How DNA Makes Us Who We Are | Robert Plomin | Talks at Google

Professor Robert Plomin is a leading behavioral geneticist who works at King's College, London. He has published more than 800 papers and is one of the most cited psychologists of the 20th century. He argues that we need a radical rethink about what makes us who we are. Drawing on a lifetime worth of research, he makes the case that DNA is the most important factor that shapes us.
In this talk, he discusses his new book, "Blueprint: How DNA Makes Us Who We Are", outlining the data behind his science and how twin studies help with reaching his conclusions.

    Excellent talk! Regarding whether people are alarmed about genetic probability, I would say that people intuitively know that genes play a large part in our lives. People say, eg, that she is as beautiful as her mother, he takes after his dad in sports, she is good in school because her parents are smart, he is no-good like his father, etc. In professional basketball, most people will say that Lebron James is genetically gifted and that an average player even with an enormous amount of training will not be as good as Lebron.

The guy wasn’t saying genes could be modified but that either people would choose certain polygenic score embryo or that protéines could be created to get the same effect that some polygenic score holders would normally have. It’s very similar to what Plomin himself said : the knowledge could be leverage to give more to kid who have less and not necessarily to wipe them out. All in all, a very interesting talk.

    Speaking about actual biological differences is fine. Pretending that genetics supports racism is the problem (and he clearly does not do that). Modern genetics has debunked the whole structure of racism that was erected long ago. Race has no biological basis. There are no genetic characteristics - even alleles that control skin color - which exist in every member of one "race" but not in anyone of another "race". It sounds like you have not learned enough yet about the findings of modern genetics.

Your second point (no genes found in one race but not in another -- not strictly true, but mostly true) is an irrelevant straw man. In humans, other animals, and plants, racial differences are in suites of traits (or alternatively suites of genes), that is, genetic frequencies, and have never been determined by one particular allele that differs in any invariable sense. Thus, you are attacking a position that nobody has ever held, not even Hitler. The reason they are races and not species is because direct or indirect gene flow keeps the boundaries a bit fuzzy, and this is true among all races, not only human ones. Races are similar to languages. It is sometimes hard to nail down the difference between language and dialect, no language has any grammatical element that is unique to it alone, and languages also change slowly over time, yet no one denies that languages are real things that actually exist. And you could say the same thing about families, yet no one denies that families actually exist either. Americans' obsessions about race, exported to other western countries, have made them all nuts who have lost touch with reality on any matter related to this particular natural phenomenon.

    "Grit" is most commonly measured as a personality trait labeled "Conscientiousness." Like IQ, it is predictive of educational attainment and the associated genes, whichever they are, likely are declining in frequency at a similar rate. Although self-reported Conscientiousness scores are only about 50% heritable, when you reduce the self report bias by averaging together the scores provided by five different assessors, the heritability rises to over 70%, similar to IQ.

    You should focus on what you are best at. Testing might help you discover this. Notice that this debate is not heated because of the conclusion's possible effects on individual choices. For most purposes, those individual choices will not change very much. It's all about public policy and that is what makes this debate so contentious. Public policy in all western countries, and probably world wide by now, is based on the assumption that humans are interchangeable parts, that all human differences that matter enough to care about are the result of environmental variables that can be, and are being, manipulated by the managerial state. If the geneticists are right, then those policies are misguided and counter-productive for society as a whole and in a rational world would change in very substantial ways. That is what makes the debate so contentious and the employees, beneficiaries, and ideological advocates of the managerial state so determined to suppress this conceptual challenge to the status quo by any means possible.

    So the general take home message is that genetically identical people (identical twins) look (the what) very similar and are ( personalities & intelligence. The whom is also a what,i.e., genetics) very similar, regardless of the environmental variables such as parents, teachers etc. And that people whom have been taught the more Freudian psychological model may feel that such a statement goes against their status ( Employment as a Freudian psychiatrists etc), thus deny the science. Also that many inheritable traits are probabilistic not deterministic. E.g., Sociopath's are less likely (probability) to express themselves under certain environmental situations than others. e.g., Social bullies are mitigated so that they do not gain any social status by derogating others and forming "harassment" coalitions ( less aggressive people whom "befriend" the bully so as not to be the ones whom are bullied).

