Objective: Socioeconomic factors have been suggested to influence the effect of education-
and intelligence-associated genetic variants. However, results from previous studies on the …

Causes of the well-documented association between low levels of cognitive functioning and
many adverse neuropsychiatric outcomes, poorer physical health and earlier death remain …

Education, socioeconomic status, and intelligence are commonly used as predictors of
health outcomes, social environment, and mortality. Education and socioeconomic status …

People's differences in cognitive functions are partly heritable and are associated with
important life outcomes. Previous genome-wide association (GWA) studies of cognitive …

Individuals with lower socio-economic status (SES) are at increased risk of physical and
mental illnesses and tend to die at an earlier age [1–3]. Explanations for the association …

Intelligence, as measured by standardised tests of cognitive function, such as IQ-type tests,
is predictive of psychiatric diagnosis and psychological wellbeing. Using genome-wide …

General intelligence is an important human quantitative trait that accounts for much of the
variation in diverse cognitive abilities. Individual differences in intelligence are strongly …

Pedigree-based analyses of intelligence have reported that genetic differences account for
50–80% of the phenotypic variation. For personality traits these effects are smaller, with 34 …

Cognitive deficits and reduced educational achievement are common in psychiatric illness;
understanding the genetic basis of cognitive and educational deficits may be informative …

OBJECTIVE: The purpose of the present study was to identify common genetic variants that
are associated with human intelligence or general cognitive ability. METHOD: We performed …
