IQ rates are dropping in many developed countries and that doesn't bode well for humanity

Twin adoption studies would suggest otherwise as it relates to base function and heratable traits. No doubt environment can squander the inherent advantage but the advantage still remains.

 

more like high carb western diets

 

You may want to strategically avoid threads that revolve around IQ levels.
Just sayin’

 

Why didn't you and your sister mentor your younger brothers?

 

What "variation in multi-racial societies where different races have existed for generations"? Source and name of countries please.

Only evidence of such a thing I've seen in America, a place with a history of segregation and thoroughly failed integration. Completely different cultures, completely different environments, exactly like comparing two different countries.

Do you have anything for other countries? Otherwise it's a very chauvinistic worldview, projecting your country's specific problems on other races as a whole.

They are, and demonstrably so. The average IQ of black Americans is 85, the average IQ of Subsaharan Africans is around 60.

Can be anything from one generation to it never happening. It's not a question of time, it's a question of integration and assimilation. Which relies on personal responsibility.

Aren't conservatives supposed to believe in personal responsibilty? Sounds to me like your genetic determinist worldview is all about saying people have no responsibility for their actions.

 

Are you talking about the Minnesota Transracial Adoption Study? Then it doesn't. The study only shows heritability for children that were placed at a late age in their host families, children that were placed at an early age have almost exactly the same IQ as their hosts.

Is this about some other study? Source please.

 

IQ is a western idea. I highly doubt that any significant number of people living in the Amazon rain forests or Kenyan jungles or the Siberian ice shields has even heard of IQ tests, let alone completed one. IQ Tests as a measure of intelligence is so primitive and redundant. As for IQ in the US dropping due to immigrants has it not crossed your mind that the majority of those immigrants do not have English as their first language. Perhaps you could do an IQ test in Swahili and see what score you get.

 

If IQ tests have a "Western bias" then why do China and Japan score higher than Western countries?

IQ tests do not depend on language. They're only based on images.

That's just your typical IQ test on the Internet. I had my IQ tested by a professional and I saw no such thing. It was only logic on images, photos, building blocks, that kind of stuff. There are different types of tests but language is not a requirement.

Besides the IQ tests in their home country are done in their native language. So the IQ difference is not due to a language barrier.

 

I missed answering this: Because the Chinese and Japanese education system is test orientated. The more you practice tests the higher score you will get.

 

How many people living in the "Amazon rain forests or Kenyan jungles or the Siberian ice shields" have their IQ tested by professionals?

 

Agree, education plays a huge role. But there's no "Western bias", any country can have proper education.

Pretty sure that's been done. There's quite a lot of scientific papers on that kind of stuff. On Australian aborigines for example.

 

But this OP is not in reference to education; it's referring to "intelligence".

As for the aborigines, I quote someone else's words below which I agree with:

 

Ideocracy was, sadly, a documentary.

 

Education, especially early childhood education by parents, is crucial in developing intelligence.

Up to here, it makes sense. They fail IQ tests because of a lack of education, that's reasonable.

I also completely agree with the methodology of having them practicing other tests for a few days before giving them the actual IQ test.

This, however, is laughable. Did he just say that the ability to survive in a hostile environment is intelligence? With that logic insects are the most intelligent species on Earth.

 

Your answer here suggests that you've never been administered a standard IQ test so we're arguing apples and oranges. We need to define terms for this discussion to have purpose.

 

60 is the low end, and not confined to all of sub-saharan Africa. Most of sub-saharan Africa ranges between high 60's - low 90's. Blacks in America have European admixture of between 20-30%. East Asians come to America with higher IQ than the average American of European descent, and it remains that way. Europeans and Americans of European descent maintain the same approximate IQ. Non-white children raised by white parents maintain an approximate average IQ comparable to that of other kids of the same race.

It is what it is.

 

Himmler thought so

 

I'm not seeing anything above 75.

And blacks in Africa don't?

A slight difference in admixture is no explanation for a shift from an average around 65 to an everage of 85.

Not to mention the country average takes the white minority into account too, making the black average lower than that.

What the hell does this have to do with genetics? Asians come with their culture and work ethic, and often have their own communities. A lot of them are also recent immigrants.

Okay, but they have the same culture, since one founded the other.

No, they don't. There isn't a single study that shows this.

See my previous post on the Minnesota transracial adoption study, which by the way concludes the exact opposite. If you have another study, feel free to post it.

Pseudoscience, yes.

 

Not true, intelligence in Western countries is now dropping (read the article in the OP). The weird part is that the phenomenon is happening WITHIN families..... ie. children are less intelligent than their parents (mine for instance, I was more intelligent than my parents but that pattern was reversed for my children). This phenomenon is only being observed in 1st world nations. There is heavy speculation that social media, video gaming etc... is making people dumber (or perhaps the highly processed food we eat). Brain function is heavily influenced by the way it is used.... it is possible to use the brain in a way that makes you less intelligent. If it is an environmental thing, there is reason for hope.... we have the biological capability for greater intelligence but we are failing to meet our potential.

Not so much for sub-saharans. There does appear to have been a 'back flow' at some point, but not spread across the entire continent.

20-30% isn't slight, and as you'll see by the more detailed map of IQ by nation an average of 65 isn't quite accurate to describe the bulk of the continent.

Your original contention was that it's not fair to compare similar people in different environments, as it's the environment that matters. Well, here we have people coming from a different environment into an environment that's similar for people of different races, yet the IQ remains basically unchanged. You may argue it's about culture, work ethic, etc., but this doesn't address the likelihood that culture is a direct result of innate intelligence.

I'd like to see you convince Europeans that American and European culture is the same.

Pardon me, the IQ raises slightly, yet the hierarchical structure remains. Asians>Europeans>Hispanic>African.

The link you originally posted regarding the heritability of IQ suggests that ultimately IQ is primarily due to heredity (genetic), with a couple studies cited which suggests upwards of 80%.

 

We’ve had 50 years of teaching self-esteem to our kids and not the basics (math, English).

I don’t know how directly that is tied to IQ, but it can’t help.

 

While I am in no way a proponent of illegal immigration, I doubt seriously if the falling IQ's have anything to do with it. I would attribute it more to the fact that in today's world people are increasingly dependent on others to do things for them, and therefore do much less problem solving.

When I was growing up most fathers knew basic carpentry, plumbing, and basic electrical, and usually did all their own home repairs, along with their auto repairs. Back in the day, grocery stores used to have tube testers and people would even repair their own TV's. By the time boys graduated high school they had taken wood, metal, and auto-shop classes. Many more people grew and preserved their own foods, and raised and butchered animals.

Today no one knows how to do much of anything, and the less problem solving you do, the less you know how to do. It is pretty hard to formulate intelligence with a video controller or cell phone in your hand 6 hrs a day It is a downward cycle.

Quote : "The four data sets can be averaged to give an IQ of 68 as the best reading of the IQ in sub-Saharan Africa."

You yourself admit that this is evidence of nothing, since it doesn't rule out culture. And Asians and whites don't exactly live in the same environment, ever been to an Asian district?

Besides the difference of IQ between Asians and whites would be like what, 103 to 100? Hard to show anything given the margins of error of such tests.

Again, there isn't a single study that concludes that adopted black children have a lower average IQ than their foster white parents in any way. Or anything of that nature with other races.
This is just a baseless claim, prove it or go home.

I've already addressed this. You don't understand what heritability is. High heritbility doesn't mean "it's genetic", it means that individual variations within the same environment are mainly genetic. That value is completely irrelevant to comparing different groups or different environments.
