based on my ability to understand this video, I have a low IQ.
sucks to be you
ROFL, same here..
kyle robinson nah nigga ur just dumb in general it’s got nothing to with you u incel 😂
You are not alone. Don't underestimate the power of low IQ people in large number
@Darth Maul the N word is what a white man called us and thats we call each other thats what makes us dumb
When I was 11 and took an IQ test I scored 113. I also had a lot of difficult things I was going through: I grew up poor, in Foster homes and violent environments. When I turned 19 and my life was a little bit calmer I scored 143. It was very surprising so I had to take the test again. I got a 144! I hate telling people this cause I am a little embarrassed and don't like the silly associations that come along with such a result. Furthermore, I am in constant debate about the validity of these types of tests and what that really mean.
I think the disparity was due to my environmental factors changing: my life had gotten better, I was in college and I didn't have to worry or stress as much about immediate threats.
My mother is not very smart. I don't know what her intelligence is and it is hard to ascertain if her cognitive ability is diminished due to the stresses she grew up with (because she also grew up I'm Foster homes and had a tough upbringing , and it has really affected her mentally) or some genetic factors.
But hey I made it out of my predicament. Was able to travel and live all over the world and have great success up to this point. And I often wonder if that is due to my supposedly high I.Q., some resilience I gained from my harsh environment or was it a combination of convoluted luck and support from outsiders. Maybe a fusion of all those things.
But through my experience I do believe that our measure of success is due to how we react to each situation and the steps we take forward. Intelligence would help us parse out the paths that have higher possibilities for success. But also a myriad of other factors are in play; such as ones beyond our control, our ability to deal with stressors, etc.

@@friktogurg9242 thank you. 😀
AL: I would argue there is some merit in an IQ score but it is problematic. I came from a poor family and like you I was tested several times and the range was between 115 - 139. ( Real-world Intelligence? I'm somewhere in the top 90-95%) I quit High School and joined the NAVY, my education is largely informal (I read) and I am a lifetime student and critic of public education. Time and again I demonstrated problem-solving skills and earning capacity. There is no degree on my wall but I can hold my own in nearly any circle. My brothers too demonstrate above-average intelligence and we are retiring very comfortably in a Country Club minutes from the Gulf Coat of Fl. A few years ago a granddaughter called and asked about IQ. Her daughter scored a 128 and was placed in advanced classes. I chuckled and told her all is well. I am a GED $ millionaire, and one daughter is a GED multimillionaire, the granddaughter that phoned is also an HS dropout and she is well on the path to retiring before she is 40. She is drop-dead good-looking and wicked smart. Evidence genetics are at work. IMHO: I can teach an HS graduation class more in an afternoon about success than they likely heard the previous 3 years. The first lesson: Choose your company wisely! Cheers.
@@1Skeptik1 I also think habits and mindsets are extremely important. When it comes to hereditary traits, there is a genetic component; however, the characteristics we impart on others from our friends to family or even quick exchanges with strangers are immeasurably vital. And of course, how those people absorb and use what was imparted upon them, and vice versa.
There are some that seem to be born with some innate skill that affords them the ability to succeed even when the odds are stacked against them. And sometimes it can be perplexing when trying to figure out where that came from. Even how our brain develops in the womb has profound impact on us after we are born. For example if someone had more growth in their prefrontal cortex, it would most likely be easier for them to visualize scenarios than most people. And this could help them succeed in many areas, such as Mathematics; assuming they had a desire to learn it. Perhaps that aptitude would seem exceptional and cause people to believe they are of greater intelligence; however other areas of their brain may not have had as much development because of more growth in their prefrontal cortex; such as the Wernickes area, which consequently made language and speech more difficult for them...
I could go on and on and get more convoluted...just the subject of Intelligence is often times looked at in too simple of a manner. Intelligence and what affects it, how it can accurately be measured, what it really is, etc., is extremely complicated. And we still don't have a great understanding of what intelligence really is.
I would assert that the disparity might actually be more to do with your age. Just like how our physical body goes through a transformation and significant growth during puberty, I would assume our intelligence does as well. At least in my personal experience this seems to be true. Carefully looking back at my school years from 1st to 6th grade, I was, for the lack of a better term, quite dumb(relatively speaking). But the level of understand that I had during my class in the years that followed significantly increased along with my grade. I would catch the smallest of errors that teachers sometimes make or quite often corner some of them with a topical question that they couldn't answer then proceed to answer it for them. No significant environmental factors played part in this shift. Regardless, I am almost baffled that people would not consider intelligence to be primarily driven by genetics. When almost all physical traits rely on our genetic makeup, why would you assume that intellegence is something drastically different. Of course, the two shouldn't be lumped as an identical phenomenon and that any metaphysical truth dealing with the brain naturally implies a complexity that is yet to be discovered for the time being. But my main argument would be that the general direction in which intelligence is driven by genetics follows that of its physical counterpart. Well, I just realized that I'm meandering with this reply without giving much substantive argumentation but I am quite literally burning time at the moment so I will just leave it at that. Maybe I will take it a bit more serious and flesh out my arguments if anyone is willing to engage on this topic.

