Meanwhile, down in New York, Jensen Jensen's family is entirely different. Living in a sprawling apartment on Riverside Drive, Jensen maintains a group marriage menage. His marriage partners are Carlotta, Emery, Marian, and Clancy. Most often Jensen is paired off with Carlotta, and Emery with Marian. At odd times, when he is lonely, both Carlotta and Marian will pair off with Clancy. They have all studied the howling monkey society and they like what they have learned...
...author uses his theories to attack compensatory education programs, such as Operation Head Start, which assume that the withered young intellect will bloom if it is properly watered. Jensen contends that if substantial IQ improvement is the goal, all such programs will fail. He proposes instead that the schools broaden their approach to accommodate all levels of intelligence. Jensen writes: "Too often, if a child does not learn the school subject matter when taught in a way that depends largely on being average or above average, he does not learn...
...Jensen's more thoughtful critics concede some validity to this point. "Our educational systems," writes Geneticist Lederberg, "often neglect a child's strongest capabilities, and hold him back while focusing on his weaknesses." J. McVicker Hunt, a psychologist at the University of Illinois, agrees with Jensen that the child's first exposure to formal education is confining when it should be expanding. Says Hunt: "I am among those few who are inclined to believe that mankind has not yet developed and deployed a form of early childhood education (from birth to age five) which permits...
Mischievous Tests. But behavioral scientists are less willing to define with Jensen's confidence the comparative roles of heredity and environment in human intelligence. "I agree that it is foolish to deny the possibility of significant genetic differences between races," writes James F. Crow, a population geneticist at the University of Wisconsin, in a response to the Jensen article commissioned by Harvard's Review. "But this is not to say that the magnitude and direction of genetic racial differences are predictable." In American society, he adds, the environmental difference between being black and being white could of itself...
This possibility appears to gain support from a well-known study by Geneticists Irving I. Gottesman and James Shields, which was not cited by Jensen, of 38 pairs of identical white twins. Separated in infancy, these twins were reared in different environments. Gottesman and Shields found that, since the twins were presumed to be genetic equals, the environmental factor alone must have accounted for a spread of 14 IQ points-almost the same gap that separates black and white...
