Loss of Applied IQ Among UK Youth? 594
Baldrson writes "The UK Times Online reports that: 'After studying 25,000 children across both state and private schools Philip Adey, a professor of education at King's College London confidently declares: "The intelligence of 11-year-olds has fallen by three years' worth in the past two decades."' 3 years loss at age 11 is an IQ of 100*8/11 or 73 -- a massive loss of 27 points. Although the test measures, not general IQ per se, but general IQ applied to scientific and technical reasoning, it nevertheless appears to blow 'a gaping hole' in what has been called The Flynn Effect: that IQs have been rising in most parts of the world -- particularly the developed countries."

Until the 1970s the UK had a two tier state education system. 5% of the kids went to grammar schools the rest went to 'secondary modern's' - sink schools in other words. To get into the grammar school and get a decent education (albeit not quite as good as the private education) you had to pass the eleven plus.
During the eleven plus era large numbers of kids were drilled in taking IQ tests. This continued for a while after the grammar schools had been phased out, partly due to inertia but also because there was tight competition for places at private schools which still have selection today.
so this is not a demonstration that kids are getting stupider, merely that the local effect of one bias in a ridiculous test is greater than the general bias.

Very few people paid attention in the classes. We got to the end-of-year exams, and three or four of us got 90%+ for this particular module. The pass rate was 40%. Everybody else got 30-40%.
So these imbeciles, who have shown themselves incapable of learning basic maths not once but twice, should have to resit the exams or fail the course, yes? No. Because it was very unlikely that they could pass, and because failing them would mean cancelling the second year of the course and screwing the rest of us, the pass rate was lowered so that everybody passed.
I finished college, and went on to university. Guess what? A huge part of the first year was dedicated to repeating stuff that I had spent the last two years sitting in classes for. Why? Because half the people on my course (Computer Science and Artificial Intelligence) had never written a program before in their life. And you know what? By the end of the year, they still hadn't. Not even Hello World. In all our programming assignments, we were given complete programs and told to change a couple of things ("make it print the numbers 1 to 20 instead of 1 to 10").

Education reflected this, and children were trained to be capable pen-pushers, perhaps also possesing relational and organisational skills. (It was not all bad.) Politicians listened to business leaders, and business leaders naturally emphasised the type of skills they themselves had.
However, the people who did this forgot that management does not create ideas or value. Problem-solving, creative and scientific skills took a back seat; some of this was an understandable reaction to the way education was organized in the 1970s. But they were also considered less important because they were not culturally appreciated and besides, they were not the kind of skills a professional human resources department was looking for.
The result has been a loss of cognitive ability, in part a lack of creativity, but to substantial degree a loss of interpretative ability.

Darwin described it many years ago, and called it Natural Selection. Developed society has removed the implications of being weak, and therefore made them as equal as the strong in their chances for success.
Its tough to say, but these days, to many children are stressed beyond belief at school, but in the wrong way. At school more work = smarter children, but this never happens if all that work is done incorrectly and then not corrected. To much these days children arn't told: You failed or Thats incorrect, do it again. In the current education system in Australia there is no fail. the marks on every single course range from 50 to 100.
People learn via a combination of things. 1. The rewards of succeeding, 2. Fear of failure and 3. Having initative enough to learn from mistakes.
The ultra clean environment we have made for our children is apparently weakening their immune systems. The ultra safe environment, is removeing their addaptive ability. The ultra success society, is removeing the distinction between success and failure. And the ultra information society, is removing the need for general knowlege. Sure, there are alot of good kids out there, alot of smart kids, who take the initative. But society is focused on protecting, not helping those who fail.
We have smart people, working, to pay taxes, to ensure that the people who dont work, have enough money to pay their bills for pay tv and alcohol while their kids run wild. All the same time as the smart people are having fewer and fewer children.
Another problem is that these days, the devices and tools the occupy out childrens lives cant be as easily taken apart. When i was young, i remember building a radio, playing with instructionless technic, playing with electronics, looking at motors. But now, the iPod cant be oppened, the motors in lawn mowers can only be touched by a licenced dealer, and Lego comes with specially designed pieces and themed instructions.
I hate to say it. But society needs to bring back the difference between success and failure, and therefore provide the impulse for people to learn from their mistakes, not their text books.
We need to bring back natural selection.
The best tool we have left in our stock now, is the combination of the economy and law enforcement. If the failures turn to crime, they might die or be arrested. If the failures want a job to support themselves they have to conform to that jobs regulations: pants, a tie and knowlege on a specific area. Sadly, the huge amount of welfare and the effect of liability in decreasing the law enforcement powers of the police have made these weapons weak.

