According to the "Big 5" or 5-Factor Model, there is a small core of traits that best captures people's "personality." These 5 factors (Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism - or "OCEAN") consist of several smaller sub-factors. Advocates of this model argue that once you know where someone falls on the Big 5, you get a pretty accurate picture of the "essence" of their personality.

What do you think of this model? Do you agree with it? What aspects of personality do you think are neglected by the 5-Factor Model? Can you find a place for these neglected aspects within the model? That is, how do you think the Big 5 folks would counter the criticism that it leaves out certain aspects of personality? Are there any aspects of personality that absolutely cannot be "fitted" into the 5-Factor Model? Why/why not?
