Conflict resolution involves facilitating a peaceful end to conflict through communication and collective negotiation. There are a variety of conflict resolution methods, including negotiation, mediation, diplomacy, and peacebuilding. Conflict resolution styles are informed by individuals' level of concern for themselves and others, with cooperation seen as the most effective style as it involves finding solutions agreeable to all parties. Culture also influences approaches to conflict resolution, as direct communication may be considered rude in some cultures.
