Human intelligence is increasing by approximately 3 IQ points per decade, a phenomenon known as the Flynn effect.
The increases come from one area of intelligence in particular: abstract thinking, which can be tested using puzzles like Raven's Progressive Matrices. Watch this video to see two kinds of puzzles: One your modern mind is perfectly geared for, and another that might just fool you.
In this video, David Epstein recounts a natural experiment in the Soviet Union in the 1930s that tested the intelligence of isolated subsistence farmers compared to people who had been exposed to industrialization. The experiment revealed fascinating information about abstract thinking, intelligence transfer, and how modern life has changed the way we perceive the world.

DAVID EPSTEIN:
David Epstein is the author of the New York Times bestsellers Range: Why Generalist Triumph in a Specialized World and The Sports Gene. He has master's degrees in environmental science and journalism and has worked as an investigative reporter for ProPublica and a senior writer for Sports Illustrated. He lives in Washington, DC.

TRANSCRIPT:
DAVID EPSTEIN: The Flynn effect is this startling finding that IQ scores, scores on IQ tests around the world, in the 20th century have been rising at a pretty steady rate of about three points per decade. And not only have they been rising at three points per decade, but the scores are rising on the most abstract tests and the most abstract parts of tests.
So, for example, the test that has the fastest rising score Is called Raven's Progressive Matrices. This has nothing to do with anything you've learned in school. It's just patterns, abstract patterns, in a sequence and one is missing, and you have to figure out how to fill in the missing patterns -- pure abstraction. This test was created so that you wouldn't have to bring anything to it that you've learned in life. If Martians landed on Earth, this was supposed to be the test that could determine how clever they were. And yet, it's the place where we've seen the fastest rise in scores, in this abstract thinking skills that aren't really specifically taught anywhere.
When James Flynn, the professor who first noticed this trend, for whom the Flynn effect is named, started wondering what was going on, he went back to some famous studies by a Soviet psychologist named Alexander Luria. And Luria found an incredible natural experiment. In the 1930s when the Soviet Union was nationalizing, essentially, some of the remote territories -- villages that had not been developed for agriculture and they wanted to develop industry in those places -- Luria wondered if taking people who were living in what he called a pre-modern environment where they were subsistence farmers and quickly moving them into modern work, where they had to work together and coordinate schedules and coordinate tasks for agriculture, even have some schooling in some cases, how would that change the way that they think? And so he saw this natural experiment where he came in the middle of this revolution, where dome of these pre-modern villagers -- again using his terminology -- were still in their original environment as subsistence farmers and others were getting connected to the modern world, getting a little bit of schooling; some were being trained to be teachers, others were being appointed to head collective farms and had to start managing people and thinking ahead and setting long-term complicated goals. And what he found was that this actually had a profound effect on the very way that they think. When the pre-modern villagers were given skeins of wool or silk of different colors and hues and asked to organize them into groups, they basically said, 'It can't be done. None of them are similar.' Whereas when some of the villagers who had been touched by modernity were given the same task, they pretty easily grouped them into colors, even if they didn't really have names for those colors, they started to recognize the abstraction of a color for use in grouping.
And the same thing was true with shapes. So for example, a 26-year-old remote villager named Alieva was asked to group certain shapes together. But to her, a square with a solid line was obviously a map and the same square with a dotted line was obviously a watch. She could only see them as these concrete objects, whereas the...

Maybe IQ Tests havent kept up with Humanity...
😆😆😆
Perhaps the second test is life.
Or perhaps it's cuz I keep breeding
This is actually an interesting take. They gotta re-adjust the test for the now higher average
Other way around, the robustness of the g factor is staggering. People have been trying to kill IQ for over a century but its just so fundamental in psychology that it just wont die.
IQ tests are actually updated regularly, so the score of the average person at that moment in time is 100. The average score of every generation is always the same, but the tests are getting harder. To see the difference in IQ you have to give people today older tests from let's say the 1930s and they'll score way higher on average than the ones who lived then.

