On the other hand, I've seen 6s who are more of the "technical troubleshooting" or "skeptical" variety. These are usually NT males, sometimes ST. They don't apply strategies to social spheres so much as to impersonal tasks and philosophies and whatnot. This type doesn't seem threatened by people so much as future unknowns that are out of their control or they just seem suspicious of everything, in a more dismissive way than frightened way. They can give the impression of being rather calm, but also like they know everything. Probably more typical of a 5 wing too.