Duncan Crow that book sounds interesting

Yupppp
Fascinating. The most interesting part is how highly intelligent people create environments that propel further increases in inherited intelligence. (5:20)
That's just his hypothesis. He's not sure if that's true or not, it's an open question. The problem is that over time, the differences among individuals in regards to intelligence is caused in greater proportion by genetic heritability, which means that environmental factors become negated. However, this is counterintuitive. He proposed that the individuals benefiting from positive environmental factors only benefited because they were already heritably intelligent and placed themselves in these environments to further and confirm their own intelligence.
@@b4u334 it's even more significant than that.
When you equalize chances of opportunity by a secured environment like yours (health system to prevent and treat diseases and traumas, plentiful and constant access to supply to eradicate undernutrition, compulsory participation in a free public school system to ensure good intellectual development and the assurance of acquiring the basic skills to participate in society, sanitary habits over everyone and especially children (no smoking, alcohol and drugs during pregnancy...) an so on...), it maximize consequently the expression of the genetic differences between people since practically no more environmental factors can interfere with people cognitive development.

Stands to reason. Practically everything else about us is influenced in some way by genetics, so it would be strange if intelligence wasn't.
And: Intelligence testing is contentious "for some people" - a nice way of putting it.
Nobody cares... Because true intelligence lies in understanding genetics and human conciousness and then being able to modulate anyone, like making someone run as fast as bolt or play football as good as CR7 or be a 50linguial or be a great entrepreneur such as musk or be a great songwriter as sheeran or just anything without changing there basica conciousness:
But no one's smart enough to understand genetics and human conciousness

@@ecurb10 You care because you're mentally fragile. Imagine needing affirmation that your so called genetic group is the most superior for intelligence. This is your own insecurity
Genetics are everything. Life is about having the best genes and competing for the mate with the best genes. If intelligence is an evolutionary adaptation that allowed us to thrive, why wouldn't intelligence be inheritable?
This is literally not true lmao. Did your genetics determine this stupid comment?
Matthew Jones it clearly determined yours and the fact that no one liked your comment shows you probably won’t be passing them onto the next generation you pathetic incel 😂😂😂
somehow nature has a wicked plan, seen too many cases of mental and physical issues if two high intellectual individuals mate.

Momo zzz it’s basic biology you Marxist.
I just finished his book entitled, , "blueprint: how DNA makes us who we are". It was very interesting. It helps to understand a bit about statistics because he makes countless references to certain statistical outcomes in the book. He is a proponent of using genetic data to begin to identify the heritable propensity for certain mental illnesses in order to improve upon historical psychiatric methods of diagnosis.
The book makes a lot of sense. But it also seems to show that even genetic testing can only go so far in explaining ALL of the variances in human behavior. But it can explain enough to make it worth doing.
thank you for sharing it!
The more complex a topic is, the more likely it is, that people only will find what they were looking for in the first place.
One of the reasons all people never have been nor ever will be 'equal'.

Genetics are one the biggest role to success, that's my personal opinion.
www.ncbi.nlm.nih.gov/pmc/articles/PMC4711841/ All this estimates are bullshit. No genetically reliable proof of heritability of IQ or (g). The only stidies that have high heritability estimates are environmentally confounded twin studies and ureliable GCTA datas. So no proof so fare for his arguments.
@@sounkoumahamanetoure4607 why deny reality? MZ twins raised apart have extremely similar IQs. Adopted siblings are no more similar in IQ than two strangers randomly selected off the street. People differ in general cognitive ability due to differences in brain structure, and genes build brains. None of this is controversial if you think about it for more than 10 seconds.
If genetics plays the largest role in intelligence, how can it be *your* opinion?