    Parental income is also a function of parental IQ. It correlates about 30%. Educational attainment, which has its own GWAS score, is even more highly correlated. So again, you have the confounding by genetics. Heritability folks agree that part of the differences are environmental, but genes are equally important. The other school argues no group differences are explained by any significant genetic component, and that's a hard argument to make in light of what we now know in 2020.

Also, keep in mind that when you remove some of the noise from personality tests by averaging together tests from five different assessors, the heritability rises to a level similar to the heritability of IQ scores. However, personality is less predictive of worldly success than is general intelligence, so personality differences between rich and poor families are probably narrower than IQ differences.

    @@nycbearff Not quite. It is 80% in a shared environment, but if the environmental variance increases, then the genetic variance decreases. (And vice versa, the more equal the environment is made for all of society's members, the more heritable various traits become so that, if equal opportunity policies can be sustained for a sufficient number of generations, social classes will eventually evolve into genetically based castes with little mobility between them.) For example, adiposity is 70 % heritable, but if a fat person adopts dietary and activity habits that are very far removed from the average person in his culture, then the genes will respond to his new environment. If dietary and activity habits in the general population become much more diverse, then heritability measures would fall because of the increased environmental variability (while less variability would cause heritability to rise). Subsistence farmers in New Guinea were all very lean when first discovered, even though the heritability of body fat must have been at least as high, and probably somewhat higher, than in western populations. As some of them began to move to town and adopt modern habits, they got fatter, while their kinsmen back in the villages remained lean. Same gene pool, but the environmental variance had increased among them, forcing the heritability to fall for purely mathematical reasons.

    Findings indicate cognitive abilities are greatly shaped by early exposure to spoken word. People who experienced neglect or isolation in their most early formative years and therefor were not exposed to spoken word are far less cognitively capable than people who were. In fact, MRI scans reveal that regions in the brain responsible for different cognitive functions were adequately developed in people were exposed to regular spoken word in their earliest develpmental stages and people who didnt experience frequent exposure to spoken word in those stages we're underdeveloped in those regions of the brain. These differences were substantially apparent in achievement in later years. It was particularly apparent in academic achievement. There also a counter stance which is detailed in the books mindset and the brain that changes itself which debunk neurological nihilism.

    I just finished watching the "Three Identical Strangers", the documentary that he recommended watching only the first half of it. The reason he probably why suggested to watch only the first half of it, in the first half you have a perfect picture of Polmin's so called science, you have 3 triplets, separated at birth, one placed in a relatively poor family, the other two in a middle and rich respectively. In the first half of the documentary, the three seemed to be very much alike, same pattern of of life. To Plomin's bad luck, I also watched the rest of the documentary, only to find out that nurture played THEE most important part in their lives, sadly led to the loss of the life of one of them. People like Plomin are political, very much like Charles Murray. They stress on "genes" while playing down the important role of the environment. In here, Plomin didn't even mention the environment, only one line on his slides saying something like minor, random environmental role. Both showed up on Sam Harris' hilarious podcasts, with Murray, Sam suddenly turned to things like "fatherhood" and "reading stories" for his children before they slept, while funnily stressed on genetics. Sam Harris, perhaps to attract more people and hence make more money, speaks of "group intelligence" nowadays. Pathetic, really.

    What the fuck happened here? Sorry bro, but this was the exact opposite of a smart statement. You are using here the similarity of the arranged digits and comparing it with the numerical value. That's nonsensical. It is if i was to say comparing different metals by their density is misleading because cobalt (8,90 g/cm³) and copper (8,96 g(cm³) are 99.3% similar in density but their color is 100% different. But that is not the point. The optical appearance is not important and not the point. Humans share also 95% of the dna with hogs. And if you look closely you see that the majority of body functions are the same. But still there is a lot of difference especially in appearance. The human genome has 3 billion base pairs. Even 1% difference means 30000 different information points within the DNA. PS: With a numerical reference point (at your comment 1 Trillion) as 100% you can't measure similarity and end up at a sum greater than 100%. If things are 90% alike they can only be different by 10% not by 100%. Its like saying the probability of x and y in a coin toss is 70/70.

