What does it take to make a nation great? What makes a country a great place to live, a healthy society, and a bastion of stability? Various theories and ideas have been put forward, and I think they are all pretty much bunk. I think we can apply a little reductionism here, and conclude that... Read More

Unlike many commenters in this space, I don't particularly lament the secular rise of "universalism" that has occurred in Northwestern European societies (and their derivatives). Indeed, as a Black man, this is especially important to me. Without universalism, slavery may never have ended in the West. Without universalism, my family may never have been able... Read More

Post updated, 7/23/15. See below! At long last, I reach my 200th blog post. It's been a quite a ride! Blogging on human biodiversity – or simply humanity – has taught me a great deal. Since the start, I hoped that I could offer some meager contribution to mankind with this blog. I will continue... Read More

It's been nearly three years since the JayMan has been chugging away on the innerwebs about all this heritable biological impact on human behavior and society. I thought I would leave a quick snapshot of my most time-honored posts here at JayMan's blog. Now this is only for its life on Wordpress. For about the... Read More

Post updated, 9/14/14 6/5/14. See below! In my earlier post on Gregory Clark's work, The Son Becomes The Father, I laid bare the case for the known high heritability of human behavioral traits (including values and attitudes) and life outcomes. As well, equally important, I illustrated the complete absence of shared environment influences on these... Read More

HBD Chick's hypothesis – that long-term mating patterns – specifically, the degree of cousin marriage historically practiced by people influences the selective pressures those people experience, pushing them, over time, towards either clannishness (in the case of long-term inbreeding) or individualism and civic-minded (in the case of long-term outbreeding) – explains a great many things....

I may have to make "misdreavus" a co-blogger here at some point, considering how I quote him here. But, in defending HBD (Human BioDiversity), he has made a nice basic summary of the reasons why we believe in HBD (that is, overwhelming evidence). This was all in response to social anthropology scholar A. J. West,... Read More

Post updated, 9/13/14. See below! I haven't always made it explicit, but some of you might gather that I am rather hard on most "environmental" explanations. You have inferred correctly. The reason? Several, which I'll review here. The biggest of these? There is no good evidence for the vast majority of them. That's right, there... Read More

Updated, 10/17/15. See below! In this post, I will review Gregory Cochran's "gay germ" hypothesis. I wanted to make an index of Cochran's posts from his and Henry Harpending's blog West Hunter that discuss it. These posts don't seem to all show up under the "Homosexuality" category there, and I wanted links to them to... Read More

Go check out this fantastic post by HBD Chick on HBD and the motivations behind believers and detractors: you and me and hbd | hbd* chick now, i am the LAST person who should criticize anybody for obsessing about any one thing (see: most of this blog), but i’m going to any

Across the United States, there is a general pattern – at least among Whites – of urban dwellers tending to be more liberal and rural dwellers tending to be more conservative. Indeed, this pattern is so pronounced that Steve Sailer managed to produce a now well-known (at least in the HBD-sphere) hypothesis of White American... Read More

My earlier post, Mapping the Road to American Disunion, discussed the apparent high likelihood of increased social and political unrest in America in the coming years – a process which, with the ongoing partisan stand-off in Washington, might well be under way. This was based on the work of Peter Turchin and his field cliodynamics.... Read More

Slate recently featured an article written by Roy F. Baumeister, Do You Really Have Free Will? In it, he claims that human do indeed have free will, something that regular readers will know that I have emphatically argued against. Baumeister doesn't make any supernatural appeals in this article; he does not appeal to some sort... Read More

HBD Chick and I talk about how rates of historic inbreeding have had an important impact on the selective pressures acting on the traits of various peoples living today. We have often used Europe and the Middle East as examples of this, because strong regional variations in historic rates of inbreeding exist in those places.... Read More

Edited, 4/11/15 3/17/14. See below! Blogger "Agnostic" over at Dusk in Autumn has a post up about the regional variation in Germany (Oktoberfest, lederhosen, dirndls and Germany's cultural fault-line). As I've noted in my posts on the American nations (most recently here, see the category here), Germany has been one of the most important countries... Read More

Continuing my on-going series on the regional differences – genetic regional differences – between the different Euro-Americans in the United States and Canada, here I will present a series of maps demonstrating some of the evidence for the existence and significance of these differences, beyond the historical circumstances explored by David Hackett Fischer (DHF) in...

Post updated, 1/14/15. See below! Let me start by once again giving the disclaimer that I am an unapologetic atheist. Of course, I would conclude that being an atheist is the only natural position one can have if one is being a true scientist. Now, that said, I realize that I am only able to... Read More

Edit 2/24/14 [Post updated, see below] Edit 7/20/13: [Post updated as per HBD Chick's comment. See below] The European colonists (mostly British, French, and Germans, with a smattering of other groups) who first settled North America brought with them their distinct "cultural" features that laid the foundation for the persistent regional differences across the U.S....

Readers here will recall my recital of Greg Cochran's hypothesis that obligate male homosexuality is caused by a pathogenic agent, likely a virus (please see 100 Blog Posts – A Reflection on HBD Blogging And What Lies Ahead: Homosexuality (the “gay germ” hypothesis)). This is by far the most likely explanation for male homosexuality (see... Read More

Post Updated, 10/9/13. See below! Readers coming to my blog from The Atlantic article "The Mystery of Why Portugal Is So Doomed" saw my comment there directing you to my earlier post "A Tale of Two Maps." Matthew O'Brien over at The Atlantic seemed to indicate the poor economic situation in Portugal was somehow mysterious.... Read More

This is my 100th blog post. Upon reaching this milestone, I thought that this would be a great time to take moment to look back at my experience as a blogger in Human BioDiversity (HBD) and share my thoughts on the things to come. 1. The Beginning 2. Fertility 3. Immigration and the economy 4.... Read More