To end world poverty we have to understand human prosperity which means we need to understand human differences which means we need to end society's taboo. Debate on human differences isn't hate! It's an important part of science!
I'm from a third world country where and I completely agree with you.
I would like to practice eugenics in a global scale.
What does it mean 'to end society's taboos'? If you're saying that somehow a BTS member breeds with a black girl is going to cause indifferences and ends world poverty then why is it that in developing world countries where many people are of the same culture and have no indifferences live in poverty ? For example the Maya people live in huge poverty and crime rates so high?
1. Genetic potential is a factor in outcome
2. Genetic expression is what we do with the potential. This is easier to see and accept when we look at machines. I have a very powerful computer on my desk, i7 processor, maxed out RAM, etc. When working with large databases this helps me greatly. The programming or "code" determines the outcome to a larger extent in the quality of raw power. Most humans do not question and examine the code they are running.
3. Quality of outcome on a long time line comes down to examination of beliefs and actions and results. 30 years ago I was in a computer class, the hardware at that time was very slow... We had to turn off the calculations in the program and then run the program later when we wanted to see the outcome. (go get a coffee : ) MOST PEOPLE QUIT prior to hitting enter. Fat people can become thin, poor people can become wealthy, etc. It requires more effort. The exception is below the threshold of minimum level to play.
4. If the machine "crashes" before we get the answer due to a shortage of computing resources you never can get the answer... YES, some folks have a shortage of resources.
5. Have fun with what you have been given. Hack the program enjoy your life. Explore, Create, Grow.
6. The impossible just takes a little time longer : )
Your last paragraph hit it. That’s sounds more to wisdom! Having a high IQ don’t make you wise.
Every single sociologist: "Intelligence has nothing to do with genetics. IQ differences are down to social differences and environment. It's not inheritable."
An actual geneticist: "Intelligence is inheritable."
Is this actually a widespread belief among sociologists? Do you know a lot of them, are in a related field or somthing?
@@petarivanovic2297 Yes.
Heritability is not the same as 'inherited'.
Well I'm a sociologist and I beg to disagree. We do take biological factors into account whenever they meaningfully contribute to subject of the research, but the thing is, genetic influence on intelligence is outside our field of expertise and is still debated on in gene scientist circles, and as such we still operate on assumption that genetic influence is negligible.
Heritability means "some kind of genetic component". He said in the video that at most 50% of our intelligence is explained by genetics. Which leaves the other 50% down to environmental factors like education, nutrition etc.
Surely this guy has been blessed by his ancestor's genetics, in body and mind.

But there was more to it. We were presented something new, no way even he heard or knew about it. He picked up faster than any of us. -- And of course, he became a doctor too, just like his parents lol....
My mother couldn’t even grasp the most basic multiplication, nor did she in her 30+ years in America, managed to learn how to string two English sentences together. I live with the anxiety of knowing that there may be, because of her low intelligence, a natural limit to what I can learn.

The teacher could identify the intelligent student from low and middle income parents, remove the student from the classroom, and place the student in a high quality independent study program. This works because it worked for me. Individualized education with independent study for intelligent students works, and can democratize education.
The can’t do that! It would mean you’d actually get educated and not indoctrinated
Actually the average IQ seems to be going down nowadays; and different groups definitely have different IQs.
maybe because iq is not intelligence
A very good point that intelligent people will tend to seek other intelligent people/environments. This will again further their collective intelligence. If we find that our environment lack the stimulus that we seek, we will change it. However i do believe that we have different kinds of intelligence e.g Math, Social etc. Meaning that the intelligent problem solvers will tend to seek more difficult math/problems to solve, while emotional intelligent people will tend to seek out more complex, and interesting people, perhaps challenging their point of view.
I agree 100% with you!
yess I see this all the time irl
I am very struck by your comment and I agree with the fact that people are guided by the search for environments that are related to their type of dominant intelligence.
Formal IQ tests are broken down in to different components. So, the things you wanted are assessed on IQ tests. A person may do better at a certain set of skills and not as well on a formal IQ test. Also, there has never been any objective data compiled to study "emotional intelligence."

@Adim Att Why do you say that? Has research shown this?
I have a hypothesis. A common theme is that human DNA is highly regulated; a lot of non-coding DNA is regulatory DNA. As we age, we experience increasing amount of environmental influences that increasingly favorably regulate inherited intelligence DNA leading to an increasing contribution of genetics to our intelligence. This could explain the increasing influence of genetics on intelligence as we age.
"increasing amount of environmental influences that increasingly favorably regulate inherited intelligence DNA leading to an increasing contribution of genetics to our intelligence" can you explain this part
doesnt higher invironmental influence impact who we are even more than less invironmental influence ?
Could motivation to learn be a factor? Some people don't really care about learning, some are insatiable learners. But is there a limit to what someone is able to learn, even if they really want to learn it?
Great questions! Individual intrinsic vs. extrinsic motivations I'm sure plays a part.
There is a study that mentioned that people with higher IQs are insatiable leaners and will find new things to learn causing some to make discoveries
Motivation is not cause, its the effect.
I believe there is a limit in learning. When you hit the limit you can still learn new things but you start to forget older things.
There is a limit to how much data the brain can store.

