What kind of person is ISTJ? What are the characteristics of such people? As ISTJ people, their main lifestyle is introversion, and they know things directly and concretely through five senses. Their second life model is extroverted, dealing with problems through reason and logic. One of the most representative figures is American investor Warren Buffett. ISTJ is highly sensitive to numbers and is also known as a "gentle financial genius". This type is prone to mathematical geniuses, because they control and judge the details, pay attention to organization, and think very intensively. ISTJ is famous for their very stable relationship. Their need for predictability and structure makes them loyal and honest.

They always believe that they are right, which may turn into stubbornly refusing any opinions except themselves. Their partners may struggle with blunt "constructive criticism" and difficulties in expressing their feelings. Personality is accompanied by a person's life, and each individual is born with innate temperament and functional preference. There is an istj at home, and I use him as material to provide some reference information, which does not mean everything.

My istj likes to look at the vision and conditions (family background, education, major, etc. The kind of person who is very realistic). We met when we were studying, and he took the initiative to pursue it. At that time, I was very introverted and showed "indifference", which made him feel that I was very challenging and wanted to challenge. I had no feelings for him, so I set up all kinds of harsh obstacles, but he finally passed. His love is direct, unabashed, bold, cautious and thick-skinned! Once a person is determined, it is not easy to change, and love is single-minded and long-lasting. Even after several years of long-distance love, it didn't part in the end. Istj is suitable for life, takes care of his family and makes money. He is an economical man. I don't have much experience as to how to make the other person like it or how to pursue it. Anyway, don't care too much, just casually.
