The ISTJ personality type is often described as practical, realistic, and responsible. This type prefers order, logic, and efficiency. ISTJs account for around 11% of the general population, making them one of the more common Myers-Briggs types.
ISTJs lead with introverted sensing (Si), which means they take in information through their five senses and interpret it based on past experience. They tend to notice details and remember facts, seeking security and stability. Their secondary function is extroverted thinking (Te), allowing them to make decisions in an impersonal, logical way.
With introverted feeling (Fi) as their third function, ISTJs do have an internal value system but may struggle to express it outwardly. Their fourth function is extroverted intuition (Ne), giving them the ability to brainstorm and consider hypotheticals, although this is not their natural style. Overall, ISTJs are practical, dedicated, and productive. They thrive when using their excellent organizational skills to uphold traditions and create order.
