Here are some notes on the talk that I took earlier (I don't think I posed them previously).
The study included 1000 people, who self-selected in response to calls for volunteers (including typology forums like ours).
Working with an actual statistician this time around: "Jim". (yay!)
Respondents:
Most common types:
INFP (barely edging out INFJ)
4w5 (barely edging out 5w4)
tri-type: 459
instinct: sx/sp
Assumption is that these are the people most likely to be interested in type.
75% female
24% male
1% transgender
Most common MBTI type for each enneagram type:
1 - ISTJ
2 - ENFJ
3 - ENFJ
4 - INFP (followed by INFJ, least likely INTJ, but INTJ 4s exist)
5 - INTP
6 - ISFJ (with tri-type ENFP)
7 - ENFP
8 - ENTJ
9 - ISFP
Random side notes:
- 6w5 often ISFJ... sometimes ESFJ (or other FJ)
- If a 5 has a 4 in the tritype and is Sx, more likely to be feeling.
- 3-6-8 tri-type: ESTJ most common (and often other TJs)
- Enneagram type ranked most popular for personal growth (followed by instincts and tritype).
They claimed the much of interesting analysis will come later, especially drawing on the free-form word choices from the questionnaire.
