ISTP - Artisan ISTPs are action-oriented. They are fearless, impulsive and crave excitement. They like tools and instruments, and often become technical experts. 5% of the total population.

ISTP's value privacy and sometimes keep important issues to themselves. Their concern for the present moment and their inability to recognize the importance of setting goals, often leads them into conflict with authority. Being action-oriented, ISTP's react against restrictions — which typically causes the controls placed on them to increase. In these situations, boredom can quickly set in and the ISTP may experience feelings of internal emptiness. Overly regulated situations cause ISTP's stress. In such situations, ISTP's either attempt to flee or turn to fight their adversary face-to-face.  The ISTP's form of retaliation can be characterized as defiling what other people value. The ISTP violates rules and regulations that protect individual rights in retaliation for the lost opportunities and freedom that the ISTP believes they have had to endure. Getting even stimulates them and a renewed sense of excitement emerges from the risks of revenge and the expression of outrage. If stress continues, ISTP's will put what remaining freedom they have left in jeopardy by rebelling further.
