While quizzes are usually considered back-of-magazine fodder, the Myers-Briggs Type Indicator personality test is more than just a fun game. The self-report questionnaire is based on a theory by psychoanalyst Carl Jung and aims to identify the responder's personality based on 16 set types. It's estimated that a whopping two million people take the test each year, which gives the Myers & Briggs Foundation access to a ton of data about responders.
According to Bustle, the rarest personality type is "INFJ," which stands for introversion, intuition, feeling, and judging. Just over 1% of people receive this score. Dubbed "the advocate personality," this type differs from others, thanks to a unique mix of qualities. People with this type "have an inborn sense of idealism and morality, but what sets them apart is that they are not idle dreamers, but people capable of taking concrete steps to realize their goals and make a lasting positive impact," explains website 16Personalities.
While rare, Bustle points out that there are a number of notable world leaders who fall within the INFJ type. Martin Luther King Jr., Hillary Clinton, Nelson Mandela, Woodrow Wilson, Dwight D. Eisenhower, Al Gore, and Susan B. Anthony are all believed to share these rare traits. If your Myers-Briggs score is INFJ, you could well be destined to lead.
