Abstract
In order to avoid the communication conflicts due to the misunderstanding for the discussed issue by the participants who are not used to the public discourse, a facilitator is often set at the meeting for community issue discussed by the inhabitants. This study purposes to clarify the influence of facilitator's discourse management on participant's perception for the conclusion. A discourse experiment conditioned by positive / routine facilitation is made to get the discourse records with the discourse evaluation by the participants, collected by the post-discourse questionnaire survey. A decision tree analysis showed that the higher evaluation for the participant's perception for discussion conclusion can be induced by a positive discussion management of the facilitator when he or she evaluates the self-contribution to the discourse as significant. However, when he or she evaluates the self-contribution to the discourse as insignificant, a positive discussion management of the facilitator would decrease the participant's perception.
