    I am a Geologist and Palaentologist. I find your views fascinating. The trouble is that I am also German. We had somebody in the past who come to early conclusions about ongoing evolution and tried to take this into his own hands.
    Europe is wedged together by colliding Microcontinents. Spain run into France, Italy into Bavaria, everything in the Permian province of Russia. Then we merged and split twice with the Americas. That all is quite unique on a worldwide scale.
    And we also seem to have the most astonishing mixing of roaming human groups going on. Can this be a coincidence? Or should one also look into the relation of Geology to all this? And I do not mean Geomorphology (Geography) and not Climate (or only the Geology driven aspect, like orogenic events blocking of air streams).
    In particular Mr Wade forgets Geology. The sole reason that Great Britain was first in industrial revolution is rooted in Geology. They had iron and coal at the same spot. One shaft could dig out coal, the next one Iron. Germany was next in proximity (Ruhr valley to Salzgitter), Then comes France, then Italy… There you have your ranking. (I need to write to Mr Wade one time…)
    Again, this is Geology and needs a place in the analyses of human evolution.

    I’m a mathematician with extremely varied professional experience and particular expertise in logic, game theory, and statistics. I’m interested in several mysteries of genomics and anthropology. The one I’d most like you to address is what I call the haploid number puzzle–how did closely related species with differing numbers of chromosomes diverge? It’s hard to see how such a speciation could have happened without a much more severe genetic bottleneck than DNA sequencing indicates could have occurred.

    • Polymath says:

      Oops, my screen name got lost somehow before, I’m the mathematician whose post came out as from “anonymous”. I understand that Henry doesn’t have as much time to blog here as Greg, but I’d like to see him at least comment more!

      • Peter Lund says:

        The ancestral karyotype of the house mouse (Mus musculus) consists of 40 acrocentric chromosomes, but numerous races exist within the domesticus subspecies characterized by different metacentric chromosomes formed by the joining at the centromere of two acrocentrics. An exemplary case is present on the island of Madeira where six highly divergent chromosomal races have accumulated different combinations of 20 metacentrics in 500-1000 years.”

    • Peter Lund says:

      The tentacle monster from Minnesota wrote a bit about that. When he stays off the political stuff and sticks to the biology he can be quite readable. That was especially true in the early days, before he gathered his rabid cult followers.

      I don’t think he ever discussed the surprising diversity that somehow manages to survive a chromosome number change, though.

      • Polymath says:

        Everything he said, I’d figured out for myself, but I haven’t seen a good explanation of how a small subpopulation with a different chromosome number 2N+/-2 that has reduced fertility when combining with the co-habitating main population with chromosome number 2N or the hybrid population with chromosome number 2N+/-1 can avoid extinction unless there happens to be a habitat separation which by chance creates a subgroup with a preponderance of the 2N+/-2 population. This seems extremely unlikely unless the genetic bottleneck involved is very narrow, even if you assume a promiscuous species and a lucky trait on the newly split/fused chromosome that allows members of the subpopulation to identify each other.

  3. MawBTS says:

    I read this blog because it’s an incredible source of insight porn – I’ve learned about things like the breeder’s equation, contagious tumors, gay germ theory, and more.

    It also has a comment section of unusually high quality – probably due to a policy of banning polite but stupid people.

    Suggestions, too – I’ll read ’em, although I make no promises.

    An occasional link dump, so we can see what you’re reading.

    More stories from Greg’s past, and Henry’s time in Africa.

    An occasional “ask Greg/Henry questions” post. It would cut down on the number of people who barge into random posts asking “what do you think of X paper? / What do you think of X hypothesis? / Does my ass look fat in these jeans?” etc.

  4. SeanV says:

    Well I’d certainly be interested in you guys developing that policy idea for child benefits payments being paid to dad’s. I mean that was one aspect of it at least – I’m sure there was more.
    In general I suppose econ/pol implications from all this anthropology would be interesting – at least as speculations.
    That said – be careful what you wish for – politicising this excellent blog/resource would perhaps be a place you don’t want to go to.
    Either way, keep it up guys. Happy New Year!

  5. Well, I’m a housewife with multiple kids and an educational background in STEM. I’ve been reading your blog for at least a couple of years, probably since Amazon recommended the 10,000 Year Explosion for me.
    I appreciate the way you guys bring insights (and common sense) from multiple different disciplines/points of view. I always learn something new from your posts.
    I don’t have any particular requests; just keep doing what you do. 🙂

  6. I’m a web developer, and I’ve also been reading the blog since I read the 10,000 year explosion. Six kids and an interest in HBD and your thoughts on the matter. I’d second the recommendations above, but what I’ve actually enjoyed most is the more science-fictional speculations. That’s just fun.

    Keep up the good work, and a happy new year to you both.

  7. JayMan says:

    What a great idea for an end-of-year post.

    Would it be out-of-place to just link my “About Me” page here? 🙂

    I would say that this blog is THE primary HBD(-esque) blog. I wouldn’t say top of the list, only because it’s probably not where novices should start (The 10,000 Year Explosion is where they should), but I think this place should be thought of as “the final word” – or, more accurately, the reality check.

    I don’t have any specific suggestions at the moment other than to keep on keepin’ on. Two important functions of this blog is to put the kibosh on popular nonsense and to explore mysteries in novel ways, and you’ve been doing that. Should something scream for debunking/investigation, I’ll be sure to make a note.

  8. Don’t pay too much attention to readers. Write what you think.

    • AnonymousCoward says:

      The exception perhaps being when you insult and ban people, that’s great.

    • AnonymousCoward says:

      An exception being, please do continue to insult and ban those who post nonsense. Not only is it entertaining, but I feel that it is perhaps one of the most important ways in which you educate.

    • maciano says:

      36, Dutch male, MBA.

      HBD started to interest me when I worked as a demographer in a thinktank earlier in my life; all my colleagues seemed clueless about the implications. Their cluelessness made me search for like-minded people on the net.

      I’d like this blog to stay as it is.

      That said, I’m curious what intellectuals, country & political systems Cochran admires or who influenced his ideas.

  9. Handle says:

    STEM-inclined individual who took a wrong turn and ended up in the law, and in the government. (I know, I know).

    I’d like to respectfully request a series of posts which could bring some clarity to the confusion which reigns in discussions of theories related to group selection.

    • peppermint says:

      It’s a meme in much of the Internet to call your enemies k selected or R selected, because one of those sounds freedomistic or whatever, it made more sense when I heard it from liberals but I hear it more often from conservatives like it’s some kind of secret knowledge the liberals wouldn’t dare talk about.

      I’m guessing that Whites are supposed to have as many children as they can reasonably expect to be able to get in a position to reproduce, while Blacks are supposed to have as many children as possible, and political persuasion has nothing to do with basic reproductive strategy except to the extant that political persuasion is a direct result of reproductive strategy, since reproductive strategy is the most important thing.

      (I’m also guessing that they gay germ theory is meaningless because gays, defined as broken men who wouldn’t have sex with a woman if she was available, do not exist, but, rather, all gays are bi, where bi means following a promiscuous reproductive strategy. Also I expect that most transgender men are like the transgender male salmon who want to sneak onto the egg pile when the normie male salmon are fighting each other. Reproductive strategy is üeber älles, and all this ideological individualism is just lies to get in womens’ pants and the government’s pocketbook, and yes, saying you’re bi does work to get in womens’ pants, I’ve done it)

    • J says:

      I second this call for some clarification of “group selection”, in particular why if there is no “brotherhood of warm blood”, people are willing to sacrifice themselves for the tribe, nation or race? Is it simply a morbid “mind virus” like religion can be?

