Millions of people are about to die in the coming weeks and months, protracted and painful deaths, unless the government steps up and acts NOW.

This is not hyperbole. I’m not exaggerating. Left unchecked, that will be the outcome of the COVID19 coronavirus pandemic in the U.S., as well as in many other countries across the world. We still have a chance to stop this, but if the response continues to be what the American government is doing, we’re in dire straits.

To all my readers.

It’s also worth mentioning that the third addition to the JayMan family, Little Mister JayMan arrived last month. He’s celebrating his first Christmas with his family. Enjoy your holiday!

Forests, Trees, and the Hajnal Line

Anatoly Karlin recently wrote a post criticizing my and HBD Chick’s attribution of socio-cultural-economic differences across Europe to our old friend the Hajnal line.

The Hajnal line is a border that links Saint Petersburg, Russia and Trieste, Italy. In 1965, John Hajnal discovered it divides Europe into two areas characterized by different levels of nuptiality. To the west of the line, marriage rates and thus fertility were comparatively low and a significant minority of women married late or remained single; to the east of the line and in the Mediterranean and select pockets of Northwestern Europe, early marriage was the norm and high fertility was countered by high mortality.[1][2] [Wikipedia]

Anatoly’s arguments on this matter often rests on his inability to fit some social pattern or another perfectly to the geographic extent of the Hajnal line, as he’s wont to do. This is very much his M.O. on these things, he seems to expect perfect geographic correspondence with every social variable to the Hajnal line. It should be obvious that this is not going to happen, and it should also be obvious why. But since it’s apparently not, let me explain here.

(Now, don’t take this post to be a dig at my pal Anatoly. He’s a good force for HBD at a time when it’s badly needed. But this is a common error of thought he and others commit that I wanted to address here.)

Anatoly’s particular aim in his post is to run afoul Occam’s Razor and argue for the importance of the existence of the Iron Curtain in shaping socio-cultural values in today’s Europe, long after the Iron Curtain disappeared.

Yes, we can see that the Hajnal Line explanations do play a substantial role – e.g., Portugal, Italy, and especially Greece are rather conservative relative to Western Europe – but these effects are swamped by the effects of the Iron Curtain, as well as local effects (e.g. Poland vs. Czechia on religiosity, whose roots may stretch back to more than half a millennium). (emphasis mine)

Communism: is there anything it can’t do? It’s like the legacy of slavery for American Blacks. Its effects are felt long after its gone. And in both cases, the legacy is felt before it even existed:

That’s some powerful shit, that communism. Its power to shape outside Hajnal societies projects past, present, and future!

Obviously that’s silly. In that case, what is really going on? Why do I say that the legacy of communism is a bad explanation for what we see? Why don’t cross-national social variables fit perfectly to the line, as Anatoly often points out?

Anatoly’s nitpicking for things that sometimes don’t fit the Hajnal line well of course ignores the enormous number of socio-cultural variables that do follow the Hajnal line. A simple search on my Twitter for “Hajnal” turns up many of these:

And of course I have a whole series of posts talking about this (which is a great place for newcomers to this topic to start to get up to speed with what I’m talking about here):

Clannishness – the Series: Zigzag Lightning in the Brain

There’s Anatoly’s problem: he can’t see the forest for the trees!

The thing is that the ultimate source for the differences between different groups of people living at the same time in different places is biological differences between those people. That is the reason the Hajnal line pattern we see exists and has effects that continue to be felt in many different social spheres. The people outside the line are biologically different from people inside the line. The reason for this is due to differences in the historic selective pressures that operated inside the line vs. outside the line. The broad differences are discussed by me here:

Clannishness – The Series: How It Happened – The Unz Review

But why the lack of perfect correspondence then, across different social variables? Given the above, this too should be obvious. The reason is that the selective pressures each specific population experienced were unique. Every society is different from every other society. However, there were patterns in this selection that varied in part due to geography that helped to produce the geographic patterns we see.

Hence, there isn’t going to be perfect correspondence across socio-cultural variables to any geographic pattern. Neighboring populations may be more similar in some respects and less similar in others than simple proximity would suggest. One poignant example is slightly stronger tolerance for homosexuality in Iberian populations and their derivatives than simple geography might suggest (see my post The Rise of Universalism). This should all really go without saying, but I’m saying nonetheless. Indeed, I’ve touched on the fine-grained differences of European populations, particularly intra-national ones in my post here:

Clannishness – The Series: A Finer-Grained Look at How It Happened

In Europe, migration is partly responsible for the Hajnal line pattern we see (e.g., the Ostsiedlung

But, much of the differences we see across European populations is due to in-situ selection. That said,  all of this equally applies to the American Nations:

I’ve produced a ton of maps in my American Nations Series in a similar vein to the Hajnal line differences across Europe. Here, migration is the bigger factor rather than in situ selection (since there hasn’t been much time for it, but make no mistake, some selection has occurred). In North America, the differences stem from founder effects (the initial settlement), subsequent immigration, an assortative (self-selective) migration.

Now you may ask, but surely the legacy of communism had to have some effects, right? Long-time readers know what I think about that. But for new readers, I say again that thinking that communism is to blame for the lower average social liberalism and higher average corruption of outside the Hajnal line Europe –30 years after communism’s disappearance – is like thinking slavery is to blame for the lower average IQ and high crime rates of American blacks. It’s the sociologist’s fallacy, this time in a historic context. East and West Germany remain different from each other, long after the Berlin Wall fell. But more importantly, they were different to begin with and have been for some time. 

