If the ongoing fascination with astrology, personality tests, psychics, and the like is any indication, humans are innately curious creatures who are constantly trying to understand themselves. The Myers-Briggs personality test, in particular, has remained popular since its creation back in the 1950s—perhaps because its simple four-letter categorization is simple and intelligible enough for anyone to understand.
Of course, some of the 16 different personality types are more common than others. As Bustle reports, INFJ, which stands for introversion, intuition, feeling, and judging, is the rarest type, with roughly 1.5% of people who take the test scoring this elusive four-letter combination. This statistic comes straight from The Myers & Briggs Foundation itself.
INFJs are described as "idealists" and are both creative and fair-minded people who see the world "not the way it is, but the way they think it should be," explains the publication. "INFJs are big-picture thinkers. Rather than help individuals, they look for ways to change the system."
Ann C. Holm, a life coach and psychologist from the University of Michigan, believes that INFJs have highly complex personalities, and even dubs them "mysterious." "INFJs are deeply concerned about their relations with individuals as well as the state of humanity at large," she writes on her blog. "They are, in fact, sometimes mistaken for extroverts because they are so genuinely interested in people. Yet, INFJs will suddenly withdraw into themselves, sometimes shutting out those closest to them."
She regards this habitual "about-face" as the "most confusing aspect of the enigmatic INFJ character," she explains. "They are like Russian nesting dolls. When one doll is exposed, another one lies inside."
