RT Journal Article SR Electronic T1 Heredity, Environment, and Educational Policy JF Harvard Educational Review JO herp FD Harvard Educational Press SP 338 OP 347 DO 10.17763/haer.39.2.nvr226676j010551 VO 39 IS 2 A1 Cronbach, Lee YR 1969 UL http://harvardeducationalreview.org/content/39/2/338.abstract AB Professor Cronbach accepts some but by no means all of Professor Jensen's empirical conclusions. In the following review he indicates some research that bears on their points of disagreement. Cronbach suggests that such distinctions as Jensen's dichotomy between "Level I" and "Level II" abilities over-simplify the many dimensions of individual differences, and he disagrees with the educational policy he feels is implied by Jensen's recommendations for education. Beyond this,Professor Cronbach poses a more basic question—"Intelligence for what?"—a question of the compatibility of current social aims of schooling with long range changes in our social and technological structure.