Communism remains in place in North Korea, but North and South Korea had long historic differences, from long before the Korean War. Were the Koreas to reunite, differences would remain, just as they have in Germany.

The reason for this is because, ultimately, as Greg Cochran said, “every society selects for something”. And of course, what that something is varies from society to society (often in systematic ways).

It’s worth noting that Peter Frost published a paper not too long ago that basically ripped off HBD Chick’s idea without giving her any attribution. I must say (as I’ve said before) that I’m deeply disappointed in Peter for doing that. He, I, and Chick have been on the same page on a lot of things on the topic of HBD for a long time, and it’s a shame to see him stiffing her out of her due like this.

I don’t expect this post to change certain minds, but it should be a useful piece for those in trenches on HBD and the Hajnal line.

As always, my tip jar is very much open, especially now for reasons that will become very apparent in the next post. If you want to make a donation, it’ll be great appreciated!

Funding Drive: Moving!

(Image source)

For various reasons (ultimately, mostly bad reasons), my family and I need to move to a new place. This is unplanned, and it would be a severe understatement to say that we, as current, do not have enough to cover moving expenses. And, as readers know, we have another child on the way.

So, once again, I am turning to my readers and followers to for help.

EDIT: I’m adding a counter of donations received to date (will update daily):

US $300

I can’t promise my readers I’ll be any more active. If anything, between an upcoming move and a new child arriving after that, I’ll be significantly less active. Nonetheless, if you would, please donate:

If you prefer, I will also take Bitcoins:

So, once again, let’s review some of my greatest hits so you can see why you should support the JayMan. There’s my introduction to those new to the topic of Human Bio Diversity (HBD), my thorough (but soft) introduction to the matter that I’ve written:

JayMan’s Race, Inheritance, and IQ F.A.Q. (F.R.B.)

This will get you started.

Of course, there was my interview by Robert Stark (of The Stark Truth). That interview is up as a podcast here:

Robert Stark interviews Jayman – The Stark Truth With Robert Stark

Mainstream discourse, including the media (and a good part of the scientific establishment itself) spreads false information. Whether it be on IQ, race, heredity, parenting, diet, health, lifestyle, or homosexuality, complete rubbish rules the day. I have attempted to remedy this here.

To learn about me, please see my About Me page. There I talk a little about my background as well as provide a roadmap to my earlier publications, including the key pieces new readers should see.


Your first reading after that should be this. The foundation of HBD and indeed all human biological research is behavioral genetics. This has produced four (well, five) laws that are fundamental, the first of which is the plain statement that Did you know that parenting (beyond ensuring your children are healthy and safe and have basic human interaction) has no real impact on how children turn out as adults? That’s right. Read all about it:

The Behavioral Genetics Page


My earlier posting 100 Blog Posts – Reflection on HBD Blogging and What Lies Ahead reviews the topics I’ve talked about in the beginning, including fertility trends, and health and lifestyle wisdom.

My post 200 Blog Posts – Everything You Need to Know (To Start) is just that. Here I review the topics I’ve discussed in the preceding 100 posts, including the matter of guns and violence, the American Nations (the regional ethno/cultural/political divides across North America), and the problems with some of the people who talk about this topic.

A key thing is my series on clannishness, discussing HBD Chick’s work:

Clannishness – the Series: Zigzag Lightning in the Brain

And about those American Nations, my page American Nations Series indexes the posts I’ve written based on the books American Nations: A History of the Eleven Rival Regional Cultures of North America by Colin Woodard and Albion’s Seed: Four British Folkways in America by David Hackett Fischer.



Did you know that most health and lifestyle knowledge is worthless, and probably won’t have much impact on your health or lifespan?


IQ and Death
Trans Fat Hysteria and the Mystery of Heart Disease

On health and lifestyle, there is a lot of nonsense fluff on the matter of obesity. See:

Obesity Facts

And, there’s my critical look at mental health, and a misunderstanding of the role in human evolution in behavioral phenotypes, some of which are not valued by contemporary society

Features and Bugs

In the above post, I discuss homosexuality. The mainstream, accepted explanation for all manner of human behavioral variation, including individual and group differences, is some sort of social conditional or some sort of “environmental” effect. The one exception is sexual orientation, where we’re assured that it is 100% inborn and genetically inherited. Well, it turns out that that is not true. Indeed, this hard to reconcile with the fact that male twins are discordant for sexual orientation at least 75% of the time. See:

Greg Cochran’s “Gay Germ” Hypothesis – An Exercise in the Power of Germs

Also, you may want to see some of my other postings, like on the facts that “Ethnic Genetic Interests” Do Not Exist (Neither Does Group Selection) or about on the non-existence of free will:

No, You Don’t Have Free Will, and This Is Why

Or my post on the heritability (and hence intractability) of religious belief:

The Atheist Narrative

My 23andMe Results

Here the long-awaited results. Pretty much as expected, with no major surprises. About 2/3rds Black, 1/4 White, 1/12th Asian. The only unexpected things are in my Asian ancestry. Apparently, contrary to what I have been told, I have no South Asian ancestry. Also, of my East Asian ancestry, half appears to be Southeast Asian, rather than Chinese. My Chinese component is relatively small.

Also, my paternal haplogroup is G-M342.

My maternal haplogroup is L2a-d.
