[单项选择] Conventional wisdom about conflict seems pretty much cut and dried. Too little conflict breeds apathy and stagnation. Too much conflict leads to divisiveness and hostility. Moderate levels of conflict, however, can spark creativity and motivate people in a healthy and competitive way.
Recent research by Professor Charles R. Schwenk, however, suggests that the optimal level of conflict may be more complex to determine than these simple generalizations. He studied perceptions of conflict among a sample of executives. Some of the executives worked for profit-seeking organizations and other for not-for-profit organizations.
Somewhat surprisingly, Schwenk found that opinions about conflict varied systematically as a function of the type of organization. Specifically, managers in not-for-profit organizations strongly believed that conflict was beneficial to their organizations and that it promoted higher quality decision-making than might be achieved in the absence of conflict.
A. the advantages and disadvantages of conflict
B. the difficulty in determining optimal level of conflict
C. the complexity of defining the roles of conflict
D. the real value of conflict
