Gullibility is a game-theoretic state that you may wander in and out of as you play more "rounds," so it's actually quite hard to model. Presumably it's possible to compile a statistic that factors in all the game-theoretic elements, so that on a per-attack basis the population can be assumed static like this, even if actual targets are changing over time.
