Jensen presents a compelling case for the reality of g. This represents a major scientific achievement. However, I consider that there are two serious mistakes in his choice of scientific strategy. The first is to adopt an operational stance - that is, to drop all reference to the word 'intelligence' and define our object of scientific interest as the g-factor. This is a mistake because the operational stance does not work in science and in this particular case it strips the g factor of all of its psychological significance. The second mistake is in his pursuit of the g-nexus, where biological and psychological variables are related to social outcomes via g. Without a serious theory of mental structure, this attempt rings hollow. Indeed such a strategy impedes the more crucial scientific step of developing a theory of intelligence which, in the final analysis, is a theory of mental structure.
