>In the US, there is a large stubborn Black-White differential in intelligence. This differential, on the individual and population level, explains a large portion of the social outcome difference. Within populations, intelligence is highly heritable. As such, the behavioral genetic default is that this differential also has a high heritability. It could be otherwise, though. As such, facts on the ground were explored and environmental explanations were evaluated. The facts include: (1) the difference is a true difference in psychometric intelligence, (2) it largely represents a difference in the general factor, (3) it has shown great persistence, having decreased little in the last century, (4) there is currently regression with age, (5) there appears to be a robust biological component to the difference, (6) the difference shows a Spearman/Jensen Effect, (7) biometric analysis indicates that the gap has a sizable genetic component, (8) the difference is not caused by environmental influences unique to one or the other populations, (9) if environmental influences are causing the gap they act fairly uniformly across the population, (10) the difference is no smaller at the upper SES levels than the lower, (11) family influences can not explain the difference, statistically explaining a decreasing amount with age, (12) Mixed race individual perform intermediate to monoracial individuals and this phenomena has been noted for centuries, (13) the Difference correlates with physical indexes of Caucasian admixture in the Black population, and (14) environmental interventions appear to show little to no lasting effect. Causal biological explanations were then explored and found to be wanting, capable of explaining at most 1/15th of the gap.
