The Myers-Briggs Type Indicator has been with us since the 1950s. Fairly or not, it has been used as a window into how people work, employed by human resources departments in recruitment, advancement and firing since the middle of the 20th century. The 16 "types" focus on Jungian psychology as a foundation for understanding the "parts" of one's mind. Once these parts are classified as having specific characteristics, a four-letter acronym is used to categorize the types. 

While the methods used by Myers-Briggs analysis have their detractors and competitors, they endure, with uses not only in the corporate world. Myers-Briggs types are used by some online dating sites, matchmakers and as part of membership exams by private clubs.

While the types were designed around how the human mind works, animal minds are not that different from human minds, in key ways. What if we used the methods of Myers-Briggs to classify you, and then run that classification through the available literature comparing the human mind to the "reptile brain" of the lower species? What predatory animal would result from a comparison of your Myers-Briggs type with our neighbors at the top of the food chain? Take this quiz to find out!
