New evidence that intelligence is largely inherited
Research by a team of scientists from UCLA shows that intelligence is largely inherited.
In a study published recently in the Journal of Neuroscience, UCLA neurology professor Paul Thompson and colleagues used a new type of brain-imaging scanner to show that intelligence is strongly influenced by the quality of the brain’s axons, or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain’s wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.
I.e., socio-economic status and other environmental factors play a far smaller role in intelligence than was previously thought.
Richard J. Herrnstein and Charles Murray would not be surprised by this discovery.