The last couple sentences were the most enlightening.
The testing company i work for has been seeing a steady drop in IQ across the European union, australia and the southern west coast of the US.
Across what time scale?
My experience in life is the opposite of this video. I went to restaurant last week - the register stopped working and the college girl working there could not calculate my change. She could not subtract and was in college. I had to tell her. I donot think this is unusual today.
Why is there such stock put in to IQ scoring. The fact that these scores are rising suggests that maybe it's not a good metric for measuring intelligence.
@@Ren33469 Wow. It's easy to measure height empirically. It has been for centuries. Measuring intelligence is far trickier. IQ may go some of the way. Having worked with people with emotional/mental trauma, it has been very difficult to measure their intelligence. Their IQ scores often varied greatly depending on where they were mentally. I'm not sure if you read my comment or really have comprehension issues but I won't go and call you stupid. I'l give you the benefit of the doubt
Empirically height is a 3 dimensional object in space that can often times be measured correctly by a cursory glance. Comparing intelligence and all it entails is a monumental false equivalency. Im pretty sure you know that.
Nutrition cannot be the only reason as there are countries that have had plentiful access to food for centuries and don't come out clear winners in the IQ scores. Charles Murray researched this extensively and there doesn't seem to be any conclusive evidence as to why IQ scores are increasing.
IQ tests do work. I never said they didn't. They measure something and are a very useful tool. Where we seem to differ is on the extent and the scope of what they actually measure and how the scores can vary greatly depending on where the individual is emotionally/mentally.
@@Ren33469 Ok once again. You can resort to name calling and poor grammar if you wish. That’s your prerogative. Again, you seem to be missing my point or have poor pattern recognition.
The weight analogy, like height, is poor and intellectually lazy at best. Intelligence is a multi-faceted real-life interface constantly interacting and manipulating the environment in countless undetectable ways. Weight and height are well…. Just weight and height. They are easy to measure at any time of the day and absolutely conclusive in their results. Intelligence on the other hand is not.
Let me give you some good examples. John Lennon is by anybody’s metric a genius, just like Paul McCartney. Now these guys were self-confessed poor students and “not very smart”. This seems to be the case with many great artists. So, what you are saying is that their intelligence can only be deduced from the results of an IQ test that is very myopic in what it is “supposedly” measuring. Ok, lets look at Floyd Mayweather. This is a person who is very athletic but what sets him apart is his ability to process his environment in a split second in time and space and then calculate what he needs to do and execute it. Are you saying this is not a supreme form of intelligence? Its outright genius is what is. How does the IQ test account for this? Il wait….. Look at Lionel Messi and watch his intelligence shine like a beacon on the football pitch. It is artistry and intelligence at its finest.
You are the one that insinuated the role of nutrition. Who is straw manning here? Nutrition probably plays a role but you pointed out nutrition and nothing else which leads one to believe it plays the significant role. I started looking into this subject while doing my PhD in psychotherapy and was surprised at how well peoples IQ scores increased after, either taking medication and/or talk therapy. It appeared people’s inability to settle within themselves, have self-confidence, to focus and relax made a significant difference in how they scored on these tests. I was of the opinion that IQ scores were primarily genetics based. I was wrong. This led me down this rabbit hole. Although, maybe i'm just super bitter because i'm not intelligent at all........Ya know what i'm sayin?
Rising? Been out in public lately? People are getting dumber!!!
Well I’m not a “pre-modern villager” and I was still able to clearly see that both of the middle orange circles were the same size? So what does that mean..?
That you can have a career in identifying sizes of circles. ...or something like that.
@@gnosis8142 HAHAHA
You listened to the task and focused on the circles in question, disregarding their surroundings.
One year on and I have discovered that I have ADHD and this is apparently an ADHD trait. Our brains are wired differently and it is said they’re more like hunter-gatherer brains so I guess that’s similar to a pre-modern villager?
4:33 Beautiful. We often admittedly complain we are living in such specialized society, but then perhaps the Raven's Progressive Matrices test shows us otherwise. So how is the contrast between the inner and outer worlds working out on an individual level, and its effects in both the personal and collective unconscious.
In other words, the environment has a measurable effect on IQ.
Thus, IQ is a result of both genes and environmental cues.
This makes sense. It is not surprising that the least industrialized countries have the lower IQ's.
Introduce modernity and the averages shoot right up.
Absolutely.
Yeees...? Or, could it be that modernity will not take off because of low IQ?
So, could this allso be a thing of a positive or negative feed- back loop ??
That has not been my personal experience. Quite the contrary. Engineers trained 50 years ago are much more competent than the ones coming out of colleges these days.
Exactly !
What is the answer to the dots question at 0:46 ? And how is it reasoned?
I believe it should be 5. The patern being (5,6,3) (6,7,4) and (7,8,"5"). Or when read vertically, everything is in numerical order still leaving the final space to equal 5. And the patern of add 1 subtract 3 which again equals 5. The only problem is, 5 isn't an answer..
@@mikerphone. Yeah 5 was my initial thought. But not available.
@@mikerphone. Let me know if you find something. Ive considered different pattern solutions.
Like superimposing the blocks in different orders and seeing which dots match or dont match. Seeing what happens if you add a dot or subtract a dot then rotate the block. Nothing.
@@abstractfacts B maybe? The number of dots in the squares go odd, even, odd. Only odd answer is B with 7.
@@abstractfacts i did as well
Why did I see a report last month saying IQ scores were falling?
Likely because propaganda in this age happens more from both sides and people the last generation, cut off at 2000 and before, were and are more willing to believe propaganda without questioning it. This itself could also be propaganda or have been created off of propaganda that was deemed correct.
Because it is, in developed countries. In Scandinavia, the scores leveled out, and started falling slightly, around 1995. In developing countries, it's still rising, though. The correlation between increase in height and IQ is very close, indicating that it may have something to do with nutrition; no causation has been proved, though.
@@erikjarandson5458 Maybe the people in developed countries lost the need to gain IQ due to political movements or other changes in society.
@@nlhn638 More likely, most of the potential gain in improved nutrition and education has been achieved. Still, no one knows for sure, so you may be right.
@@erikjarandson5458 IQ seems to be 80% genetic. This has been reinforced/buttressed over and over again. Nutrition and environment will only take someone to their genetic "limit" or fulfill their genetic potential.
I find it very hard to believe that IQ scores are rising in the 20th to 21st centuries! This is after working many jobs helping or waiting on the general public for quite a few years. Fascinating video anyway--thanks!
The Flynn effect is dead and gone.
IQ scores are rising because of *inflation*.
They're rising but maybe not up to your intelligence. The rest of society will always appear dumb to a minority of the most intelligent...But we're still human trying to survive to die like everyone else later on, intelligent or not.
New generation has a greater tendancy to think in the way IQ tests want you to think. That's why IQs are increasing
Iq increased but not the g factor. No one cares about iq per se ..what intelligence researchers care is the g factor or general intelligence factor that represents over 60% of the score in the totality of an Iq test. G seems to be innate and influinced by genes and it seems impossible to change. And g is falling as hereditarians predicted a long time ago. They predicted a genetic decline and it came.
Its because of the internet
I can tell that the first puzzle's paradigm is clockwise motion, but what is the solution to the second puzzle at 0:50?
I would guess that it is B, given that the number of dots in a square alternates between an odd and even amount as you go across a row and down a column of the matrix.
*The survival has evolved being totally dependant on the capacity of the mind.*
The more you know, the better you are equipped.
That appears to overlook that the selection process for acquired skills/traits will be social selection, and thus not necessarily select for things that contribute to survival
4:22. I focused and immediately determined that both circles were the same size. I must be a pre-modern villager. :D
Also watch Flynn's TEDTalk
What is the answer to the second matrix (the dominoes) does anyone know?
My guess would be B because as you move across a row and down a column of the matrix, the number of dots in a square alternates between an odd and even amount and so the last square should contain an odd number of dots in order to continue the pattern and the only answer that has an odd number of dots is B.
U can tell size perfectly by de focusing the lens
Personally I think the two types of thinking are metropolitan and rural, in a sense. I think that's a huge part of the divisiveness of late. The majority of both do not understand the other.
but is the ability to grasp abstraction inherited tho?
I saw that the circle on the right was larger, but knew in my head that they were the same size, weird.

