I seem to sense different usage of the phrase "social interest". Your usage seems to refer to the interest in interaction with that which is external to self. My usage seems to refer to interest in the well being of that which is external to self, contrasted with personal interest. My point seems to be that although interest in interaction seems innate, including vocalizing as a social communication system, interest in the well being of that which is external to self seems not to develop unless externally introduced, and seems to deteriorate unless externally reinforced.

Re: "We evolved empathy to survive as a species", many life forms seem reasonably suggested to survive without empathy. Upon what basis might you suggest that humans have needed empathy in order to survive as a species?