  10. Tolmides says:

    After a misspent youth, in which my personal addictions eventually and inevitably spilled over into genuine anti-social acts, I was exiled by the Time Lords to the section of history that we refer to in the year 3743 as “the punishment century.”

    I would like to see daily posts!

  11. LemmusLemmus says:

    Me: Ph.D. in sociology, work in a research institute (with no links to a university).

    I read the blog for biologically-informed, unsentimental perspectives on social issues. And the swearing. As I have no background in the life sciences, some of the more technical stuff is above my head.

    I second Handle’s request for something regarding group selection.

  12. another fred says:

    69 yo engineer. Started school with an interest in anthropology/ethology but let the need to make a living shift me to engineering (plus the fact that I really didn’t like the way the leftist/blank slaters were dominating anthro in the ’60s).

    I like your insights into the finer details of science/life/history and the links, especially the links. I probably should have stuck it out in anthro/ethology. Engineering is mostly drudgery to me, but it’s a living.

  13. drstevelaw says:

    61 year old dentist. After Sailer recommended the “10,000 year explosion”, I started reading for insight into the human condition regarding societal observations that I made and everyone knows but we are not allowed to acknowledge or speak about. Plus Greg C has titanium stones with some of his comments.

  14. DdR says:

    Hopefully you won’t be upset, but I was hoping you could dumb it down a bit.

    36-year-old, work in finance in NYC, just married and looking to start a family. I took biology/chemistry in high school. I get the gist of what you’re saying most times, but a lot of stuff flies over my head. Maybe hotlink more of your sentences to papers and/or Wikipedia entries, where the unlearned could go learn more what you’re talking about? Or maybe use more analogies?

    I really like how you deal with trolls, although maybe you could demean them via a new post on why they are completely wrong and not just shut them down in the comments section.

    I also found your insights on aging really intriguing. Why no one is really dedicating resources to the problem but expending a huge amount on cancer or other medical research, when most chronic diseases are diseases of an aging body?

    • Frau Katze says:

      Rather than “dumbing it down” a list of good books for background reading would be serve the same purpose (on a separate page, not a blog post which will soon get lost).

      I majored in Math/Physics but ignored biology altogether. (I didn’t like dissecting frogs). I’ve looked a few times for a good beginner’s book but there are so many!

    • peppermint says:

      » why do 24 year old women go on parades and people spend money for raising awareness of breath cancer, but no one really seems to do anything about the actual problems

      remember when liberal academics in the ’20s said that the future will be a scientifically managed democracy in which from each according to his abilities to each according to his needs?

      Igor Shafarevich couldn’t figure out why people ever thought that, but today’s cutting edge social science research, not conducted in the university of course, suggests that it’s mainly about social signaling.

      Social signaling probably occurs among vampire bat colonies as well as in human cities, but we have large-scale civilizations in which resources are anonymously transferred through a number of third parties from the people who build to the people who bullshit.

  15. IC says:

    As busy professional with small corporation to look over, I occasionally read blogs out of intellectual curiosity. Like some else suggested, blog about what you think important, not what reader think. As scientist, social validation or social approval is last thing you care. Evidences are the only things matter.

  16. Thomas says:

    Your candor is refreshing. (A cliche, but true.)

  17. Johnny says:

    Since you ask, I’m a 25-year-old (single, no kids) attending college with an English Lit major and a Comp Sci minor and working tech support in a call center. I read your blog because I think it’s important to stay up-to-date on the opinions of those with whom you disagree. To that end, I try to have five or six blogs I follow but disagree with, to get a more complete view of the range of opinions and arguments I might not get if I just stuck to what I like.

  18. Jacob says:

    I majored in biology and taught middle and high school science for ten years, then went back to grad school and now evaluate education and early childhood programs, mostly for the feds (as you remarked a few weeks back, people like me are the problem.) I guess I’ve been looking for a bridge between biology and the social sciences for years now, as well as being personally interested in topics like ancient history and the development of language.

    No suggestions. Keep it up.

  19. Gabriel Lombardi says:

    I’m a laser physicist. I was in college when the controversy erupted over Arthur Jensen’s paper on intelligence; witnessed the vitriolic, unscientific response. Promptly forgot about it, only to see history rhyme when Herrnstein and Murray published The Bell Curve. Hmmm… maybe there’s something interesting here. But my gateway drug into human biodiversity was The 10,000 Year Explosion, from which came a flood of new ideas that contradicted what I had previously learned about human evolution. Next came The Blank Slate (Steven Pinker) – more insights that upended my beliefs! After that, JayMan’s blog, hbd chick, Henry Harpending’s lectures on YouTube, the paper on Ashkenazi intelligence.

    No suggestions except to continue with the fearless truth-telling. Maybe someday it will sink into the brains of the politically correct. Otherwise, we’re doomed. We’re probably doomed anyway.


    • another fred says:

      Hopefully we are just doomed to keep evolving. The current dysgenic trends will not survive the coming collision with reality. If we can just avoid an all-out nuclear exchange between major powers the future will be quite bright for those who make it through the bottleneck.

      • melendwyr says:

        ‘Dysgenic’ breeding is an example of evolution. As water seeks the lowest level, biological populations meet the minimum requirements for persistence of survival traits.

        • another fred says:

          Dysgenic breeding can also occur when selection pressure is artificially and temporarily removed.

          • melendwyr says:

            Quite right. But the ‘artifically’ is too limiting – any time a selection pressure is eased, populations tend to express the traits that pressure had been controlling. This can be ‘dysgenic’ in the long-term, and it’s still evolution.

    • IC says:

      Evolution itself does not give a shit about right or wrong. Only final judgment is survival. If you fit, you survive. If you don’t, you are doomed. In eyes of mother nature, we are no better than cockroach.

      So don’t be so sentimental

    • Jim says:

      The effect of empirical evidence may cause some of the more moderate people on the left to modify their beliefs but many of them will simply become more extreme and delusional. Many of them already make Mao Tse-tung look sensible.

  20. someonecheeky says:

    I have a philosophy background and work in Software. If you took a few years of symbolic logic, programming, software design is quite easy to pick up.

    My subscription to your blog started after reading your book. I have an interest in all things epistemological, blank-slatism has always been a pet-peeve of mine. Evo-psyh, Evo-Bio also interests me from a similar perspective how can we know certain things, how do we make claims we can prove.

    I’ve kept reading your blog because you’ve had interesting insights on problems I’ve often thought about. Although I do think your gay germ theory is wrong.

    There are many more gay men then woman. Thus is more likely the consequence of nature taking more risks with men, have more men at the tails of the distribution. Thus for a man having a feminine face like mine, or like Leonardo DiCapro is advantageous, but it’s a risky strategy, and if you go to far you end up on the tail, and gay. Since nature takes fewer chances with woman, their are less lesbians.

  21. jayinhawaii says:

    I am a retired systems analyst. I am interested in “inbreeding” (e.g., first cousin marriage) and how it causes one population’s behavior to differ from another.

