In any case, we’re still trying to unpick the resulting tangle in our thinking and attitudes. Clearly, evolutionary genetics has much to teach, and sometimes the facts revealed by this science can be uncomfortable, meshed as they are with reactionary and fascist ideologies. It seems dangerous, however, to shirk the difficult job of picking these facts and values apart and, as some on the far academic left seem to, sideline the facts. On the other hand, when leftist constructionism is combatively countered with evolutionary psychology, there’s a great risk of being naive about the reactionary social values meshed into the scientific facts. This fosters a polarised conceptual space where there’s little room for improving our understanding of the subtle interactions of nature and nurture.
