Racial equality in intelligence: Predictions from a theory of intelligence as processing

Reducing Black–White Racial Differences on Intelligence Tests Used in Hiring for Public Safety Jobs

This paper explores whether a diversity and inclusion strategy focused on using modern intelligence tests can assist public safety organizations in hiring a talented diverse workforce. Doing so may offer strategies for mitigating the issues of systematic racism with which these occupations have historically struggled. Past meta-analytic research shows that traditional forms of intelligence tests, which are often used in this sector, have not consistently demonstrated predictive validity but have negatively impacted Black candidates. As an alternative, we examine a modern intelligence test that consists of novel unfamiliar cognitive problems that test takers must solve without relying on their prior experience. Across six studies of varying public safety jobs (e.g., police, firefighter) in different organizations, we found a pattern of results that supports the criterion-related validity of the modern intelligence test. In addition to consistently predicting job performance and training success, the modern intelligence test also substantially mitigated the observed Black–White group differences. The implications of these findings are discussed in terms of how to alter the legacy of I/O psychology and human resource fields when it comes to our impact on facilitating employment opportunities for Black citizens, particularly in public safety positions.

Adaptive Behavior as an Alternative Outcome to Intelligence Quotient in Studies of Children at Risk: A Study of Preschool-Aged Children in Flint, MI, USA

Intelligence quotient (IQ) is commonly measured in child development studies, while adaptive behavior is less frequently considered. Given its associations with functional outcomes in children with neurodevelopmental disabilities, adaptive behavior may be a useful outcome in general population samples, as well. This study aimed to compare social and environmental correlates of adaptive behavior vs. IQ in a sample of preschoolers exposed to the Flint water crisis (N = 184). Mother-child dyads were recruited from the community and administered a comprehensive battery to obtain information about child neurodevelopmental functioning, including direct assessment of IQ via the Wechsler Preschool and Primary Scale of Intelligence and assessment of parent-reported adaptive functioning via the Vineland Adaptive Behavior Scales. Multiple social environmental factors were explored as potential correlates of child outcomes (i.e., IQ and adaptive behavior), and robust correlates were identified using a data-driven approach [i.e., least absolute shrinkage and selection operator (LASSO) regression]. We then examined associations between the LASSO-selected predictors and IQ and adaptive behavior while controlling for child age, child sex, and maternal age. Children in this sample showed relative strength in adaptive behaviors, with scores in the adequate range, while average IQs fell in the low-average range. Adaptive behavior was significantly associated with maternal nurturance practices, while IQ was associated with the maternal education level. Implications for the use of adaptive behavior as an outcome measure in studies of children at an increased risk for neurodevelopmental problems are discussed.

Intelligence 2.0: Reestablishing a Research Program on g in I–O Psychology

Intelligence (i.e., g, general mental ability) is an individual difference that is arguably more important than ever for success in the constantly changing, ever more complex world of business (Boal, 2004; Gatewood, Field, & Barrick, 2011). Although the field of industrial–organizational (I–O) psychology initially made substantial contributions to the study of intelligence and its use in applied settings (e.g., Hunter, 1980; Schmidt & Hunter, 1981), we have done relatively little in recent times about studying the nature of the intelligence construct and its measurement. Instead, we have focused predominately on using intelligence to predict performance outcomes and examine racial subgroup differences on intelligence test scores. Although the field of I–O psychology continues to approach intelligence at a surface level, other fields (e.g., clinical psychology, developmental and educational research, and neuropsychology) have continued to study this construct with greater depth and have consequently made more substantial progress in understanding this critical and complex construct. The purpose of this article is to note this lack of progress in I–O psychology and to challenge our field to mount new research initiatives on this critical construct.

Styles of Learning and Thinking Matter in Instruction and Assessment

There are two styles of learning and thinking: ability based and personality based. The former are assessed by maximum-performance tests, and the latter are assessed by typical-performance tests. We argue that both kinds of styles matter for instruction and assessment in school. In particular, shaping lessons based on an awareness that people learn and think in different ways can lead to improved instructional outcomes. We describe one ability-based theory and one personality-based theory and present supporting data from multiple studies relevant to each.
