Abstract
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.