@@NinjaRem09 I don't believe there is any point arguing with you.
Could we also make the conclusion that the internet with all of its abstractness has played a big role in uping the areas of this IQ, and that since there is more abstractness on the internet every day, and more people can access the internet every day, and that the internet showed up in the 21 first century, that this could be the reason that this increment is sustained or increasing?
Actually, in developed countries, the increase stagnated between 1995 and 2000, curiously coinciding with increase in Internet connections. Coincidence? I wonder...
@@erikjarandson5458 I would probably say it had to do with the people using the product. I feel it may have let people become lazy. There were also a lot of movements I feel that were based upon entitlement during those times as well. In another comment, you say (I believe it was you) that in developing countries, IQ scores are rising. Lots of developing countries have been rapidly gaining access to the internet. Maybe, since governments in those countries are against such movements and are more about wealth and control over the people, combined with the fact that we probably have a completely different internet than we did back then, have led to rising IQ scores in countries. Lastly, in developing countries that are trying to grade people and let the public have access to the knowledge, such as China, the need to become smarter is a present need for the people that live there who want to thrive or survive, where knowledge is valued over other qualities, or where knowledge lets you have access to stuff other people don't.
No way, because different populations use the internet for very different things.
@@davidolsen8291 Yes, they do, but almost everything, from font, has some form of abstractness.

