Many of these "everything is instinct and there is nothing good" arguments reveal more about the underlying psychological state of the person claiming such supposition than factual or scientific knowledge. These are like Rorschach ink blots. The imputed motive upon others is but a projection of their internal state and their fundamental perspective of the external environment.

In almost all instances of "science" being used to justify certain sociological or moral conclusions, the person already has an ingrained bias that he attempts to proselytize upon others. It is a form of insecure religious fanaticism gussied-up in pseudo-scientific drivel.
