I had to look up "social negotiation" to fully understand this sentence in context. From Fandom, "Social negotiation is a subset of the first class collaborative element, cultural negotiation, which is itself a subset of information exchange. The amount and type of social negotiation involved in a collaborative process is linked to the characteristics of the collaborative media and the participants." Here is the source if you are baffled with the language as I am: https://collaboration.fandom.com/wiki/Social_negotiation#:~:text=Social%20negotiation%20is%20a%20subset,collaborative%20media%20and%20the%20participants.
