In this video we’ll explore why and how IQ differences between races are not necessarily due to genes, and how the environment can alter our intelligence. Epigenetics is revolutionizing our ideas about nature and nurture. It is no longer viable to think of our genes as being separate from our environments. Genetic expression is, by definition, controlled by where, when, and who we are. Don't fall into the Sam Harris trap of thinking that heritability is dependent solely on genes -- your inheritance comes from many other sources than the genetic blueprint you received from your parents. The metaphor of the genome as a musical score comes to mind: Someone can hand you a piece of sheet music, but the way that you play it will differ drastically depending on what instrument you play, the style you play it in, and a multitude of other factors. Genes are our sheet music, but how we play the notes is not dictated by fate. Songs: "Internal Backchat" by Ketsa