@Kent Horvath There is absolutely 0 evidence for multiple intelligences. Personality or physical abilities aren't intelligences, and all of that variability in ability is already explained by the general factor of intelligence.
Kent Horvath I have a bachelors in psychology. The Multiple intelligences hypothesis has never seriously been replicated in any study, it’s nonsense.
@Kent Horvath I can read studies, as can anyone else.
If you can link me even one study on multiple intelligences and a working neurological model that replicates, but you won't because there aren't any.
This is why Forrest Gump was worried about his son inheriting his genes. :P

There is a 100% overlap between people who argue against this and people who associate being “smart” with being “good.”
They want to think “dumb people” are “bad people.” So they must CHOOSE to be “dumb.”

Genetics determines how you start, not how you finish. You may learn quickly but with the wrong attitude you will not go far. You may learn slowly, but with the right mindset your compound knowledge will take you far. This has been proven by neuroscientists. The brain may not physically grow, its connections does, improving your intellectual capacity.
To an extent. Self discipline is probably heritable. Social skills and success can at times mean more. The unabomber was very smart. Not to successful. Just a thought.
All personality traits are mostly heritable.
Exactly my thoughts 👏🏼
Keep coping boyo
Background and talent are everything, so stop.
First we have to accept that genetics are the very reason that we are intelligent. Otherwise you could bring our cousins like chimpanzees or gorillas to our level by education which obviously fails. So our intelligence is the result of evolution and that requires a genetic component. Secondly the Flynn effect is most likely the result of the liberlization of education and career opportunities to the masses after hunderds of years in which you basically were stuck with the occupation of your ancestors. So there were very intelligent shoemakers who had no opportunity for education or career. This changed after WW2. Then we had a peak of people now freed and to search their place in live and to choose partners which were on their level. This produced more of intelligent offspring who themselves chose their opportunities. But this is obviously not meeting the rates from the first years.
Additionally, we need to take into account that better nutrition has followed the same curve. The brain is a very expensive organ from a nutritional point of view. Higher protein diets undoubtedly have had an effect, and have permitted individuals to maximize their biological inheritance. Also, over that same period, the average height has increased. Once again, showing the importance of nutritional improvements over time. Both brain growth and height have genetic limits. Good nutrition helps us to reach those limits.
In Communist Russia, back in the 1930s genetics (along with cybernetics) was a banned science, and geneticists were sent to GULAG death camps. It was not politically correct to say that genes exist or that genes play any role in human development, only the environment matters.
@@alexneigh7089 That's right. Genetics in the Soviet lefty shithole union would have destroyed all the myths and fakes claiming that races and ethnicities are all about the colour of skin. In Communist Russia interracial and interethnic marriages were pushed forward and mixed couples could get better jobs or promotion from the Party (hardly anybody would acknowledge that, but this was also the reality). So funny to see this happening again but to western world. I wonder how they ended up like this?:) In the USSR people had been brainwashed with the same Marxist propaganda till the fall of the country, never thought that Europeans and Americans would get into this shit.
The Flynn effect has nothing to do with Liberalism. It's nutrition, medicine, and literacy. The Chinese, despite living in a totalitarian 1984-esque state where millions toil like robots in sweatshops, experience the Flynn effect just the same.
interesting and expected that at least some of our intelligence is inherited. While some is from our environment. So, what do you do with that between maximizing human potential and freedom to parent as you see fit?

9:08 I have heard-tell that bad halogens like bromine have been added to table salt as a replacement for iodine. I would like more information on this because apparently not only did adding iodine to table salt in 1925 reduce iodine deficiency, it apparently increased general IQs as well. If iodine levels in table salt have been removed or significantly reduced, would this have caused the recent tapering of general IQs?
I am thinking that people are less intelligent now when I see social media posts- haha. I don’t have a high intelligence according to genetic markers yet I was able to achieve many of those things associated with high intelligence. Some markers on the DNA sequence seem to suggest that some people with higher brain volume are able to learn and analyze things differently. While in school I remember being put in average classes and thought for some reason I might be smarter than the people around me- haha. When it came to a class in geometry - I recall failing my first test and thought wait a minute - I think I’m smarter than this. I took the book home kept rereading and taking the practice tests in the back of the book (this is before the computer age) and voila next test I received an A. I had to ignore the situations at home that were pressing on me as a teenager- i.e. difficult bipolar mom. I am a senior and I am still interested in learning - I am learning a new language and it’s been very rewarding. This man is very intelligent.
A lot of the anger in this thread comes from an inability to handle nuance. Plomin says "intelligence has a genetic basis" and people assume that he is racist because one time someone that black people had inferior genetics.
Under no circumstances does that mean Plomin is racist. He's a scientist that is reporting some of the most robust statistics in psychology, which has been confirmed repeatedly through twin and adoption studies. The variance observed in intelligence between the races is widely believed by psychologists to be mostly accounted for by environmental factors, and I'm sure Plomin would be agree with their opinion.
Please actually think for yourself instead of becoming emotional and blindly reacting.
African Americans have a significantly lower socioeconomic status and SES has been correlated with intelligence. You are looking for any statement to confirm your racial bias. In no way did he say that there was no environmental factor...
I know you are not intelligent or educated enough to understand that correlation does not equal causation, and that is why it is hard to untangle genetic questions like this. There are certainly genetic differences between the races (e.g. skin color, prevalence of diseases), that does not mean you can attribute every observed phenotype to strictly genetic causes. There are epigenetic and environmental factors that affect gene transcription and translation, and the African American population suffers significant insult from their environments.
It is likely that there are genetic differences in intelligence between the races, but they are likely to be very small considering the short evolutionary timescale since they diverged. Please know your place and refrain from commenting when you don't know anything.
"People misunderstand what he says who are racist, therefore he is racist"
no.
"biology should apologize for the untold damage their discipline has done to humanity"

