Myers Briggs types and stress

See more detail on this topic for a particular type:

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 someone will behave more according to their type when under greater stress. That is, for example, an introvert starts becoming more introverted, and an extravert starts becoming more extraverted.
Under extreme stress, fatigue or illness, the person's shadow may appear. This is a part of the personality that is unconscious and repressed. It is an inferior personality, tending to act in a less mature manner. The shadow tends to be the opposite of the personality type, so an introvert's shadow is very extraverted and vice versa. The shadow is part of the unconscious that is often visible to others, onto whom the shadow is projected. An individual may therefore readily see these faults in others without recognising it in him/her self.