  22. Life is good, because I am not worn out and get to work when I feel like it. It seems obvious to me that we are fast heading to a singularity where we can fix stupid. Just last week this paper came out, . This paper, if true, is what I am talking about. The scientists are going to crack the code, they are going to find out the gene networks that lead to high intelligence or are not optimal and make a human dead average.

    God damn, we live in interesting times. All this stuff is breaking loose now. Cochran is a lot more than an entertaining writer, he is a cutting edge theorist, he reads the latest scientific papers and keeps us peons updated on the latest breakthroughs and new possibilities.

    We are all hopelessly self centered, we look out from our eyes our whole life and rarely bother with caring about the big picture. It has only been half a billion years since evolution concocted a new sense. The eyeball made for a vastly different world, full of chasers and the chased, now the minds eye has evolved far enough so that we are just a generation or two away from manipulating human intelligence so that we can hand out mind glasses to the next generation.

    And all this will make for grand entertainment. We will get to see the look on the dumbshits faces when they realize not only is evolution real, they are next. We will all be dead when this new technology transports us to a world where genius is average, but it is coming and it is coming fast. What we can do is enjoy the show and thank Mr Cochran for giving us front row seats.

ADHD tendencies pushed me into physical labor, discovered that cutting the roofs of millions dollar houses satisfied my needy brain so I did that until the body said cut it out.

  23. James Miller says:

    I’m an academic economist and the author of Singularity Rising. I would love to read more on your views concerning enhancing human intelligence. Do you think CRISPR will soon let someone create babies that grow up to be super-geniuses? What’s the time frame?

  24. RCB says:

    Time to shed the anonymity. I’m Ryan Baldini – male, 28, CA. Recently left the world of academia and evolutionary anthropology to make money in the general modeling/data scientist world.

    I come here because Greg seems to be unusually smart and creative – good at connecting dots. Rather than trying to describe what content I like, I’ll link to one of my favorite past posts:

    Still waiting on the Cochran Curriculum.

  25. Little spoon says:

    I’m 33, I live in nyc and I work in finance lite (Cush job with high pay and little real effort expected). Can we do more posts about theory? Like why is epicen epigenetics a logical problem? (Or is it a lack of evidence problem?) I’d like more systems biology theory, especially with topics involving statistical reasoning.

    I studied cog sci in undergrad, I’m a South Indian Brahmin and I like to sing.

  26. Alex says:

    I’m a tutor for university level math, physics and electrical engineering. I’m a longtime lurker on this blog, and according to my dad, a distant relative of Dr. Harpending.

    I enjoyed the10,000 year explosion and recommend it to everyone I can.

    I can’t get enough of posts detailing ancient population movements, especially the PIE expansion, and also the sci-fi premises on what would happen if we made everybody more intelligent.

    I have imagined an alien race with tens of millions of years of genetic engineering and selective breeding and some of the things I’ve read here made me realize that I drastically underestimated the things such a race could do.

    Keep up the good work and happy New year!

    Background in tech, originally math.

    The posts on messy biological are the most enjoyable, e.g. Mycoplasma pulmonis.

    I’ve read the 10’000 year explosion after hearing about it in the daily shoah.

    I strongly like debunking of biased “science”.

  29. Deckin says:

    Philosopher by training and manage to make living doing it. Had to write a review of a book on race (had never thought much about it before and had the usual ‘skin deep’ view). In researching for the review I had my eyes opened at GNXP and have been a learning lurker since. Strangely, this opening also converted me to Bayesianism in both Stats and Phil of Science, both of which I’ve put to use in my day job. My Math training ended with second semester Calc so much of what happens here sends me scurrying to reference material; but I have learned so much. Thanks and keep up the good work.

  30. STEM Finance says:

    c. 35 year old, engineering background with Phd who now works in investment banking in NYC (sold out for the money). Originally a Slav from Eastern Europe. I read this blog because much like iSteve I feel like you are focused on truth above all else and this is interesting to me. Double interesting because I view the hypocrisy of faux liberal ibankers who push all of the latest doublethink but when it comes to their own kids act like HBD was the gospel. Like many others here I am always keen to hear when you recommend a good book to read and have gone through many books on your past reading lists and enjoyed them.

  31. Anonymous says:

    25-year-old underemployed late-bloomer/autodidact, degree in physics, interested in psychology, cognition, computation, philosophy, anthropology, all sorts of stuff. I’ve been exposed to a lot of cool ideas on this blog, but mostly I just like being able to hear a smart old dude saying un-PC curmudgeonly things. It makes the current zeitgeist seem a little less overbearing.

  32. teageegeepea says:

    I’m a software developer in my late twenties, in Chicago. I’ve been reading Cochran since the GNXP days. I don’t follow many blogs as closely as I used to, but this is one where pretty much any additional content is quite welcome.

  33. brendan says:

    I’m a 30 year old stock picker.

    The main reason I read Greg is because he’s right about everything. I’m young and humble enough that I’ve got a list of a half dozen guys, a list which Greg tops, who I’m basically not willing to disagree with. If I can’t entirely follow the reasoning, I’m reminded of a lot of school/life advice that makes more sense at 30 than it did at 20. “I wish I knew then what I know now”, etc. I’ll cheat off Greg’s answers, where necessary (it’s a big world), until I can do the problem myself.

    Another reason is the style of problem solving, i.e. that one about rail gauge, WW2, spherical cows, etc. And everything you’ve ever written on Iraq. Analytical style is such a tacit thing that it’s hard to describe exactly what it is – but I want to emulate it.

    And of course the beautiful scorn.

    • ursiform says:

      It’s good to identify sources that are reliable, as well as those that aren’t. But you should never assume that everything one person says is correct. You should critically evaluate everything you read. Even when written by Greg. I think even Greg would agree with that.

      • brendan says:

        I agree in principle but in practice people are way to willing to deviate from people (or institutions like stock/prediction markets) that have proven their accuracy.

        When Greg (or someone like robin hanson or david friedman) makes a claim that surprises me, that I wouldn’t have agreed with before, I like to try the idea on for awhile, search for and notice relevant evidence, give it time. Often the thing becomes obvious in retrospect, working backwards from the answer to the evidence.

        It’s much like taking asset price movements seriously when you’re trying to explain economic events, i.e. if Obamacare was gonna wreck the economy then why’d the stock market brush off the period where the odds of implementation changed so much?

        I don’t want a worldview that conflicts frequently and in important ways w/ things that are smarter than me.

        Greg, my favorite posts, the ones I’d like more of, are the ones about problem solving in general, i.e. the thick/thin talk, Wizard War, the stuff you’ve had to say about how just plain knowing lots of stuff is underrated; also intrigued by your recommendation of Polya’s book on problem solving, interested in your thoughts on that, etc.

    68 yo, swm; ba in physics/math, ph.d. in demography; work experience all over the map including survey research, software development, non-linear dynamic models, criminology, epidemiology, national security policy, et al. I enjoy the eclecticism and rigor of your analyses (a very rare combination) and its constructive iconoclasticism. I also enjoy your acerbic wit and unwillingness to suffer fools gladly, although I’ve been scorched by both on one or two occasions. I am grateful for the existence, thoughts and writings of you and your colleague. Please continue as you have. One minor wish is that you might promote material on your blog more often and more regularly; but not if this might somehow interfere with the uniformly high quality of what you’ve produced to date.

  36. Sid says:

    Just turned 27.

