It seems like there might be some confusion in your terminology, as "grant function type" and "Myers briggs type" are not standard concepts in the Myers-Briggs Type Indicator (MBTI) framework. However, I'll try to help you interpret your results based on the traditional MBTI type and cognitive functions.
MBTI Type: It seems like you have received three different results for your MBTI type, which could be a result of taking different online tests or inconsistencies in how you answered the questions. The standard MBTI types are represented by four letters, such as INFJ, INFP, etc. Each letter stands for a particular preference in four dichotomies: Introversion (I) or Extraversion (E), Intuition (N) or Sensing (S), Thinking (T) or Feeling (F), and Judging (J) or Perceiving (P).
Cognitive Functions: The MBTI theory is based on the concept of eight cognitive functions, which are grouped into four pairs: extraverted thinking (Te), extraverted feeling (Fe), extraverted sensing (Se), extraverted intuition (Ne), introverted thinking (Ti), introverted feeling (Fi), introverted sensing (Si), and introverted intuition (Ni). Each MBTI type is associated with a specific stack of four cognitive functions, with the dominant and auxiliary functions being the most prominent.
Given that you mentioned your highest cognitive function scores were Ni (introverted intuition) and Fe (extraverted feeling), it aligns with the INFJ type. The INFJ type's dominant function is Ni, followed by Fe as the auxiliary function.
It's common for different online tests to produce slightly different results, especially if the tests are not well-validated or if you were uncertain about your answers. To get a more accurate understanding of your MBTI type, it's best to study the cognitive functions associated with each type and determine which ones resonate with you the most.
If you strongly identify with the Ni and Fe functions, INFJ is a likely fit for your MBTI type. Remember that personality is complex, and no test can fully capture the intricacies of an individual. It's essential to approach typology with an open mind and use it as a tool for self-awareness and personal growth rather than a definitive label.
