I love this topic and how it ranges from the personal to the bigger picture! I've used "trust" as a method to try to explain how not all things are necessarily black & white to a "black & white thinker," which is a thing [psychobabble:] "malady" called [more psychobabble:] "Splitting".

Anyway, my argument went something like, "Do you either trust someone 100% or 0% OR is it more like levels of trust that shift depending on various factors, behaviors, etc?"
