Labels give meaning to what is messy and confusing. Struggles with complex emotions demand an explanation — a tangible reason for what is most troubling. Personality tests offer the allure of certainty, with the implicit promise of eradicating the messiness and chaos. They provide a sense of identity and belonging to a group (hey, we’re all introverts here!) and distinguish one group of people from another. A quick explanation of differences makes life seem so much easier.