(Prof. Plomin himself goes on to discuss big effects of small differences from many angles). but your example of density is not about numerical value of the decimal place - so not even comparable to the original example... nor should we expect density to encode color in such a way. and how did you get your measure of similarity anyway? there is no standard measure for similarity. it's just a loose concept. I could devise a measure which, for a large enough dataset and with enough variance, could easily sum to greater than 100%. say; abs(average - (abs(deviation)) / average, summed for all variables.

Second: I don't know enough? :D Sorry but I'm a university trained CS and your "analogy" about bit code is also nonsensical. He was not talking about binary arithmetic. He was clearly talking about decimals as you can read for yourself. Also: When people say "DNA is like code" it is only to talk to people without a scientific understanding of genetics and statistics. To take that literally would be catastrophic. The fact that numerical shifts in one direction change the represented value exponentially is not a natural law. It is simply because humans defined it that way. Different arithmetic systems such as decimal, hexadecimal, binary etc. are constructed by humans. DNA is not constructed by humans. "I could devise a measure which...." Well, that's why we use normed vector spaces in math so that we can measure objects in a comparable way. And still he was comparing the numerical value with the observed appearance of digits, which is nonsensical. And his point was "Mimimi, it is misleading to say things in a way I don't understand". I responded to this and his nonsensical analogy. I was never making a point that "small changes" can't have a "big effect", because words like "small" & "big" are not used in scientific language unless everyone knows what it precisely defines.

And the fact that you ignore my point about him, coming up with 190% out of nowhere tells a lot about your intention to respond to me. And still with your own "measure" you completely ignore what he was trying to say. Of course you can have instances where 100+% are possible (Growth in value for example). But to say that something can be 90% similar but also is 100% different is nonsensical because you still reference only one object. Don't feel offended. I disagree with you, which is different from not respecting you. If you have knowledge about the scientific method you should use it to articulate yourself better.

