Intelligence, brains and genetics


There is never a perfect starting point when dealing with a complex subject, but this review in Nature Reviews Neuroscience March 2010 “The neuroscience of human intelligence differences” by Ian J. Deary, Lars Penke and Wendy Johnson fills an important gap. Thanks to Stuart Ritchie for suggesting it as a point of origin.

It has good explanatory sections, and serves as a helpful introduction to the power of intelligence, and to the current search for a better understanding of the neural and genetic basis of the general ability we summarise as g.

The authors would be the first to point out that much has been added to our understanding of these issues in the subsequent three years, but that is always the trouble with starting points: where to start?
