This Project is a reimplementation of the MBTI (Myers Briggs Type Indicator) - Personality Test which is a quiz formally taken to make an objective assessment of one's personality. I say this is a reimplementation because the original MBTI implementation uses an undisclosed algorithm based on Carl Jung's theory of Personality Types rather than a primitive intelligent systems algorithm such as the Mamdani Fuzzy Inference Engine.
The MBTI questionnaire assesses the taker of the quiz based on four dichotomies, namely:
Introversion / Extroversion Sensing / Intuition Thinking / Feeling And Judging / Perceiving
Each of these dichotomies can be grouped in 16 ways based on how the user is assessed for each dichotomy.
For instance, an introvert with sharp intuition, critical thinking and judgment may classify under INTJ.
In order for a more accurate representation of the MBTI, I implemented the Mamdani Fuzzy Inference engine four times for each dichotomy.
Each dichotomy is assessed by 4-5 input variables and their respective membership functions as follows:
