Secular IQ increases by epigenesis? The hypothesis of cognitive genotype optimization.

Psychological reports - 1 Oct 2011

Greiffenstein Manfred F

Abstract excerpt

The short timescale of massive secular IQ gains ("Flynn Effect") is inconsistent with positive selection of a recent gene mutation, but other genetic mechanisms are possible. Principles of evolutionary psychology, combined with secular trends, suggest an epigenetic explanation: the Cognitive Genome Optimization Hypothesis. Per life-history theory, favorable secular trends may change the phenotypic expression of...
