They didn’t use IQ tests. From the study that the article you posted references:

quote:

The data cover the full birth cohorts from 1962 through 1991 and include a cognitive ability stanine score from military conscription testing at age 18–19 y for the vast majority of Norwegian-born males.


And they used only tests of speed, which factor very little into more standardized, full scale IQ scores from the Wechsler scales
quote:

Following convention, we calculate the IQ score from the aggregate stanine score given each conscript based on three speeded tests of arithmetic (30 items), word similarities (54 items), and figures (36 items).

BTW, the Flynn effect has slowed down, but it continues, especially in more developed countries

"I.Q. (intelligence quotient)" is merely a subjective societal assessment of how much you fit into the "intellect" favored in that particular society.

Have you heard of the Flynn Effect? It's a thing where the I.Q. of the entire planet rises 10 points every decade. If we subtract 10 points going backwards, the founding Americans were too dumb to swallow and breathe on their own, right? That's just a measure of how modernized the planet increasingly becomes across the board... even underprivileged countries with people don't have running water or indoor plumbing now have cheap smart phones and internet connectivity... so they have access to as much information (and porn) as the rest of the planet.

Nobody is worthlessly stupid. Everybody has an area that they're a genius in. One zip code values a PhD in Ancient Languages more than a diesel mechanic, another is the opposite. Someone who lives in a remote isolated village in the Amazon basin will have a very low "IQ," but put a Western genius in their place and they'll be dead in a week of starvation or something.


No. IQ is actually actually not remotely subjective. You take the same test everyone else in your area/language/society/country/etc and where you place on that test in relation to everyone else that took it determines your IQ. Dumbed down version but that's what it actually is. A ranking. Kinda. On a bell curve so most scores are in the middle.

A 75 IQ is profoundly different from someone with a 115. Deeply. And it's simply a fact. We haven't come to grips with what that signifies and how to deal with it properly though.

This cannot be stated enough. Shoot it is profoundly different from someone with an IQ of 100. Someone with an IQ of 75 is highly unlikely to graduate high school with a “diploma“

I haven't seen any studies on this.
Only ones on the opposite.

Of course IQ test proponents are full of pseudo science.

Check out more recent Meta-analyses, which support the effect continues, even if at a slower rate. But I do concede that there is conflicting data. Thanks for those links.

I don’t know who or what you are referring to using pseudoscience? One could easily state that of course, IQ test opponents are full of pseudoscience. I’ve certainly seen a lot of that in this thread. Not referring to you.

With that being said, I do agree that the Flynn effect is not going to go on forever

Fortunately, minority vote suppression ended when minorites started voting for the party that was suppressing them.

I am just always baffled by people who insert their own "It must be true" into this.

Here is some more data.
https://www.iqmindware.com/trident-brain-training/intelligence-research/the-bell-curve-cognitive-elites/
https://opened.cuny.edu/courseware/lesson/48/student/?section=3

quote:

Any IQ score that falls within one standard deviation above and below the mean (between 85 and 115) is considered average, and 82% of the population has IQ scores in this range.


quote:

Only 2.2% of the population has an IQ score below 70 (American Psychological Association [APA], 2013). A score of 70 or below indicates significant cognitive delays, major deficits in adaptive functioning, and difficulty meeting “community standards of personal independence and social responsibility” when compared to same-aged peers (APA, 2013, p. 37). An individual in this IQ range would be considered to have an intellectual disability and exhibit deficits in intellectual functioning and adaptive behavior (American Association on Intellectual and Developmental Disabilities, 2013). Formerly known as mental retardation, the accepted term now is intellectual disability, and it has four subtypes: mild, moderate, severe, and profound


https://pmc.ncbi.nlm.nih.gov/articles/PMC6088505/

quote:

Across 142 effect sizes from 42 data sets involving over 600,000 participants, we found consistent evidence for beneficial effects of education on cognitive abilities of approximately 1 to 5 IQ points for an additional year of education. Moderator analyses indicated that the effects persisted across the life span and were present on all broad categories of cognitive ability studied. Education appears to be the most consistent, robust, and durable method yet to be identified for raising intelligence.

Its why, despite having higher IQ, Asians actually invent much less technology, they just improve upon what others invented.

I’m gonna push back on this, there’s tons of valuable inventions from Asians. There’s also a huge societal component - America specifically rewards people who take risk and succeed, like inventors. Asian countries are far less likely to reward people taking risk on a cultural level. The ingrained cultural difference there results in a slow steady push forward by a greater whole rather than having some people win big and others fail

IQ Hackers, Vitamin peddlers, Vos Savant, in general its a pseudo science ridden area.

All the data is worth a critical eye.

Oh I agree with that.

I'm less of an IQ test opponent than a it doesn't predict what people think it does person.

To not be a critic without contributing anything.

I think IQ is a fanatically good predictor of success.
But it has very large gains and losses due to diet and education along with many other things.

20-60% even in studies that want genetic intelligence to be true.

That can take a 100 IQ person down to 80 or up to 120.

So 80% of the population is within norm.

I am not sure what you’re arguing in your response to me quoted above. perhaps I am misinterpreting .

An IQ of 75 falls at the 5th percentile. Your statement that 87% of people graduate high school would indicate that even those with an IQ a few points above above 75 would be very unlikely to graduate high school. That is also very accurate. I think we might be on the same page.


I’m not sure if you to me when you say you are baffled by people who “ it must be true”. Maybe it was confirmation that we are on the same page.

The other stuff you quoted in your post was not from me. Seems like you were just posting accurate stuff.

I also find it amusing that people with lower IQ's out breed people with higher IQ's.
Low IQ people breed with impunity. They do not posses the mental acuity to realize the consequences of their actions. Poor people with low IQ cannot afford the kid they have, so they go on to have more, which leads to low IQ offspring.

quote:

In school year 2021–22, the U.S. average adjusted cohort graduation rate (ACGR) for public high school students was 87 percent, 7 percentage points higher than a decade earlier. Asian/Pacific Islander students had the highest ACGR (94 percent), followed by White (90 percent), Hispanic (83 percent), Black (81 percent), and American Indian/Alaska Native (74 percent) students.


https://reasonwithoutrestraint.com/the-scope-of-racial-disparities-in-test-scores-in-the-united-states/


15 points centered on 90 would put the lower end on on 75.

Considering how many kids drop out due to non IQ related issues, a number of those at 75 are definitely graduating, especially with No Child Left Behind.

A Person with Downs Syndrome will have an IQ between 50 and 70, many of them graduate HS, and sometimes college.

I think you are overemphasizing the task of effort and support that goes into graduating HS.

It's a mild disability, and many kids can successfully complete HS with it.

Yup
Trying to bring data into the conversation.

It's a fascinating area, but many people use it as an opportunity to throw other people away.