Piaget was a developmental psychologist was was interested in discerning developmental stages in childhood that could be predicted and potentially nurtured with special education. He broke development down into four stages:
1) Sensimotor Stage: birth -> 2yo (a child who developed object persistence, or the recognition that a physical object persists even when out of the visual field and across time, would pass to the next stage)
2) Pre-Operational Stage: 2yo -> 7-8 (a child who developed conservation skills, recognizing that certain abstract things which appear different are actually the same, would pass to the next stage
3) Concrete Operational Stage: ~8-11yo (a child who developed abstract reasoning, such as manipulation of abstract variables in math or algorithmic reasoning, would pass to the final stage
4) Formal Operational Stage: cognitive adulthood.
This study -- cited in the article -- tests when children move from Pre-Operational to Concrete-Operational stage. They do so with a conservation skills test. In one test the researcher takes a tall and thin beaker and fills it up to a certain amount in front of the child. Then the researcher hands the child a light block and a heavy block and asks the child where they think each will displace the water in the beaker. If the child realizes that both displace the water equally, the child understands conservation of water displacement.
They then move to another test where the child is faced with a tall set of blocks stacked upon one another, and a short and wide set of the same blocks stacked upon one another. The researcher asks the child to use the short and wide blocks to build the same tower as the tall and thin one. If the child realizes that since both contain the same number of blocks it is actually possible for him/her to complete the task, the child understands volume conservation.
In yet another test, the researcher takes one cup of water and pours it into several smaller cups and then asks the child where the water line will be if they pour all the water from the smaller cups back into the larger cup. Ya'll get the idea.
Now, these researchers are testing children today using the same methods as Piaget back in the 70s. What they found is that the mean for transitioning out of Pre-Operational Stage is today later than it was back in the 1970s. They don't know why. Is it due to changes in our educational system? If it due to environmental changes? Hell, how about: does Paiget's development model hold any factual water? *cough!* Are these results meaningful, and what do they mean?
I don't know.
But one thing I do know is that these results say NOTHING about relative IQ differences from then and today because neither study measured IQ!!!! It is a gross misunderstanding of this work to compare the actual results of relative changes in children developing specific conservation skills over time, and then claiming that these results can extrapolate general intelligence changes in children over time. They are not the same!
To sum up, baldrson misses this "IMPORTANT LAB RULE": know what you are measuring and confounds it with a second "IMPORTANT LAB RULE": take accurate measurements. So, now that we have that all cleared up, how 'bout heading over to the pub for a Guinness?
How can IQ drop... or grow? (Score:3, Interesting)

Basically, the closer they could come to matching your specific circumstances to those similar to you, the more accurate your IQ measurement was. There was much discussion about how both questions and distribution had to be changed to remove cultural bias inherent in the testing. So if you were straight down the line as being average, you'd have a score (IQ) of 100. If you were below average, you might be 70. If you are above average you might be 130.
So can someone explain to me how the IQ can be dropping when it is meant to be the measure of the average? The percentage of people in the demographic obtaining a score of 100 should remain constant. I understand that the number of correct answers might diminish or increase over time, but the percentile of people scoring 100 and the distribution of the rest should remain the same otherwise the scoring is flawed.

I cannot imagine how other provinces ("Counties" here in the UK) manage. Grammar schooling was abolished in every other county, and there is a serious movement to abolish them here. Why? Through some twisted use political correctness and an attitude of, "All are equal in ability, thus, it is unfair to split staffing between schools, where the grammar school may take the better staff due to a more prestigious position." Luckily the Labour party has recently begun motions to keep and enhance selective schooling in the country, which I think is a good thing.
However, back to my experience. Technical and applied sciences are sorely, sorely lacking. I had a girl in my economics class a few weeks ago requiring explanation and a little time for the mathematical cogs to grind to work out the total sum of 50 - 40 = 10.
I am not joking.
I believe I know the problem, and it purely is our society, and the crap we are force-fed, and most of use ingest. Who to blame for this, I'm not sure. Maybe corporations aiming to control our habits from birth, maybe lazy parenting, maybe government attitude, likely a combination of these things and more. I am however certain of the society in my school.

+ Major point: None of us watch TV. We do grow a liking to a certain series here or there and we watch (Much which is popular here, too. Futurama, Firefly, BS:G and so forth), but none of use sit in front of that square box and just sit there mindlessly because we don't have anything else to do.
+ We learn where we can in school. Let me explain this. I have slowly and methodically found out school grades are in no way whatsoever a representation of intelligence in any way. They are simply a test of memory, this is how ninety-five percent of the school treat it, and that is how it is taught. You never have to think at any point, you are told some bare facts, and you need to memorise them. This is why some truly idiotic people can get good marks. I think a further factor why science and maths is worst hit is that is requires minimal amounts of though, we have to memorise equations, sure, but then we have to APPLY them. Oh that scares them. They didn't memorise that one. We as a group want to truly learn. I aced triple physics with an A* at GCSE with barely any revision, it being the toughest physics test open to me at the time, simply because I've always been interested in physics, and how the world works.
+ Peer pressure of hatred of science and learning. Being a geek, I do of course have geek attire, such as the exceptionally cool, "Shroedinger's Cat is dead" T-shirt from ThinkGeek.com. Ninety-eight percent just don't care, ask, and as I'm always willing to teach, start off with the phrase, "It's about physics..." knowing it'll scare them off. They don't care. They don't want to stay and listen. Their social position may fall! However, people have complimented me on this T-shirt, in private. Girls especially, I'm assuming because they have a greater "pack" society. We don't do t

Recall that places like India and China have, for various reasons, not been the best places to foster intellect in recent times (the last two or three hundred years). The people there are just as intellectually capable as anyone from a Western nation, but did not have many of the advantages that Western society was able to offer due to its better economic position, and so forth.
But times have changed, and education is far more available in places like India and China, in addition to many other developing countries. So it's no wonder that the comparative IQ gap between Western and Eastern cultures is closing, and closing quickly. It's not because people in the Western world are becoming stupider; it's because the people in the East are now able to take advantage of better educational opportunities.

Three years difference in scores is likely going to be substantially less than 27 IQ points. Figuring it out precisely is difficult because there is a huge spurt and then dropoff in the rate of increase in intelligence on a ratio (Rasch-based SB5 CSS score) scale from about 8 to 12, peaking at age 10. Testing would be a more accurate way of finding out the IQ equivalent of 3 years difference at that age in that population than attempting to calculate it anyway.
