I’ve delved quite deep into MBTI, enough to feel comfortable typing by cognitive functions, which are somewhat arbitrary cognitive preferences defined by Carl Jung in his book Psychological types (I haven’t read it). It turns out the inventors of MBTI, Isabel Myers and Katharine Cook Briggs (mother and daughter), were looking to simplify these functions into dichotomies that would ultimately lead to the 16 types we know today. This is relevant in that MBTI, unlike Jung’s cognitive functions, fails to allocate an order of preference to its dichotomies.
For example it’s impossible to tell which of Extraversion, iNtuition, Thinking or Judging is preferred by ENTJs in their decision making. According to Jung, ENTJs cognitive functions are, in order of preference, Te (extroverted thinking), Ni (introverted intuition), Se (extroverted sensing) and Fi (introverted feeling).* Thus, ENTJs’ Te makes them prioritize decisions that will have an impact on their external environment, no matter the emotional cost (Fi being their most neglected function).
“Chronically online” people like mass identifiers (me included) tend to self-report as INTP, INTJ, INFP or INFJ. I could personally see ESTPs and ISTPs as mass observers, since they both have Se (extroverted sensing) and Ti in their first 2 function slots. ISTJs and ENTPs, while polar opposites in terms of cognitive functions, tend to enjoy categorizing things, so they’d probably be some of the most prolific identifiers on iNat
*Note: Jung’s cognitive functions can be either introverted (directed toward the self/internal satisfaction) or extroverted (directed toward others/external satisfaction). This is denoted either with “i” or “e” after each letter of a function. For example, introverted feeling is noted “Fi” and extroverted feeling “Fe”. This makes for 16 cognitives functions in total
