We’ve learnt that the correlation between your daycare children’s genes and his behavior will grow increasingly weaker over time, as he approaches adulthood. But what about IQ and personality, two of the hottest topic in the nature vs nurture debate.
Studies seem to suggest a strong correlation between your daycare child’s environment and his mental development but the correlation disappears by adolescence. It seems that gene is more important than environment when explaining IQ in the general adult population.
The study of genes on personality also seem to point in the same direction. It suggest that genes do contribute significantly to a person’s personality as he progresses towards adulthood.
The question which one might ask is does genes determine who we are? If so, where does free will come in? Can we choose to be smarter by learning more or less temperamental by learning to control our tempers?
