Non-Violent Communications is a speaking style, developed by Marshall B. Rosenberg Ph.D., that greatly enhances the likelihood of getting all unmet needs fulfilled to everyone's best benefit and in a sustainable way while at the same time minimizing the likelihood that it will interfere with any other basic needs - wether it be our own or anyone else's.
It is a radical and purposeful departure from the more common speaking style that most often includes judgement, criticism, comparison, diagnoses, and interpretation of other's failings and 'badness'. This dominant speaking style, referred to with compassion and fun by NVC practitioners as 'Jackal-speak', is considered a "suicidal expression of one's own alienated needs". Jackal-speak is easily demonstrated to be the least effective way of getting any human needs met, and met in a way that is sustainable. Jackal-speak further leads to the large likelihood of disconnect between people, which too often becomes a causal factor, a slippery slope, to later physical violence.
In contrast, Non-Violent Communications (referred to as giraffe-speak) has been used with significant success at all levels of life from the personal, to the professional and organizational, as well as at the national and international level. The developer, Marshall Rosenberg, has demonstrated its significant improvements through real use in negotiating peace for major conflicts including the Rwanda Genocide, and the Israeli-Palestinian conflict. Even children's schools have noted the benefits and some are now actively teaching NVC to pupils.
