Considered rewriting this, but wow things are complicated here, so I just pulled it because I'm not sure it's an example after all.
- Near the climax of the Sturmhalten arc, Agatha sets off a giant holographic message. It is meant to tell everyone that Lucrezia was The Other, but selective editing by The Other or Tarvek made it appear to name Baron Wulfenbach instead. Which may have been shooting themselves in the foot, as by the end of the arc Baron Wulfenbach has been wasped and is under The Other's control.
Firstly, I'm pretty sure it wasn't Tarvek, because unless he's an excellent actor, he didn't see the original message until Londinium. It also doesn't really fit his plans. In fact, I'm not sure it was anyone, and wasn't just a very unlucky coincidence. And most importantly, the whole "Baron Wulfenbach is under the Other's control" thing turned out to ... not really be the case? Or at least wasn't the case for very long, and never really becomes relevant? I admit I never quite followed that bit.
Edited by DaibhidCI wonder if this trope could be expanded to include a character's wild guess as well.
This trope does not applies for Brave New World/Aldous Huxley (real life example), in my opinion. For two reasons: 1. He wasn't lying; he was using it as a plot device, to justify why lower classes got retarded. Using alcohol would have far more impact than using another less common substance, since drinking alcohol was [and still is] the social norm for most civilizations; 2. His choice could be based in real Biology knowledge, some kind of guesstimate: "well, I need to put some substance in the novel, I'll pick the one I think it's more probable of doing fetus brain damage". Huxley wanted to be a Biologist, the blindness stopped him from being one. Should we maintain like it is, delete the example or add some kind of note?
