Reaction range: the reaction range in psychology refers to the concept that genetic potential limits an individual's range of possible developmental outcomes, but environmental factors determine where within this range the individual will fall. It is often used in the context of intelligence. See also Intelligence, Psychological development, Performance, Developmental psychology, Environment, Heritability. _____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

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. 1.
