I've always been interested in how certain people's minds work differently than most. According to David Keirsey's research, the
INTJ personality type is one of the rarest in psychology. These analytical thinkers make up only 1% to 4% of the population. This is even more true for women, as INTJs make up only 1% of the female population.
It's not just that INTJs are rare that makes me want to learn more about them. It's the contradiction they show.
People like this frequently seem like "walking encyclopedias," able to learn a lot of material from many different areas very quickly. The title "Mastermind" does capture something important about how they think strategically, but it doesn't even begin to cover how complicated they are. Isaac Newton, Stephen Hawking, and Hillary Clinton all have this kind of mind, yet they all show INTJ tendencies in very different ways through their work in science and politics.
My observations have demonstrated time and time again that INTJs don't fit into simple categories. They are different from other analytical types since they can think beyond the box and put their ideas into action. Their brains are like advanced pattern-recognition algorithms that are always looking for links that other people miss.
The truth is more complicated than the stereotypes make it seem.
The next sections go into the real workings of the INTJ mind, including its cognitive functions, core qualities, relationship patterns, and career interests. If you see yourself in these patterns or want to learn more about someone with this personality type, you'll find information that goes beyond the simple "mastermind" image that often oversimplifies these amazing people.
