> But bring up intelligence along with genetic factors and everyone recoils and tenses up. I don't think this is true; general intelligence is considered to be highly heritable (40-80% according to Wikipedia). If you start suggesting that g is correlated to race then you'll get a lot of push-back, but as far as heritability not really. To the degree that intelligence is affected by the environment, we should encourage things that help. Not starving kids and preventing them from ingesting lead both probably have a higher effect than reading, but I would not be surprised if reading doesn't at least cause some development to occur earlier (whether or not there are measurable effects that last into adulthood).