    With the woman who raised a chimp from being an infant, to when he was an adult male, the the changes towards aggressiveness in adult males vs. the nurture of being raised as a child, - such was what went on with the chimp who attacked the adoptive mother’s best friend who bit off her eyelids, nose, lips broke all her facial bones, bit off all her fingers with the exception of one thumb - so if one were to apply genetics vs. nurture, in the end the wired in biology totally dictated the outcome. Even when we say, “do not adopt chimpanzees”, someone is going to find a way to do it anyway. No matter, belief about nurture vs. genetics, is such a strong conditioning, that even after her best friend’s face and hands were destroyed, this adopted mother or owner of the aggressive chimp said if she could go back and choose whether to adopt a chimp or not, she would have done no differently. Some cannot or will not learn from mistakes they make, they think life should be what they want it to be, terribly naive. In comparing intelligence racially, we have mostly a Black population which is mixed race mostly, and may be darker than Caucasians but they are far lighter than those who are not mixed race in Africa. If a study is done how will they create a sample to test anything when people are going to be interested in the science to learn the difference in what happens in racial mixture, and the effect is not on the individual studied but on what would happen if the results were handed to read on MSNBC, and there would then be a riot. It could be that the study was to understand even though Black children are part White, the gene which makes them largely lactose intolerant seems to always be inherited. How about the effect on having diarrhea constantly would do to your ability to learn! If you put the American Black person in Africa, the tribe, being 100% Black might not accept him unless he was famous as did the tribe Obama said his father was from. Actually, it takes a lot more mixing of White with Black to get a man who has such a light complexion and since his mother was not part Asian, where he inherited features that made him share those features. He almost looked Filipino. Would love to see his DNA breakdown for where his ancestors came from. Once again, it would be interesting but the subsequent rioting would not be. Dr. Ben Carson’s mother was determined to help her sons achieve in school and took her boys to church and from a mother who had no husband’s involvement in the home, both her boys graduated college and have achieved tremendous things. Dr. Carson’s brother is an engineer. So in this case the mother made her sons read books and give her book reports, they became interested in learning and in the church that they attended, Black people were well received and in positions of teaching and also being pastors, so they had role models for men who were worth looking up to. So in this case, the environment was the big difference. If Black people are no longer forced in schools to drink milk, you get another doctor, Dr. Milton Mills and he is brilliant too. You cannot achieve what you can achieve if you are perpetually kept sick. What should be studied to help the people who are here, is if Black people live more successfully in terms of healthy eating some of the plants eaten in Africa so that they do better in health because they are more adapted to these foods, then they can achieve more in education and such a study would be much better received, hence no riots. People respond much better to everything if they are well. The sad fact is that many Black people do not still, even make it to retirement because the Standard American Diet is quite frankly, more lethal to them. I have had many friends who are Black, I am not against them in the least, but they have had a horrible past in this country, to help them get well so they can live as long and be in good health, their academic achievement will also improve. Both the Black doctors I have noted are both vegetarian/vegans. They got away from being sick and look what they achieved. They are two of the most positive people I have ever heard speak and as far as racism they are not, they are inclusive to everyone. But they are WELL. Lactose intolerance is basically absent in White Europeans but not all, if you inherited DNA because you are related to Genghis Khan who share his DNA all over Eastern Europe, you could be like me, as allergic to dairy products as a Black person. However a White person with a reaction to dairy is sick differently: chronic constipation, vs. chronic diarrhea in a Black Person which is a more serious condition as people generally do not die from constipation but it does not mean you are well. I do better without dairy also. Both conditions: diarrhea and constipation do have a similar effect on leaky gut, both are absorbing toxins the as the intestines are not processing food well and pathogenic bacteria are making their way into the blood stream. It is one thing to offer other kinds of milk at school but it is almost like this, most people think dairy is healthy unless they got sick from it. In the long run dairy is causing breast cancer and prostate cancer in later life but White people survive this more than Black people. Black people do not need to be poisoned in the school lunchroom. If a parent does not want milk served or has a doctor’s note, that should settle it. I see no reason why we have to be married to milk. Children who drink water with lunch are just fine.

    He does talk about it (indirectly) when he discusses the influence of "idiosyncratic effects" that by their very nature cannot be systematically measured (Plomin's "dark hypothesis"). So the second big finding is this one 15:01 I just alluded to that the environmental effects are 15:04 important, but they're not [nurture] 15:06 in the sense of systematic effects of the environment. 15:09 Adoptive children-- a third of adoptive families 15:12 adopt a second child, and they're genetically 15:14 unrelated to each other. 15:17 They correlate zero. 15:19 Whereas siblings who grow up together and share genes, 15:21 they correlate substantially-- 15:23 0.2 for personality and 0.3 for, say, cognitive development. 15:30 So for 30 years, people have been 15:32 trying to find out what are these mysterious factors that 15:35 make two kids in a family different from one another? 15:38 And it could be lots of things-- accidents, or illnesses, 15:42 or different peers, or the parents treating them 15:46 differently-- but after 30 years of research, 15:47 no systematic factors have been found. 15:51 And so I've come to the conclusion, 15:53 called the dark hypothesis, that the effects 15:55 are essentially idiosyncratic, stochastic, random, 16:00 in a word, chance. 16:02 So they're unsystematic. 16:04 It could be like Bill Clinton in his biography, 16:07 he talks about why did he go into politics. 16:09 And he says, it's because at 16, he shook JFK's hand. 16:14 See, that would be a good example of this. 16:16 I mean, that's not a systematic variable 16:17 you could measure very well.

The same has also been done for adoptees raised in families together with the biological children of the parents (shared environments between non-genetic siblings). None of these large and long-term studies have supplied much evidence of epigenetics having explanatory power for any behavioral/IQ variations. Respectfully, you should familiarize yourself with the actual science and evidence before making the claims and charges that you do here.
