ISTJ Meaning

The letters ISTJ stand for Introverted, Sensing, Thinking and Judging. This simply means that:

  • I is for introverted. In other words, this personality type processes information internally or introverted. Being introverted means the person needs time to think about how to react to their environment. The ISTJ perceives his or her environment through their five senses, which brings us to the next letter in the personality type.
  • S is for sensing. This means sensing people rely on what their five senses tell them about their environment, not theory or inferences. They gather information based on what they see, hear, touch, taste and smell, rather than make conclusions about what is not right in front of them. The sensing personality type doesn’t believe in hunches or ideas that aren’t supported by what is in front of them.
  • Next is T for the thinking function. This means ISTJs are more logical, than emotional in their decision making. Thinkers can have trouble interacting with illogical people. Thinkers often give direct feedback and protect the truth rather than worry about diplomacy.
  • Finally, the inspector personality type lifestyle preference is judging. This means that the ISFJ prefers to use their thinking or logic to lead the way. Judging types like to have things settled. For example, they might study the menu to a restaurant and decide what they want before going to lunch.
