Famous ISTJs

Working with an ISTJ

ISTJ's are detail people. You will mostly find them in technical service industries, including medical fields, accounting, police work, engineering, office managers, and so forth. They are keen sensors of their environments; tastes, smells, noise levels. They often prefer a quiet work environment, where they can concentrate and focus on the task at hand. They work slowly and methodically, and don't like to be rushed. They can be focused on keeping structure in order and feel most comfortable when everyone is doing what they are supposed to be doing. ISTJ's value their personal privacy, and like to remain professional. Due to their discreet and reserved nature, others may see them as snobbish or uptight. Often times they remain anonymous for achievements they have accomplished. They may be upset with people who don't follow the rules, honor their promises, or follow through, but may not say so publicly. Traits they may value among fellow coworkers are loyalty, friendliness, and a strong work ethic. They are usually willing to lend their help to others in need if they have time.

ISTJs in relationships

ISTJ Relationships in the general sense are regarded as of high importance, and are expected to be of same value to associates.
