Cognitive Abilities and the Growth of High-IQ Occupations Social Science Research 30,4 (December 2001): 529-551, Also: http://www.sciencedirect.com/science/article/pii/S0049089X01907100 Cohort(s): NLSY79 Publisher: Academic Press, Inc. Keyword(s): Cognitive Ability; General Social Survey (GSS); I.Q.; Occupational Status; Occupations Is there increasing cognitive partitioning by occupation over time? Herrnstein and Murray's The Bell Curve strongly suggests such a trend. Herrnstein and Murray specify 12 occupations as "high-IQ professions." They argue that as jobs in these occupations increase over time, more people with high IQs are drawn to these occupations. Thus, there is a growing concentration of the cognitive elite in high-IQ occupations and increasing cognitive partitioning by occupation. However, I find Herrnstein and Murray's analysis problematic due to lack of evidence and misinterpretation of data. Using data from the National Longitudinal Survey of Youth and the Wisconsin Longitudinal Survey, I rank occupations by incumbents' mean IQ and demonstrate that Herrnstein and Murray overestimate the rankings of some high-IQ occupations, the mean IQ level of persons in high-IQ occupations, and the percentage of high-IQ persons engaged in high-IQ occupations. In addition, using data from the General Social Survey, 1974-1998, I find no evidence that cognitive partitioning by occupation has increased over time. Copyright 2001 Academic Press. |

Occupational Standing and Occupational Differentials in Cognitive Ability Presented: Atlanta, GA, Population Association of America Annual Meetings, May 2002 Cohort(s): NLSY79 Publisher: Population Association of America Keyword(s): Cognitive Ability; I.Q.; Occupational Prestige; Occupational Status; Occupations; Wisconsin Longitudinal Study/H.S. Panel Study (WLS) Permission to reprint the abstract has not been received from the publisher. Some psychologists suggest that occupational differentials in social standing primarily reflect occupational differentials in intellectual demand. Using data from the National Longitudinal Survey of Youth 1979 Cohort and the Wisconsin Longitudinal Study, I examine (1) the rankings of occupations by mean IQ, (2) the correlation between ratings of occupational standing and occupations' average levels of measured cognitive ability, (3) the percentage of variance in IQ within occupations, and (4) whether or not the intra-occupational standard deviation of IQ decreases as the level of occupational standing increases. While occupations differ in incumbents' mean IQs, the variance of incumbents' IQs in an occupation is not much less than the variance of IQ in the general population. Moreover, the intra-occupational variance in IQ does not become smaller as the level of occupational standing increases. Therefore, the argument raised by some psychologists regarding the importance of cognitive ability in shaping occupational stratification is overstated. |
