First of all, I've updated my earlier posting Genes, Climate, and Even More Maps of the American Nations. I've included a few more maps, including a map of the American Nations superimposed on average annual precipitation: Go check it out! Second, here's my occasional periodic F.U. to the more vile White Nationalist elements out there.... Read More

Updated, 9/11/15 9/4/15. See below! Throughout this blog, I've talked a lot about the American Nations – a concept, based on a book by Colin Woodard, that North America is divided into several ethno-cultural-political regional "nations". These nations are distributed approximately as shown above. The empirical bases of the existence of these ethno-cultural entities has... Read More

One of the key points I've tried to stress on this blog is that micro-scale population structure – that is, fine genetic variation across populations can have a substantial impact on societal characteristics. We aren't just talking about continental racial variation. We aren't even talking just about ethnic variation. Sorting within an ethnic groups can... 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

With the recent spate of mass shootings, (at least four high-profile incidents occurring in the U.S. and Canada in the last two weeks), the issues of guns and violence inevitably come up. Naturally, the politically correct wisdom, which is founded on the blank slate (or at least, a bare slate), wants to blame these events... Read More

I have recently updated two key posts, my post More Behavioral Genetic Facts and More Maps of the American Nations. In More Behavioral Genetic Facts, I have expanded on an analysis on the meta-analysis of the heritability of criminality. This meta-analysis, a seminal work, represents the single best treatment of what we know of the... Read More

To the same scale...Let's look at the genetic differences on that scale...And for that matter, to the same scale as the previous map... (from M.G., see also Oh for a new risorgimento)And the differences in little old Britain gave us this:(See my preceding post, More Maps of the American Nations.)I'm just sayin'...See also (via Peter...

Post updated, 6/10/14. See below! As we saw previously (see My Most Read Posts), my post Maps of the American Nations is the single most popular post so far here on my blog. Americans all over are supremely interested in both their origins and the reasons for the cultural quirks of the different American regions.... 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

In the wake of the recent snow storm in the Deep South, The Atlantic recently released an article with a map made by Reddit user Alexandr Trubetskoy with the typical amount of snowfall it takes to cancel schools in the different counties across America. Since I couldn't resist, I thought I'd put Colin Woodard's American... Read More

This past summer my wife and I ventured through Eastern New England/Yankeedom (a.k.a., the Canadian Maritimes), and it involved a trip through the remnant of the French colony of Acadia, which in actuality is quite alive and well. In my final post of 2013, I will discuss these fascinating people. Acadia was the French colony... Read More

Edit, 4/16/14: Post updated, see below! I wanted to feature two new versions of Colin Woodard's map of the American Nations that I have created. For reference, here is Woodard's map: We know we can split the cultural and political behaviors (and many other aspects) of the United States and Canada according to these maps... Read More

We are familiar with Colin Woodard's map of the American nations: Especially their divisions in the United States. Now, for completeness sake, here they are for Canada (based on a map from Wikipedia): Many of the nations that make up the United States continue into Canada. In many ways, Canada is essentially the U.S. without... Read More

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

Colin Woodard's book, American Nations: A History of the Eleven Rival Regional Cultures of North America, is currently generating a lot of buzz. This is, in good part, thanks to an article that appeared in Tufts Magazine in which Woodard describes his work. Like David Hackett Fischer's Albion's Seed: Four British Folkways in America before...

Another map of the American nations: This is where the states stand on Obamacare's expansion of Medicaid. As you can see, it's far from universally embraced. Now let's compare that to this map: And for that matter, this map: Most of the usual suspects. Most prominent among those who reject the Medicaid expansion are those... Read More

In his most recent post, Greg Cochran quipped that since corporal punishment is a quiet issue these days, it likely works. EDIT: That is, it works in keeping kids in line at school, and only that. Needless to say, the map of states with legal corporal punishment in schools follows the Map of the American... Read More

Scientist/historian Peter Turchin (who was recently in the news for his model which describes the evolution of human civilization over the past few millennia) previously claimed that the United States is due for some sort of upheaval in the coming years – based on his study of historical cycles (cliodynamics), as previously discussed in my...

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...

Continuing my series on the American nations (see also A Tentative Ranking of the Clannishness of the “Founding Fathers�; Flags of the American Nations; Sound Familiar?), I take a look at the Cavaliers. The founders of the U.S. Tidewater and Deep South were people of noble blood that originated primarily from southwestern England, in an... Read More

My previous two posts featured some of the flags – assigned by me – of the various "nations" of North America, as described by Colin Woodard, and as derived from David Hackett Fischer. Inspired by the Bloomberg map of the American nations, where Woodard assigned a flag to each nation, I thought I'd make my... Read More
