"Heritability" is misleading and correlations don't hint

Genetics and Reductionism by Sahotra Sarkar, pp 12-13:
high [narrow] heritability, which is routinely taken as indicative of the genetic origin of traits, can occur when genes alone do not provide an explanation of the genesis of that trait. To philosophers, at least, this should come as no paradox: good correlatoins need not even provide a hint of what is going on. They need not point to what is sometimes called a "common cause". They need not provide any guide to what should be regarded as the best explanation.
I already knew that. :-)
