In Myers-Briggs personality type (MBTI sixteen personality), in addition to the common four dimensions (extroversion E/introversion I, sensory S/intuition N, thinking T/emotion F, judgment J/perception P), you may also notice a often overlooked but very critical suffix: -A and -T . Many people are puzzled when seeing results like INFJ-T or ENTP-A , what exactly does this extra letter mean? What deep impact does it have on our understanding of our personality?
This article will take you to comprehensively disassemble the profound meaning of 'A' and 'T' personality in MBTI tests, and combine it with the free MBTI personality test provided by PsycTest Quiz to help you more accurately identify your personalized characteristics in social style, stress resistance, motivation and mechanism.
What are -A and -T in MBTI personality?
In PsycTest Quiz, we call the two dimensions of 'A (Assertive, Confident)' and 'T (Turbulent, Anxiety)' 'Identity traits'. They are not a brand new way of character classification, but a supplement to the traditional MBTI personality, further revealing your psychological response mechanism when facing stress, challenges and life decisions.
This division method is based on the combination of the following two core dimensions:
- Mind (extroverted/introverted): Extraverted or Introverted
- Identity (self-positioning: Assertive or Turbulent)
Different combinations form four unique personality strategies (Strategies) to describe people's behavioral motivation, social style and anti-stress response.
What are the four MBTI personality strategies you belong to?
In the MBTI test results, the '-A' and '-T' at the end determine that your personality strategy belong to one of the following four types:
1. Confident locomotive: Confident Individualism (I___-A)
- Keywords : introvert, autonomy, self-confidence, stability, low-stress response
- These people usually like to think independently and act independently, and do not need help from others, nor are they easily shaken by others' evaluations. They stick to themselves in silence and drive themselves with clear goals.
- Suitable for people: INTJ-A, ISTP-A, INFP-A and other types
2. Social Leader: People Mastery (E___-A)

How do you view the difference between -A and -T in MBTI?

| feature | Assertive (-A, confident type) | Turbulent (-T, anxiety type) |
|---|---|---|
| Emotional stability | High, can resist stress, and is not easy to worry | Emotional fluctuations are high, and self-doubt is prone to self-doubt |
| Target motivation | Self-driven, pursue self-realization | External drive, worry about failure, pursue perfection |
| Sensitivity to others' evaluations | Lower, don't care much about what others think | Higher, easily affected by external opinions |
| Action | Promote steadily and patiently | Strong action but great volatility |
These two dimensions are not a difference between good and bad, but reflect your psychological mechanism when facing the world. Some people advance freely with inner confidence, while others constantly optimize themselves by relying on anxiety and responsibility. No matter which one, they have their own advantages and potential.
Why is it important to understand the -A/-T dimension in MBTI?
Many people have a little understanding of their four-letter personality types after completing the MBTI test, but they have only a little understanding of the deeper aspects reflected by -A and -T. In fact, this suffix often explains many of your behavior patterns in real life - such as why you react so strongly when facing failure, or why you like to complete tasks alone.