In the correct version, answer C has 5 points, which makes it the correct answer (columns from top to bottom having 1 less point each).
I wonder if this is part of the political problem. Instead of addressing each issue as each individual person sees it, we tend to classify people into patterns of "left" and "right."
People have to be classified into left and right, because technological advancement drives modernism, but there are only two technologically advanced political groups: White males and Asian males.
The political philosophy known as Intersectional Feminism is just a coalition of Never Technologically and Never Scientifically Literate People engaging in politics because they can't engage in science nor technology.
I have a better question: why do we always see claims that "IQ scores are rising or lowering" when the score is defined to average at 100? If you want to talk about inflation specifically, you can always... huh... y'know... talk about it?
Im pretty sure the average in Denmark is 100-110 and in a country like China it is a bit higher. Basically the average IQ of people in a country is around 100. Its not like the test gets harder in one country and easier in a different one to get them all have an average of 100.
@@Munchausenification I didn't write "the average is _around_ 100" - I specifically put it as _defined_ . You may want to provide (decent) sources for your factoid - therein we can determine whether your 100-110 claim is the _actual_ (scaled) or _raw_ (unscaled) average
@@thstroyur You are right. I didnt look into the difference between raw data compared to the scaled. I can try and look it up though.

A and B are the same colour.
It's a bit illogical to say that IQ has been increasing - suggesting (to many of us) that people have been getting more intelligent - when the truth is simply that more people have become familiar with a thought process that is fairly specific to a particular lifestyle, and lifestyles across the globe have been changing. The tests are just measuring something that has been introduced to a greater number of people than it was before. The fault/discrepancy lies with the testing method and its appropriateness for human beings overall rather than an inference that intellect has differed.
We colloquially use IQ to mean intelligence in general, but that's not really what it is. IQ is a quantification of the specific mental ability linked to this kind of test. People take the test, and get a numerical score. IQ is beneficial to many mental skills, but it is not a measure of every kind of intelligence across the board.
Do either of you have children? And, if so, do you want what's best for them?
So, culture has impact on IQ preformance.
It's because everyone can practice that stuff on the Internet with free tests
It's true that you can improve the IQ results you get, but the changes are small. For example, most people won't jump +20 IQ points.

