    Default Antisocial beheviour and crime is totally genetic for twin and adoption studies

    "Baker, L. A., Jacobson, K. C., Raine, A., Lozano, D. I., & Bezdjian, S. (2007). Genetic and environmental bases of childhood antisocial behavior: a multi-informant twin study. Journal of abnormal psychology, 116(2), 219."
    "Genetic and environmental influences on childhood antisocial and aggressive behavior (ASB) during childhood were examined in 9- to 10-year-old twins, using a multi-informant approach. The sample (605 families of twins or triplets) was socioeconomically and ethnically diverse, representative of the culturally diverse urban population in Southern California. Measures of ASB included symptom counts for conduct disorder, ratings of aggression, delinquency, and psychopathic traits obtained through child self-reports, teacher, and caregiver ratings. Multivariate analysis revealed a common ASB factor across informants that was strongly heritable (heritability was .96), highlighting the importance of a broad, general measure obtained from multiple sources as a plausible construct for future investigations of specific genetic mechanisms in ASB. The best fitting multivariate model required informant-specific genetic, environmental, and rater effects for variation in observed ASB measures. The results suggest that parent, children, and teachers have only a partly “shared view” and that the additional factors that influence the “rater-specific” view of the child’s antisocial behavior vary for different informants. This is the first study to demonstrate strong heritable effects on ASB in ethnically and economically diverse samples."


    Consider that measurement error is always a problem even with the most precise measurements (this study has the best measurements) and increase the unshared environmental variance in these studies, therefore that 4% of environment is actually entirely measurement error, definitely, and therefore the real inheritance will be 100%.



    https://www.gwern.net/docs/genetics/.../2002-rhee.pdf, page 27, studies on adoptees indicate that the shared environment, such as where you grew up, the family you come from and the friends that surround you, only count for 5% in determining the crime, but as it is written on page 25 in the age section "The ACE model was the
    best fitting model for children (a2 .46, c2 .20, e2 .34),
    adolescents (a2 .43, c2 .16, e2 .41), and adults (a2 .41,
    c2 .09, e2 .50)." and only a third of the sample is made up of adults, therefore the 5% identified in the studies on adoptees is actually an artifact of the young people included and in adults crime is 0% exact shared environmental (there is a 7% reduction from adolescence to adult in the shared environmental component, so the 5% is only due to included juveniles.) Additionally, criminal behavior has strong selective mating that overestimates the environmental variance shared, therefore it is assured for those who understand the modeling logic of twin studies that even in twin studies the shared environment counts for 0% in adults, instead of the 9% reported above. Measurement error due to the self-report of one's own criminal behavior used as measures and to the fact that in half of the twin pairs if one twin is discovered for a crime the other is not actually discovered, therefore that 50% unshared environment is just measurement error (in fact the first study mentioned using the much more precise measurements of the studies included in this last meta-analysis is in line with this absolutely certain point).



    Conclusion: antisocial behaviour and crime behaviour is totally genetic and 0% due to environment where do you come from and racial differenze are totally genetic

    Basically everything is genetic. The so called environmental factor is a scam.

    100% technically accurate statement; the environment that appears in twin studies is totally measurement error. And it is an absolute fact and not an opinion, so studies capable of reducing the measurement error to 100% would lead to 100% heritability estimates for all traits. On average only half the time if one identical twin has a disease so does the other, but this is totally due to so many misdiagnoses and misdiagnoses, the true rate of agreement for almost all existing diseases is close to 100 %. Twin studies show that income, views on women's rights, military enlistment, academic performance, depression, criminal behavior, self-esteem, musical tastes, and literally every single thing you can imagine is totally genetics. Today people are of a different mindset than they were a century ago and drastically richer solely due to the genetic superiority conferred by much lower inbreeding and inbreeding rates, which has resulted in a different mindset and vastly superior cognitive ability (Flynn effect) which allowed economic development and income to increase dramatically. These are not my opinions but as a matter of fact, I consider myself to be the most expert in the world on this topic.

    It's good to know the world's leading expert on the subject posts here at this forum. What's the typical sample size for twins separated and raised by different families? Twins are rare, and even rarer are twins adopted and raised in different families.

    Also, as the world's expert, have you read Judith Rich Harris' work?

    Interactions between the environment and genes affect development. Early life experiences determine whether genes are turned on and off or even if they're expressed.

    So to solve black crime and underachievement then we just need to throw a ton more money at the problem to improve the environment ?Not without transhumanism. Blacks went to being discriminated against to being discriminated for in affirmative action and set-asides but they are still just as much losers as they have ever been --just as low IQ, just as criminal and just as drug taking etc...

    In general criminals are myopic and stupid :

    There is . . . no doubt that the various races, when carefully compared and measured, differ much from each other,—as in the texture of the hair, the relative proportions of all parts of the body, the capacity of the lungs, the form and capacity of the skull, and even in the convolutions of the brain. But it would be an endless task to specify the numerous points of structural difference. The races differ also in constitution, in acclimatisation, and in liability to certain diseases. Their mental characteristics are likewise very distinct; chiefly as it would appear in their emotional, but partly in their intellectual, faculties.
    --Charles Darwin, The Descent of Man (1871)

    They [black Africans] seemed to possess "insufficient powers of reasoning" to discern nonobvious connections between moral laws and public welfare, and they lacked self-discipline; "Their utter licentiousness, not to mention unnatural crimes, is something astounding."--Charles Darwin, The Descent of Man

    "Their [black Africans] judgements are in error, yielding patterns of behavior that are pointless, if not, indeed, in complete opposition to the true welfare and happiness of mankind."--Charles Darwin, The Descent of Man


    Like other biological processes, intelligence must have evolved under the influence of natural selection.
    —Jerison (1973)

    ...it makes sense that intelligence is a component, at the group level, of a slow Life History Strategy. An environment that selects for lower intelligence is one in which you can “live for today” and pick the “low-hanging fruit.” A K-selected environment, on the other hand, is one in which restraint, problem- solving, and cooperation are required for survival. In that races are evolved to different ancestral environments, it makes sense that there would be race differences in intelligence and that these would be mainly genetic in origin.

