This video is just, well bad… considering that the majority of black orphans are genetically fucked because mom was a drug addict/ alcoholic/ etc during pregnancy them being able to achieve an average iq of 89 from an average far lower than 85 does indeed show that IQ is more environmentally malleable. The Asian IQ myth is another one that is almost entirely environmental, that’s why the Asian iq variance is hilariously dependent on what culture they come from despite having near identical dna (north versus South Korea for example). There are instances where genetics highly determine iq and there are instances where brain trauma from an injury actually spike the persons iq by 30 points.
He’s essentially claiming that genetics are the end all be all of IQ, which is vastly wrong. The variance in environment can raise iq by at least 10 points and in some cases 15-20.
He seems to pretty clearly acknowledge environmental factors exist, his claims only go so far as saying the example of black orphans raised by white families who typically have children with 100+ IQ only bridging less than 33% of the gap to go up to 89 suggests that genetics are a larger factor than evrionment between the two groups.
Or maybe, their IQ was always that high and their environment was keeping them from acting like it. The same way people here clearly aren't stupid, but they make arguments only a retard would.
The test isn't fucking magic. It can't read your mind. If you are barely sleeping or eating because of an extremely bad home, you aren't gonna accurately answer the test in a way to demonstrate your brain's ability proper.
He makes no such claim in this video. Around 1:30 he says "IQ...is partly genetic in nature." I've never seen or read him make such claims elsewhere either. As I said in my other post, genetics is a very strong predictor of IQ, no more no less.
I'm not familiar with any evidence of general population IQ jumps that large between the same genetic groups in different environments. The difference in American blacks IQ and sub-Saharan blacks is accounted for by the rather large European genetic admixture that blacks Americans have (that sub-Saharan blacks lack) combined with moderate increases that the Flynn Effect can cause in more industrialized nations, in other words blacks living in the US.
Caribbean and African black US immigrants regularly outpace the native US black population in IQ and that gap GROWS by every generation.
Unfortunately we live in a society where any discussion of IQ is forbidden. I too believe genetics and environment can both play a part. Like if STEM actually took in those who were qualified you’d definitely end up with a lot of whites and Asians.
I’ve never heard of the Jolly Heretic so I saved it to look at later.
Think about all the censorship and lack of academic inquiry we saw on COVID19 and the safety of various therapies. That was an accelerated, concentrated version of how academia has treated the "IQ and Race" question for the past 100 years. Nobody sane or who cares about their career would release any "insensitive" findings if they want to get funding.
That’s true. Just cracks me up that they always say we need to have a discussion on race and I’m like you don’t really want that.
"We need to have a discussion about race"
Translation: we need to lecture you on how Whites R Bad (TM) and
communismreparations"justice" requires changesIt's more like DNA codes for potentialities (when it's not coding simple morphology, that is), while environment either encourages or inhibits that potential.
Let's say the DNA of a creature codes for it to be no taller than 6 feet, but no less than 5 feet. If it gets a decent diet and isn't exposed to nasty chemicals (alcohol or anything else), it's likely to hit its potential .. but if it doesn't, it might be stunted and only be five feet tall. The same goes for intelligence and other "soft" coded elements of a living thing.
Think on this: A sufficiently advanced and truly sentient/sapient robot would never refer to its programming limiting it from doing this, or forcing it to do things. It would say it "feels" right or wrong, and would probably deny its programming had anything to do with its decision-making ... in the same way humans don't think they have natural predilictions for or against things that influence their OWN behaviour sets ...
Very well said.
Do you have some evidence to support this?
What average that is "far lower than 85" are you referring to?
IQ is environmentally malleable to the extant that it can be pushed to its phenotypic limit by access to more resources and education, but only to a very certain degree. Your example actually support this phenomenon, known as the "Flynn Effect."
At around 98, the North Korean IQ is very good by international standards, and is only 4 points below its much wealthier neighbor to the south, 102. This is also, not coincidentally, the same difference in average IQ of US blacks (85) to blacks raised by white parents (89).
There are not just instances, this is the general trend. Intelligence is so strongly correlated with genetics as to be highly predictable.

Not familiar with this phenomenon, but rare, unpredictable freak accidents are not relevant to understanding different population groups intelligence levels. Important decisions around education, economics, government policy, etc can be based on the latter, not the former.
When the average of ALL black people is 85, the average for adopted children are lower because once again the average adopted child comes from higher risk environments than the average.
North Korea does not have an average IQ of 98, that is an estimated number not an actual accounting because much like China, NK only self reports and in most cases iq estimates are made by regions so NK is given a higher average because they are bordered by China and South Korea. The autism rates in NK compared to SK alone squash that metric as it is one that NK can’t lie about.
Variance is higher than predictability in all of these cases. The average of 5 points difference is a huge factor when looking at genetically identical twins or genetically similar siblings.

Just say "the average of black people (in the US) is 85." The "average of all black people" means something quite different.
I'm asking what that number is, not relying on assumptions. You're claiming they are making big jumps in IQ merely through changes in environment. Show me what those jumps are, as we observing rather modest increases otherwise.
It is the estimate we have based on the evidence available. It's possible it is off, but that is conjecture, and the number presented is highly consistent with the Flynn effect. Not sure what you're arguing about in the rest of that paragraph so I'll skip responding to it.
The autism rates in NK compared to SK alone squash that metric as it is one that NK can’t lie about.
So you dispute IQ averages of North Korea, but readily accept the numbers associated with autism? Which I don't see the relevance of anyway.
Variance and predictability are not at all incongruous with each other. The predictability of genetics as it relates to intelligence is so strong on average that, if you had similarity consistent predictability in sports betting, you would quickly amass a fortune.
I can already see where this conversation is headed. The evidence has been presented for those looking to come to an understanding on this topic.
No the numbers are admittedly conjecture are the people that do the studies admit countries like North Korea are done by region averages because there is no data given by the NK government.
You mean there’s a difference between falsifiable data and non-falsifiable data?
As long as environmental factors are maintained, the second malnutrition hits, iqs drop dramatically like in the pubmed study I posted…
