A brand new Northwestern study has found that there are basically four different personality types in the world, and you almost certainly fall into one of the categories.
They are...
Average: Average people are high in neuroticism and extraversion, while low in openness. This is the most common personality type.
Reserved: The Reserved type is emotionally stable but not open or neurotic. They are not particularly extraverted but are somewhat agreeable and conscientious.
Role Models: Role models score low in neuroticism and high in all the other traits. They are good leaders, dependable and open to new ideas.
Self Centered: Self-Centered people score very high in extraversion and below average in openness, agreeableness, and conscientiousness.
I can't figure out which one I am.
