[華生突破盲腸] 黑人智商比白人低，竟然有基因證據？

答案係無（至少暫時 ）
同埋「白人」「黑人」呢啲種族劃分本身就有問題
更加唔好講 雖然智商部分受基因影響
但係啲咁複雜嘅現象
肯定唔係一兩個基因控制，而係一大堆
你覺得真係會同膚色/ancestry掛勾

原po #206 : https://lihkg.com/thread/981201/page/1

成班on9連登仔連genetics都無學過就學人吠
有邊個quote得出論文證明黑人基因會令佢地智商比較低

班on9仔係咪連黑人嘅genetic diversity最高，根本唔可以分做同一個種族呢樣基本常識都唔知

見到ching出現就知有戲睇

不了 廢事浪費口水
in case 有人見到呢個comment
我會留底一啲同廣義race and genetics相關嘅資料
基本上全部免費，你可以驗證
如果有讀bioinformatics嘅巴打請指教

不過留名等睇連登仔話全部學術機構都畀左膠入侵
連登仔勁過所有專業訓練嘅geneticist, psychologist
----------------------------------------------------------

呢兩段片主要係講究竟有無genetic證據支持傳統嘅種族劃分
tl;dw-->答案係無

----------------------------------------------------------
美國人類基因學會 （The American Society of Human Genetics）就係見到班白人至上主義者攞genetics打飛機
所以特等出咗篇立場書反駁
https://linkinghub.elsevier.com/retrieve/pii/S000292971830363X
// Genetics demonstrates that humans cannot be divided into biologically distinct subcategories.//
// Most human genetic variation is distributed as a gradient, so distinct boundaries between population groups cannot be accurately assigned.//
// It follows that there can be no genetics-based support for claiming one group as superior to another.//

而且有基本知識嘅人就知道
非洲人嘅基因多樣性（對比歐洲人、亞洲人）係最大
https://www.nature.com/articles/ng1435
// Second, the African populations are more diverse, a pattern consistent with many studies that have compared π in various human populations.//


將非洲人按膚色編埋一齊叫「黑人」
根本on9

---------------------------------------------------------------------
以上係反駁「種族」呢個概念響基因學嘅疑似基礎

至於「白人」「黑人」嘅智商差異
可以參考美國心理學協會(APA)響2012年出嘅評論
“Intelligence: New findings and theoretical developments.”
http://psycnet.apa.org/record/2011-30298-001
呢篇文非常值得睇
連登仔成日loop嘅point，咩「男女先天能力差異好大會影響學習進度」啊、「亞洲/猶太人天生好聰明」之類
都有address到
// This is an adoption study by Moore (1986). She examined the IQs of Black and mixed- race children averaging 81⁄2 years of age who were adopted by middle-class families who were either Black or White. The children who were of half-European origin had virtually the same average IQ as the children who were of exclusively Black origin. Hence European genes were of no advantage to this group of “Blacks.” Children (both Black and mixed-race) adopted by White families had IQs 13 points higher on average than those adopted by Black families, indicating that there were marked differences in the environments of Black and White families relevant to socialization for IQ;//
[...]
// Thus, the weight of the evidence suggests that stereotype threat probably accounts for some of the Black–White difference on intelligence-related tests under some circumstances. At the least, these
effects should give one considerable pause when interpreting group differences in intelligence test scores and academic achievement potential.//
------------------------------------------------------
所以 一句總結：
James Watson好勁，發現DNA；佢係相干嘅權威，無錯...
So what?
佢發表意見時有無cite peer-review source啊？
係咪連批判思考都唔知？

如果萊特兄弟話黃種人唔適合搭飛機
咁你係咪真係唔搭啊？

bookmarked
慢慢睇

利申 : racist as fuck

唔夠 juicy
上連登冇人理

班傻佬都係繼續屌你左膠

push
好彩平時有儲論文嘅習慣
寫文就方便得多

你確定？
Rushton, J. P., & Jensen, A. R. (2003). African–White IQ differences from Zimbabwe on the Wechsler Intelligence Scale for Children-Revised are mainly on the g factor. Personality and Individual Differences, 34(1), 177-183.



"As the essence of Spearman’s hypothesis is that the Black–White difference is primarily a dif- ference in g rather than in any other factors independent of g, a more direct method for testing it wasmade."

