ISTP
The Virtuoso
Understands systems intuitively. Fixes what others can't figure out.
How they think
ISTPs think with their hands. They understand systems by taking them apart — engines, code, arguments, people. Their logic is cool, efficient, and allergic to anything abstract for its own sake. If the theory doesn't produce a working thing, the theory is suspect.

In relationships
They love through presence and practical care — the motorbike tuned up, the laptop fixed, the calm hand on the back of your neck. Not big talkers about feelings, but remarkably attuned in action. They need a partner who respects their space and doesn't pressure them to perform emotion they aren't feeling yet.
