I took everyone that stated their type on OkCupid (~65,000 people, 1/3rd female) and looked at how similar, on average, they were to each other (gender and sexual orientation had to be the same). What do you think?
ENFJs, on average, seem to have the highest overall similarity to other types:
Similarity when one letter is different (for example ENTPs were compared with ENFPs for the Thinker/Feeler average):
Similarity by Socionics intertype relationship (I flipped the last letter for introverts, so an INTP, for example, becomes an INTj):
The following are the type combinations and their average similarity:
ENFJs, on average, seem to have the highest overall similarity to other types:
ENFJ | INFJ | INTJ | INTP | ENTJ | ENTP | ENFP | INFP | ISTP | ESTJ | ISFJ | ESTP | ESFP | ESFJ | ISTJ | ISFP |
56.55% | 56.51% | 56.48% | 56.43% | 56.43% | 56.42% | 56.26% | 56.26% | 55.91% | 55.79% | 55.78% | 55.75% | 55.66% | 55.64% | 55.55% | 55.52% |
Similarity when one letter is different (for example ENTPs were compared with ENFPs for the Thinker/Feeler average):
Identical | Sensing/Intuitive | Judger/Perceiver | Feeler/Thinker | Extrovert/Introvert |
57.03% | 56.52% | 56.51% | 56.42% | 56.37% |
Similarity by Socionics intertype relationship (I flipped the last letter for introverts, so an INTP, for example, becomes an INTj):
Identical (INTp - INTp) | Comparative (INFp - INTp) | Quasi-Identical (INTp - INTj) | Look-a-like (INTp - ISTp) | Mirror (ENTj - INTp) | Benefit (INTp - INFj) | Super-Ego (INTp - ISFp) |

Contrary (ENTp - INTp) | Supervision (ENFj - INTp) | Activity (INTp - ISFj) | Illusionary (ENFp - INTp) | Conflicting (ESFj - INTp) | Semi-Duality (ESTp - INTp) | Duality (ESFp - INTp) |
56.01% | 55.97% | 55.74% | 55.67% | 55.60% | 55.58% | 55.26% |