these environmental factors do have an effect on the willingness to learn. but genetics are the basis indeed.
When scientists say "black people are less intelligent than whites or east Asians are more intelligent than whites", those who take it to mean that they are advocating genocide or slavery are the ones who are the problem. There are plenty of such people on both the left and the right.
Very interesting.
incredibly insightful
I may need to watch this several times..
Actually it could go either way. He predicted that if we got rid of family advantages then heritability (as a percentage of variation) would increase because environmental factors would decrease. But if iq is genetic then smart families can give advantages, maybe such large advantages(to people who are on average smarter) that they overshadow luck and chance and magnify outcomes by iq.
I wonder how good are any types of IQ tests mentioned here, if the outcome can be effected with small things like what person ate for breakfast, his financial situation, how much sleep he/she had, etc... So many biological factors.
Very little correlation as iq tests are designed in a way that those factors won't make much difference
The outcome of an IQ test is rock solid, with only about +- 2 points of difference for the things you mentioned. Your concerns are a classic sign of slightly lower intelligence, because if you worry that you might not be adequate for a task, let's say coding, it usually means you aren't. People who code complex algorithms fast and efficient while doing the required math and mental rotations in their head effortlessly, they know they are adequate, they can feel their own understanding. You will never see those people being worried about their own IQ - their IQ allows them to know they have a high IQ
@@LjosiI took several intelligence tests on Google, and I took 114 places, another 66, another 140, and another 120. It's a terrible difference How can I know the correct one?
@@abdogames5975 those are not real IQ tests. Online tests are scams, even just falling for those scams reveals you have a lower IQ. Any reasonable person knows that only government administered IQ tests taken under timed supervision are legit (military, employment office, psychiatrist,..)
It seems to me that if the heritability of (g) increases with the age of the person, intelligence not likely to be related to environment. This would make sense, of course, as there's a mechanism (alleles) for the formation of the brain, but no known environmental influence on its formation _in utero._
Awesome video. New to this subject matter and this video taught me a lot
Interesting. So at the end, this guy is saying that in a perfectly fair world with no discrimination, the measured heritability of iq would be extremely high
It's only natural that removing other factors which influence [thing] would cause the remaining factor that influences [thing] to stand out more. If one removed all non-genetic factors which affect IQ, genetic factors would be responsible for all remaining variation. Likewise, if one kept society unequal but somehow ensured that everyone was genetically identical in all relevant ways, social factors would become responsible for all remaining variation.
Discourse around IQ is shot through with the nature vs nurture fallacy. The truth is that all observed behaviors are always 100% genetic and 100% environmental. They are how that organism responded to that environment. Change genetics or environment in the right way, and the result will have been different.
The next revolution will be the dumb vs the clever. Instead of 'power to the proletarians!' it will be 'power to the stupids!'.

Very intriguing topic. However, I am cautious when I hear the phrase "we find ......" without knowing how they found it. Always necessary to know.
maybe through a standard model of data and graphs of IQ tests of a variety of people ? Idk bruh they probably just came out with random s
@@lingzhao5719 maybe
Recent DNA studies have identified specific distinct DNA variations called single nucleotide polymorphisms, (SNP) linked to IQ. The challenge is that by examining a million humans about > 1000 DNA variations have been found that explain only about 10% of human intelligence. This means much more work needs to be done to explain all of genetic influence on intelligence. Each genetic variation explains a tiny amount of intelligence, e.g. 1 DNA variation = 0.05 IQ point. The biology is complex and the statistics are complex.
In school genetics play a big role,the holy grail of genetics is people being able to improve their intelligence through genetic modification,academic performance and creativity will improve drastically
education is extremly impactful, as big impact as you think genetics are. Motivation, role model, safety feeling. All of this literally determine how much a person is going to try and get interested at school
So it's similar to our job interest as Jordan Peterson points out that in society with more equal opportunity those genetic tendencies related to choosing job path are more visible and man tend to choose more masculine jobs and women more feminine jobs.