    Way back in Summer 2005, I read about the authors’ article about the evolution of Ashkenazi intelligence. The article blew away everything I thought I knew. I’ve been into HBD ever since, though I’ve never told anyone who knows me in person about what I think about the matter.

    • Jim says:

      It amazes me that anyone who lived in an area with a substantial number of Ashkenazi Jews wouldn’t notice their relatively high average intelligence without having it to be pointed out to him.

    I’m a freelance front-end web developer. I used to post here under my real name, but I’m looking for work and can’t risk having my name pop up for thought crime.

    When I was in college, I double-majored in physics & math, but I dropped out to join the priesthood. I finished all of my classes in seminary before being rejected for ordination. I was told that I was better suited for research.

    I learned of you through Steve Sailer’s weblog. I read you because you seem to actually think things through and to know a thing or two about a thing or two (imagine that!).

  38. jasonbayz says:

    Undergrad, majoring in computer science. I was unusually interested in politics, economics, and the like in high school and would spend my free time and class time(I had a smartphone, makes class a lot less boring) surfing the web and reading stuff. Eventually I found the alt-right/HBDsphere.

  39. anomaly says:

    Lets see… Thanks to pissing away a perfectly good full scholarship in favor of a technical education .I had my reasons, no phD. Im a stylist in the Atl area. You may have seen me on Bravo networks, Tabitha’s Salon Takeover, but since i was trying not to be seen, as in (nothin to see here folks..Move along) I doubt i made an impression. I love Gerald Schroeder, and after reading some of his books, (the hidden face of god in particular) Ive been very interested in genetic mutation from a scientific point of view as well as a spirtiual one. Maybe God gave humans sickle cell to save them… Since its an ecosystem its not as easy as killing all the mosquitos?? Ive also been curious about the genes i carry. There’s alot of research on the horrific outcome of two copies but not much information otherwise. I cant wear contacts because I have enlarged foveas’ and cant see indoors with them on. I also have a very slight enzyme imbalance that would go unnoticed but made storing breastmilk for more than a few minutes a science project (it Involved heating it). Im facinated by the idea that since theres no fitness advantage to homosexuality youre probably on to something. Not very socially popular but maybe in a few years that and autism will probably be linked to gut bacteria either in utero or early infancy. Fecal transplant cures for everyone!! Ha!

    54, nurse. I like the wide variety of topics, with angles I hadn’t considered before. I’d like to see more frequent posting. Keep the comment section well-moderated and ban trolls. Your comment section is one reason I read here.

  42. Retired aerospace engineer, 67, outside LA. A bit more detail would be nice when you shoot down other theories/opinions–it may be obvious to you, but more information is better. When your posts are often brief, they don’t provide much education

      38-year-old without a job agreeing with you. I was originally attracted to the blog by the willingness to call a spade a spade, but after the 50th “shooting down” you start to feel that the guy likes expressing disdain more than being correct.

  43. 60, physicist, curious about many things. I’ve found some things here I didn’t know I didn’t know, and therefore decline to make suggestions.

    32 year old in NYC, social sciences and humanities (and left-wing) background, Came upon this, 10k, and related blogs a couple years ago, and a decade of blank slatism collapsed in short order, with Greg playing an outsize role in the corruption.

Happy New Year, good health, and thanks for doing what you do.

    My questions:

    When we know the N (Razib says 10) thousand SNPs for IQ differences how much will embryo selection between 6 or 12 (making up numbers) embryos with IVF boost average offspring IQ?
    How hard is the problem of finding the N thousand IQ SNPs and other genetic variants? 5 years? 10 years? DNA sequencing costs have plummeted 4 orders of magnitude in less than 10 years.
    Do you think large copy variation plays a substantial role in causing IQ differences?
    Will the 3-D shape of chromosomes (and histones and other such) prevent CRISPR-Cas9 from being used to edit some sections of human chromosomes?
    When a large fraction of the genetic variants for cognition and behavior become known will this shift the Overton Window on any policy issues? Which ones? On which policies will America remain as stupid as ever? Will government policies become even dumber on some issues once the truth is known at the genetic sequence level?
    Do you expect genetic variants for cognition will be used for job screening in America? China? Other places?
    Will the human race fork as a result of genetic engineering of offspring?
    Jonathan Haidt has used the phrase “moralistic death spiral” on Twitter to refer to what is happening with political correctness in academia. Will progress in research on human nature eventually be entirely blocked by this problem in the United States?

My wife is from Alabama, and went to Ann Arbor, so my life is going to get interesting in about two minutes.

    I also look forward for any insight you might shed on the group-selection-as-an-emergent-property thing. Please keep up the fascinating work!

  51. expeedee says:

    I am a retired San Francisco police officer (inspector) who spent over thirty years observing and trying to understand human behavior. I dismissed may of the things I learned in college, specifically the sociological/psychological explanations of human behavior and was drawn to the study of genetics as a possible answer. I picked up Steven Pinkers “The Blank Slate” about twelve years ago and that changed everything. Next, of course, I had to read Edward Wilson I now have a library of books on genetics, evolutionary psychology and HBD, which leads into the whole issue of determinism. I read “The 10,000 Year Explosion” and learned much and continue to read your blog. I’m currently reading about epigenetics and find the disease implications interesting, and I enjoy you views on this controversial subject.

      Since you are interested in crime, are you aware of Beaver, et al.?

      • expeedee says:

        Thank you for the information. I’ve read about MAOA alleles and their connection to violent behavior before but have not read this specific study. Thanks.
        There are a multitude of factors involved in crime and social disorder and I am particularly interested in the biological i.e. heritable factors in altruism, impulse control, mirror neurons, substance abuse, etc. Cops tend to be empiricists and certainly not shy to challenge liberal orthodoxy when it comes to crime and social disorder. Consequently, I abandoned the notion of the environment being the sole cause of crime and disorder a long time ago.

  52. Grumpy Old Man says:

    I’m interested in your thoughts about how widespread adaptive polymorphisms are, related to behavior–schizophrenia, bipolar, and autism. We need pessimists and risk-takers, and these conditions may be the extreme recessive-like manifestations.

    I am Ph.D. in Human Geography (not physical, human) with long standing interests in urbanization and migration, including migrant self-help societies and human capital. At the moment I don’t work in academia, which gives me more time to read blogs.

    I probably found this blog from Steve Sailer’s work, or from someplace in the Steve-O-Sphere. I often suspect Sailer’s analysis suffers from an “omitted variables problem,” but no matter. As Linus Pauling said, “The way to have lots of good ideas is to have lots of ideas and throw the bad ones away.” Some people are best suited for careful empirical research, while others debunk or generate hypotheses. Bruce Charlton made a similar point: it is valuable to propose ideas, and our current society seems squeamish about doing so outside a certain (narrow?) range of beliefs. Mostly we are encouraged to be “Blank Slatists,” as Steven Pinker would put it.

    Your blog posts are provocative whether I agree with them or not–and much of the value of your blog comes from the comments. Imagine my surprise when I learned that a co-author of this blog is listed in “The Extremest Files” compiled by the Southern Poverty Law Center! I wonder–what does it take to get included in the “Extremist FIles”? Deleted from the list? Investigated but cleared of “extremist” tendencies?

    Your book Ten thousand year explosion I have browsed but not read with intense focus. I hope to get back to it this year and give it a more thorough reading. So many books, so little time.

