It can be difficult to grasp just how recent the Mexicanization of America is. In the 1970s, less than 70,000 net Mexicans were immigrating per year. Then from 1980-2010, you had about 700,000 net migrating every year, on top of Baby Boom levels of TFR.
Mexico net annual migration by decade using births and census counts: 1940-1950: 20k 1950-1960: -70k 1960-1970: -145k 1970-1980: -67k 1980-1990: -751k 1990-2000: -717k 2000-2010: -643k 2010-2020: -206k

This - the state funding lawyers to sue the state to compel it to do leftist things - is one of the most important ways modern Western governments coordinate. It's very Kafkaesque.
Replying to @Peter_Nimitz
We have a large and complex network of state funded NGOs that sue the state on a variety of causes. No specific one for only housing I think, but it isn't needed, they get free legal assistance for almost every cause and they already have priority on housing over natives.

Skip California entirely and spend the money that would take to increase the rest of the high-speed national railway maybe 20% more miles, including Albuquerque and Anchorage Alaska. Make Salt Lake City a hub.
Here is my proposal for a US High Speed Rail Network! A lot of research went into this map, and I tried to be as unbiased as possible. Thoughts?

Aging and the selection-decline effect should grow beyond thinking in terms of an overall effect spread evenly, but will eventually consider specific traits that are selected upon differently across the lifespan. This should generate new and interesting testable hypotheses!
Aging may not be a steady downhill process it may happen in stages A large study of over 4,000 people aged 18 to 95 analysed nearly 3,000 proteins in blood plasma to understand how the body changes over time. Because these proteins reflect key biological activity such as immune function metabolism tissue repair and cell communication they act as a snapshot of how the body is aging Researchers expected gradual change across the lifespan. Instead they found something more complex many proteins linked to aging shifted in noticeable bursts rather than slowly over time These changes appeared to cluster around roughly three key life periods around the mid 30s around 60 and again in the late 70s suggesting that aging may happen in waves rather than a straight line The shifts were connected to systems like inflammation cardiovascular health immune response and energy metabolism hinting that the body may periodically reorganise itself biologically at certain stages of life Using just a subset of around 373 proteins scientists were able to estimate a person’s age from a blood sample with an average error of about three years. Interestingly individuals whose biological profiles appeared younger than their chronological age also tended to show better overall health The research also highlighted strong differences between males and females with a large proportion of age related proteins behaving differently in men and women suggesting that aging pathways may not be identical across genders Overall the findings challenge the idea of aging as a smooth decline and instead point to a process that may unfold in distinct biological phases

One thing that’s treated very flippantly by the plastic surgery people is how significant going under general anesthesia is for your long term health. Going under one time is equivalent to a concussion in terms of brain damage. It should not be done frivolously.
Community note
This is false. General anesthesia does not damage the brain in a way that equals a concussion. there’s no evidence of this at all, frankly, just untrue hms.harvard.edu/news-events/pu…

Among the Ache and Hadza hunter-gatherers individuals interact with over 1000 others over their lifetime. I don’t think 100 is plausible for the vast majority of historical hunter-gatherer societies
Ben Affleck says you're supposed to live in a village and see about 100 people in your entire lifetime "we weren't made evolutionarily as human beings like we're supposed to be living in a village and see about 100 people in our lifetime" "that's the vast majority of human history...that's how we did it and I still feel like in a way that's how we're socialized...it's why if you feel left out of a group it's very painful" "even social media for example you looking at stuff you know damn why is everybody life is so good...that's also is a basic primal thing"

Watch this video below. Shocking that it was aired on CNN. By @FareedZakaria no less! All the problems he describes in California result from total Democrat control of the state for years. And that total control / no competitive elections result from election laws written that way on purpose. By the politicians who care only about staying in power. This is the same result EVERYWHERE when the election system itself is designed to take the power from the voters and hand it to the governing officials. Where the voters no longer choose their leaders - because the leaders have rigged the process to perpetuate themselves, to ensure their continued power and control. The election system in California is based NOT on access to and control by the voters. No. Instead, the election laws in CA are designed to vest total access to and control of the election process by the politicians. @EIwatchdogs published the Model Election Laws Handbook last month: the blueprint to repair the damage done to America’s election systems by the Democrats’ Leftwing Corrupt Elections crowd over the past 30 years. Who has attacked the Handbook repeatedly in the past month? @marceelias - yes, a key architect of the corrupt elections in CA and other blue states. The pro corrupt elections cabal wants EVERY state to be California- where the Democrat politicians control the election results. California’s inability to govern itself is a result of corrupt elections and NOTHING will or can change until the CA election code is completely replaced with laws such as those in the Model Election Laws Handbook. modelelectionlaws.org It is a binary choice: either the system has integrity, so the voters control the outcome OR the system is corrupted by politicians who control the outcome. There is no substitute in a constitutional republic for honest, transparent, and accurate elections. That’s real voter access. Not politician access. Until the voters control the outcome of elections in California - and everywhere - the political ruling class will continue to do what it has done in California and, frankly, in every blue state. Join the election integrity movement. Help save our country. And even save once proud but now sad places like California ElectionIntegrityNetwork.org
💥NEW: CNN’s Fareed Zakaria *DELIVERS BRUTAL TAKEDOWN* of California’s “FAILING MODEL OF GOVERNANCE”💥 “The frustration is real and JUSTIFIED… it is a case study in how a rich society can spend more and more — while producing less and less of what its ordinary citizens need.”

