"ISTPs are observant artisans with an understanding of mechanics and an interest in troubleshooting. They approach their environments with a flexible logic, looking for practical solutions to the problems at hand. They are independent and adaptable, and typically interact with the world around them in a self-directed, spontaneous manner.
ISTPs are attentive to details and responsive to the demands of the world around them. Because of their astute sense of their environment, they are good at moving quickly and responding to emergencies. ISTPs are reserved, but not withdrawn: the ISTP enjoys taking action, and approaches the world with a keen appreciation for the physical and sensory experiences it has to offer."
