Yes. And Its worse for pure bred negros... far far worse. USA IQ tables in 2021 incorporate only 55% White people for the age 17 tables... If using 1985 tables, (far less hispanics) and using pure bred negroid scores, or even american blacks.... Blacks are practically RETARDED! look at bottom of this list of IQ from composited science paper research : https://iq-research.info/en/average-iq-by-country Sri Lanka - 79 IQ !!! Zambia - 79 Democratic Republic of the Congo - 78 Nepal - 78 Qatar - 78 Comoros - 77 South Africa - 77 Cape Verde - 76 Congo - 76 Mauritania - 76 Senegal - 76 Mali - 74 Namibia - 74 Ghana - 73 Tanzania - 72 Central African Republic - 71 Jamaica - 71 Saint Vincent and the Grenadines - 71 Sudan - 71 Antigua and Barbuda - 70 Benin - 70 Botswana - 70 Rwanda - 70 Togo - 70 Burundi - 69 Cote d'Ivoire - 69 Ethiopia - 69 Malawi - 69 Niger - 69 Angola - 68 Burkina Faso - 68 Chad - 68 Djibouti - 68 Somalia - 68 Swaziland - 68 Dominica - 67 Guinea - 67 Guinea-Bissau - 67 Haiti - 67 Lesotho - 67 Liberia - 67 Saint Kitts and Nevis - 67 Sao Tome and Principe - 67 The Gambia - 66 Cameroon - 64 Gabon - 64 Mozambique - 64 Saint Lucia - 62 Equatorial Guinea - 59 IQ !!! The smartest countries all have the least brown or black skins. Millions of IQ tests show that a generous "black" IQ of > 80 is for half-white or quarter-white american blacks , not pure bred actual african blacks. The darkest skin are BELOW IQ 80 and frequently retested by scientists out of shock at the values. The reason is genetic. Blacks lack countless important intelligence genes. The smartest countries all have the least brown or black skins. SKIN COLOR proven related to IQ: https://files.catbox.moe/eko2da.png **GENES 80% Predict your IQ!!!** ============= DNA is well proven to be source of 80% of IQ based on mammoth research studies. The two bombshell 80% DNA source of IQ studies ! : 2018 : 1,016 genes paper = *Genome-Wide Association Meta-Analysis In 269,867 Individuals Identifies New Genetic And Functional Links To Intelligence* Nature Genetics (2018) https://doi.org/10.1038/s41588-018-0152-6 Now 1,016 genes are proven correlated to IQ (many are brain , skull, or birth canal related, some might be merely (non-negroid) genes in general. 2018 : 538 genes UK Biobank DNA yields 538 genes that are linked to intellectual abilities - genetic effects on intelligence and personality https://www.news-medical.net/news/20180313/Large-number-of-genes-associated-with-intelligence-discovered.aspx https://doi.org/10.1038/s41380-017-0005-1 pop science description of the above : **538 genes that are thought to be linked to intelligence (by comparing 300,000 test subjects) :** https://archive.is/pJYfe (original deleted and censored, archive exists) **Table showing over 25 IQ related specific genes that MOSTLY are missing in africans**: https://files.catbox.moe/2pqwi6.png That is an abbreviated list that omits genes that all Blacks lack from Neanderthals for brain size, brain folding, and female birth canal shape.
