Negotiatiors are typically considered to have one of two negotiation styles: Cooperative/Problem-Solving or Competitive/Adversarial. The Cooperative/Problem-Solving style is seen as a win-win for both parties, whereas the Competitive/Adversarial style anticipates a win-lose outcome. Numerous studies support the notion that the Cooperative/Problem-Solving style is more advantageous than the Competitive/Adversarial style. Further research into negotiation styles indicates that many negotiators who characterize themselves as Cooperative/Problem-Solving are really employing a hybrid of the two styles: Competitive/Problem-Solving. The hybrid describes individuals who are respectful of their opponent, manipulative, and aware that satisfying their opponents needs and interests is beneficial for their client as well. Those that employ the hybrid style are perceived by their opponent as being completely cooperative, when in reality they act in subtly deceitful ways in order to maximum their clients gains.
