RACE AND IQ: MIXED POPULATIONS PART 2

by Ryan Faulk

This article should be treated as a continuation of this article.  

In the previous article we looked at IQ studies of populations and samples of mixed-race people compared to monoracial subjects within a similar environment. Degrees of similarity of environment vary. For example, comparing identified racial groups in Brazil, or comparing identified racial groups within an adoption study.

In this article, we’re going to look at finer gradients of admixture and how that impacts on IQ and other standardized test scores.

RACE AND IQ: MIXED POPULATIONS

by Ryan Faulk

One argument for hereditarianism is that, around the world, mixed-race populations have IQs, or other standardized test scores, that are intermediate between the two races they are a mixture of.

Of course it’s messy, and we’re relying on subjective classification, but subjective classification is usually the same as best-fit genetic cluster anyway, and of course some populations of blacks could be genetically more intelligent than other populations, just as some populations of whites can be more intelligent than other populations of whites, and even some populations of blacks can be more intelligent than some populations of whites.

RACE AND STRESS

by Ryan Faulk

One of the non-genetic arguments used to explain racial IQ gaps is evnironmental stress. The idea being that blacks and Hispanics are more stressed than whites, and this releases stress hormones, which depresses IQ scores.
