I ain’t no fancy schmancy geneticist, but that appears to be what this article is saying.
The researchers did not find any individual protein-altering SNPs that met strict criteria for differences between the high-intelligence group and the control group. However, for SNPs that showed some difference between the groups, the rare allele was less frequently observed in the high intelligence group. This observation is consistent with research indicating that rare functional alleles are more often detrimental than beneficial to intelligence.
Professor Robert Plomin from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London, said: ‘Rare functional alleles do not account for much on their own but in combination, their impact is significant.
‘Our research shows that there are not genes for genius. However, to have super-high intelligence you need to have many of the positive alleles and importantly few of the negative rare effects, such as the rare functional alleles identified in our study.’

Study offers first genetic analysis of people with extremely high intelligence
So basically, we (whites) would all have the 170 IQs of the early Cro Magnon man who kicked off the agricultural revolution, except that the structure of the society that resulted from Cro Magnon instincts guaranteed a great deal of mutation accumulation, and we’ve lost about 500 cc’s of average brain volume since then.
It’s only the rare birds who win the lottery by failing to have/express these mutations (perhaps partially by anti-dysgenic breeding) who have 170 IQs now. That’s why, as expected, the white intelligence distribution adheres to a bell curve with leftward skew (and a fat right tail). The right tail is a combination of random lottery winners and the group holdouts who haven’t succumbed to dysgenia quite so profoundly as their distant cousins.
Think of it like money. If your parents are rich, you’re probably going to be in the same ballpark, maybe a little higher or lower, but some people win the genetic lottery (like Oprah, an uber-melon/SC freak of nature). On the whole though, we’re getting slightly poorer each year, per capita.

Hey Aeoli, this is a very interesting post and I agree with the basic premise. But I think your estimate of Cro-Magnon man’s IQ (real Cro-Magnon, not like “Croms” today) seems too high (I can elaborate on why I think this is), even if you grant that they had a lower rate of detrimental mutations in their genome.
Maybe attempt a historiometric analysis of their IQ based on brain size, the temperature of their environment and other factors. Or if you’re not up to it, maybe ask Pumpkin Person if he’d be up to the task.
Unique indivijools get what they ask for.
I wonder how many in the edenosphere are suffering from Depersonalization/Derealization?
I suspect I’ve had it for the better part of 10 years, and that I am snapping out of it again.
It certainly leads one’s minds to… interesting places. It, of course, also leads one to have wacky reactions to reality.
I also suspect DP/DR has something to do with the amygdala and with orexin or possibly ghrelin.
It would explain the “haunted ghost” thing that Koanic talks about. That’s how it feels, pretty much.
Crazy conjecture I came up with today:
1. It’s very common for people to get diarrhea and such when travelling to foreign countries
2. The natives don’t get it to the same extent
3. This means they probably have different gut biomes
4. We know that your gut biome influences a lot of aspects of your personality
5. Could multi-ethnic strife be explained by different gut biomes leading to incompatible personalities?
6. Could this also explain why certain cultures ARE compatible (ie Asians in the West)?
My spontaneous answer is “no, it’s not differing gut biomes, some countries just have crappy sanitary standards. Problems are explained by hormones, culture and IQ”.
Still, an interesting thought, I think.
Follow-up questions:
-Do people who migrate to the West get stomach problems?
-Are acclimatized expats in eg Thailand impacted by it, personality-wise? Do they become a bit Thai from their stomach bugs?
Wait, I think we have a bit of misunderstanding here.
There never was and never will be a Cro-Magnon with an IQ of 170.
I think what you meant was, the Neanderthal slave caste who are really responsible for the “Neolithic Revolution” (Post-genocidal spoils from the Neanderthal Alamo) were the ones with the 170 IQs.
Cro-Magnons were black-skinned spearchuckers who were essentially mobile life support systems for a pair of testicles and a schlong. They only became white from the widescale gangrape of Neanderthal female prisoners (Queens of the “Tuatha De Dananne”) and the 500cc temporary brain size increase in the offspring from attempting to steal from a superior gene pool.
There’s no credible evidence of any Cro-Magnon encampment in Europe before 40,000 years and the camps they do find are nothing more than hollows in the ground where they threw up mud huts so they’d have a place to lie and massage muh dik at night.
I’m sorry I cannot award points for effort in this event. You are certainly trying hard if that is any consolation.
Yeah, that is what I meant. I shall strive to be more precise in the future, lest I miss out on more points!
What kind of brainpower did the agricultural revolution require to get started in the first place? How could it be considered an objective good to its recipients given the massive loss of fitness, health and freedom suffered by early farmers? This particular ‘innovation’ didn’t make lives easier, but rather crueler and shorter, and lived in penury and slavish squalor (contrast them with the earlier pastoralists, who achieved stability in their food supply, and were extremely healthy) . The ‘beneficiaries’ of the Agricultural Revolution lived and died like slaves, because that is what they were; grass-eating acolytes, probably addicted to some ergot-like hallucinogen. If so, then the minds behind early agriculture were not Neanderthals, but Melons presiding over an eccentric cult. Quite likely, they were little more than a peculiar sideshow; probably at first they regularly ruined their topsoil and being inferior physically to their neighbours could not expand, so were self-limiting. It would have taken a catastrophe majorly shifting game migration patterns to leave the surrounding country sufficiently empty for them to finally expand, and begin to outcompete others through sheer weight of numbers.
And so the cud-chewing ergot-zombies inherited the earth…
