They say that every person is unique, but apparently not. Researchers at Northwestern conducted a study of over 1.5 million people and identified four major “clusters” that people fit into.
- “Average” is the largest group, with people who tend to be neurotic and extroverted, but not very open.
- “Reserved” people are more emotionally stable but tend to be more introverted.
- “Role Models” are dependable, less neurotic, and make better leaders. As people age, more of them fit into this category.
- “Self-Centered” people are highly extroverted but lower in most other categories. Teenagers are frequently in this category and many people eventually age out of it.
