  Agile requirements engineering implies more complex communication patterns
since even the developers are supposed to have direct contact with customers.
With more face-to-face communication comes social-psychological factors
influencing the requirements. Studies have pointed at the importance of
negotiation training, but I argue that more basic human traits can be triggered
in favor of the negotiator with the most knowledge of social influence research
and practice. I suggest a plan of how research in social influence and
requirements facilitation can be conducted, mostly through experimentation.
