Genome-wide association studies establish that human intelligence is highly heritable and polygenic
A genome-wide analysis of unrelated adults with data on single nucleotide polymorphisms and detailed phenotypes on cognitive traits unequivocally confirms that a substantial proportion of individual differences in human intelligence is due to genetic variation, and is consistent with many genes of small effects underlying the additive genetic influences on intelligence.
The impact of childhood intelligence on later life: following up the Scottish mental surveys of 1932 and 1947.

This research, using the surveys' data, examined the stability of intelligence differences across the life span, the determinants of cognitive change from childhood to old age, and the impact of childhood intelligence on survival and health in old age.
The NART as an index of prior intellectual functioning: a retrospective validity study covering a 66-year interval
The pattern of results provides strong support for the claim that the NART primarily indexes prior (rather than current) intellectual ability.
The Lothian Birth Cohort 1936: a study to examine influences on cognitive ageing from age 11 to age 70 and beyond
The principal strength of this cohort is the rarely captured phenotype of lifetime cognitive change, which is important in alerting other researchers to the data available in the cohort.

Longitudinal cohort study of childhood IQ and survival up to age 76
IQ at age 11 years was significantly associated with survival up to 76 years in an Aberdeen cohort and the association was unaffected by adjustment for overcrowding Men with high IQ were more likely to die in active service in the second world war.
The Stability of Individual Differences in Mental Ability from Childhood to Old Age: Follow-up of the 1932 Scottish Mental Survey
Genetic contributions to stability and change in intelligence from childhood to old age
An estimate of the genetic and environmental contributions to stability and change in intelligence across most of the human lifetime is provided using genome-wide single nucleotide polymorphism (SNP) data from 1,940 unrelated individuals whose intelligence was measured in childhood and in old age.
The functional COMT polymorphism, Val158Met, is associated with logical memory and the personality trait intellect/imagination in a cohort of healthy 79 year olds