    The discovery of these average racial differences in IQ has, not surprisingly, led to a great deal of emotional outrage. When American psychologist Arthur Jensen (1923-2012) reported in 1969 that African-Americans had lower average IQs than White Americans, he received death threats, security had to escort him around the University of California at Berkeley campus, and the police advised him to move house. When Hans Eysenck (1916-1997), a psychologist who had fled National Socialist Germany for Britain and who published on race differences in IQ, attempted to speak at the London School of Economics in 1973, his podium was pulled down by a “Maoist” student mob, and he was punched in the face. Many researchers who dare to enter this “forbidden zone,” have found themselves subject to a variety of tactics, including being fired, suspended from teaching, ics, including being fired, suspended from teaching, subject to biased or dishonest misconduct investigations (where conformers would be given the benefit of the doubt), unfair research appraisals, withdrawal of funding, public condemnation by their university, withdrawal of honorary university positions, removal from the university’s website (when such positions cannot legally be withdrawn), and, of course, mob violence or the threat thereof. This is true of many of the scholars whose work is cited in this chapter, including Helmuth Nyborg, Richard Lynn, Noah Carl, Linda Gottfredson, Michael Woodley of Menie, and Jan te Nijenhuis...

    Sure but the environment doesn't appear out of thin air so it is ultimately genetic too.
    You can take a Gypsy baby and raise him in a well-to-do non-Gypsy family and he probably will grow up to be a better citizen than his siblings who stayed in the Gypsy camp, but everything that made him different is the product of the foster's family genetics. Not his, but genes nevertheless. Needlessly to say, even with all the time, money and effort spent, he will still behave closer to his biological siblings than to his adoptive siblings.
    In short, people build and surround themselves with their own environment and what lead them to one type or another is ultimately the product of genes.

    I don't think you quite understand that. In 99% of cases it has to do with the action of external chemicals such as drugs and poisons. It's not about a kid who played lots of violent videogames becoming a violent adult.

    This is moving the goalpost. First blame schools, then resources and finally the families and neighbourhoods. But everything fails.
    Imo the most important part is that all the money wasted is the product of "white genes". To have a "good" environment you first need "good genes".

    Also, as the world's expert, have you read Judith Rich Harris' work?
    Should I tell a lie, that I'm not, to seem less socially bizarre, or should I tell the truth? Because the truth is, they are, on a very specific part of the subject, not the broad subject, I admit, but they are there. I'm like a high functioning autistic child who knows all the names of the stars but who if you ask him questions to examine the larger context knows very little, simply because the larger context doesn't interest me. Studies of twins raised apart usually include quite small samples, of a few dozen or barely a hundred pairs, in fact twin studies are done primarily on twins raised together, and they are perfectly consistent with studies of twins raised apart currently carried out and with studies on adoptees. Studies examining possible methodological biases caused by violation of the fundamental methodological assumptions underlying twin studies raised together have consistently demonstrated the perfect legitimacy of twin studies as a method for untangling the effects of genes and environment. Epigenetic factors do not seem to distort the heritability estimates according to the publications that have investigated this possible methodological criticism, the assumption of equal environments for fraternal and identical twins seems perfectly supported in the prenatal environment and also in the postnatal environment, as demonstrated by the fact that twins raised apart are indistinguishable from twins raised together, and as studies comparing the similarity of fraternal twins mistaken for lifelong identical twins show, that is exactly what one would expect from their genetic relationship of fraternal twins and not of identical twins. There would be too many things to say about it. Yes I know his work, it's the usual bullshit totally incompatible with the evidence.


    Everybody spews bullshit on this field. Even a fart of mine comes light years closer to reality than any researcher you'll mention, and I'm not saying that because I'm a pumped-up idiot, but because it's technically reality, unfortunately.

    This is the usual bullshit fed up over and over by people unable to contextualize the evidence. Epigenetic factors are themselves genetically predetermined for the vast majority, and the environmental experiences you speak of are catalysed by heredity. And adoptee studies and twin studies show that IQ in adults is 0% influenced by the environment you grew up in (shared environmental variance). Only the unshared environmental variance counts, but it is totally a measurement error because the differences between two people tested over time are the same as those of the same person tested twice. There are tons of studies on twins raised together, and some on twins raised apart, and they show that income, military enlistment, personality, religiosity, how one thinks about women's rights and various political issues, crime, food tastes, BPD traditionally thought to be drastically influenced by childhood environment, aggression, subjective well-being, and almost every single phenotype you can imagine from every category is 0% influenced by shared environment, and it is totally genetic. Every single statement I make is supported by specific publications and by their adequate contextualization made by me which takes into account assortative matching as a distorting factor.

    The only environmental component that is important in twin studies is the non-shared environment, i.e. individual experiences and due to chance, but this is totally measurement error either due to misdiagnosis and failure or due to very transient circumstances. Therefore stable and real inheritance for everything is close to 100%.


    Of course the usual cheesy bullshit is the first to get likes, because simple minds like things that are extremely easy to understand, no matter how technically wrong.
