The Big Five refers to five factors that describe how people interact with the world: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism. Just by reading about the Big Five and considering your own behavior, it is pretty easy to tell whether you fall on the high end or the low end, or somewhere in the middle, of the five dimensions.
