There is a massive industry that revolves around people trying to figure out what makes them tick. We want to know our strengths and weaknesses so that we can hopefully go about contributing to the world. Some of the most popular tools for exploring these aspects are the Enneagram (I’m a type 9) and the Myers-Briggs Type Indicator (INTP or INFP depending on when I have taken it). Yet there is another way of assessing personality types that has been used by amateur clinicians on elementary school playgrounds since the late 1980s: the Teenage Mutant Ninja Turtles.
For the poor folks who don’t know about these modern mythological heroes, Teenage Mutant Ninja Turtles is about four brothers who are—follow me closely here—teenaged mutant turtles who practice martial arts. For multiple generations of children, TMNT have been featured in countless cartoons, video games, and movies including a delightful film that just came out this week. And from the beginning, kids would find themselves drawn to either Leonardo, Donatello, Raphael, or Michelangelo.
The Teenage Mutant Ninja Turtle Personality Index (TMNTPI) seeds to codify what these playground and dorm room conversations have been doing for years: helping people figure out their strengths and weaknesses based upon the turtle with which they most identify. This is not necessarily your favorite turtle though your favorite may be the one with which the TMNTPI links you. Also, most of us will actually have aspects of all the turtles. Yet there is typically one that is strongest.
