Two housewives, Katherine Briggs and her daughter Isabel, who had been investigating human personality traits around Katherine's kitchen table in the early 1920s, were excited when the psycologist and psychiatrist Carl Jung published his 1923 book on the same subject. They took his findings to a new level, extrapolating his theories to create a repeatable personality preference survey, finally producing the famous Myers-Briggs Type Indicator which is widely used in psychological and employment testing today. Katherine started her research partly as a result of being disgusted with the waste of war, during WWI, thinking there must be a better way for men to resolve their disputes.
Katherine was home schooled and home schooled her daughter Isabel as well. Isabel's father, Lyman Briggs, worked in the field of physics, being director of the Bureau of Standards in Washington. Isabel grew up in Washington and later attended Swarthmore College, earning a degree in political science, She met her husband of 61 years, "Chief" Clarence Myers. during college.
Like her mother, Isabel was concerned with stopping conflict among people, and intensified her research when WWII came. She was allowed to test over 5000 students at George Washington University, and studied the results for years, looking for patterns among dropouts and successful students.
I'm guessing she was an intuitive since she was so fixated on patterns.
Ok, so they were very educated housewives.
