The opposite dichotomy of an introspective is an expressive. This is someone who by the time a decision to move forward has been made, it’s almost immediately spontaneous and reflexive. The decision to take action is usually directed toward the outer world. The action is expressive, meant to interact with the world and people around them. It’s purely an external action. For an expressive, there might be some time that a thought process is internalized but ultimately it has to manifest outward and interact with someone, somebody to be “real”. Seeking a response, feedback, tactile information. An expressive seeks to affect the environment or at least be a part of it.
