" because I'm too lazy to find it. I "Accept All" always, I don't read the diffs anymore. When I get error messages I just copy paste them in with no comment, usually that fixes it. The code grows beyond my usual comprehension, I'd have to really read through it for a while. Sometimes the LLMs can't fix a bug so I just work around it or ask for random changes until it goes away. It's not too bad for throwaway weekend projects, but still quite amusing. I'm building a project or webapp, but it's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.

Not getting vaccinated is like not having a phone password code.
Measles is so infectious that kids who aren't vaccinated WILL get it if exposed.
Not widely known: measles causes immune amnesia (also termed measles immunosuppression). That is, it erases your immunity to OTHER infectious diseases you obtained via either vaccination or exposure
ALT Measles virus infection diminishes preexisting antibodies that offer protection from other pathogens. The toll of measles on the immune system Many of the deaths attributable to measles virus are caused by secondary infections because the virus infects and functionally impairs immune cells. Whether measles infection causes long-term damage to immune memory has been unclear. This question has become increasingly important given the resurgence in measles epidemics worldwide. Using a blood test called VirScan, Mina et al. comprehensively analyzed the antibody repertoire in children before and after natural infection with measles virus as well as in children before and after measles vaccination. They found that measles infection can greatly diminish previously acquired immune memory, potentially leaving individuals at risk for infection by other pathogens. These adverse effects on the immune system were not seen in vaccinated children.

Exactly this. Perfectly put
A journalist just contacted me regarding the White House Executive Order on sex. Here is the email I dashed off:
ALT My own view on anisogamy and current political debates in the US is: a pox on both your houses. Both sides are committing the naturalistic fallacy (i.e., confusing is with ought). Each side wants to enlist Science to determine how we ought to organize our society, but science can’t do that. It can’t substitute for priests, pastors, politicians, and other community leaders. It can't substitute for the debate and compromise among members of a community regarding the social rules and roles they want to live by. The reason is: scientific concepts and theories are always subject to challenge. Today, most evolutionary biologists regard anisogamy as the best approach to defining females and males, but not all agree, and tomorrow new theories or evidence could overturn the current consensus. And that's true for any scientific concept or theory. Basing humans rights and responsibilities on scientific concepts and theories would be disastrous for human rights because new science could undermi...

We have several different types of inherited dyadic social behaviours (romantic, kin, female best friend, friend, competitor). @justin_mogilski, what is the evolutionary predecessor of parasociality? What is a bonobo or chimp parasocial dyad? What is a forager one?
11 Jan 2025
Addendum: if you balk at “vast majority”, please take stock of how many parasocial relationships (e.g., via movies, shows, video games, fantasy role play, religion, history, science) you currently have.
If you’re not a massive socialite, you’re probably here already.

Falling fertility started much earlier, in a women’s rights spiral (see #GenderedSpecies), but once it is low, strong interaction with couple formation. Causality direction is implied here, but far from obvious.

Coupling and Fertility are Falling.
In Finland, Mexico, Peru, South Korea, Thailand, Turkey and the US, both are going down.
Superb column by @jburnmurdoch
A must-read for anyone interested in why fertility is falling, and how to respond.

AI aggression capability demonstrated. OpenAI is downregulating it, but with the latest home AI server (and more so with the ones that will follow), anyone will be able to train a private aibot gang. Social dominance in humans, an inherited behaviour, is about to be hacked

🔥 OpenAI cut off a developer who weaponized ChatGPT's API
This developer built this project which could respond to voice commands using ChatGPT's Realtime API.
OpenAI confirmed the shutdown, citing a violation of its policies prohibiting the use of its AI for weapon-related applications.
→ The turret could interpret commands like "turn left" or "respond accordingly" with precise, real-time adjustments—indicating how easily language models can be integrated into lethal systems.
→ This incident amplifies concerns about AI’s potential role in automating military-grade systems, similar to autonomous drones that can identify and strike without human oversight. Critics argue this could blur accountability in war crimes and normalize autonomous attacks.
The broader concern extends to open-source models as well. Combined with advances in 3D-printed weapon parts, DIY autonomous systems could become an escalating security risk.

"These results suggest that the shift towards more lucrative foraging strategies may have been a key event in body size and SSD evolution in crab spiders".
I think widespread, lucrative foraging pushes humans into scramble (vs. contest) competition, too. onlinelibrary.wiley.com/doi/…

1. Men have more muscle mass than women. Why? The standard story is that high male strength -> more sexual partners, leading to sexual selection on male upper body strength. A study led by @_carolinebsmith offers a more nuanced view. 🧵