I studied history and joined the foreign service in my early twenties. I spent many years employed by a well-known U.S. private foundation, working as a grant administrator in the fields of international public health, demographic social science research, and contraceptive development. My life’s work has centered on being a good wife and mother, not my official job. The older I get, the more I realize that this was, for me, a wise decision.

    I found this blog from Working in the government taught me that the larger the agency the less efficient the results, and surviving in the politically correct world of a private foundation where “diversity” is lauded except in crucial areas, such as political opinion, have given me a true appreciation for blogs such as this one which give even an ordinary housewife the opportunity to learn from intelligent people with wide-ranging and spanking new ideas and opinions. Many thanks for your blog, and for all your outstanding commenters.

    I attended a comprehensive ‘inner London’ high-school where non-Whites (mostly Muslim) made up ~ 60% of the pupils so I was an intuitive HBDer from the start. And then, when I was about 17, I discovered the whole HBD world on the internet and eventually came to read the 10,000 year explosion – and I’ve read my share of non-PC books by now (e.g. Lynn, Rushton etc) but still your book remains one of my favorites in the genre.

    Adding to James Miller and Randall Parker in requesting your commentary on the feasibility of IQ enhancing reproductive technologies (which, in my humble opinion, is likely the only way to reverse the global dysgenic trends conduced by the demographic transition). And finally, adding my thanks to many others here for doing what you guys do!

At times it’s a little hard to pick up on the implied messages in posts, but I appreciate the challenge and reading the comments usually allows me to get an idea of what you’re trying to get at.

    I am a semi-literate 66 year old Scotch-Irish redneck. I spent most of my life suffering from the Blank Slate/Noble Savage syndrome while having a wonderful life with wife, kids and grandkids. From an early age I have kept an eye on politics. It is impossible for me to have accumulated the hatred and contempt I have for politicians during one short lifetime; I had to have inherited some of it. I thought people smarter than me would be in leadership positions and would keep the venal and criminal under control and our country would muddle through. Ha!

    I have two daily struggles: keep my anti-intellectualism under control and remember that the commie solution of killing everybody that gets in the way is not a good thing.

    During the new year we need for you to consider offering some practical solutions to some of the problems that you are so good at identifying and explaining.

    My current interesting question is: Are males inherently more co-operative than females because of different behavioral selection pressures. Here I am thinking of male chimps co-operating to hunt monkeys etc.

    A subsidiary question is: Did the change of meaning of baring one’s teeth occur before serious language development?

    However, I would also be interest in why 10,000 seems to be a special number, as in, selection seems to find it difficult to reduce nasty things below about 1/10,000.

  62. IC says:

    Some many readers also appreciate high quality of comments on this blog. Some even come here for the comments section. The high commentary quality thanks to moderation of the blog owner, Gregory Cochran .

    He applies standard of scientific journal peer-review on comment section mostly. Many other bloggers were not able to do critical analysis on comments and could not differentiate critical opinions vs trolls. Some these bloggers moderation is close to coercion with personal insult. The problems of these bloggers mistake social approval (social validation) as proof of their own correctness . It is no difference from mafia boss who use shotgun to make everybody agree with him. However typical scientists only pay attention to whether objective evidence (like data, less degree anecdotes) agree with various hypothesis (idea, speculation etc.).

    People intuitively believe anyone with different opinion as idiot who actually might be way above our own intelligence (dunning kruger effect). Like I said before, you need leap of intelligence or faith to avoid this kind of egocentric point of view (like geocentrism, ethnocentrism or racism, many similar ideas). Unfortunately it takes intelligence to avoid dunning kruger effect. Some people are hopelessly (actually happily) trapped in their self-centered universe. Stupidity is indeed a bliss.

    • IC says:

      Additional point is that some blogs lack adequate moderation. Such bloggs become troll-heaven which actually discourage reasonable readers to visit or comment. Most trolls have some psychological or psychiatric issue who can not participate normal human interactions. If you ever did a medical residency in psychiatric ward, you know how hopeless these patients are to be reasoned with. Only option is to avoid them if possible.

      At other level, people understand others with similar mental ability. It is no surprise that most intellectuals befriend with other intellectuals beside social connection. If one is appreciated mostly by underclass, one is more likely one of them (politicians are exception because they are basically salesmen who will say any things to get social approval).

    • I have noticed that the comment section has become self policing. Before Cochran can tell someone that they are wrong other commentators do it. There isn’t a shrill rudeness that you find on other blogs just a factual correction. When someone is stubborn and verbose about their misguided opinions then it gets funny because Cochran really lets them have it.

I remember the protests against Vince Sarich when I was a student at Berkeley sparking my curiosity about HBD way back then. With no genetics/biology background, the fun part for me is treating posts and comments here as puzzles: I have to go learn new stuff to be able to comprehend them. My only request would be “don’t dumb it down,” but I can’t imagine any chance of that happening anyway.

    Early-fifties engineer (specializing in physical modeling and feedback control), in coastal SoCal. Having children jump-started an interest in genetics and how the brain works, which led me to Dawkins (The Selfish Gene and more recently, The Ancestor’s Tale) and Pinker (The Blank Slate is brilliant, and I also love his language books), HBD, and eventually this blog. Specific topics of interest are the genetics of behavior, human population origins, and human intelligence. I like the willingness of this blog to explore knowledge fearlessly, without concern to where it leads – the antithesis of odious political correctness.

Although plenty of posts go over my head with my very small formal STEM education, I read them all (and at least imagine I learn something). Got a few posts in, then went and bought 10K Year Explosion the next day. So many things make much more sense after reading this blog (and related books, etc).

    As for westhunt content: I vote for more of the same.

    However, I’m also curious whether Greg has any particular thoughts about the Iran nuclear deal. It’s an important topic on which I don’t feel qualified to have an opinion.

    Also, if it’s not too personal, I’m curious to hear more about Greg’s religious views. He’s a Christian, if I’m not mistaken, which is unusual, but not unheard of (Fisher, Dobzhansky, Price) among evolutionary types.

    I’m 76, female (pretty clear “male” is the unmarked gender in this neighborhood), former journalist (mostly retired) and also former math professor (long, long ago). I have been reading Cochran, with delight, since the Ashkenazi paper, and I interviewed him for a column I wrote then.

    I’d like to see him think seriously about why people are transgender, and not just dismiss them as deluded in some way. My son is married to a trans guy. They began exploring that idea about 10 years ago (they’ve been married 21 years) and, as he said, “it explained so much.” It’s like giving up on Ptolemaic epicycles in favor of Copernican (also Kepler and Newton) orbital mechanics. Everything is simpler that way.

    This Christmas Day, there were six people at his house for dinner. Three, or maybe four, are trans (two in each direction). Three, or maybe four, are autistic (not the same three). And some other assorted brainweirds were represented as well. Clearly, there’s a lot of self-selection in such a gathering; but it seems obvious that there is something real out there that such people are recognizing. None of these people is a publicity hound (like Caitlyn Jenner, possibly, or Chelsea Manning); none of them is a sexual predator using a trans claim to gain sexual access to members of the opposite sex (which sex is opposite, anyway?).

    Some people are born with their brains wired up in one of many possible non-standard ways; given how weird and complicated biology is, it doesn’t seem prudent to rule out “transgender” as one of the possible ways.

    Spin some ideas about this for us, Greg.

    • Peter Lund says:

      Copernicus had epicycles as well. Plus worse predictions and/or required even more epicycles. It didn’t really become simple until Kepler and natural until Newton.

