Social Dynamics dictates that everything changes in a social setting. Ie. it's dynamic everyone has a different set of variables that can happen in a given night, given the right stimulis, you can sway things either way.
Social Selection is where you take the trade of the craft and apply it, shaping the interactions, using the loops to your advantage. Employing the help of Guided visualization to build rapport and shape the interaction to your best interest.
Couple this with value elicitation to get their core words as I call them other have different name.
and BAM. you are employing social selection in the best way possible, you are building and shaping the social dynamic in a way it is less dynamic in regards to your variable. You can select the variables you wish to change and those changes change other people which in turn can change to your benefit.
Not only do you waste less time in your interactions, you are able to know what type of values to lok for in a potential mate for either long term or for the night.
Social Selection my friend.... That is where the fun lies...
