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: In this paper, the authors take a number of well known informal definitions of human intelligence and extract their essential features, which are then mathematically formalised to produce a general measure of intelligence for arbitrary machines, and show how this formal definition is related to the theory of universal optimal learning agents.
Abstract: A fundamental problem in artificial intelligence is that nobody really knows what intelligence is. The problem is especially acute when we need to consider artificial systems which are significantly different to humans. In this paper we approach this problem in the following way: We take a number of well known informal definitions of human intelligence that have been given by experts, and extract their essential features. These are then mathematically formalised to produce a general measure of intelligence for arbitrary machines. We believe that this equation formally captures the concept of machine intelligence in the broadest reasonable sense. We then show how this formal definition is related to the theory of universal optimal learning agents. Finally, we survey the many other tests and definitions of intelligence that have been proposed for machines.

TL;DR: This chapter reviews personnel selection research from 1995 through 1999, with three major themes revealed: better taxonomies produce better selection decisions, and the field of personality research is healthy, as new measurement methods, personality constructs, and compound constructs of well-known traits are being researched and applied to personnel selection.
Abstract: This chapter reviews personnel selection research from 1995 through 1999. Areas covered are job analysis; performance criteria; cognitive ability and personality predictors; interview, assessment center, and biodata assessment methods; measurement issues; meta-analysis and validity generalization; evaluation of selection systems in terms of differential prediction, adverse impact, utility, and applicant reactions; emerging topics on team selection and cross-cultural issues; and finally professional, legal, and ethical standards. Three major themes are revealed: (a) Better taxonomies produce better selection decisions; (b) The nature and analyses of work behavior are changing, influencing personnel selection practices; (c) The field of personality research is healthy, as new measurement methods, personality constructs, and compound constructs of well-known traits are being researched and applied to personnel selection.

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.
