The language utilized in media each displays a tradition’s view of the world and influences how individuals throughout the tradition suppose and act, the authors say. “Hate speech” can mobilize violence and destruction, however a lot much less is understood about how “peace speech” characterizes peaceable cultures and should assist to generate or maintain peace, mentioned examine coauthor Peter Coleman, govt director of the Columbia Local weather College’s Superior Consortium on Cooperation, Battle and Complexity.
