@loaburime @charlesmurray I’m done wasting time with you. Yoi refuse to respond to any questions and you have some weird axe to grind against people you deem “racist”.
English


@___Branko___ @charlesmurray What are you talking about? I posted the article, asked you to check chatgpt with the math I laid out. Can't you read? Or do you just willfully ignore evidence your idol Charles Murray?
English

@___Branko___ @charlesmurray Ask the AI about the 100.5 IQ calculation and not the 99.5. Again I still need to update the essays throughout, but you can see now
Early adopted black interracial: 99.2
white(attrition corrected): 100.5
English

@loaburime @charlesmurray Do you ever reply substantively to anyone? I asked what by what testing metric and under what conditions you are asserting a. 1.3 point intergroup IQ gap. Stanford-Binet? or nonsense like Ravens Progressive Matrices?
English

@___Branko___ @charlesmurray Im not bringing in any new tests, its from the main chart from the 1992 follow up. I still need to update the other 3 essays to say 100.5 instead of 99.5 but Part 4 is correct
English

@___Branko___ @charlesmurray Throw the article in chatgpt and read what it says.
I corrected the white attrition inflation only. It reduced white adoptee IQ from 105.6 to 100.5 due to the 6.1 point inflation gap. The correlation r(T1/T2)=0.63 and the S.D.s

Read the actual article to understand what the white inflation was and how to correct for it
English

@loaburime @charlesmurray What you are saying is demonstrably false and unsupported by evidence.
By what testing metric are you asserting a 1.3 point intergroup gap?
English

@FranzJoseph145 @johnthenoticer @grok But its simply not true SES has to be at some 1% extreme to radically alter IQ between people that share the same DNA profiles - siblings, parents, twins
English

@loaburime @johnthenoticer @grok Basically there's a general rule, whereby heritability doesn't change much in SES -- but at the very end of the distribution tail there is a difference, since its super extreme. Kind of like the speed of light being a little different at an extremity
English

Recent twin study published:
As usual, the results show that genes have a far greater impact on IQ than the childhood environment.
⇒ The IQs of twins raised in separate homes converged over time.
⇒ This convergence was unrelated to how much contact the twins had with each other, their age at adoption, or their age at separation.
⇒ “Virtual twins” (same-age non-twin siblings raised together in the same household) saw their IQs diverge over time.
All these findings are consistent with the Wilson effect: as people get older, genes increasingly dominate individual traits while environmental influences fade in importance.

English

@FranzJoseph145 @johnthenoticer @grok I dont think this is a general rule at all
What if I were to list studies of adopted kids having higher IQs than their siblings, parents, or twins?
I dont think youll change your mind as this is something you want to believe
English

@FranzJoseph145 @johnthenoticer @grok I dont believe this theory holds for IQ as these two things are radically different but Im not gonna agree with you
English

@loaburime @johnthenoticer @grok It is only at the extreme upper tail end of the velocity distribution (as v to c) that this rule suddenly activates, causing time to visibly slow down for the moving object.
English

@FranzJoseph145 @johnthenoticer @grok To be fair the Bates paper seems to confirm ur claim, but again env. variance in some 1st-world nations is lower. Weird enough Asbury study shows opposite - bad env. leads to better verbal ability. Not sure what to make of that as verbal is more narrow & env affects heritability
English

@loaburime @johnthenoticer @grok The papers are linked in the video.
Replication Attempts for Turkheimer's low SES heritability claim:
sci-hub.tw/10.1017/S00219…
sci-hub.tw/10.1016/j.inte…
sci-hub.tw/10.1016/j.inte…
apps.cla.umn.edu/directory/item…
they might fail since its an older video
English

@FranzJoseph145 @johnthenoticer @grok I tried to be fair and link the only two studies I saw cus I couldnt view the whole video.
Just wondering if i can get the same courtesy. Again, not a gotchya
English

@loaburime @johnthenoticer @grok Basically there is a failure to replicate the Scar-Rowe hypothesis, apart from super deprived statuses, meaning that in the grand scheme of things the cross-racial differences in heritability as a result of SES are minimal/0.
Gemini notes the harsh language/ad homs of the video
English

@FranzJoseph145 @johnthenoticer @grok I understand thats what the video says but Im personally interested in tracking down all five papers and asking chatgpt as the video is very biased naturally.
Not trying to fight, Im genuinely curious.
English

@FranzJoseph145 @johnthenoticer @grok Yes, this is part of it. Having similar cultures not affected by slavery, Jim Crow, a history of extreme poverty, illiteracy, not being able to go to school etc can have intergenerational effects which is why SES variance of vastly different groups is important
English

@FranzJoseph145 @johnthenoticer @grok Again, thank you. Was hoping for a link though...is that possible?
If you can list the 5 studies Id be happy to paste them in chatgpt for both of us. Same style, no leading questions for bias
English

@loaburime @johnthenoticer @grok 2/2
However, labeling Turkheimer’s view as completely "fringe" or a "bald-faced lie" overlooks the fact that the effect has been observed in specific US cohorts, likely due to the extreme variance in environment and deprivation found in certain American baseline
English

@FranzJoseph145 @johnthenoticer @grok Hmmm, so what i was hoping for was to ask gemini about the studies directly and not the transcript of your video and see its reasoning for all 5 papers.
I also wanted to track down the papers myself
English

@loaburime @johnthenoticer @grok 1/2 Therefore, the transcript is correct that the effect has failed to replicate globally and is inconsistent even within the US.