      • linsee says:

        Yeah, I shoulda said that instead.

      • Jim says:

        Yes, Kepler’s use of ellipses was a huge breakthrough. Hipparchus had tried eccentric circles and I vaguely recall reading somewhere that somebody had tried Cassini Ovals before Kepler. Kepler hit upon the right idea after trying virtually all the wrong ideas. After he had published his results Galileo rejected them because he considered elliptical orbits to be too complicated.

        When Edmund Halley was visiting Newton one day he remarked to him on the question of whether an inverse square law would imply Kepler’s Laws. To Halley’s astonishment Newton replied that he had a proof of that. He told Halley that he would find the proof and show it to him. Later Newton told Halley that he had misplaced the proof. Newton had lost one of the very greatest scientific discoveries of all time!

        At Halley’s urging Newton then wrote the Principia. When he sought to have the work printed the publishers told him they would only do it for a fee (no doubt a sound business decision). Newton wasn’t willing to part with any of his money to get the Principia published but fortunately Halley arranged to pay out of his own pocket for the publication.

      Transsexuality is characterized by a conviction of having been born in the wrong body. The prevalence of transsexuality is 1:10,000 for male-to-female transsexuals and 1:30,000 for female-to-male transsexuals.

      Seems to be much less prevalent than homosexuality.

    I have commented less and less over the last couple of years (in the Steveosphere), and now have stopped because I simply do not have the time or energy to think deeply at all about anything anymore. Cochran’s style works perfectly for me: just telling me what’s what 🙂

    I read Cochran (and Agnostic) from time to time at GNXP, but it was “The New Germ Theory” that rocked my world. I love 10,000 Year, too. And don’t get me started on the series of posts on Paternal age and de novo mutations 🙂
    Simply, I read Cochran because he’s the smartest and wisest person I’ve ever come across. What makes him special is that he is strong in all his senses; not only did his intuition not get short-changed by being strong mathematically, he’s richer in that area than most.

    I only wish Cochran commented more.

I am also further proof that Greg pitched this blog too damn high, since I missed out on the National Merit Scholar love fest earlier.

    I come here because I enjoy it. Greg has a somewhat similar background to me, so I understand the way he makes his points. Greg does his homework, and is very careful in the way he constructs an argument. On the other hand, I also appreciate a man who tells it like it is. There comes a point at which I just want it all laid out there. On the gripping hand, I also appreciate that Henry is here to occasionally rein Greg in. I need that myself from time to time. I also come here because this is where i learn something new. I like to find people who know things I do not, and read what they have written.

    PhD in social sciences (US university). Eastern European, former commie country. Spent years north (Nunavut) and south (like South Carolina). UK and Russia as well (I mean living, not traveling). Other countries too. Unsatisfied with the state of the social theories at first, came to the believe that they intend to create artificial stupidity and plant it at the end (either cthulhu or the aliens must have taken over in an all-out war that no one remembers or without anyone noticing – i mean, except Greg).
    Came to the conclusion that no social theory can be satisfactory without taking into account biology. Came to an understanding that most sociologists and anthropologists of culture do not realise that in fact humans do have bodies – they did not know that. Never had heard of it. They were mysteriously lacking that awareness. Came across and learned more than in 5 years of graduate studies. Enjoyed 10 000 years of evolution more than anything I’ve ever red. Great fun, smart and entertaining, elegantly and easily broke the icebergs that had crowded the field up to the horisont at this time. A reader here once said that Greg have so much talent he could have been another Mark Twain if he wanted to (referring to his sharp style and affinity to sniff and expose the absurds). Compliments to Prof. Harpending as well. Happy New Year. Godspeed to both and keep writing.

      Yes, the fundamental fact about humans is that they are biological organisms. They are not fallen angels, transcendental entities or exemplifiers of the Hegelian dialect. They are biological organisms (like wombats but not as cute).

      As biological organisms humans are the result of an extremely complex evolutionary process that is totally meaningless.

      • st says:

        Hey Jim. What I meant was that History of Sexuality by M. Foucault is a major part of the mandatory curriculum in most PhD programs in 1.Sociology; 2.Anthropology 3. History (perhaps other programs as well). In his book F. sincerely believes that he examines sex and human sexes; so do the course instructors. F. disproves about 20 different hypotheses about the nature of sex. You would think he’d reveal at the end the true nature of the subject. But there is nothing in the end. It’s null. He suggest that sex and sexualuity do not exist. Nor human sexes. There is nothing there, it does not really happen. Never. It is all social construct – no substance. So it is sort of disappointing ending, no secret is revealed because there is no secret . Of course, one would think that Foucault was probably influenced by his own homosexuality and has been working his way back to the human norm by stretching the norm long enough to accommodate his own sexuality. I guess he made it, there is global change in most social norms nowadays. And in the norms of social sciences as well. So, forget Hegel and the fallen angels. Forget Sociology and History as well. Imagine F. makes it to the curriculums in biology? Remember Solomon Asch experiments from the 70-es?( Cochran and Harpending blog is a bit like an antidote. Or a refreshing drink.

    I’m a Russian born mischling in my late twenties, I have a STEM background. The experience of living in New York compelled me to do an internet search for “race and IQ” a few years ago, which led me into the “Sailer-sphere”. You have a unique ability to concisely cut through the obfuscation and disinformation that are prevalent in politically sensitive areas of research. I have come to greatly respect your judgement and insight.

    As far as I know, you are the only public thinker who has openly espoused the gay germ theory. The gay germ theory is the best explanation for human male exclusive homosexuality that I have encountered. This theory also has some disquieting implications, particularly in relation to the possible modes of transmission and certain behavioral pathologies. It has been my experience that otherwise conventionally minded people are generally quite open to the gay germ theory, far more so than they are to the topic of race and IQ. I would like there to be a published paper on the topic or at least a thorough blog post to which I can link interested parties. Entering “gay germ” into wikipedia currently redirects to a section of the “biology and sexual orientation” page that no longer exists This theory needs more intellectual weight behind it before biologists can feel safe to pursue the topic.
    Genetic data over the last few years has given us great insight into human ancestry, but the data has yet to be organized into a coherent picture of the human population movements before 10,000 BC. As I understand it, the modern humans that left Africa had a negroid phenotype. The caucasoid and mongoloid phenotypes seem to have emerged from a northern population within the last 40,000 years. As these northerners migrated south they pushed the older negroid phenotypes to the peripheries of Eurasia. This is according to my readings of anthropologist Peter Frost. I recall that you have written very evocatively about the migration of the Early Farmers into Europe and their interactions with the Western Hunter Gatherers, it would be great if you could use your knowledge of genetics to extend this sort of analysis further back in time, to put a face to some of the older and more obscure populations that have contributed to our ancestry. Human prehistory is a series of Conanesque sagas waiting to be told.
    I would like to know about your thoughts on the life extension movement. Do you take any supplements or nootropics?

    • Jim says:

      The migration of humans out of Africa goes back something like 100,000 years ago so I would be cautious about using terms like “negroid”, “caucasoid” etc. that to most people
      primarily refer to present day phenotypes. For example present-day Sub-Saharan African populations could be very different from the first humans to reach the Eurasian continent.

      • Rye says:

        “For example present-day Sub-Saharan African populations could be very different from the first humans to reach the Eurasian continent.”

