What is 16Personalities?
16Personalities is the world's most popular personality test, based on the Myers-Briggs Type Indicator framework. It assigns you one of 16 types (like INTJ or ENFP) based on four dichotomies: Introversion/Extraversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving.
You answer a series of agree/disagree questions and are assigned one of 16 personality types based on four binary preferences. Results emphasize your type label and associated traits.