我知一定會有人用非洲國家環境差「證明」「黑人」基因差
按照同樣邏輯
香港政治環境差
--(完全係人種問題)-->
香港人 人種差
--(群體特徵等如所有個體特徵)-->
連登仔 人種差
--(「人種問題」 = 基因問題)-->
連登仔基因差

所以連登仔唔好響時事台嘈啦
香港之所以無民主+淪陷
全部都係你地先天嘅問題
無辦法改㗎啦，係咪？

估到會有人用Rushton同Jensen呢兩位人兄嘅著作出來講
第一
我揀嘅係2012年嘅review，你用嘅係2003年嘅論文

而且Rushton同Jensen呢兩位人兄嘅研究經費來源耐人尋味
Pioneer Fund
https://www.splcenter.org/fighting-hate/extremist-files/group/pioneer-fund

可能SPLC係垃圾左膠組織
咁直接睇內容
我個post講緊嘅係有無證據證明「黑人」同「白人」呢兩個群體嘅智力差異係同基因有關
而你篇文講緊嘅係「黑人」同「白人」呢兩個群體嘅智力有差異

所以你要質疑我嘅論點
麻煩搵一篇systemic review證明「黑人」同「白人」呢兩個群體嘅智力差異主要原因係基因

hi 認得巴打
上次性別認同單嘢真係打搞曬

樓主左膠

so9sad
明明我係本土派 唔信可以起我底

你開頭講"同埋「白人」「黑人」呢啲種族劃分本身就有問題"
點解引用以下一段開口埋口就black and white既文字
// This is an adoption study by Moore (1986). She examined the IQs of Black and mixed- race children averaging 81⁄2 years of age who were adopted by middle-class families who were either Black or White. The children who were of half-European origin had virtually the same average IQ as the children who were of exclusively Black origin. Hence European genes were of no advantage to this group of “Blacks.” Children (both Black and mixed-race) adopted by White families had IQs 13 points higher on average than those adopted by Black families, indicating that there were marked differences in the environments of Black and White families relevant to socialization for IQ;//
點解係 IQs of Black and mixed- race children 而唔係 Black and White children or Black and Asian children
你有冇方法排除到mixed-race children 黑人定白人父母果方面既基因對智商影響大啲
同埋IQ test 係咩類型,Culture Fair既test定有vocab既test
如果有verbal test有冇make sure 到language fluency 接近？

左膠逼害諾貝爾獎得主

btw呢個係右翼圈子咁流行嘅論述係邊度嚟

就當上面個個research係biased同未factor in cultural and educational influences

Naglieri, J. A., & Ronning, M. E. (2000). Comparison of White, African American, Hispanic, and Asian children on the Naglieri Nonverbal Ability Test. Psychological Assessment, 12(3), 328.




係同樣既educational background (US),asian generally shows higher scores in Maths, while White generally shows higher scores in Reading.而African American shows lower scores in ALL subjects that white.

雖然佢無比較唔同Economic status 既chart
但係佢個distribution 都算平均我就當佢合理

Controlled variables: Economic status, culture, education system
咁個variables 咪係 Genetic 囉

強貼留名

Child登仔唔睇journal無入嚟吠，終於有似樣討論

我話「白人」「黑人」呢啲種族劃分字眼本身就有問題，係因為佢地基因學上無根據，所以嘗試將「白人」「黑人」呢啲種族概念同基因扯埋一齊，就一定有問題

至於篇研究講嘅white black
一般係指種族上嘅自我/社會認同
文中都有強調係"socially classified black"
咁真係要研究，就算生物學上缺乏依據
但係社會上有明顯意義啊（stereotypes， 成長環境etc.）

至於個test
// The first phase of this investigation examined the response styles to the cognitive demands of the Wechsler Intelligence Scale for Children
(WISC)//
根據樓下巴打篇論文
// For example, the differencebetween White and African American children on the NNAT (an effect size of .25 or about 3.8 standard scores) is considerably less than the difference of 11 points on the Wechsler Intelligence Scale for Children (3rd ed.; Wechsler, 1991) reported by Prifitera and Saklofske (1998) for matched samples of White (n = 252) and African American (n = 252) children. //

Wechsler 個test 確實有verbal嘅成份
而且係對「黑人」兒童不利

Moore之所以要選擇mixed-race children
係要釐清之前Scarr and Weinberg (1976)留低嘅問題
即係點解1976年實驗 時mixed-race children分數較高
當年推測係因為嗰班mixed race兒童年齡較大 所以有bias
今次再做多次，控制相若年齡，果然分數即刻無signifcant difference

// 你有冇方法排除到mixed-race children 黑人定白人父母果方面既基因對智商影響大啲//
第一，根本依家都唔清楚有邊啲基因同正常範圍智力差異相關
當年點樣觀察研究？
更唔好講扯埋種族入來
「黑人」「白人」呢啲概念根本就缺乏基因基礎
膚色、面容輪廓呢啲特徵全部都係無數基因影響
你點樣響基因層面定義種族？
更加難泛泛而談「黑人」「白人」基因
