i never had Sheptoski, but I think the goal of social psychology isn't to tear down the established primate social order, but simply to study and recognize it as a fact of life.

When human beings aren't Homo sapiens sapiens any more, maybe social interaction will make a greater departure from our ape roots. Until then, I don't think humans are doing too bad. At least we realize how similar we are to monkeys and apes. That's pretty good for an animal.
