Isabel Briggs Myers
Isabel Briggs Myers was an American writer and researcher who developed the Myers–Briggs Type Indicator with her mother, Katharine Cook Briggs.
Myers–Briggs Type Indicator: A personality questionnaire that assigns one of 16 types using four pairs of psychological preferences. Myers and her mother developed this instrument to put their interpretation of personality preferences into practice.
Carl Jung: A Swiss psychiatrist who founded analytical psychology and proposed influential theories of psychological types. Myers and Briggs drew on Jung’s ideas about introversion, extraversion, and mental functions.
Peter B. Myers: An American psychologist and son of Isabel Briggs Myers who continued work on the Myers–Briggs Type Indicator. He helped carry forward his mother’s research and the instrument’s development after her death.
Big Five personality traits: A widely researched model describing personality through openness, conscientiousness, extraversion, agreeableness, and neuroticism. Unlike Myers–Briggs types, the Big Five represents personality as graded dimensions supported by extensive empirical research.
Katharine Cook Briggs: An American researcher who developed a system of personality types with her daughter, Isabel Briggs Myers. Briggs began the personality research and collaborated with Myers on the indicator.
World War II: A global war fought from 1939 to 1945 between the Allied and Axis powers. Myers began developing the questionnaire during the war, hoping it could help people find suitable work.
Naomi Quenk: An American psychologist and author known for writing about the Myers–Briggs Type Indicator and type development. Her publications helped extend Myers’s framework into guidance and popular interpretation.
Trait theory: An approach to personality that describes people through relatively stable, measurable characteristics. Trait models treat personality differences as continuous scores rather than Myers’s categorical preferences.
Psychological Types: Carl Jung’s 1921 book proposing that people differ in psychological functions and attitudes. Jung’s typology supplied the theoretical foundation Myers and Briggs adapted.
Isabel Briggs Myers Papers: A collection of Myers’s writings and records documenting her life and work on personality assessment. The papers preserve drafts and correspondence tracing the indicator’s development.
