Introverts

Judgers

Feelers

Sensors

According to the Dictionary, extrovert means to be outgoing and expressive. Therefore, I would assume that people who prefer to live in the outside world, are outgoing, and love interactions are extroverts. An introvert is more commonly shy, a judger is the decider of things, a feeler wants to find people's personalities and attitudes, and a sensor understands feelings of another.

Thus, definition-wise, extrovert is the best and most accurate answer.

They are extroverts.
