Human beings love categorizing, labeling, and sorting things—even ourselves. Many people have come up with systems that sort us into categories based on common behavior patterns in order to better understand and interact with each other. Personality typing refers to identifying your “personality type” according to one of these systems. Some people find these labels—such as introvert, Type A, INFJ, or “The Reformer”—immensely helpful and empowering, though others find them limiting, or even used against them. Remembering that everyone’s personality is unique to themselves is more important than trying to decode those personalities—but it can be lots of fun!
There are two types of people in the world: those who believe in the Myers-Briggs personality test and those who don't. Except that's not true. Grouping people into two, three or 16 categories, which is the aim of a lot of personality tests, has never quite worked.
The leading experts in the field, Don Richard Riso and Russ Hudson have set the standard for determining personality type using the enneagram. Their studies of this ancient symbol and their progress in determining type with increasing accuracy are known, taught, and emulated worldwide.