2/ The vast majority of ways to make a mark on the world require tools, skill, and space / property. To an acceptable approximation, in 2026 no one under the age of 29 has a backyard, a circular saw, or a set of sawhorses. The only mark that 99% of people can make is a wound.

As this is doing numbers let me elaborate a bit. The traditional definition of what counts as original is indeed quite restrictive. Obviously once civilization advanced and writing spread, all writing was likely to be influenced by some other. Still we must acknowledge the influences. Some derived scripts were more innovative than others. Latin from Greek was a very small change. Greek from Phoenician was a pretty big one. New category, abjad to alphabet. Brahmi from Aramaic was also a big jump, abjad to abugida. Indians deny the descent but they deny everything. Hangul was very innovative too, but the influence of phagspa is undeniable. At any rate, if you change the taxonomy to classify the more innovative scripts as original, you get a category including hieroglyphs, Chinese, Brahmi, Hangul. If you include those with no graphic resemblance, you get those plus Glagolitic, Georgian, Armenian (made to look different to Greek on purpose), Deseret. Those just aren't useful categories at all. The traditional taxonomy on writing system is about understanding the history of the spread of writing. And the history says there are two extant branches, Egyptian and Chinese. QED.
Every single living writing system besides Chinese is descended from Egyptian through Phoenician.

Kurt Gödel's two Incompleteness Theorems were four years before Alonzo Church's Lambda Calculus, a kind of third theorem perhaps? (For any sufficiently complex system you can't prove it contains no contradictions. Nothing's perfect. Consilience and comparative methods matter.)
In 1936 Alonzo Church tackled a question logicians had circled for decades: is there a method that can decide for any mathematical statement whether it is provable? To make the question precise he invented a tiny language where everything is a function: the lambda calculus. He used it to prove that no such method exists. Months later a student of his named Alan Turing reached the same conclusion with an imaginary machine. The two proofs were equivalent, and together they drew the line between what a computer can and cannot do. Church built half the foundation of computer science to settle a question about logic. The lambda calculus he invented is still running today, inside every functional programming language.

Average SAT by major at Columbia. Classics improbably edges out Math and Physics for the top spot at 1529. Sociology is on the bottom (1422), though "Ethnicity & Race Studies", "Public Health", and "Human Rights" aren't too far in front. The within-school spread is 100 points or so — around half of a standard deviation of the SAT-taker population.

Five reasons the twin findings of very high heritability of IQ) remain important are: 1. Twin studies capture the entire genome and all types and modes of genetic variant and effect (baring denovo mutations etc.). 2. They capture and expose variance both within and between families: 3. They are the reality on the ground: a) MZ twins are as similar in IQ as the same person taking the WAIS twice (!) b) DZ twins sharing half their DNA are only half as similar. 4. If indirect effects of parental DNA are active for IQ, then this is is the extended phenotype of IQ. Rather than something to dismiss as "not h^2", it reveals that the selective benefit of the IQ adaptation includes: a) Creating high SES niches for one's offspring. b) Responding to the needs of the infant. That's everything from things as simple as treating crying etc as a need to respond too and effectively solve. More broadly, parental IQ enables the evoked environment: Answering questions about calculus or why the sky is blue accurately, curiously, and responsively. Buying engineering toys if that's the child's interests lie, or art or music or... c) Supporting training and investing in the offspring's adult journey. 5. If part (or all) of apparent indirect genetic effects result from assortative mating, that too is not to be dismissed. Assortment is key to the ability distribution of the next generation and the variance of IQ and it creates a massive genetic conveyor belt sorting alleles so they end with other alleles point in the same phenotypic direction. a) People choose mates about as well as they could if they received WAIS scores from potential partners and made maximizing that a top priority. b) Assortative mating pumps in variance in genetics (making more high (and more low scorers) than would happen at random). c) The exceptional parents are aligned with their exceptional offspring. d) If high ability couples fail to have offspring that's a double whammy for the next generation. There's much more we learn from twins, but that's plenty of reason they are as important as ever and the higher than current SNP-based heritability estimate is important as ever. As Alex says, academia is perversely silent on all of this.
