There are apparently only four personality types that everyone falls into – average, reserved, self-centered, role model.
After studying over a million people worldwide here is how they decided what people were:
An average personality type was someone with a high in one end like extroversion and neuroticism, while low in another way like openness.
Meanwhile reserved type people were emotionally stable, but not open or neurotic.
Then there are the role models score low in neuroticism and high in all the other traits
Finally there are the self-centered people score very high in extroversion and below average in openness, agreeableness and conscientiousness.
