No fan of RJF but the Twin Studies revealed that genotype is not the entire story as to explaining behavior.

Having identical genes does not mean that those genes are necessarily expressed exactly the same for each twin. From genotype to phenotype is a complex pathway. And it is safe to assume that the greater the complexity, the more possibility for stuff to diverge.

iTwins are normally not absolutely identical, even in utero.

Epigenetic studies have demonstrated identical twins with different epigenetic markers. An example are iTwins born with different birthweights. Genomic examination show correlation with divergent epigenetic markers.

So RJF arguing that 'phagots are not born as phagots' on the merits of the Twin Studies still needs to exclude the possibility that epigenetics cannot mediate phagot behavior to be absolutely correct.
