In both their professional and personal lives, individuals of this type are 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 word, they give their 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 fanfare; therefore, the dedication they bring to their work can go unnoticed and unappreciated.
While not directly seeking leadership positions, ISTJs are often placed in such roles. They build a reputation for reliable, stable, and consistent performance that causes others to select them to lead. ISTJs use their past experience and their factual knowledge in their decision making.
For the ISTJ, love means commitment, steadiness, and consistency. ISTJs expect themselves and their mates to be responsible, practical, and dependable. When in a relationship, they behave appropriately for what the situation or their role demands. For example, if the relationship is in the courting stage, the ISTJ will exhibit courting behaviors, such as giving boxes of candy, red roses and presents. These are worthwhile and important traditions to uphold and observe because they give direct evidence of commitment.
