I'm really looking to see if any work has been done on this area and where I could find it, or if my terminology is correct. Assuming a very abstract concept of human interaction, how does one measure equivalency.
For example, given the existence of a group of people, at what point is another group of people considered an equivalent group to interact with?
Are there broad measures or definitions of group equivalency? I appreciate that some readers may say this question is too broad but a central tenet of sociology and politics is how groups interact so how do sociologists make comparisons other than arbitrary ones. Clearly a parish choir group is not an equivalent negotiator with EMI for a record contract.
Or perhaps I am missing the point and equivalency is measured by the fact that an interaction happened or that there was an effect on the groups in the interaction.
So then to measure group equivalency should we be working backwards to measure the effects on the groups and given a certain effect we could say there was equivalency?
