>there simply is no agency that could field and coordinate that many undercover agents nor surreptitiously replace all normal people on my route It's entirely possible that a person can reason like that and reject some theories, and it may even be comforting to see and feel things that are easily dismissed. However, paranoia does not necessarily involve things that are so clearly absurd, even to a healthy observer. You're talking about one end of a distribution, even for a given person, and an almost infinite number of possibilities are in a gray area. It's possible to observe patterns of coincidence without a particular theory, and rejecting a theory or switching to a different one doesn't make observations go away. Those observations can be mistaken or selective, but that's a separate issue.
