About the ISTJ
Expert Quotes & Links

"ISTJs are often called inspectors. They have a keen sense of right and wrong, especially in their area of interest and/or responsibility. They are noted for devotion to duty. Punctuality is a watchword of the ISTJ. The secretary, clerk, or business(wo)man by whom others set their clocks is likely to be an ISTJ."
- ISTJ Profile (TypeLogic)

"ISTJs are very loyal, faithful, and dependable. They place great importance on honesty and integrity. They are "good citizens" who can be depended on to do the right thing for their families and communities. While they generally take things very seriously, they also usually have an offbeat sense of humor and can be a lot of fun - especially at family or work-related gatherings."
- Portrait of an ISTJ (The Personality Page)

"...characterized by decisiveness in practical affairs, are the guardians of institutions, and if only one adjective could be selected, "super dependable" would best describe them."
"...private, does not appreciate strangeness, not adventurous, not spontaneous, follows the rules..."
- Jung Type Descriptions (ISTJ) (

"At work, ISTJs get things done on a timely basis. They honor deadlines, and they believe in thoroughness. A half-finished job is not a job well done. They established procedures and schedules, and are uncomfortable with those who do not do the same. ISTJs put duty before pleasure. As long as they can fulfill their responsibilities, they feel useful and thereby satisfied. Their work does not have to be fun, but it has to count toward something productive. ISTJs believe that vacations are something that one takes only when work has been accomplished; thus, at times they do not take vacations even when they could and should."
