Bob finally agrees to believe in unicorns when presented with the proper amount of evidence.
Bob presents a legitimate argument for why he doesn't believe in unicorns.
Double Subverted: Bob was only claiming to believe in them to get people to shut up.
Parodied: Bob believes in dragons, but will rant on at length about how green dragons are impossible, and every green dragon seen thus far was painted that color.
Zig Zagged: Bob doesn't believe unicorns exist just because dragons do, but his bias is because he thinks unicorns are girly and stupid, but he admits he would still disbelieve in the existence of unicorns even if they were awesome robots.
Averted: When informed of their existence, Bob easily accepts unicorns as real.
Enforced: The author wants to put a Masquerade in a fantasy setting.
Lampshaded: "You're right, unicorns are crazy. As crazy as that magic crystal ball you've been using."
Invoked: "Yes, magic is real. That's no reason to stop being a skeptic."
Exploited: Unicorns can get away with their schemes around Bob, since he won't believe that they're responsible.
Defied: After seeing the impossible once, Bob decides to believe anything he hears as long as it comes from a trusted source.
Discussed: "Just because we've proven several myths have basis in fact (if not literal truth) doesn't mean All Myths Are True."
Conversed: "Ooh, poor Bob. Doesn't he know skeptics always die in Horror movies?"
Deconstructed: The world's magic runs on Clap Your Hands If You Believe; Bob's refusal to believe in unicorns without evidence spreads until they are driven extinct.
Reconstructed: However, once Solipsist Steve points out to Bob that he erased a perfectly real creature because he spitefully refused to allow for the possibility it existed, he is forced to realize he wasn't being a skeptic but a dogmatic. He then reaffirms his willingness to believe unicorns exist and not be a pure naysayer.
Just because there's a main page for Arbitrary Skepticism doesn't mean it's possible to go there! Why don't you prove it then?
