I scored ISTJ when I took Myers-Briggs. The I and T scores were very extreme, while the S and J scores were more moderate.
I just took the Enneagram Sampler and scored a three-way tie between type 1, type 3, and type 5.
Quote:
Type One: The Reformer
The principled, idealistic type. Ones are conscientious and ethical, with a strong sense of right and wrong. They are teachers, crusaders, and advocates for change: always striving to improve things, but afraid of making a mistake. Well-organized, orderly, and fastidious, they try to maintain high standards, but can slip into being critical and perfectionistic. They typically have problems with resentment and impatience. At their Best: wise, discerning, realistic, and noble. Can be morally heroic..
Type Three: The Achiever
The adaptable, success-oriented type. Threes are self-assured, attractive, and charming. Ambitious, competent, and energetic, they can also be status-conscious and highly driven for advancement. They are diplomatic and poised, but can also be overly concerned with their image and what others think of them. They typically have problems with workaholism and competitiveness. At their Best:: self-accepting, authentic, everything they seem to be—role models who inspire others.
Type Five: The Investigator
The perceptive, cerebral type. Fives are alert, insightful, and curious. They are able to concentrate and focus on developing complex ideas and skills. Independent, innovative, and inventive, they can also become preoccupied with their thoughts and imaginary constructs. They become detached, yet high-strung and intense. They typically have problems with eccentricity, nihilism, and isolation. At their Best: visionary pioneers, often ahead of their time, and able to see the world in an entirely new way.
