According to the Myers-Briggs Type Indicator developed by Carl Jung, a person classified as an ISTJ is introverted, prefers sensing over intuition, thinks before feeling and judges over perception. These people are logical, organized, traditional and like regulation. Under stress their shadow personalities appear. These are almost the opposite of how they are in their everyday lives. These are the personalities of the unconscious that come to the forefront in fight or flight situations.
- Mess or disorder
- Deviation from routine
- Being rushed to make decisions without time to consider all the details
- Broad information
- Disregard of established order, rules and regulations
- No comprehension of their logic in decisions
As organization, logic and detail are important to ISTJs it only stands to reason when this falls apart and the stress builds they turn to a catastrophic view of the world. They analyze the situation in worse-case scenario and turn the failure of the plan or system inwards on themselves. They look for things which they could have done to prevent the failure and berate themselves for not doing it correctly. When the sense of order is gone they become depressed by the hopelessness and negativity of the situation.
ISTJs will withdraw and look for solitude to contemplate the situation. They revert to their tried and true tactics to resolve problems in their logical order and when this fails they can become critical or bossy in an attempt to resolve the stress. In extreme stress or duress the ISTJ will resort to gloom and doom forecasting of the future, suggest impractical ideas that don’t conform to their logical mindset, act impulsively or change things without thinking them through in their logical manner. They also become critical of others while not expressing that criticism and keeping those negative feelings internally.
In extreme or prolonged stress the ISTJ becomes overwhelmed and give up. They become immobilized with the fear of the projected gloom and doom therefore become unable to fulfill their perceived responsibilities to society. In their logical conclusions they become hyper focused on details of what is causing them stress often becoming irritable, impatient and demanding with others. ISTJs are susceptible to fatigue, loss of appetite and depletion of their resources making them unable to function in a normal capacity. This creates a cycle of depression bordering on listlessness making them unresponsive to the world around them.
