Arthur R. Jensen on Reaction Range - Dictionary of Arguments
Slater I 124
Reaction range/genetic theories/psychology/Jensen: the genetic concept of “reaction range,” [indicates] the observation that the same genotype can give rise to rather different observable traits in different environments.
Jensen (1969(1) discussed this problem on pages 63-64. Another problem is, that different genotypes may show different reaction ranges: some may be more buffered than others from environmental circumstances.
[Jensen] noted that this implies that heritability estimates may vary for subgroups within population groups, specifically pointing out that no estimates of the heritability of intelligence were available to African-American groups, and that samples that included European-Americans of the same lower SES (socioeconomic status) level as many African-Americans were not sufficiently relevant, as the SES measure might not reflect racial differences in the environmental conditions that actually impact development of intelligence and/or academic performance. >Intelligence tests/Jensen, >Heritability/Jensen.
