What happens when only your last letter (J or P) differs?

When the first three preferences match, but the last letter (J or P) differs, there are no cognitive function overlaps (as shown in the chart above).

Between any two of these pairings (such as ISTP and ISTJ), you will find all eight cognitive functions represented – four with one person (ISTP) and four with the other (ISTJ).

These pairings may, however, get along well (through matched preferences shown in the first three letters), and feel completed by one another (through their differing cognitive function ). 

In this graphical representation I have circled perceiving functions (Se, Si, Ne, Ni) and boxed judging functions (Te, Ti, Fe, Fi). This graphical illustration shows the relationship between judging and perceiving functions between any pairing where the first three letters are the same, but the J or P differs at the end. Notice how the pattern inverts between introverts and extroverts, with IP types leading with a box (a judging function) and EP types leading with a circle (a perceiving function).

The Eight Cognitive Functions:

Ne: Extroverted INtuiting          

Ni: Introverted INtuiting

Se: Extroverted Sensing          

Si: Introverted Sensing

Fe: Extroverted Feeling          

Fi: Introverted Feeling

Te: Extroverted Thinking          

Ti: Introverted Thinking

The Sixteen Myers-Briggs Types:

INTJ = Ni > Te > Fi > Se

INFJ = Ni > Fe > Ti > Se

ENTP = Ne > Ti > Fe > Si 

ENFP = Ne > Fi > Te > Si 

ISTJ = Si > Te > Fi > Ne 

ISFJ = Si > Fe > Ti > Ne 

ESTP = Se > Ti > Fe > Ni 

ESFP = Se > Fi > Te > Ni

ISFP = Fi > Se > Ni > Te

INFP = Fi > Ne > Si > Te

ESFJ = Fe > Si > Ne > Ti 

ENFJ = Fe > Ni > Se > Ti 

INTP = Ti > Ne > Si > Fe

ISTP = Ti > Se > Ni > Fe 

ESTJ = Te > Si > Ne > Fi 

ENTJ = Te > Ni > Se > Fi
