Evidence shows that education and intelligence have a complex interaction, and this is demonstrated in a longitudinal study by Richards and Sacker. [9] They collected data from the British 1946 birth cohort and investigated how childhood intelligence was predictive of other outcomes later in life including educational attainment and mental ability at 53 years old (using the National Adult ...
For example, the negative intelligence–religiosity association was insignificant with samples using men, pre-college participants, and taking into account grade point average. When other variables like education and quality of human conditions were taken into account, positive relation between IQ and disbelief in God was reduced. [8]
IQ and educational attainment are strongly correlated (estimates range form .40 to over .60. [11]) There is controversy, however, as to whether education affects intelligence – it may be both a dependent and independent variable with regard to IQ. [4] A study by Ceci illustrates the numerous ways in which education can affect intelligence.
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 ...
In psychology, human intelligence is commonly assessed by IQ scores that are determined by IQ tests. In general, higher IQ scores are associated with better outcomes in life. [ 11 ] However, while IQ test scores show a high degree of inter-test reliability , and predict certain forms of achievement effectively, their construct validity as a ...
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
The average fertility in his study was correlated at −0.031 with IQ for white women and −0.086 for black women. Vining argued that this indicated a drop in the genotypic average IQ of 1.6 points per generation for the white population, and 2.4 points per generation for the black population. [11]
The association is attenuated, but not removed, when controlling for socio-economic variables, such as educational attainment or income. This suggests that IQ may be an independent risk factor for mortality. One study found that low verbal, visuospatial and arithmetic scores were particularly good predictors of coronary heart disease.
