U.S. psychiatric geneticists say they have confirmed an association between genetics and intelligence.

Washington University School of Medicine researchers in St. Louis gathered the most extensive evidence to date showing a gene that activates signaling pathways in the brain influences one kind of intelligence.

They report confirming a link between the gene CHRM2 and performance IQ, which involves a person’s ability to organize things logically.