I read a lot - nearly a book a day. Plomin's book was the best book I read last year.
Mr Men books don’t count
@@summerrr1
I take it that this is some kind of insult. I had to look up Mr. Men. I'm still unclear as to what it is. I met a guy when I was in the army who read five books a day. It's mostly justly a function of how many hours a day you read.
I do read some small books. I read the Osprey Duel books (tanks and planes) and they are quite short. But I also read some full length non-fiction books like this one. This year the best such book I've read is by Charles Murray.
Does this mean that if someone is extremely verbally intelligent, they could’ve been equally spatially intelligent if they had developed that ability as much? Are there any genes that are just good for one intelligence but not the other?
he just said there's a correlation (known as "G") between all the categories. It just means that a person with high verbal intelligence is going to have a proportionately high spatial intelligence. For example if you had a verbal score of 7/10 then you wouldn't have a spatial skill of 1/10, it's going to be something closer to 7 like 5.
No, it just means they are likely to be beter than most people
there is a tendency which supports your question, it´s the g-factor if intelligence. The thing is that this factor mostly influences the speed we process different categories of tasks. If you see me doing a math problem I have never seen before ten times faster than the average person, you can expect me to be able to create a verbal rhyme at least 5 times faster than average.
But concerning the giftednes in the specific subjects, we do see the pattern of multiple intelligences. Many people who are able to talk almost like Goethe concerning their verbal CREATIVITY often cannot solve most university level math problems even after hundreds of hours of hard study.
Summary: So, concerning processing speed we have a universal intelligence but concernig originality we can proof Gardener´s multiple intelligence hypothisis. (Meaning a fast person in English will be fast in maths as long as we are only talking about processing what is already there. As soon as we enter problem solving land, people differ most often in their ability to excell in the relevant endavour)
Note the general intelligence is most closely tied to verbal intelligence, particularly the ability to perform well on analogy questions. Next down the line are the following verbal elements: vocabulary, reading comprehension and then grammar and syntax (to which sentence completion questions relate).
Hilariously I think they took analogies out of the SATs (if i remember correctly)
being born with a low iq is a curse. Especially when the fields you like require a high iq. Being doomed to work a shitty job because the happenstance of an egg and sperm fusing is torture. It should be illigal to have kids without being 100% sure that their genes wont make them dumb, unmotivated or neurotic. If it ever were to become possible id love to gene edit myself out of this living hell.

Same here. I'll a walking advert for genetic engineering, and what happens when mediocre people reproduce.
@@catherinebirch2399We actually need all types of people not just high IQ people.
None of us are doomed. There are plenty of people that are mediocre in intelligence tests, but are happy and productive members of society. You can do a lot to improve your lot in life.
Conversely, there are a lot of highly intelligent people that aren’t necessarily happier or contributing more to society. There are also traits like creativity and moral intelligence that are harder to measure, but matter even more.
If society is getting more intelligent, then why are we as a species more unhappy than ever? Maybe it’s less about standardly measured intelligence and more about personality traits that make us happier and contribute to the happiness of others in society.
Well done explanation! I wish other people would who think intelligence is not inheritable would listen to this.
It should have been named C.A. (cognitive ability) because the word intelligence has such a strong colloquial meaning.
Right...then the dumb people wouldnt even be offended lol
So so strong is the colloquial meaning you want to start changing words that mean specific things in the science community? Sounds like a great plan 😃😃😃😃😃
Ashkenazim have the genetics and IQ that surpasses others on average
It's ironic, they are oppressed into 'lesser' professions that require math and forbidden from breeding with non-Jews. The super-Jew was created by the anti-Jew.
His last point is very interesting. If we were to maximize the environmental effects for each person; that is, give each person all of the education, social benefits, etc. that he/she could benefit from, we would still have intellectual differences, but now those differences would be based entirely upon people's genetics. Heritability would then be very high. There is no way to homogenize the population's intellectual abilities. As it stands now, we can rationalize away intellectual differences by attributing those to differences in experiences and opportunity. How would people feel about themselves and others if they were forced to recognize that those differences where based entirely upon their genetic endowments? There would be nowhere to hide from that reality.
the most intelligent comment. You understand the video.
We all know what would happen, don't we
Agreed
I believe that we cannot control where we come from, by this I mean the genes that we inherit, even so we can improve our intelligence depending on the environment, people and information that we take in.

