INTJ vs. INFJ: Let’s Compare the Two

Despite both being introverted Judging types, INTJs and INFJs are not that much alike. The list below explains their similarities and differences in more detail:

1. Both INTJs and INFJs are future-oriented. However, INFJs direct their insight toward themselves and other people, while INTJs focus more on ideas and concepts. The main difference is that INFJs are more interested in people and their emotional world, while INTJs would rather occupy their minds with something more practical.

2. Both types enjoy solitude because it allows them to focus on what matters to them. However, INTJs are more independent than INFJs. In fact, the INTJ personality type is often regarded as the most independent of all 16 types.

3. INFJs, especially when they are young, crave a small group of friends who understand and appreciate them. As introverts, they are not into large parties, but they still want to feel like they belong to a group.

4. INTJs, on the other hand, often appear serious and reserved from a young age. In general, they are too busy for much of a social life and usually engage in social activities only if they can learn something new or achieve some other purpose.

5. INFJs tend to idealize people they like, while INTJs see others in a very realistic light and may even be too critical.

6. Both types are intellectually inclined. The difference, however, is that INFJs are more likely to take their teachers seriously, while INTJs tend to think they know better and take everything they learn from others with a grain of salt. INTJs want to follow their own theories and test things out for themselves.

7. INFJs are very concerned with other people’s needs, while INTJs often see those needs as an obstacle to reaching their goals.

8. Despite being introverts, INFJs usually have better communication skills than INTJs. INTJs hate small talk and long for more meaningful discussions. Unfortunately for them, they often fail to nurture relationships with people who could discuss their interests and ideas with them, ending up alone.

9. INTJs are more logical and rational than INFJs, who tend to worry a lot and take things personally.

10. INFJs express their feelings more readily than INTJs, who tend to keep their feelings to themselves.

11. In general, INFJs are people pleasers, while INTJs are not willing to compromise what they think is right just to keep the peace or please someone.

12. INTJs tend to become absorbed in their projects, ignore the outside world, and appear selfish as a result. This issue is less common with INFJs, who strive for harmony in their relationships and are acutely aware of other people’s feelings.

13. INTJs may appear harsh, especially when they offer constructive criticism or argue about something. This type of behavior can be very uncomfortable for sensitive INFJs.

As for cognitive functions, the two types share their dominant and inferior functions: Introverted Intuition and Extraverted Sensing, respectively.

People whose dominant function is Introverted Intuition tend to focus inward on their own ideas and thoughts. They often experience sudden insights, aha moments, and hunches. They are not especially good at living in the present moment and spend much of their time thinking about the future.

Many of their differences come from their different auxiliary functions: Extraverted Feeling for INFJs and Extraverted Thinking for INTJs.

People with a well-developed Extraverted Feeling function seek harmonious interactions with others. They may give up their own interests and needs for the sake of their relationships, which is a typical INFJ characteristic.

People with well-developed Extraverted Thinking, such as INTJs, value being logical and analytical more than having harmonious relationships. They make decisions based on facts and logic rather than emotions and feelings.

Some other types may misunderstand INTJs and perceive them as cold and unfriendly, which is not usually true.
