Katharine Briggs and Isabel Briggs Myers

Katharine Cook Briggs and her daughter Isabel Briggs Myers developed a personality type indicator influenced by ideas in psychology, especially Carl Jung's theory of psychological types. Their work eventually became the Myers-Briggs Type Indicator, commonly known as the MBTI.

Isabel Briggs Myers (18 October 1897 – 5 May 1980) developed and organized many of these ideas into a practical questionnaire. Over decades, the framework was refined into a system describing different personality preferences.

What is the idea of personality type?

The type framework describes four pairs of preferences: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. Combining the four preferences produces 16 possible four-letter types. An important principle is that no personality type is inherently better than another.

Traditional type descriptions often discuss communication style, decision-making, work preferences and everyday habits. They can be useful prompts for self-reflection, but they should not be treated as predictions of career success or as clinical conclusions.
