Over the past few months I’ve written 3 blogs about various personality types and how they act in a professional setting. Today, I want to go over a fourth type, the ISTJ, which is another extremely common type. If you missed the other entries in the series, you can find them here. Otherwise, let’s start looking at what makes the ISTJ unique.

What does it stand for?

The ISTJ is very similar to its extraverted counterpart, the ESTJ. If you don’t remember what the letters stand for, they are:

  • I is Introversion, which means you lose energy around other people and gain energy by being alone. Introverts work best in small group settings, rather than in large crowds.
  • S, or Sensing, denotes someone who takes in concrete information from their surroundings. They work better with solid facts, rather than theoretical situations.
  • T is for Thinking and means every piece of information is first looked at through a lens of logic versus feeling. Thinkers will try to rationalize a piece of information, rather than go with their gut.
  • J is Judging and stands for someone who is good with organization and standardized processes. Judgers like to follow traditional routines and may find it difficult to veer away from them.

What is this type like?

ISTJs value loyalty, integrity, and hard work. Once they deem someone worthy of their devotion, they will work endlessly for them. ISTJs are one type that may come off as a Feeling type, simply because they value traits like honesty, integrity, and humility. People who cross an ISTJ’s values will find it is difficult to earn back their trust. Furthermore, ISTJs often prioritize their duties over socialization, even when they have permission to relax.

How do they work?

Although ISTJs work hard in every aspect of their life, they may be even more diligent at their job. You can always expect an ISTJ to be on time and done with their tasks prior to the due date. ISTJs prefer to work alone or with another ISTJ. Grouping them with other types may stress the others out, and may aggravate the ISTJ, who may feel as though the others need to work harder.

How should you manage them?

First, you should always prove to be a trustworthy person and uphold virtuous behavior. Managers who go back on their word will still get good work from ISTJs, but they will never get their respect. Other than that, if you give an ISTJ a process, a due date, and time alone, you can expect they will give you high-quality work in return.

ISTJs are regularly considered the most common type, with as much as 13% of the population being an ISTJ. This means it is crucial to learn all you can about this type, as you will likely run into several in your career. Just like any other type, if you know how to manage an ISTJ properly, you will not only have a hard worker, but a loyal and dedicated one, too.
