Arthur R. Jensen on Heritability - Dictionary of Arguments

Slater I 121
Heritability/Jensen: (Jensen 1969)(1)
(1) Genetic and environmental influences should not be considered independent of each other as they may be correlated and/or interact;
(2) heritability is a population statistic that does not apply to individuals;
(3) heritability can vary substantially from one environment to another;
(4) the level of heritability in one group does not mean that its level will be similar in other groups; (5) heritability in one group cannot be used to attribute mean differences between that group and another group to genetic differences between them;
(6) there were (and still are) many reasons to believe that environmental differences between middle- and upper-class European-Americans and disadvantaged African-Americans were (and still are) large,
(7) high heritability does not mean that a trait is immutable.
