Abstract: Optimistic Intelligence Quotient or Optimistic Intelligence is the ability of optimism, which includes not only the level of a person’s optimism, but also a person’s ability of acquiring the positive compositions from his negative experiences that he had as well as the ability of influencing or affecting the people around. ‘Duchenne Smile’ is a main form of expression of high OQ. The relevant research about psychology in the past proves that high OQ not only is beneficial to the social development of a person, gaining a stable happy marriage, the improvement of a person’s physical health, the improvement of academic performance, decreasing the occurrence of bad things, but also benefits a person’s pursuit of social support and interaction. All these research results show that OQ is likely to be an aspect playing a more important role in destiny than IQ and EQ.

Key words: Optimistic Intelligence Quotient, Duchenne Smile, positive strength, Attributional Style Questionnaire
