1. All studies and data show genes determine intelligence and there are racial differences. IQ tests, twin studies, transracial adoption, cranial volume, brain morphology, GWAS, racial admixture. Dog breeds, different species, human retards all show intelligence is genetic. Traits other than intelligence like skin color, athleticism are also genetic and differ racially.
2. Consistent with all known biology, theory of evolution, human migration out of Africa, miscegenation rates. Founder, bottleneck effects, archaic admixture and isolation theoretically produce races/subspecies. PCA, K clustering, Fst for human genome all reproduce the classic race groups (subsaharan, caucasian, east asian, amerindian, australoid). Genes are expressed in brain tissue, brain function affects evolutionary fitness.
3. Environment is proven irrelevant. Schools don't make all kids have the same intelligence, kids start out smart or stupid and stay that way, skip or get held back grades. Not only rich/healthy kids at good schools are smart, not only poor/sick kids at bad schools are stupid. East Asians are smart (and law abiding etc) everywhere they are in the world whatever the local racism level, Africans are stupid, criminal etc everywhere. In the US black kids are born smaller but grow faster than white, they aren't malnourished. Genes determine environment.
4. Environmentalism depends on fallacies (Lewontin), fabrication (Gould), deplatforming (Watson), denial. Despite ease of race/environment controlled IQ tests they can't produce data showing no race differences.
Against:
Flynn effect. Only solid point supporting environmental effects, but doesn't show intelligence isn't genetic or racial. IQs rose from 1900-1980 presumably because of improved nutrition and health, but height increased the same way and height is mostly genetic with racial differences, and health/nutrition doesn't explain why US blacks can dominate pro sports but still underperform academically.
