An interesting observation is that the PUA community also refers often to the Keith Johnstone book as a "primary source" for their list of supposed high-status behaviors. (I'm guessing that's where Robin Hanson picked up the reference.) Johnstone's own inspiration was Desmond Morris of Naked Ape fame; at least that much is tracking for me. On the other hand, Johnstone himself is no scientist, but a drama instructor.

It would be more accurate to say Johnstone's book is a "primary inspiration". The examples of high status behaviors given actually tend to be based off a combination of personal experience, cultural learning and wider reading in evolutionary and social psychology. Cialdini is also commonly referenced, as is Dawkins. In fact, references range as far as animal training guides, with the caveat that experience and discretion is applied in working out which of the status moves apply even across the boundaries of species.
