Why g Matters: The Complexity of Everyday Life
- This article provides evidence that g has pervasive utility in work settings because it is essentially the ability to deal with cognitive complexity, in particular, with complex information processing.
- Few claims in the social sciences are backed by such massive evidence but remain so hotly contested in public discourse.
- Besides demonstrating that g is important in practical affairs, I seek to demonstrate why intelligence has such surprisingly pervasive importance in the lives of individuals.
- I then use both the employment and literacy data to sketch a portrait of life’s challenges and opportunities at different levels of intelligence.
WHAT DOES “IMPORTANT” MEAN?
- The nature of the job and its context seem to determine whether g has any direct effect on task proficiency, net of job knowlege.
- As is well known in psychometrics (see also Gordon, 1997), the fact that an individual passes or fails any single test item says little about that person’s general intelligence level.
INFLUENCE OF INTELLIGENCE ON OVERALL LIFE OUTCOMES
- The effects of intelligence-like other psychological traits-are probabilistic, not deterministic.
- White adults in this range marry, work, and have children (Hermstein & Murray, 1994), but, as Table 10 shows, they are nonetheless at great risk of living in poverty (30%), bearing children out of wedlock (32%), and becoming chronic welfare dependents (31%).
- At this IQ level, fewer than half the high school graduates and none of the dropouts meet the military’s minimum AFQT enlistment standards.
- Most occupations are within reach cognitively, because these individuals learn complex material fairly easily and independently.
- Such as divorce, illness, and occasional unemployment, they rarely become trapped in poverty or social pathology.
THE FUTURE
- Complexity enriches social and cultural life, but it also risks leaving some individuals behind.
- Society has become more complex-and g loaded-as the authors have entered the information age and postindustrial economy.
- Accordingly, organizations are “flatter” (have fewer hierarchical levels), and increasing numbers of jobs require high-level cognitive and interpersonal skills (Camevale, 1991; Cascio, 1995; Hunt, 1995; Secretary’s Commission on Achieving Necessary Skills, 1991).
- There is evidence that increasing proportions of individuals with below-average IQs are having trouble adapting to their increasingly complex modern life (Granat & Granat, 1978) and that social inequality along IQ lines is increasing (Herrnstein & Murray, 1994).
- As the military experience also illustrates, however, what is good pedagogy for the low-aptitude learner may be inappropriate for the high-aptitude person.

TL;DR: Cognitive enhancement is a prime example of a converging technology where individual disciplines merge and issues transcend particular local discourses.
Abstract: Cognitive enhancement, the amplification or extension of core capacities of the mind, has become a major topic in bioethics. But cognitive enhancement is a prime example of a converging technology where individual disciplines merge and issues transcend particular local discourses. This article reviews currently available methods of cognitive enhancement and their likely near-term prospects for convergence.

TL;DR: In this article, the authors describe a common structure and how it can be used in assessing person-job match in terms of general ability level and ability profile, and suggest ways of resolving various technical and professional questions, such as which cognitive abilities to assess, how to assess them, what the most useful aptitude-based occupational classification would be, and how to use cognitive assessments in a broader "reality-based exploration" process intended to expand people's career opportunities.
Abstract: Abilities are as important as interests in career choice and development. Reviving cognitive assessment in career counseling promises to help counselees better understand their career options and how to enhance their competitiveness for the ones they prefer. Nearly a century of research on human cognitive abilities and jobs' aptitude demands in the U.S. economy reveals that the two domains are structured in essentially the same way. The author describes that common structure and how it can be used in assessing person-job match in terms of general ability level and ability profile. She also suggests ways of resolving various technical and professional questions, such as which cognitive abilities to assess, how to assess them, what the most useful aptitude-based occupational classification would be, and how to use cognitive assessments in a broader “reality-based exploration” process intended to expand people's career opportunities.

TL;DR: In this article, the authors investigated the relation of the Big Five personality dimensions (extraversion, emotional stability, Agreeableness, Conscientiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skilled/semi-skilled).
Abstract: This study investigated the relation of the “Big Five” personality dimensions (Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skilled/semi-skilled). Results indicated that one dimension of personality, Conscientiousness, showed consistent relations with all job performance criteria for all occupational groups. For the remaining personality dimensions, the estimated true score correlations varied by occupational group and criterion type. Extraversion was a valid predictor for two occupations involving social interaction, managers and sales (across criterion types). Also, both Openness to Experience and Extraversion were valid predictors of the training proficiency criterion (across occupations). Other personality dimensions were also found to be valid predictors for some occupations and some criterion types, but the magnitude of the estimated true score correlations was small (ρ < .10). Overall, the results illustrate the benefits of using the 5-factor model of personality to accumulate and communicate empirical findings. The findings have numerous implications for research and practice in personnel psychology, especially in the subfields of personnel selection, training and development, and performance appraisal.
