Propagating Genes VS Memes
I have been a bit negative about memes, but they have their cheerful side as well. When we die there are two things we can leave behind us: genes and memes. We were built as gene machines, created to pass on our genes. But that aspect of us will be forgotten in three generations. Your child, even your grandchild, may bear a resemblance to you, perhaps in facial features, in a talent for music, in the colour of her hair. But as each generation passes, the contribution of your genes is halved. ...Our genes will only last in recognizable form for three generations or so, being halved with each generation; our memes, however, have the potential to live far beyond our lifetimes and have greater influence.

IQ is Malleable
IQ is malleable. IQ has been shown to vary over one’s life span, and it is surprisingly vulnerable to environmental influences. It can change if one is stressed, old, or living in a different culture from the testing majority. A child’s IQ is influenced by his or her family, too. Growing up in the same household tends to increase IQ similarities between siblings, for example. Poor people tend to have significantly lower IQs than rich people. And if you are below a certain income level, ec...A poor child adopted into a middle-class family will gain 12 to 18 IQ points.