        There currently exist ancient human populations in Southeast Asia whose phenotypes would not look out of place in the Congo, this despite being no more closely related to Africans than to other Asians. This fact, along with some scattered anthropological evidence, strongly suggests that the “negroid” phenotype was basal in Eurasia. This is one of the issues that I would like for Greg to clarify.

    I would like you to review Joe Henrich’s new book The Secret of Our Success and comment on how your views on gene-culture coevolution interact with his ideas. I thought the book was extremely well done but would like your input. More posts on culture in general would be good too.

    Like some other readers, I would like more posts on group selection as well. I read some posts in this debate on Edge, but it seemed to resolve nothing. Why are scientists so unable to get to the bottom of this issue?

To me the main interest of the blog is the new light being shed on prehistory and I have been pleased to see so many results from linguistics corroborated by hard science. I can’t remember how I got here, probably Sailer or Derbyshire. It is also a pleasure to see left wing dogma about intelligence, sexuality and race being eroded by science. On no account dumb the blog down, I like being stretched.

    This is a fairly typical example of a trigger that might bring me here. Sometimes I come just to browse. I’m no specialist but I find evolution/biology interesting and I’m fairly certain the information presented to the general public on these topics is, for the most part, heavily filtered for political/ philosophical hygiene. Whereas, I believe you will approach such topics as a truth seeker.

    I also put effort into following Razib Khan’s posts over at Unz but I find he has a narrower range of interests. Unsolicited recommendation: how about posting on the Unz site? I imagine they’d love to have you.

    I’m a university professor of anthropology. My specialty is European and Near Eastern Paleolithic. My memory of how I found this blog is patchy, but I think it involved familiarity with Henry’s publications and your book (10,000 Year Explosion). I became a regular reader because I wanted to stay up to date with genetic research, and you are one of the few people who can speak about the big, sweeping issues without sounding like an ideological buffoon. That you are able to shine a light, in such a crushing fashion, on such ideological silliness in modern science and public opinion, keeps me coming back. I can’t get enough of your posts on prehistoric genetics, and I’m always happy to see more from Henry.

      … Oh, and also, I have a nagging question: I understand that the Yamnaya is what is now recognized as official PIE people. However, I am a bit less clear on Funnelbeaker, the megalithic-burial people. It looks like, matrilineally, they are LBK-descended. However, I have not seen enough information on their genetic background.

      We know that the LBK, culturally, were in decline by 4500 in Central Europe, at least a full millennium before the Yamnaya people’s arrival. What was the cause of LBK’s decline there? Who were the TRB people replacing them: farmer-admixed descendants of Ertebølle hunter-gatherers in the North or someone else, possibly from the East? If the former, what happened to the LBK, who had been successfully overcoming other hunter-gatherers, to cede to these arrivals? Internal cultural collapse? Ecology? Funnelbeaker/TRB were a somewhat more primitive culture, it looks like…

          Thanks for the good input. Many points in the essay align with all that I’ve read so far via westhunt, gnxp, and eurogenes. Albeit the 2nd part of the article concentrates on the eastern wing of the steppe expansion (which is less interesting to me), I broadly liked/agreed with most. The only dislike I have is for the brief epilogue, regarding worldview from “Afro-Asiatic milieu” (whom exactly: Amorites? Jews? Muslim Arabs?). I am of different opinion.

          Anyway, my original question on Funnelbeaker vis-a-vis LBK circa 4500 BC still remains. Something happened in Central Europe, pre-3000 BC, pre-Yamnaya/Corded Ware.

So, I am playing catch up on all things genetic and HBD, and find the evidence interesting, fairly compelling, and enjoy the speculation on things in general.
    The last couple of days I’ve been reading some old interviews with you regarding the Middle East (mainly Iraq), and wondered if your views on the Islamic world, terrorism, etc. have changed in the past 10 years?
    It’s interesting, for example, that Jayman’s first comment to your last post about numeracy was the exact opposite of my assumptions about the implications of numeracy as it regards jihadis. I note that you make the same argument in these interviews way back when: numeracy tells us that Islamic terrorism is of little consequence. Do you think the same today?
    In any case, I really appreciate all of your work and wish you the good health to keep it up.

I was curious, so I googled human diversity and found your book, 10,000 Year Explosion and I was off to the races. I found Dr. Cochran’s recommendation for The Horse, the Wheel, and Language in this blog and read it.

    This blog is interesting to me because since coming back to reason my interests in science are varied, from early human history to quantum physics, to cosmology and this blog talks about all that and more!

    I”m 54 with an MS in Geology (Google “Goldstein Peak zircons”. I have taught HS Science and Engineering for 32 years. I found this site through the zman blog about 2 years ago, and love it. Haven’t read the 10,000 Year Explosion book yet, but it’s now on the queue. I recently came upon something that implied that the Navajo and Apache arrived in the Four Corners about the same time that the Puebloans disappeared, and not a coincidence. Anyone have anything on the Athabascans (with a truly Mongolian ancestry) ‘upending’ the Puebloans? Other than that topic, I’ve been really interested in this whole HBD subject, and look forward to more. Good stuff, Greg.

    • Jim says:

      The Southern Athabaskans are mostly relatively recent arrivals in the American Southwest probably in the last 1000 years or so. They probably came across the Great Plains since their languages are more similar to languages like Chipewayan, Sarcee, Beaver spoken in Canada than they are to West Coast Athabaskan languages. The Toboso, Jumano and related people who lived in the Conchos River Valley are thought by some to have been Athabaskan but they became extinct in the 18th century and little information is available about their language. They were sedentary and the Spainish never called them “Apacheria”. It they are actually Athabaskan they may have come from an earlier migration.

      The abandonment of Mesa Verde and other Northern Pueblos probably had more to do with pressure from Ute raiders rather than Athabaskan. The Hopi are descendents of Ute raiders. However climatic factors may perhaps have been more important.

      The Jicarilla were first repotrted by Coronado in the Llano Estacado. The Southern Athabaskans were driven to the South and West by the Comanches who were a Shoshoni band who entered the Llano Estacado about 1700.

      The relations between Southern Athabaskans and the various Pueblo people varied. There was trade as well as raiding. The Southern Athabaskans were part of the conspiracy that lead to the Pueblo Revolt of 1680.

    • gcochran9 says:

      “truthers” – full of it.

      • Michael says:

        Not being a truther, I still find confusing the manner in which building 7 fell. Do you think that skyscrapers are flawed in some way?

        • Some Troll's Legitimate Discussion Alt says:

          WTC 7 had ~40,000 gallons of diesel fuel in tanks built into its basement, connected by a system of pressurized pipes to generators on its fifth floor. It had multiple multi-floor sized gashes torn out by falling debris, at least one of which can be seen in photographs to be approximately in the area where the fuel lines were. When the rubble was excavated no fuel was found left in the tanks, in the pipes, or in the soil around them. It was all just gone.

          So it seems likely that the damage that WTC1 inflicted on WTC 7 as it collapsed was severe enough to both breech the fuel lines and render the leak detection system inoperable. With the pressure in the lines dropping and no alert from the leak detection system, the pumps in the basement kicked on and start pumping fuel. Without anyone there to turn the system off the pumps emptied the entire load of fuel onto whichever floor(s) the leak(s) were on, feeding the massive fires which then went entirely unopposed.

