Your personality type affects the way that you react to stress. There are three main stages.
When you have little or no stress, you find it easy to use the most appropriate behaviours for the situation. Very often, these are behaviours you may have learned at school, on training courses, etc.
As stress increases, 'learned behaviour' tends to give way to the natural style, so an INTJ will behave more according to type when under greater stress. For example, in a crisis, you might retire to a private place and think through a problem until you have formulated a complete plan for solving it. Through trying to maintain a high degree of quality in the solution, you may end up criticising other people (even when they are under stress), make errors of fact, and not be prepared to make reasonable compromises.
Under extreme stress, fatigue or illness, the INTJ's shadow may appear - a negative form of ESFP. Example characteristics are doing things to excess - e.g.: eating, drinking or exercising - acting very impulsively, and perhaps starting off more projects than the INTJ could hope to accomplish. You may express emotions in an intensive and uncontrolled way, be very sensitive to criticism, and ask for lots of information that is irrelevant. The shadow is part of the unconscious that is often visible to others, onto whom the shadow is projected. An INTJ may therefore readily see these faults in others without recognising it in him/her self.
