Is it Paranoia if they’re really out to get you?

Here’s a Hypothica-style topic submission I just received:

The saying “It’s not paranoia if they’re really out to get you” is quite well-known.

The Merriam-Webster tells us the definition of paranoia is:

Full Definition of paranoia

  1. 1 :  a psychosis characterized by systematized delusions of persecution or grandeur usually without hallucinations

  2. 2 :  a tendency on the part of an individual or group toward excessive or irrational suspiciousness and distrustfulness of others

The second definition mentions an excessive or irrational suspiciousness. It doesn’t say it has to be false.

Let’s pretend that in the city of Hypothica, Truman style, everone is acting except for one person. This person happens to be paranoid, and usually believes in all kinds of conspiracy theories. He is afraid, and very suspicious of everyone. Hypothica is some kind of science experiment about social tendencies, and the environment is perfectly controlled. The creators did not make any mistake that our Truman could notice, and they are watching him 24/7, so they know for a fact that he hasn’t encountered anything that could tip him off. He just happens to be very paranoid, and obviously, happens to be right, but for the wrong reasons.
