A recent article published in the New York Times ("If Intelligence is the Norm, Stupidity Gets More Interesting"), David Dobbs notes that when it comes to the search for specific genes that affect one's intelligence scientists have only been able to identify ... two:
One determines the risk of Alzheimer’s and affects I.Q. only late in life; the other seems to build a bigger brain, but on average it raises I.Q. by all of 1.29 points.
Instead, there are a whole confluence of genes that can account for the variation in intelligence, and given our limited understanding of how these genes work together it seems as though Baby Geniuses will continue to always be a decade away (to the disappointment of dozens). Yet, instead of focusing on the genes that produce intelligence perhaps we should search for the mutations that inhibit it. As Dr. Kevin Mitchell writes at his blog Wiring the Brain:
