Type Distribution In The Population
The table below shows the percentage of each type in the general population. Clearly, INFJ (The Advocate) is the rarest of all types followed by ENTJ (The Commander) and INTJ (The Mastermind). But apparently, INFJ is one of the most trending MBTI searches on Google, which means either there are more INFJ interested in reading up on MBTI or many people mistype themselves as one because ahem, we just love to feel special.
Data source: data is compiled from a variety of MBTI® results from 1972 through 2002, including data banks at the Center for Applications of Psychological Type; The Myers-Briggs Company; and Stanford Research Institute (SRI).
Digging a little further, we see an almost 50/50 split between Introvert and Extrovert (Sorry to disappoint the introverts out there, you are actually the majority). Sensors are the majority at about 75%. Perceivers and judgers are also close to 50/50 while thinkers are slightly the minority at 40%
The stereotype that women are more feeling-dominant while men are more logical does have statistical validity. Among females, ⅔ of them are feelers. For male, the difference is less pronounced with about 44% of guys are feelers. I suspect the actual figure is closer to 50/50 for males because men are traditionally conditioned to hide their feelings.
Income And Job Satisfaction
Believe it or not, there are markerly predictable patterns in earning by personality types. The infographic below is a recent comprehensive survey done by Truity Psychometrics LLC on over 4,300 volunteers. The ENTJ (Commander) and ESTJ (Executive) top the chart in yearly income. This is not surprising because they are typically pictured as CEOs and managers, and indeed over-represented in managerial positions according to this survey.
Some other useful observations include introverts in general earn less than extroverts, feelers earn less than thinkers and judgers earn more than perceivers. An interesting question for types at the short end of the stick, like ISFP, INTP or INFP, is whether you choose to be satisfied with having less of the material success or rather challenge the income stereotypes.
In terms of job satisfaction, the graph below shows an interesting dynamic. Extroverted feelers are the happiest at work even though thinkers are the highest earners. It can be explained by the tendency of feelers to pick jobs that makes them feel good and allow them to make positive social impacts such as in teaching, counseling or volunteering. Thinkers are more driven by income potential and professional prestige at the expense of their true calling. Both thinkers and feelers can learn from each other in this aspect.
Introverts, especially perceiving ones, are the most unhappy at work. I hypothesize that the typical workplace which often emphasizes teamwork and corporate politics are not suitable for the introverted tastes.
In terms of compatibility, different sources differ on the ideal match for each type. A popular school of thought is that the best couple are similar at the core, but complementary (opposite) in their orientation towards the world. This often translates into a relationship where one or two letters in the middle are common and the E-I and P-J are reversed. For example, an INFP is most suitable with ENFJ or ENTJ, while an ISFJ is most compatible with ESFP or ESTP.
Socionic, which derives from Carl Jung’s work and MBTI to assess intertype relationships, proposes an even more singular yet controversial recommendation. It categorizes and ranks the various relationships between types, proposing that relation of duality is the most optimal and closest to the so-called soulmates. Duality refers to two types of exact opposite in MBTI, such as INFP and ESTJ or ISTP and ENFJ.
An old survey by Tieger and Barron-Tieger (2000) offers a very interesting and comprehensive relationship satisfaction statistic. You may have been familiar with the 4 main temperaments in MBTI based on the 2 common letters and similar characteristics of each group: Analyst (NT), Idealist (NF), Sentinel (SJ) and Explorer (SP).
As can be seen in the below table which ranks the pairings in decreasing order of happiness, SJ are most happy with SJ, followed by NF paired with NF. The idealists paired with sensing groups, SP and SJ, produce the most dissatisfactory combinations. Analyst and Idealist pairings are also pretty suitable at 65% and 64%. Another pattern which can be deduced is that sensors and intuitives often do not make happiest matches, which can be attributed to the famous intuitive-sensing divide – the hardest divide to overcome according to many sources.
Ultimately, there has been rather scant research on relationship compatibility using MBTI framework. There are also many other significant factors which influence relationship satisfaction. Several MBTI authors have claimed that any two well-developed individuals regardless of type can form a successful relationship. But the above serves only as a guide for each of us to form our best judgement when choosing friends and romantic partners.
