6. Big 5 Personality

Not that anyone should agree with boiling your personality down to just a number, but many psychologists these days believe that you can boil your personality down to just a number.
The "Big 5" refers to the five major personality traits which, when combined in different quantities, can produce a broad spectrum of personality types. These five traits are generally believed to be extraversion, agreeableness, openness (sometimes referred to as Imagination), conscientiousness and neuroticism (sometimes Emotional Stability).
The extent to which you possess each of these traits supposedly form the central pillars of your personality - although, as personality is a complex not little understood phenomenon, results should be taken with a healthy pinch of salt.
