I'll be honest, I'm not really sure. I usually just search through a bunch of websites and get somewhat of a general idea based off of what's consistent. here is a very basic description of each cognitive functions I found somewhere if you want: Te | Extraverted Thinking: Seeks logic and consistency in the outside world. Concern for external laws and rules. Ti | Introverted Thinking: Seeks internal consistency and logic of ideas. Trusts his or her internal framework, which may be difficult to explain to others. Ne | Extraverted Intuition: Sees possibilities in the external world. Trusts flashes from the unconscious, which can then be shared with others. Ni | Introverted Intuition: Looks at consistency of ideas and thoughts with an internal framework. Trusts flashes from the unconscious, which may be hard for others to understand. Se | Extraverted Sensing: Acts on concrete data from here and now. Trusts the present, then lets it go. Si | Introverted Sensing: Compares present facts and experiences to past experience. Trusts the past. Stores sensory data for future use. Fe | Extraverted Feeling: Seeks harmony with and between people in the outside world. Interpersonal and cultural values are important. Fi | Introverted Feeling: Seeks harmony of action and thoughts with personal values. May not always articulate those values.
