He decided to study psychology more in-depth after struggling with his own personality. He often felt like he was two different people (Cowgil 3) Carl Jung’s “Type Theory” was the inspiration for the MBTI (Zemke 2), stating that behavior is “individual and predictable” (Plonk 12). Jung’s Theory focused mainly on introversion and extroversion. He believed that a healthy person would be able to use both of those traits when necessary (Cowgil 7). Briggs and Myer expanded on his list of types by adding three other pairs of traits.
