Many workers assume that genetically determined differences in intellectual ability1–5 will be influenced little by changes in educational policy or other environmental interventions6,7. Others8,9, however, have suggested that increasing equality of educational opportunity will lead to an increase in the heritability of educational attainment. The resolution of this issue has been delayed until now because of the extremely large sample sizes which would be required10. Education data on twins… 
Equality in Educational Policy and the Heritability of Educational Attainment
The results support the role of educational policy in affecting the relative weight of genetic and environmental factors on educational attainment, such that increasing equality in educational opportunities increases heritability estimates by reducing variation of non-genetic familial origin.
Genetics of educational attainment in Australian twins: Sex differences and secular changes
Unlike previous studies in Scandinavian countries, results in Australia suggest that factors influencing educational success are comparable between women and men and for individuals born at different points during this century.
Is the Effect of Parental Education on Offspring Biased or Moderated by Genotype?
This work exploits the findings from a recent large genome-wide association study of educational attainment to construct a genetic score designed to predict educational attainment, and finds that this genetic score significantly predicts years of schooling in both between-family and within-family analyses.
Genetic and environmental variation in educational attainment: an individual-based analysis of 28 twin cohorts
Both genetic and environmental factors shared by co-twins have an important influence on individual differences in educational attainment, and the effect of genetic factors on educational attainment has decreased from the cohorts born before to those born after the 1950s.
Genes, Gender Inequality, and Educational Attainment
Women’s opportunities have been profoundly altered over the past century by reductions in the social and structural constraints that limit women’s educational attainment. Do social constraints
Genetics of Educational Attainment and the Persistence of Privilege at the Turn of the 21st Century
We use structural equations methodology with data on 1,576 pairs of variously related young adult siblings (MZ twins, DZ twins, full siblings, half siblings, cousins, and nonrelated siblings) to

The sizable contribution of genes to these socioeconomic outcomes suggests that standard sociological and economic theories on the socioeconomic career require substantial modification to accommodate the role of genetics.
Social and genetic associations with educational performance in a Scandinavian welfare state.
Recent research has suggested that across Western developed societies, the influence of genetics on educational outcomes is relatively constant. However, the degree to which family environment


Effects of inbreeding on cognitive performance
It is shown here that offspring of unrelated parents performed better than offspring of first-cousin marriages in intelligence and achievement tests administered at grades 4 and 6, and the inbreeding depression found in this study is consistent and cannot be explained by the effects of socioeconomic status.
Causal analysis of academic performance
It is stressed that a racial effect in a causal system may be environmental and that its etiology can be studied only by analysis of family resemblance in hybrid populations.
Analysis of behavioral traits in the presence of cultural transmission and assortative mating: Applications to IQ and SES
General linear models of familial resemblance are described which allow for polygenic inheritance, cultural transmission from parent to offspring, phenotypic assortative mating, common environment,
Predicting zygosity in Norwegian twin pairs born 1915–1960
The questionnaire data are sufficient to adequately score twin pairs for zygosity in the great majority of cases and could be predicted with satisfactory reliability also for twin pairs where only one of the twins had responded.
The power of the classical twin study
In the absence of genotype-environment interactions, distributional skewness and mean-variance regression in DZ twins are found to be more powerful tests of directional dominance than the standard model fitting procedure and these tests may be worthwhile in future studies.
Resolving the effects of phenotype and social background on mate selection
Power simulations show that it will be feasible to resolve the contributions of phenotype and social background to mate selection for variables such as IQ, education, and attitudes for which the marital correlation is moderately high.
XV.—The Correlation between Relatives on the Supposition of Mendelian Inheritance.
Several attempts have already been made to interpret the well-established results of biometry in accordance with the Mendelian scheme of inheritance. It is here attempted to ascertain the biometrical
Heredity-environment analyses of Jencks's IQ correlations
It is shown empirically that differences in selection of data and in computational procedures and logical inconsistencies in specifying equations are not responsible for the differences in results, rather, the differences trace to the underlying assumptions made by the various authors.
Model-fitting approaches to the analysis of human behaviour
Several statistical methods have been proposed for parameter estimation and hypothesis testing and the most suitable rely on the method of maximum likelihood for the estimation of variance and covariance components.
Insignificance of Evidence for Differences in Heritability of IQ between Races and Social Classes
Evidence previously analysed is insufficient to support the conclusions drawn, so no conclusions can be drawn.
