The experimental evidence for a purely genetic component of 0.6-0.8 is overwhelming
Erm. 0.6-0.8 what?
-Robin
I assume he means an R or an R^2 of 0.6-0.8. Both are measures of correlation. R^2 would be the percent in the variation of one twins intelligence predicted by the intelligence of the other twin.
Probably 60-80% heredity. But that is also meaningless, because I have no idea which population it refers to.
