But then the mutliple intelligences are more specific. Fluid intelleigence decreases with age, crystallized intelligence increases with age. Heritability of iq after late adolescence is about . 75. For children shared environment has an effect (> 20%). For most children (90% of the population), breast feeding was a predictor of higher iq (~ 7 points). For these children, breast feeding was also a predictor of mothers" iq (~ 8 points). After controlling for the effect of mothers" iq on children"s iq, the effect of breastfeeding is smaller (~ New formulas include fatty acids that may simulate the effect of breast milk. Both genes and environment matter. genetic effects are stable (unless biological changes occur due to brain damage or aging). You have to exercise your brain to maintain your iq. People are not very good at assessing their own intelligence.
