Those who do better on childhood intelligence tests tend to have a lower drop out rate, and complete more years of school and are predictive of school success. [4] For instance, one of the largest ever studies found a correlation of 0.81 between the general intelligence or g-factor and GCSE results. [13]
Cultural deprivation is a theory in sociology where a person has inferior norms, values, skills and knowledge. The theory states that people of lower social classes experience cultural deprivation compared with those above and that this disadvantages them, as a result of which the gap between classes increases.
The Cattell–Horn–Carroll theory is an integration of two previously established theoretical models of intelligence: the theory of fluid and crystallized intelligence (Gf-Gc) (Cattell, 1941; Horn 1965), and Carroll's three-stratum theory (1993), a hierarchical, three-stratum model of intelligence. Due to substantial similarities between the ...
In general, intelligence is thought to be attributed to both genetic and environmental factors, but the extent to which each plays a key role is highly disputed.

Intelligence quotient (IQ) tests do correlate with one another and that the view that the general intelligence factor (g) is a statistical artifact is a minority one. IQ scores are fairly stable during development in the sense that while a child's reasoning ability increases, the child's relative ranking in comparison to that of other ...
Human Cognitive Abilities: A Survey of Factor-Analytic Studies is a 1993 book by psychologist John B. Carroll. It provides an overview of psychometric research using factor analysis to study human intelligence. It has proven highly influential in subsequent intelligence research; in 2009, Kevin McGrew described it as a "seminal treatise". The ...
