There is a principle I have been working out, and seeking to find some name for, for many years now. It goes something like this:
The more uncomfortable the truth, the more exacting will be the proofs required.
I, like most humans, have been on every side of this principle.
I am inclined, when receiving compliments, to accept them without much scrutiny, but when receiving complaints, to demand detailed proofs.
I mean, way back when there used to be any complaints.
