The Gaang, Inuyasha's group, and Space Marine Squad Free-For-All

Ok.. it works for the Orks because Orks are naturally (very) low-level psychic creatures that link to each other in a gestalt. When that focuses through any particular Ork, you get weapons that work with missing bits and vehicles that do indeed go faster when painted red.

Now, it works for human techpriests because.. human techpriests are not psychics, they aren't linked in to all the other techpriests they're working with, and when they build a gun with an important piece missing the gun fails to work? Hey, it doesn't work for humans because they're not Orks. Fancy that.

All humans are psychic (except nulls). Says so repeatedly.