IQ is like height. It's genetic with a smaller environmental factor. A person whose genetics says 6'4" can grow up to be 6'2" with poor nutrition. But they will never grow up to be 5'6" and vice versa. Genetics sets a small window for what you are. Environment can only help you maximize within that small range.
how do you explain asian peoples coming to europe and suddenty getting taller than white peoples themselves. I have miultiples white / asian mixed friends that are taller than me. And im not small, my dad was 6.2 foot
What does he mean when he says heritability increases or changes? Is he defining heritability as something different than inherited traits? Also, I noticed his comment about stopping people from passing their wealth onto their children. That one will go over quite well.
@SlypherSpoons Thank you; so it maybe something of a progressive trait. Interesting.
I believe he means that, as environmental differences are reduced, genetic differences become even more significant in their effect on measurable long-term performance.
@@hermes_logios Thanks!
People's backgrounds, educations and experiences are different across the board. Is there a study that shows IQ test results of people of different races of the same age who all had the same educational background and got the same grades in school?

Very interesting. That's actually going to be the next thing I look into; intelligence/genetic effect on mental health and behavioral issues.
I'm verry clever and have a hih IQ. My mum is super proud with me.
Just to clarify he states that the environment we choose is based on genetics, correct?
No he says we start off with a small difference in IQ between individuals and that this has a heightened disparity over time (especially during childhood). He then suggests that this small difference in IQ guides us to stimulating environments, that are in layman's terms deemed as 'intelligent'. Like a positive feedback loop our intelligence is able to get to full capacity if the environment is optimal. This in turn has an effect on the environment we're in (more stimulating), and the way people perceive us, and, our motivations and positive associations with difficult problem solving. All of which in turn manifest itself in a higher ability to problem solve.
@@Sophia-ec5uy LOL
@Zach cash mate I'm doing a BSC in psychology and my understanding is pretty good
@Zach cash An issue with the studies is that they're mostly twin studies so assume that the twins have the same environments, which isn't necessarily the case especially for monozygotic twins as they may be different genders and in turn, this assumption poses issues for the research methodology/ validity. Also, the genome studies and twin studies are based on associations (correlations/ regressions) of phenotypes (e.g I. Q) with genetic similarities so can't directly suggest cause. At the moment it's suggested about 60% of your intelligence is genetically based and all this is through something called additive dominance which is where genes basically have a small effect but add up to create one phenotype (being smart/not so smart).
I love plomin, and I'm not saying intelligence doesn't have a large genetic element - but we can't discount how our environment shapes our genetics too (take a look at epigentics v interesting). I was just trying to explain a particular element of what he said in a way that I think was pretty accurate
@Zach cash so I suppose yes, in a way he's proposing that if we're naturally a bit smarter we seek out stimulating environments and this makes us even more smart in the long run due a snowball effect
But this particular idea is just a theory
And it has little empirical evidence
The research isnt racist.....those shouting racism are biased.
@@nollhypotes Please read Wikipedia page on Plomin, he does believe in differences in average is between different human populations to be at least partially genetic in origin.
You can argue whether he's right or wrong on that, but that's what he believes
@@nollhypotes Well, then, I didn't understand it that way, but Plomin might have simply contradicted the other things Plomin has said during his career.
He is one of the people who signed these conclusions:
en.wikipedia.org/wiki/Mainstream_Science_on_Intelligence
Please read every single paragraph of it, especially the last ones. They specifically address the racial and specifically mean group difference.
Again, you can argue whether he is wrong about it or not, but this is what he believes in as well as many other scientists "left" from him, i.e. the ones more on the environmental side of things, like, say, James Flynn do.
Furrowed Brow the conclusions may be racist, but blame nature for that. There does appear to be disparities in intelligence between the different races, and these disparities are likely to be the result of genes. However, that doesn't become an argument to judge individuals based on their race. Exceptions obviously do exist.
Tobias F citation for what? I'm not stating a fact but rather my conclusion. You should've asked me to provide reasons why I came to my conclusion. And what exactly is the evidence for the disparities being environmental?
Tobias F for one, I have yet to see any evidence for intelligence being influenced by the environment. Never have I come across specifics. If you can provide me with scientific, peer-reviewed studies that specify the environmental component(s) that adversely affect intelligence, I will be happy to be more open-minded. "The environment plays a role" isn't adequate enough for me. I need to know what specific components of the environment have been unequivocally shown to adversely affect intelligence. My default position must be what is existential rather than hypothetical. We have found genes responsible for intelligence. Thus, I am compelled to believed what is clearly proven and well-developed
Wish he would've gone into the hypothesis that heritability correlates higher over time because the brain is more fluid when you're younger and genetics have a higher impact than we'd like to admit.

