The motivational basis of concessions and compromise: archival and laboratory studies.

A content analysis system for measuring positive concessions (offering concessions) and negative concessions (rejecting offered concessions) was introduced and validated through an archival study of government-to-government documents from 4 crises, 2 of which escalated to war and 2 of which were peacefully resolved. In the archival documents, concession making was positively associated with affiliation motivation and negatively associated with power motivation. A 2nd, laboratory experimental study confirmed these relationships and demonstrated priming effects of motive imagery and concession making, in a received diplomatic letter, on participants' responses. Finally, the motive imagery and concessions scores in participants' responses were related in predicted ways to their policy choices.
