Nice work, @
Olga.
Thanks for posting it, looking forward to the rest!
Btw, I am wondering what you mean here:
You are saying that we attract dual partners based on our facial expresions? I personally find certain female ESI facial expressions often charming, so there could something to this idea. It's a certain type of facial expression for ESI that I find attractive, not all of the expressions since there more than one for each type, I think.
Could you perhaps get into more detail about how a person can repel compatible partners if they don't have the facial expressions typical to their type?
