According to researchers, the INFJ Myers-Briggs type occurs in about 1% of the population—the lowest prevalence of any type. Studies vary regarding the exact percentages of the 16 types, but INFJs always walk away with the prize for the most rare.
The downside of being an INFJ is that there are few people out there with whom they can relate deeply. Also, they don’t fit into social norms because their qualities are unusual and, to some people, unsettling. INFJs can size up others quickly and those who don’t like to be sized up are likely to avoid them. Friends and colleagues find many INFJs almost clairvoyant.
The upside for INFJs is that they have gifts not common in other types. This makes them valued as leaders, workers, and friends. They also have rich interior lives.
In work settings, INFJs collaborate well with the second rarest type, ENTJs—also known as the CEO type. While ENTJs prefer the footlights, INFJs are happy to operate behind the scenes. Both types are intuitive; when they combine their insights they make a formidable team. INFJs can soften the edges of ENTJs, who prefer logic and rationality and are often insensitive to the feelings of others. The quiet, tactful INFJ can steer the ENTJ away from decisions that will alienate colleagues. Since the two share a Judging preference, the two types can forge productive partnerships and get a lot done.
At the other end of the scale are the three most prevalent types, shown in dark green: the ISTJ, ESFJ, and ISFJ. Each constitutes between 11% and 14% of the general population, for a total of over 35%. The ISTJ, sometimes called the Inspector, is reliable, works conscientiously, and follows rules and regulations. INFJs and ISTJs often have trouble understanding each other, probably because they have neither intuition nor feeling in common. ESFJs, called Harmonizers, are friendly facilitators. ISFJs, called Protectors, live to serve others often at the expense of their own interests. The ESFJs and ISFJs are liked and admired by most people.
