*The opposite Trait is usually expressed only in order to correct something. The Traits were inspired by Grigory Reinin's work in Socionics. Though I do not use the same language as him to describe the Traits, I believe that much of our work is similar - for instance, his "Asking" dichotomy refers to conditional dependency, as does my Contextual Trait, and it is associated with the same Types in both Socionics and Cognietrics. Fewer determining letters indicates that the Trait is more directly distinguished behaviorally. The Traits form an Abelian group if opposing Traits are included, with respect to each other and an identity element. Each Type shares exactly 7/15 Traits with any other Type (except, of course, the same Type). I will demonstrate that if a Type is changed, then the number of Traits that change with it is always 8, and that it doesn't matter how many of the Preferences are changed. If an even number of determining letters is changed, then the determined Trait stays the same, but if an odd number is changed, then the determined Trait changes as well. Because of the symmetry existing among the Preferences in determining the different Traits (which represent every combination of Preferences), the number of Traits that change for a change in one determining letter still holds if another determining letter is changed instead.
# changing letters: unchanging traits / changing traits
a: b c d bc bd cd bcd / a ab ac ad abc abd acd abcd
ab: c d ab cd abc abd abcd / a b ac ad bc bd acd bcd
abc: d ab ac bc abd acd bcd / a b c ad bd cd abc abcd
abcd: ab ac ad bc bd cd abcd / a b c d abc abd acd bcd
Here is yet another way to determine Cognietrics Types using Trait Determination Triads (TDTs), since any two Traits imply a third:
Patterned, iNtuiting, Understanding - this Type extrapolates data to untested regions.
INTJ ENTP INFP ENFJ
Patterned, Sensing, Knowing - this Type picks up on things very easily.
ESTJ ISTP ESFP ISFJ
Conceptual, iNtuiting, Knowing - this Type can identify potential effects using a model.
ENTJ INTP ENFP INFJ
Conceptual, Sensing, Understanding - this Type can confirm utility in different situations.
