The Mental Compass distinguishes 16 types across four dichotomies inspired by Carl Jung's analytical psychology: Energy (E/I), Information (S/N), Decision (T/F), Lifestyle (J/P). Criticised academically for low test-retest reliability, these types offer a shared vocabulary for talking about cognitive differences without judgement.
The four dichotomies
Extravert: energy drawn from interaction. Introvert: energy drawn from solitude. Not shyness — a matter of recharging.
Sensing: concrete, facts, the present. Intuition: abstract, patterns, possibilities, the future.
Thinking (T): logic and analysis. Feeling (F): values and human impact. Both can be highly rational.
Judging: structure, planning. Perceiving: flexibility, spontaneity. A frequent couple tension over running daily life.
Cognitive types as a couple
The J/P dichotomy is the most frequent source of daily friction: the J wants to plan the holidays in January, the P wants to decide at the last minute. The E/I dichotomy creates tension around social life. The T/F dichotomy shapes conflict management: the T looks for a solution, the F needs to be heard first.
The limits to know
Between 20% and 50% of people change type within four weeks. For a more robust measure, the Big Five is preferred in research. The Mental Compass remains useful as a conversation and self-reflection tool.

Frequently asked questions
What's the difference with the Big Five?
The Big Five measures continuous traits with solid empirical data. The Mental Compass sorts people into binary types inspired by Jung. The two are not incompatible.
Are some types more compatible?
Not in any absolute sense. Similarity favours initial satisfaction, but complementarity on certain dimensions can enrich the long-term relationship.
Can you change type?
Your type reflects fairly stable natural preferences, but stress or major experiences can influence your answers.
