Study Finds A New Look at Genetic Factors in Intelligence Needed
A new study finds that most of the specific genes long thought to be linked to intelligence probably have no bearing on one’s IQ. Furthermore, researchers say that it may be some time before researchers can identify intelligence’s specific genetic roots.
In the study, Christopher Chabris of Union College and David Laibson, a Harvard economist, analyzed a dozen genes using large data sets that included both intelligence testing and genetic data. In nearly every case, the researchers found that intelligence could not be linked to the specific genes that were tested. The results are published online in Psychological Science.