IQ scores are scaled based on average values so the average score is 100 just like always. Nothing is rising.
They mean the _raw_ scores, which are subject to "inflation" - too bad they can't bother telling us that now, isn't it? Accurate statements don't sell tabloid rags

0:50 The test was created so you wouldn't have to bring anything you learned in life in to it. That might be an ideal but it can never be the case. The rise in IQ scores can just as readily be explained by an increase in test taking skills as to an rise in intelligence.
I.Q. tests are fun and they have their place but their validity is limited. They rely on the subject understanding how to take the test and being motivated to have the test measure what the test is purported to measure.
I.Q. tests are measures but measure of what? Quoteints?
"Intelligence" is not easy to pin down. Could be knowledge, a list of facts or a set of skills. It could be the ability to complete a task. It could be the ability to learn. Knowledge and skills are easy to test, ask a question see if they give the right answer or give a task and see if it is completed. But learning? There short term learning, cram for a test, take the test, forget it all the next day. And long term learning, certainly long term learning is more useful but how can an I.Q. test measure that? Teach you something, wait a year and see if you learned it?
I.Q. isn't all that great of measure.
Having high IQ predicts higher proficiency in all of the skills you mentioned.

I.Q scores are correlated with some other measures, like income, especially at the lower end of the I.Q. scale. The correlation gets weaker at the higher end of the scale. Probably because whatever I.Q. test measure overlaps with a basic money making but I.Q. capture less of what is important for making lots of money, such as social skills and psychopathy.

