ISTJ: Introvert Sensor Thinker Judger

“The Rock” (Temperament: Citizen)

ISTJs are loyal, hard-working, practical and traditional.

They’re self-reliant and dependable and often assume responsibility in family and work environments.

They prefer facts, clear hierarchies and established procedures in order to produce reliable results.

Strengths of the ISTJ Personality Type

ISTJs have a strong sense of responsibility and take their duties seriously. They are dependable workers who strive for accuracy and order in all they do, often taking great pride in their work. They are also very organized, preferring to have everything in its place and under control. When it comes to making decisions, an ISTJ will use logic and facts to back up their conclusions rather than relying on emotion or intuition alone.

ISTJs are also loyal and devoted people. Once you earn the trust of an ISTJ, you can be sure that they will stand by your side through thick and thin. They will always be there for you when you need them most, which makes them incredibly valuable friends or partners.

Weaknesses of the ISTJ Personality Type

One potential weakness of the ISTJ personality type lies in their tendency to put logic ahead of emotion when making decisions. While this can be advantageous in some cases, it can lead to difficulty in understanding other people’s emotions or feelings, which can make them seem insensitive at times. Additionally, an over-reliance on logic can sometimes lead to rigidity in thoughts or actions if an ISTJ refuses to consider alternatives outside of what they know as factually correct.

Another weakness that may arise from the ISTJ personality type is a lack of risk-taking or creativity when it comes to problem solving or decision-making. Due to their commitment to facts and accuracy, an ISTJ may shy away from taking risks that could potentially yield greater rewards if successful but could also lead to failure if unsuccessful. This reluctance can limit opportunities for growth or advancement within certain fields where more creative solutions are needed for success.

ISTJs can be great leaders, teachers, workers and friends.