"Heritability increases with equal environments" (11:20) I never actually thought about the gene x environment theory in this way - but it does make you wonder.... the whole equality of opportunity debate is centered around the fact that we will become more equal regarding socioeconomic measures but what if we instead actually cause a greater divide between people?
Say that we construct an environment in which we think we best cultivate intelligence based on previous observations (how does the environment look in families where brilliant kids are raised? how does the school environment look? etc). That environment would not be the best environment for everyone - it would be a highly specialised environment where people with high cognitive ability excel, leaving people of average or low cognitive ability even further behind. Maybe what we call "equality of opportunity" isn't equality of opportunity at all, but indeed a highly specialised environment where we put even more emphasis on heritage than before, giving a certain group of the population an enormous advantage?
So in other words, as long as low-intelligence races exist in a society, it will hold them back from achieving a society where intelligence is cultivated and valued and where human potential and technology will be advanced. Sounds like an argument against multiculturalism to me
I am suspicious about what we know about environmental vs genetic heritability. One thing I never see addressed is that individuals can get very different IQ scores taking the test at different times in the same few years, and whole groups can get wildly lower scores when they are under stress. This has been shown with seasonal workers. We also know that simply being in a lower social caste or class affects the brain by being either a long time lower ranked member of society. It's possible that many of our ancestors didn't experience that, because much social stratification in pre-history was cyclical or temporary.
Excellent talk - RP is so damn smart. Its disturbing that our society requires/rewards inherited intel more and more over the decades. Like gender race or baldness or weight - its something we can't help. See Yuval N Hariri's "useless class" problem and it is our biggest challenge as a society/planet.

I think that increased inheritability with age is mostly due to the fact that only by age of (roughly) 25 the brain developes fully. So measuring intelligence of not yet developed brain is like measuring the speed of car that is not finished. And it is not surprising that adults of the age 25+ show more than 80% heritability of IQ.
The analogy doesnt explain the percentage change at all. It only explains why measuring iq at the age of 25 ist the most accurate. The question is why the build plan of the car changes with age.
@@Alex-bl8uh it does. The build plan doesn't change, the performance does.
Also i don' think you understood what i was talking about. The measurement is accurate across the age, not just at age of 25, the heritability increases till age 25 and then stays the same.
That's why IQ tests are calibrated to specific age groups. The relative ranking of IQ remains the same. A child who has a higher IQ compared to his/her classmates at age 7 will tend to have a higher IQ compared to those same classmates at age 37.
@@nonono4160 The problem solving skill of someone with high IQ is very likely to be well above average. This ability is there at a very young age, kid who is very smart will find more creative ways to build lego blocks, another will perhaps be able to create a few pieces of a puzzle with a piece of carton, and coloured pencil if a puzzle stored somewhere isn't complete.
This problem solving skill will enable to solve more difficult problems later in life, for example some people can detect signs that something serious is causing their health issues and seek help at stage 1-2 of cancer whereas others are less fortunate and get a correct diagnosis at stage 4.
Heritability on the other hand increases steadily. A gifted person at 25 will perhaps regularly lose arguments with a professor 20 years older than him, but at 35 will be able to give a better account of himself with the same professor, because he has read more, has had more verbal duels with his peers, and his mind is more adept at forming thoughts that enables him to focus on the matter being discussed and quickly come up with counter offensives to whatever the professor throws at him. That's why a 50 year old person with an IQ of 135 will be a better CEO than he would have been at 25.
@@redshift8302 the thing i was talking about was the fact that the measurement of IQ showed that the degree of heritability was growing with age untill teh age of around 25 (which conincidentally is the same age when our brain fully develops). After that the heritability staus at around 80%.

@vvlmm I think even truer in metropolis because they are a true product of the DNA of their inhabitants.
indeed, genetics and education are the same if it is both given by your parents. But to know if the parents have a true impact on the intelligence of their childrens, we first have to know if intelligence is heritable. Once we know that, we can say what make a person. If intelligence is educational, then we have the possibility to re-educate ourselves and we can better understand why we are unable to do things that we thought were impossible to do because of who we are. And i dont trust scientific studies that talk about intelligence, especially when the guy seem confident about it and keep spitting words and words but no "?"

Education is cope. Intelligence is mostly genetics.

Which had parents who took an active interest in their education? How do we know which child's diet was nutritionally rich, and which child was malnourished? I could go on and on with this. There are so many hidden factors involved in a person's development that it seems somewhat foolish to put it down to genetics.
Genetics indicate potential. Achieving that potential depends on the factors you mention. (As well as many other factors.) It’s both.
You don't understand the measurement methodology.
The factors that you described aren't as hidden as you think they are. Plus, parents with higher intelligence will be able to read to their children and generally provide a better environment to foster their child's physical, educational, a d psychological growth.