@@myothersoul1953 How about the simpler explanation that higher IQ people have always been outnumbered by lower IQ people at a ratio of 99:1, and at least some of those 99 people are jealous enough to discriminate against them (often violently)?
Do you have children, O Soul?
Imagine thinking IQ is anything more than how well you can take a specific test lmao
Imagine thinking IQ can be demonstrated only on a specific test and not be applied everywhere else lmao
Imagine existing in the most scientifically advanced country in the world, which gives you access to RUclips and the internet (both of which can be used to understand IQ), and being utterly clueless about IQ.
@@davidolsen8291 Please use those resources to educate yourself lmfao
@@Tary88 thinking you can quantify intelligence with a standardized test of any kind is LMFAO worthy. You probably think the Bell Curve is credible science too, dumbass
@@dylandigby1776 Dylan, what's the number one purpose of an intelligence test?
Answer at 0:47 is B. Alternates number of dots odd and even in either columns or rows.
In other words, environment effects IQ. It's not purely genetic like some believe.
Literally no one who understands IQ believe that it's "purely genetic". The phrase "purely genetic" is used by liberal activists (who don't understand IQ) to clamor for more welfare for minorities.
The current scientific understanding of IQ declares the genetics and IQ cannot be separated, so the Black "genetic mesh" creates specific types of societies, while the White American "genetic mesh" creates entirely different types of societies.
Teaching Black Americans to understand, appreciate and work sufficiently to maintain societies created by the White American "genetic mesh" is largely unsuccessful, and always has been.
Maybe not genetic but it's too separate knowledge from intelligence. I've seen some American IQ tests actually feature general knowledge questions, so fucking stupid
It affects IQ just as malnutrition or trauma affects growth. There's far more evidence in favor of genetics than there is for the blank slate, which is why due to all the evidence (twins/parent-child,racial/separated children...etc studies) a great deal of the leading experts in the general intelligence field peg the ratio at a minimum of 40/60% environment to genetic. Think of it in terms of potential, just like being tall/beautiful/extroverted/friendly/more connected will often get you further than talent/skill/competence/smarts.
I play chess and I solve chess problems and I did some of those IQ test with shape and I often scored 140 IQ and most of the time above 130 and I don't think it really measure intelligence but just my ability of abstraction that come with chess training.
Please don't be racist in the comment section. This is only about IQ so leave it as it is.
What does this say about IQ test? I can imagine a 4 the grader in 2019 would blow a 9th grader from 100 years ago, just based off knowledge gap that would occur from 100 years of advancement.
The Flynn effect has actually come to an end.
Mimo Slavich source
an iq test from the 50s cannot be compared to an iq test from the 90s. that is just stupid.
to elaborate, the tests themselves have changed, it might be the same type of test, but the thinking going into making them has ITSELF changed, sometimes making things more intuitive, sometimes making things more obfuscated. more often than not, the changes make things easier to understand.
in other words, THEY AREN'T THE SAME FUCKING TESTS YOU IDIOT.
and no, i am not saying that there are not things that can be studied and understood by checking out the history of iq tests, BUT YOU CAN NOT COMPARE THE SCORES. hell, the tests themselves started out as biased racist bullshit.
IQ's are rising except for EU countries where IQ has been decreasing due to horrible migration standards.
@They Live You're clueless for how low mass immigration has been going on, Germany didn't accumulate 4m Turks in last 8 years, that process has been going on for 3-4 decades. Also IQs in East Asian aren't going down even at 1/5th of the rate it does in West and Japan which has 1/10th drop rate of France and 1/8th of Germany is known for not wanting immigrants and refugees.
@They Live You just went Alex Jones with theories in order to avoid most obvious reason for not only IQ drop but rapid IQ drop in West.
@They Live so it's immigrants after all.
iq tests are getting dumber resulting in higher scores
Everyone is getting smarter and soon there is no fix our cars or be a plumber.
I wouldn't say people are getting smarter, social media isn't particularly a good thing in terms of benefitting our brain :/ This'll get worse and worse if we don't change something...
@@loukask.9111 do you have any studies to back this up?
There will always be mechanics and plumbers as long as there's a demand for them. If there's no plumbers the first person to do it will be able to charge extortionate rates and others will follow.
Because tests are getting easier.
Cuz I keep breeding
lol
Rising ?? HAHAHAHAHHAHAHAHHAHAHA... I beg to differ.
Love my low IQ brain
*It's simple!*
IQ is partially genetic and partially generated by nurture and education.
People all over the world have gained access to more and more knowledge. It's rising, but off course this will reach a limit in some time
Because IQ-Tests manly show how good you are at IQ-Tests... Or it is just me getting smarter every time I take on.
I don't understand why anyone would give this video a thumbs down. Even if you have issues with the IQ test and how it has been historically applied, the topic is interesting. Since Epstein highlights the marked distinction between those who are exposed to modernity vs those who are not, it does illustrate that a large part of IQ is highly malleable by environment. Therefore, for those who have problems with the notion of IQ being somewhat genetically determined, and the negative political, social, and economic ramifications that accompany this assertion, Epstein's presentation, of the highly influential role of environment, does give you a powerful argument against those who use IQ for more nefarious aims, such as racial discrimination.
Link in IQ test scores rising and Democrat rule changing...
Link on evolution, inherent knowledge with time, and IQ scores rising, or Democrat Rule not increasing IQ test hardness, a practice practiced by more RIght-winged political ruler/leaders.
But also G is dropping at the same time.
IQs rising?? Come have look at the teens and 20yos working at the business where I work. They may have some "book smarts" but their "work-smarts" are such that every day they awaken with memory of what they did and were told the day before completely gone, LOL.
Yeah but look at their world view and how much less susceptible to propaganda they are then older generations. Boomers got so wrapped up in McCarthyism that it took 60 years for our country too ALMOST be able to have a honest conversation about socialism. I say almost because no one is this country is actually pushing for worker owned means of production, but we are talking about social programs finally.
If it looks like IQ is increasing, then the test is not measuring the right thing. This presentation goes against other research, and the general decline in general intelligence since the start of the Industrial Revolution (as documented by Hutton and other researchers). The only places where IQ is truly rising are relatively isolated communities like Hong Kong and Singapore, where there's no Socialism. Yes, there does seem to be a connection. The environmental component to IQ is 20% at best, and the genetic component is at least 80% (latest figures). When the least intelligent are paid to have kids (the unfortunate side-effect of Socialism), and the professional women (arguably the smartest women) are childless, the future doesn't look good.
Damn socialists making ppl dumb
and yet we have Trump
@@Ren33469 Maybe we can send them to the moon. It would raise the IQ in both places. Maybe.
@@Ren33469 Kind of like Escape for New York?
Because people are figuring out the answers, it doesn't mean we are getting smarter.
R u sure those tests aren't going up because people paid for them or did you forget about that??

@@ILikeFeelingElectric He is a Christian(snort) crackpot who waffles off in real life nearly as much as he does in his books.
His notions on IQ are hilarious and exposes the underlying pseudo scientific bullshit underpinning psychology.
As a 'hard' science major i always find describing psychologists as scientists far fetched. They are glorified chatter boxes who find wisdom in the writings of mad men.
