Omnivert
What is an omnivert?
“Omnivert” is an informal label for someone who describes themselves as very outgoing in some situations and withdrawn in others. It should not be treated as a clinical diagnosis or a test result from an established assessment simply because the description feels familiar.
Omniversion is the corresponding informal name for this described pattern. For example, someone might be very talkative with close friends and quiet in an unfamiliar group. The label describes that variation; it does not establish a separate type in the MBTI or Big Five.
What the research supports
Fleeson’s experience-sampling research found substantial changes in individuals’ everyday personality-related behavior alongside stable differences in their average tendencies. That supports distinguishing a person’s usual pattern from how they behave at one moment.
This evidence does not establish a separate omnivert personality type. A person can describe when they seek company or solitude without inferring a distinct category.
