This manual predates the now world famous Myers-Briggs Personality Test (Myers–Briggs Type Indicator, or MBTI), which has been used in over 100 countries to categorize individuals based on patterns of their behavior and to label them based on their naturally occurring differences.
A very rare piece of history was published in 1921 and was distributed to the U.S.A’s public schools long before Myers created her personality test in 1962.
The manual was used in schools to measure the intelligence of children and mark the ones with “native capacities” and traits that made them appear more gifted than others.
This is a very scarce hardcover antiquarian in fine condition with Ephemera included.
