IQs on the Decline

Posted June 30, 2018 12:00 AM by M-ReeD
Pathfinder Tags: Cognitive IQ

It should come as no surprise that since the 1970s, there has been a significant decline in general IQ test scores.

Celebrating stupidity via the shows and movies we watch and the books we don’t read, offers up more than enough evidence to back the theory being asserted by Bernt Bratsberg and Ole Rogeberg from Ragnar Frisch Center for Economic Research in Norway who conducted the research and published it in the journal PNAS.

To reach the conclusion that IQs are dropping, the team looked at the IQ test results of young men entering Norway’s national service in the years between 1970 and 2009. During that time frame, of the almost 750,000 tests analyzed, it was determined that test scores dropped, on average, seven points per generation.

But why?

According to the study, some of the reasons are likely due to environmental factors such as changes to the education system, and children reading less and playing video games more.

"The trends are not due to a changing composition of families, and that there is at most a minor role for explanations involving genes (e.g., immigration and dysgenic fertility) and environmental factors largely fixed within families (e.g., parental education, socialization effects of low-ability parents, and family size)," the researchers wrote in their study.

"Their influence is negligible compared with other environmental factors.”

What do you think is responsible for the worldwide decline of IQs?

My personal, at least partial, guess is the introduction of this dead-eyed, valley-girl speaking collection of morons.

The intelligence to accomplish any task remains constant. As machines become smarter, people become stupider to compensate. Without exercise, the brain atrophies. People can't calculate without calculators, spell without spellcheck, or even figure out a problem without "googling" for the answer.

I believe you are describing the immutable law of "Conservation of Stupidity." It states that stupidity cannot be created or destroyed, but is conserved in a closed system. As the common rock becomes a silicon wafer and eventually an IPhone, human intelligence devolves towards the water bear and eventually into a Kardasian.

It took 66 years to go from man's first flight to man first landing on the moon.

Since man's first landing on the moon computing power has increased exponentially.

I don't see any lack of intelligence with those and similar achievements.

If you scrape the bottom of the barrel you'll find all the gunge.

I think you are confusing intellect with general knowledge....Another trend that may be relevant is the population shift from rural to urban, this brings with it working in a system rather than on your own, and results in specialization...Living in a city you only have to be good at one thing to make it....Maybe the IQ measurement is becoming less important and the ability to work with computers more important....The whole focus of civilization has been to make life easier and the quality of life higher....This involves the struggle to be free and independent, which requires technological superiority, this has always been so...The personal acquisition of knowledge is driven by the need to have answers to questions that result in pursuit of this goal....If we build a machine that has all the answers, and is at our side at all times to answer these questions, surely this is a shortcut that will be taken....The need for the knowledge is still there, it's just the method of acquisition that has changed...Take somebody with an average IQ from 50 years ago, and plop him down in today's society.....how would he fare?

The average IQ is probably still 100, by definition.

There is no optimum formula for condensing the multiple dimensions of mental ability to a single number, IQ. (For example, who is more intelligent, someone who speaks several languages, or someone gifted in mathematics.) The result depends on the test.

If the scores have declined, perhaps the test needs to be updated to reflect the changing environment and the mental skills needed today.

That's why they don't use a Bell Curve to determine the Intelligence Quotient.

When IQ tests were invented, most calculations were done mentally, or manually on paper...and with imperial measurements.

Now we have the metric system and calculations are checked, or made, using machines. As most of us do not use that part of our brain, several questions in the IQ test become more difficult for most, thus skewing the figures.

I guess that most practical engineers would still do well. It is the rest of them who are holding us back / making us look good.

Yes you are right! Why!
Because today more people rely on smart phones etc to work out stuff for them, the internet to give them instant answers to research rather than actually working it out themselves.

So the brain becomes lazy, followed by the person becoming lazy and they breed!

I think I've made my point!

"So the brain becomes lazy, followed by the person becoming lazy and they breed!"

...and I believe it has been well established that more educated people (which may or may not coincide with higher intelligence) have on average fewer offspring. Assuming that intelligence is at least partially genetic, it then becomes statistically obvious that the average intelligence will indeed drop over time.

DK, it appears that brich is trying to show a correlation between lazy people having lazy offspring and non lazy people having non lazy offspring ( although he hasn't presented data to support this claim )

I didn't know that motivation or the lack thereof was genetic (!)

Right. ...and I have no idea (data) on whether there is any correlation, direct or inverse, between motivation and intelligence.

This seems to be especially true in the USA, where lies are presented as facts by many politicians.

Thanks, I think.

I didn't specifically call you out for marking my comment OT, any more than I'd call anyone out for marking 3 GA's from weeks ago OT in the last couple of days. That's life.

I doubt that your sister would be very happy to be compared to an old man, though.

Events of the last year have lead many to question the intelligence/honesty of our leaders here in this country, more than anywhere else in the free world.

That may have nothing to do with IQ. Maybe it's just like the saying goes, "If you can't dazzle 'em with brilliance, baffle them with bullsh*t."

I have to agree with M-ReeD that our decline may well be related to "this dead-eyed, valley-girl speaking collection of morons," one of whom seems to hold a considerable amount of sway with the current POTUS.

I'll mark this comment OT to save whomever the trouble.

Some facts are born facts. They are called facts.

Some facts aspire to factuality. These are called rhetoric.

Some facts are not facts, but wear the trappings of factuality. These are called pseudofacts.

Some facts are made facts by pure hard and redundant work. This is called consensus.

And then there's the rest of the facts. This is called the media.

Proof positive on CR4. Many threads start out with intelligent responses and slowly lose intelligence as the thread continues.

And lets not forget information overload. With the invention of the computer and the internet an enormous and at times bewildering (and often false or contradictory) amount of information is now available at our fingertips.

In some ways it is easier to get an answer but in other ways it is easier to get the wrong answer and believe it is the right answer.

Vast numbers of internet sites via to get and hold our attention giving us spoon-fulls of satisfaction and stimulating our addiction to them, is it any wonder there is a decline in IQ when we spend so much time on twitter and facebook feeling a sense of accomplishment while really accomplishing nothing!

Actually, this is easy to explain: There are finite amount of IQ points allowed on any one planet; and since the population is increasing, the individual average goes down.

If anything, not knowing the metrics that are used in the tests to Quantify Intelligence from 100 years ago or even 50 years ago, could be different from today just from the type of environment we now have and experienced from 50 years ago.

And knowing how to google should not count for many points on the Intelligence Quotient.
