“…This is evolutionarily novel; thus, I would predict people with greater general intelligence to do it more effectively than those with less general intelligence. As Table 1 and numerous other studies show (Fryer, 1922;Harrell & Harrell, 1945;Jencks, 1972, pp. 220 -221;Jensen, 1980, pp.…”

General intelligence (g) poses a problem for evolutionary psychology's modular view of the human brain. The author advances a new evolutionary psychological theory of the evolution of general intelligence and argues that general intelligence evolved as a domain-specific adaptation for the originally limited sphere of evolutionary novelty in the ancestral environment. It has accidentally become universally important merely because we now live in an evolutionarily novel world. The available data seem to support the author's contention that intelligent people can solve problems better than less intelligent people only if the problems are evolutionarily novel, and they have no advantage in solving evolutionarily familiar problems. This perspective can also solve some empirical anomalies, such as the "central theoretical problem of human sociobiology" (D. R. Vining, 1986, p. 167) and the geographic distribution of general intelligence throughout the world.The g factor is actually a biologically based variable, which, like other biological functions in the human species, is necessarily a product of the evolutionary process. (Jensen, 1998, p. xii) I thank Garth J. O. Fletcher for disagreeing with me, thereby motivating me to write this article, and

“…I have computed the correlation between the occupation-specific mean and standard deviation, which is –.32—modest, but consistent with Jensen’s expectations. Rather, Jensen here relies mainly on a well-known set of data from World War II, giving scores of 18,782 White enlisted men in the Army Air Force on the Army General Classification Test (AGCT) along with previous civilian occupation (Harrell & Harrell, 1945). He describes the inverse relationship between the occupational test score and its standard deviation only with a series of anecdotes, but the correlation is remarkably high.…”

“…Moreover, civilians who scored exceptionally well were often placed in the officer ranks; that is, high scorers did not tend to show up among enlisted men. According to Harrell and Harrell (1945), “It is possible that averages among the professional occupations are too low since conceivably many of the best men in the profession would have been officer material” (pp. 229–230).…”

Causes and Consequences of Cognitive Functioning Across the Life Course

Research on variation in cognitive abilities has focused largely on their genetic or experiential sources and on their economic consequences. This article takes a broader look at the consequences of cognitive ability—IQ—across the life course. Contrary to received wisdom, the effects of IQ on economic success are almost entirely mediated by educational attainment. Among persons with equal levels of schooling, IQ has little influence on job performance, occupational standing, earnings, or wealth. But there are other, sometimes surprising consequences of IQ throughout adult life. The long-term correlates of adolescent cognition include drinking behavior, survey participation, Internet use, and the timing of menopause. These are surveyed primarily using findings from the Wisconsin Longitudinal Study.

“…There is a significant positive correlation between the mean IQ and the occupational prestige among both the draftees of World War I (Fryer, 1922) and those of World War II (Harrell & Harrell, 1945). The 1970 data from the U.S. Department of Labor show the following mean IQs for selected occupations: engineer (130), accountant (118), teacher (114), bookkeeper (110), photographer (108), stenographer (106), machinist (104), carpenter (99), laborer (92), and stock clerk (84).…”