          Add to this the 20 odd electrical transformers quite capable of exploding under stressful conditions like being left in a huge fire for hours on end and all the other structural damage falling debris caused besides breaching the emergency power system’s fuel lines. I hope that dispels some confusion.

          • Michael says:

            It doesn’t, since tbe NIST report refutes the notion that the diesel system had anything to do with the collapse.

        • another fred says:

          “Do you think that skyscrapers are flawed in some way?”

          Some designs were more precise and interconnected so that failure of one component could compromise an entire structural system. Older buildings were more robust because they were designed on rougher approximations with larger safety factors. After the failure of the front portion of the Murrah Building exposed this flaw this became something of a topic in design and changes were made, but many buildings exist that would not be built today because of the lack of redundancy.

  125. Dale says:

    A subject that I would like to see explored is the “Flynn effect”.

    As far as I can see, the observed effect is real, and the evidence suggests that it is a robust, general effect. On the other hand, there aren’t any claimed general explanations for it.

    Herrnstein and Murray, in “The Bell Curve” generally follow their data wherever it takes them, considering that observations indicate the true state of the world. But they only briefly discuss the Flynn effect and they dismiss it as some sort of measurement error, without giving any support or explanation for that decision.

    The Flynn effect is what you would expect as a consequence of natural selection in societies where success is significantly correlated with IQ. And the observed differences in national IQ averages seem to be correlated with the length of time that their populations have had cultures that reward merchantile or bureaucratic success — China has the highest average and Congo has the lowest. And if those differences aren’t purely environmental, they must be due to natural selection.

    • Douglas Knight says:

      The Flynn effect varies in strength between tests. This paper claims that the Flynn effect is stronger in tests that exhibit a larger learning effect, how much the score goes up on taking them a second time. I don’t remember exactly what conclusion they draw from this, but it suggests to me that the Flynn effect is superficial.

    • gcochran9 says:

      “The Flynn effect is what you would expect” – not from selection, it isn’t. insufficient time, and the selective pressure likely has the wrong sign.

      • Dale says:

        Well, the sign of the selective pressure is hard to estimate. Yeah, it looks like the idiots are protected and have more children than they ought. OTOH, who are the real fathers? Women who aren’t tied to financial support from a husband must be much more willing to get pregnant by a high-status male who won’t marry them.

        I’d love to see some real data as to who is actually having the children, but I’ve never seen any. Perhaps you have? I’ve mused that if we could get DNA sequences from everybody on the planet, we could reconstruct genealogies going back many generations.

        About the only data point I know is that the term “man sharing” turns up in discussions of American blacks and marriage. That would suggest that the population of black fathers is biased toward the more successful black men. Certainly, if I wanted to devise a program to apply natural selection to a human population, affirmative action for the most successful males and jail for the least successful males would be one way to increase the variance in male success and increase the selective pressure on any heritable success factors.

        • gcochran9 says:

          I’ve heard it mentioned before, but I’ve never seen the slightest bit of evidence for the trend you’re suggesting. I doubt it like anything: not so much the possibility infidelity is higher in this population, but that it’s as high (and as directional) as would be necessary to have the kind of effect you’re suggesting.

          • Dale says:

            Somebody who isn’t blinkered by the common prejudices needs to investigate this in some detail. It seems to be universal that people think that the average IQ of a population is fixed for all time. (E.g., as the basis of the liberal terror of the idea that average IQs differ between ethnic groups.) But there seems to be no evidence for this idea, and a considerable amount of evidence that it is false: Measured IQ averages are rising. The average IQs of different nations differs substantially. The IQ of American blacks seems to be considerably above that of West Africans, more than can be accounted for by European admixture — and certainly the West Africans didn’t pick their best and brightest sell into slavery. As one shrewd writer observed, “This notion that ongoing natural selection is not the default — that it only happens on national holidays or whatever — is fairly common among biologists.” It sure looks like natural selection on IQ happened, and is still happening.

    It still amazes me that mainstream thinking insists there is no HBD, particularly inside the skull. Mainstreamers seem to believe that tens of thousands of years of human evolution, in all sorts of different environments, has led to absolutely no average population differences in behavioural or other mental traits. If any of them read this blog it would be interesting to see their positive evidence for this politically comforting but highly unlikely hypothesis.

Engineering itself is rather evolutive, you don’t make a new car/plane/gun/computer from a clean slate, you base a new design on previous successful designs, even “intelligent design” must effectively be evolutive. Understanding all this provides some clarity, it helps you see why the Congo basin will probably never become a leading source of rocket scientists, why social policy should make sure to not have dysgenic effects, or why people like me should make it a primary life goal to maximise their number of offsprings with a well-chosen mate (I think 7 children is a good and realistic goal for me, I have a very high opinion of my DNA). Reproduction is like voting for your own DNA and someone else’s DNA too, and the results of that vote can live on practically forever. If things go well in a thousand years almost entire nations will be descended from me, they won’t remember me but the effects of my choices will have endless repercussions.

    I feel like reading this blog provides the readers with rare insights, and that in comparison most people (and even many anthropologists) are like babies, stuck in a dogmatic denial of the most basic aspects of understanding what differentiates modern humans, and clinging to a view that individual interests should prime (whereas I believe that people destined for any kind of failure should keep on failing and people should follow their instincts all the way to their doom). While we find out how or why some people evolved certain adaptations the world around us insists that there is no such thing, only cosmetic differences are real. However I’d like to stress that my interest in this blog isn’t in seeing the deniers of the basic facts being proven wrong over and over again, but rather to leave the basic questions behind and learn about our best understanding of human evolution and anthropology

    All this leads me to being less political, I can’t even come close to claiming an ideology, I can’t even decide if I’m against or in favour of mass immigration, I believe it’s a catastrophe but that on the other hand if anybody is dumb enough to inflict that on themselves they shouldn’t be shielded from the consequences of their poor choices, same thing with abortion. It also leads me to see silver linings everywhere, I feel like by being less constrained than in the previous centuries (no one is making you get married young anymore, and no one is making you pretend to be heterosexual) and by having contraception so widespread we’re quietly entering a new era in which predispositions for certain behaviour are newly extremely disadvantageous. It might seem like society is going down the drain, but in my view it’s just extreme selection at work, women who prefer their career and travelling to marriage well into their 30s will take their DNA to the grave, the more promiscuous homosexuals don’t just stop breeding, they’re actively killing each other, white people who choose miscegenation are effectively exiting the gene pool of their white peers, people who can’t help but stuff their faces won’t do well either, all while the Amish are slowly selecting themselves into being more innately Amish while their numbers blow up. I think that the transition to almost purely choice-based reproduction (people only make a child if they actively want to) might just turn out to be the most significant transition in our evolution in the last few thousand years.

    That’s why I believe it’s so important to understand the world through evolution and anthropology, someone who doesn’t might step on an evolutionary landmine by associating themselves with a mate who believes that it’s better to spend one’s money and life on travel than on a family. It can also save you some time and energy, in case you were inclined towards looking for the next Einstein in Papua New Guinea.

    Not sure if that’s a suggestion but I wish we could get more insights (and maybe a bit of speculation) from genetic simulations, for instance simulating and quantifying drift should be easy, figuring out how selection pressures with heterozygote advantage should affect allele frequency should be interesting. For instance you could probably figure out how relatively advantageous heterozygous sickle cell anemia might be based on its actual frequency, then simulate its evolving frequency when there’s no more malaria around, depending on how well homozygotes are saved.
