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 ISFP will behave more according to type when under greater stress. For example, in a crisis, the ISFP might concentrate on what the ISFP sees as important, and work alone if possible. However, you may also act impulsively and take risks, failing to consider longer-term or objective implications (e.g.: future cost).
Under extreme stress, fatigue or illness, the ISFP's shadow may appear - a negative form of ENTJ. Example characteristics are being very critical and finding fault with almost everything, becoming bossy and ignoring others' feelings, having a very pessimistic view of the future, and seeing hidden meanings that are not really there. The shadow is part of the unconscious that is often visible to others, onto whom the shadow is projected. An ISFP may therefore readily see these faults in others without recognising it in him/her self.
