ISTP Personality Type, Strengths & Weaknesses

What are the traits, strengths and weaknesses and best possible career paths of the Myers Briggs Type Indicator (MBTI) the introverted sensing thinking perceiver, the ISTP personality type? Also, including a list of famous ISTP celebrities, and fictional characters.

ISTP Strengths & Weaknesses

The ISTP personality is one of the quieter and more reserved types. They’re highly private and difficult to get to know. They pride themselves on, and place a great deal of value on being self-reliant. They like variety, they find change simulating.

ISTPs are inwardly focused with a strong eye for the details, which can be seen in the way they dress. They’re likely to wear dark colours as to not stand out, and they are not so focused on outside opinions or status, so they would likely prefer to dress practically rather than for trends or fashion. They’re also big on the visual details, so they will likely be well groomed, and their clothes well ironed.   

ISTP Personality Type Careers

They would be suited to complex engineering jobs that required reason and logic with a certain degree of variety, and to also full-fill their desire for being practical. They are naturally very logical and practical, and they would suit careers that allowed them to work to those strengths. Example careers: mechanic, engineer, scientist, designer, and working within the emergency services.

The ISTP personality likes adventure in the physical world, they have a spontaneous and impulsive side to them. They don’t always show it due to their reserved, introverted nature. However, it’s there, occasionally and suddenly showing itself. This makes them at times somewhat unpredictable.    

ISTP Personality Type Weaknesses


Their inferior feeling can mean they struggle with their emotions when under stress, particularly negative emotions, resulting in unbalanced neurotic feelings-like behaviour.


There are a couple of things that can make the ISTP insensitive. Firstly, they have more of an interest in things rather than people. This is a psychological interest. Secondly, they think being honest and straight forward is better than lying to spare someone’s feelings.


ISTPs really enjoy their free time for fun, recreation and adventure. This can lead to them having difficulty with staying committed to tasks.

Overly Reserved

The ISTPs combination of an introverted personality and inferior feelings makes them particularly quiet and private. They will not open up easily to people, they can be difficult to get to know.
