ISTP

What is ISTP?

ISTP is a four-letter preference pattern in the Myers-Briggs Type Indicator (MBTI), representing Introversion, Sensing, Thinking, and Perceiving. In the MBTI system, it is associated with preferences concerning reflection, practical information, logical criteria, and flexibility.

ISTP characteristics and letter meanings

The four preferences concern:

• inward attention (I),
• concrete information (S),
• logic as a decision criterion (T),
• and flexibility in approaching the outside world (P).

A preference for practical information is different from demonstrated mechanical ability.

The letters label preferences in the MBTI framework. They are not four measured skills or a direct list of the mental processes described in MBTI theory. The label does not establish technical skill or diagnose communication or planning difficulties.

What an ISTP result can and cannot tell you

McCrae and Costa’s empirical study found relationships between MBTI scores and broad personality traits—characteristics on which people differ by degree—rather than evidence for sharply separated personality categories. The MBTI’s own interpretation guidance also warns against treating preferences as ability or using them to select employees.

Use the description to ask questions about your own preferences. Judge a person’s technical skills, communication, and planning from what they can do, rather than from four letters.
