Later, she read work by Carl Jung. Jung had ideas about how people make choices. Katharine and her daughter, Isabel, studied these ideas. They spent twenty years watching how people behave.

Many people use the MBTI today. It helps with jobs and marriage counseling. Some people say the test is not true science. Still, many millions of people have taken it.

Katharine Cook Briggs was an American writer who wanted to understand people. She is most famous for helping create a personality test. This test is called the Myers–Briggs Type Indicator, or MBTI for short.

She worked on this with her daughter, Isabel Briggs Myers. Together, they helped people learn about their own characters. This work matters because many people still use the test today. It is used for things like job training and marriage counseling.

Briggs began her work by studying how children grow and learn. She wanted to find ways to help children be happy. She also wanted to help them find the right jobs. In 1917, she identified four main personality types. These were called meditative, spontaneous, executive, and sociable types. Later, she read the work of a man named Carl Jung. Jung had ideas about how people take in information. Briggs used these ideas to build her own theories. She and Isabel spent twenty years watching how people behave.

Katharine was born on January 3, 1875, in Ingham County, Michigan. Her father, Albert John Cook, taught at a college. She was homeschooled for a long time. She did not go to a formal school until she was fourteen. After college, she earned a degree in agriculture. She also worked as a teacher for a while. Later, she married a physicist named Lyman James Briggs. They had one daughter named Isabel, who was born in 1897.

Briggs and her daughter did many important tests. In 1945, they tested students at George Washington Medical School. During World War II, Isabel made a test for war jobs. Isabel eventually turned their ideas into a paper and pencil test. This test puts people into 16 different personality combinations. Since 1962, the test has been part of a large collection. It is estimated that 50 million people have taken it.

Learning about personality can feel like looking in a mirror. The MBTI helps people see how they make choices. Some people call the test pseudoscience. They think it was made at home without enough scientific research. However, the framework of the test has stayed the same since it began. It helps people understand why they act the way they do. This connects to how we all try to understand our friends and family.

Katharine Cook Briggs was an American writer and researcher. She is best known as a co-creator of the Myers–Briggs Type Indicator, or MBTI. This is a popular system used to categorize human personality types. While some critics label the system as pseudoscience, it remains widely used in many fields. It is applied in areas such as marital counseling and executive development. Briggs worked alongside her daughter, Isabel Briggs Myers, to bring these ideas to life.

Briggs’ journey into personality research began with a focus on children. She studied theories regarding how children develop socially and educationally. She believed that a child's future happiness depended on finding the right vocation, or career path. In 1917, she identified four primary personality types. These were the meditative, spontaneous, executive, and sociable types. These early categories later evolved into the technical terms used in the MBTI. She wanted to use these findings to help children find their way in the world.

Her interest in human behavior was also driven by her creative writing. Briggs attempted to write fiction and wanted to create richer, more believable characters. To do this, she studied the specific details of human personality and behavior. This led her to explore the works of various philosophers, scientists, and psychologists. However, she struggled to find a single, definitive theory of type. This lack of a unified theory inspired her to develop her own unique framework. She wanted a system that could encompass all aspects of human nature.

In 1923, Briggs discovered the work of the Swiss psychologist Carl Jung. Jung’s theories focused on innate differences in how people process information. He also studied how people make decisions. Briggs was so inspired by his book, *Psychological Types*, that she changed her research direction. She moved away from her own original theories to study Jung’s ideas more deeply. Eventually, her daughter Isabel joined her in this research. Together, they engaged in a twenty-year period of "type watching" to observe human behavior firsthand.

Briggs and Myers developed the MBTI through many practical assessments. In 1945, they conducted an assessment on students at George Washington Medical School. During World War II, Isabel created a test to help identify appropriate jobs for people during the war. While Katharine provided the primary inspiration and driving force, Isabel acted as the workforce. Isabel turned their combined observations into a physical pencil and paper questionnaire. The final system classifies people into 16 possible combinations of personality types. These types are based on four pairs of categories, where each person has a dominant preference.

Briggs was born on January 3, 1875, in Ingham County, Michigan. Her father, Albert John Cook, was a faculty member at Michigan State University. Her mother, Mary Harris Baldwin, attended Oberlin College. Briggs was homeschooled by her father for much of her early life. She did not enter a formal school until she was fourteen years old. After college, she earned a degree in agriculture and worked as a teacher. She later married Lyman James Briggs, a physicist who directed the Bureau of Standards in Washington, D.C. They had one daughter, Isabel, who was born in 1897.

Since the MBTI was added to the Educational Testing Service collection in 1962, it has become a global phenomenon. It is estimated that 50 million people have taken the assessment. The fundamental framework of the test has remained largely unchanged since Briggs first developed it. Some scientists criticize the MBTI, arguing it was developed at home rather than through extensive scientific research. Despite these criticisms, the tool continues to connect people to broader ideas about psychology and self-awareness. It remains a significant part of how many people approach the study of human character.
