But I've still never seen any kind of link that showed brain function or learning capability linked to genetics. If you take e.g. a racist they are ignorant and close-minded. They could learn (at least as kids they could have) but they chose not to. This has nothing to do with genetics, it is learned behavior.
- Daniel_Newby 16y ago"But I've still never seen any kind of link that showed brain function or learning capability linked to genetics." This paper says IQ has 70% heritability, based on a twin adoption study. http://www.ncbi.nlm.nih.gov/pubmed/2218526 http://www.ncbi.nlm.nih.gov/pubmed/2218526 Other twin studies have found 75-90% heritability for attention deficit disorder. Schizophrenia is moderately heritable. Migraine is well-known for running in families.
- robryan 16y agoIf this were true then over time humans would never have evolved to be as intellectually capable as we are. Why can we do so many things ape's can't yet have a common ancestry? It is defiantly learned behavior how you want to make use of the capability but as plenty of people with learning difficulties would attest, if the underlying function isn't as strong as in others it makes it a whole lot harder to learn even with the motivation.
- loewenskind 16y agoBut we're not talking about mental handicap here. We're talking about normal functioning people who make stupid decisions. I don't think genetics has anything at all to do with that and I've never seen anything that would make me believe it does. Given that, the only negative influence such people have by breeding is the influence they wield over their children (which can be a lot, but can also be overcome).
