But weak evidences for this view of things. The importance of g : high correlation of g amount several event. Explanation for this variability: trait variability genetics variability (nature) gxe interaction. Environmental variability (nurture: ex for 100% genetic: eyes color, disease , ex for 100% environmental: mother tongue, religious believes. Gene-environment interactions rats selectively bread to be bright or dull. Those who made the less error where grouped together, and these who made the more errors where grouped together. Raised the rat in restricted environment: smaller cage and alone, enriched: toys, very big cage in the restricted environment performed as bad as the dulls one.
