On the Evolution of Logic: An Introduction to Cognietrics

Introduction

The third letter can be T (Thinking) or F (Feeling). Thinkers mostly use logic to make decisions and Feelers mostly use their emotions. According to Anthony Jack of Case Western Reserve University, evidence suggests that empathy and thought repress each other's use. (https://www.sciencedaily.com/releases/2012/10/121030161416.htm)

The fourth letter can be P (Perceiver) or J (Judger). Perceivers like to leave their options open (Pe) and tend to improvise spontaneously (Ji), and Judgers like to make decisions early (Je) and tend to plan conditionally (Pi). According to Isabel Briggs-Myers, Perceivers primarily iNtuit or Sense in an extraverted way, and Judgers primarily Think or Feel in an extraverted way, depending on which second and third letters are chosen.

Eighty-nine of the Fortune 100 companies now use the MBTI in some form, "to maximize individual and team effectiveness from entry to executive levels". (https://www.cpp.com/products/mbti/index.aspx)

Usually the best Relationship is said to occur between Types that have completely opposite letter designations (since opposites can attract).

Websites such as celebritytypes.com have been known to guess the personalities of famous cultural icons. Others try to determine the best travel destination for each personality.

The rarest Type in the population as determined by the Myers Briggs Foundation is the INFJ at 1.46%. The most common Type is the ISFJ at 13.8%. (http://www.statisticbrain.com/myers-briggs-statistics/)

The Type that has the highest ratio of representation in gifted classes to representation in normal classes as determined by Ugar Sak of the University of Arizona is the INTP at 3.40:1. (home.anadolu.edu.tr/~usak/documents/PsychologicalTypesofGiftedAdolescentspublishedinJSGE.pdf)

The Type that tends to earn the most as determined by Truity Psychometrics is the ESTJ with an average of $77,000/year. (http://tech.co/myers-briggs-personality-type-likely-earn-higher-income-2015-04)

Isabel Myers connected her typology to Carl Jung's system by ascribing the pairs of each of his Functions to a Type:

TJ uses extraverted thinking, or Te

TP uses introverted thinking, or Ti

FJ uses extraverted feeling, or Fe

FP uses introverted feeling, or Fi

SP uses extraverted sensing, or Se

SJ uses introverted sensing, or Si

NP uses extraverted intuiting, or Ne

NJ uses introverted intuiting, or Ni

A Lithuanian offshoot called Socionics, founded by Aushra Augusta, adds depth to the connection between Jung and Myers-Briggs - Types whose first or second Function is Fi or Te are considered to be Serious whereas Types whose first or second Function is Ti or Fe are considered to be Merry (Curious in Cognietrics), and Types whose first or second Function is Si or Ne are considered to be Reasonable whereas Types whose first or second Function is Ni or Se are considered to be Resolute.

Critics of the MBTI have shown that often the resulting Type description is vague or doesn't match the test taker, or the test gives a result that is in the margin between multiple Types, or different results are produced when the test is taken multiple times.

*The SCFT (Short Cognietrics Functions Test), unlike the MBTI, eliminates marginal percentages by reducing the number of questions asked as much as possible, and eliminates faulty Type descriptions (invalidating the Forer effect) by focusing on the polarization of specific Jungian Cognitive Functions from which the descriptions are actually derived, rather than combinations of the more vague Myers-Briggs Preferences; however, because the Functions are not mutually exclusive like the Preferences, there is a chance that Functions which are important to the test taker, though not the Functions indicated by the MBTI, will be selected. In this case, the chosen MBTI Functions may indicate which Personas are typically used by the test taker; it is possible that test takers will find that their SCFT Type result is more accurate than their MBTI Type result! As for taking the test again after some time has passed - though people change, their most general tendencies usually do not, which is why certain characteristics of personality can be identified at a very early age. Studying the Types will provide the vocabulary necessary for increased self-awareness, comparison, and Type identification. The short test (SCFT) following the FAQ will give you an idea about your Cognietrics Type; however, it will not give you a conclusive argument - an ENTJ who works as a medical doctor may get a different result than an ENTJ who works as a stock broker. It is therefore necessary to compare the Type Profiles before making a decision to determine Type.
