Katharine Cook Briggs: The Woman Who Revolutionized Psychology

While raising her daughter Isabel, Katharine developed a system to understand different personality types through careful observation of children’s development patterns. Her fascination with Carl Jung’s theories led to collaborative work with Isabel creating the Myers-Briggs Type Indicator. She home-schooled Isabel with innovative educational methods that encouraged analytical thinking. Their mother-daughter research partnership created one of the world’s most widely used psychological assessment tools.
