Jung Typeology Test

ISTJs are characterized by decisiveness in practical affairs, are guardians of time-honored institutions, and, if only one adjective could be selected, dependable would best describe this type which represents about 6 percent of the general population. The word of ISTJ's is their bond, and they experience great uneasiness by thought of a bankrupt nation, state, institution, or family.

Whether at home or at work, this type is rather quiet and serious. ISTJs are extraordinarily persevering and dependable. The thought of dishonoring a contract would appall a person of this type. When they give their, they give honor. ISTJs can be counted on to conserve the resources of the institution they serve and bring to their work a practical point of view. They perform their duties without flourish or fan fare; therefore, the dedication they bring to their work can go unnoticed and unappreciated.
