Herrnstein and Murray argue that intelligence is a better predictor of individuals' outcomes than parental socioeconomic status. This argument is based on analyses where individuals' IQ scores are shown to better predict their outcomes as adults than the socioeconomic status of their parents.

The performance of the African children will exceed that of the American children when the objects are rocks but not when they are Western household objects.
In other words, Ashley is interested in: the capacity to understand the world, think rationally, and use resources effectively. how behavior changes as a result of experience. the factors directing behavior toward a goal.
Even if a test is unreliable, it cannot be valid. Test validity and reliability are prerequisites for accurate assessment of intelligence. Test reliability and validity are highly desirable for an accurate assessment of intelligence. Knowing that a test is reliable guarantees that it is also valid.

Early theorists such as Spearman argued that g represented general intelligence. According to these theorist, individuals high in g:
Ashley, a psychology major, remarks that she has become interested in the study of intelligence. In other words, Ashely is interested in:
Using data from the General Social Survey, they tested each of these hypotheses using a short verbal ability test which was administered to about 12,500 American adults between 1974 and 1994; the results provided no support for any of the trend hypotheses advanced by Herrnstein and Murray. One chart in The Bell Curve purports to show that people with IQs above 120 have become "rapidly more concentrated" in high-IQ occupations since 1940. But Robert Hauser and his colleague Min-Hsiung Huang retested the data and came up with estimates that fell "well below those of Herrnstein and Murray." They add that the data, properly used, "do not tell us anything except that selected, highly educated occupation groups have grown rapidly since 1940."
Criticism by Stephen Jay Gould. Stephen Jay Gould wrote that the "entire argument" of the authors of The Bell Curve rests on four unsupported, and mostly false, assumptions about intelligence: Intelligence must be reducible to a single number. Intelligence must be capable of rank ordering people in a linear order.
Only non-Hispanic whites are included in the analyses so as to demonstrate that the relationships between cognitive ability and social behavior are not driven by race or ethnicity. Herrnstein and Murray argue that intelligence is a better predictor of individuals' outcomes than parental socioeconomic status.
The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by psychologist Richard J. Herrnstein and political scientist Charles Murray, in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance, birth out of wedlock, and involvement in crime than are an individual's parental socioeconomic status. They also argue that those with high intelligence, the "cognitive elite", are becoming separated from those of average and below-average intelligence, and that this separation is a source of social division within the United States.
The introduction states six of the authors' assumptions, which they claim to be "beyond significant technical dispute":
Evolutionary biologist Joseph L. Graves described The Bell Curve as an example of racist science, containing all the types of errors in the application of scientific method that have characterized the history of scientific racism :
The Bell Curve received a great deal of media attention. The book was not distributed in advance to the media, except for a few select reviewers picked by Murray and the publisher, which delayed more detailed critiques for months and years after the book's release.
In terms of policy recommendations, Herrnstein and Murray oppose Affirmative Action and other compensatory programs on the grounds that they either have not worked, or have actually worsened the situation for minorities. The authors favor a society in which everyone has a valued place commensurate with their abilities.

The situation seems to be worsening, and thus the gap between the cognitive elite and the underclass growing, because of the tendency of poorer individuals of lower intelligence to out reproduce the more wealthy and more highly intelligent.
The Bell Curve. Herrnstein and Murray’s The Bell Curve (1994) is one of the most controversial and widely debated works of social science in the second half of the twentieth century.
The cognitive elite has become increasingly separated from the rest of society by their attendance at elite universities, where they meet other highly intelligent individuals and intermarry, thus producing highly intelligent children who are likely to remain members of the elite intergenerationally.
