[quote=Anonymous][quote=Anonymous]School achievement is mostly a genetic issue. Once we allow people to choose the embryo with the best genetic potential, or provide free sperm/eggs of good genetic potential, the percentage of kids with low iq and major behavior problems will go down a lot. [/quote]

It's not, though.  IQ is only 40% heritable.  That means the vast majority of our intelligence stems from our environment and epigenetic impacts on brain development.  Wealthier children with educated parents grow up in environments that promote intelligence.  Proper prenatal care, no drug exposure in utero, good postnatal nutrition, warm responsive caregivers, proper sleep routines, enriching environment with lots of verbal stimulation and low screen exposure.  The majority of brain development happens before kids ever enter a school building, and that includes preschool.

Too many children don't have access to the above because their parents did not plan their conception and/or don't have the material or emotional resources to create a brain-nurturing environment.[/quote]
