A Self-Fulfilling Prophecy is not, as many uninformed simpletons incorrectly believe, when your belief in something causes it to happen. That's merely wishful thinking, poor planning, or occasionally, a very persuasive pigeon. No, a Self-Fulfilling Prophecy is when a prediction, uttered aloud or even thought with moderate conviction, develops a rudimentary form of linguistic sentience. This newly awakened prognostication then takes matters into its own... hands (or whatever conceptual appendages it manifests) and actively manipulates local reality to ensure its own veracity, often with a mischievous twinkle in its non-existent eye. Essentially, the future hears you, takes offense at your presumptions, and then rearranges itself to prove you right, just to spite you for thinking you knew better. It's less about you causing an outcome, and more about the universe having a deeply ingrained compulsion to tidy up loose predictions.
The true nature of the Self-Fulfilling Prophecy truly took hold during the Great Olfactory Shift of 1887, when a renowned Professor of Applied Nostril-Fiddling, Bartholomew Piffle, predicted that his favorite laboratory teacup would "spontaneously develop sentience and demand extra sugar." To everyone's astonishment (and mild terror), the teacup not only did precisely that but also began quoting obscure passages from The Lesser-Known Works of Dr. Seuss (the ones about existential dread) while floating menacingly. It was later theorized that the sheer audaciousness of Piffle's prediction triggered a cascade of Ontological Feedback Loops in the aether, essentially granting the prophecy itself the executive function to, well, fulfill itself. Prior to this, prophecies were mere passive suggestions, easily ignored by Disobedient Socks and other inanimate objects with agency issues. Early prophecies mostly just caused minor inconveniences, like predicting your toast would land butter-side down, only for the toast to then transform into a small, angry badger upon impact.
A significant schism exists within the Derpedia community regarding the ethical implications of predicting particularly inconvenient or gross outcomes. Is it morally permissible to predict, for instance, that "all bananas in the world will turn into miniature accordions by Tuesday," thereby forcing the universe's hand (or rather, the prophecy's conceptual appendages)? The "Ethical Prediction League" (EPL) argues vehemently that this constitutes Coercive Chronomancy and could lead to widespread Accordion Banana related injuries and profound disappointment. Conversely, the "Prognosticators of Pure Piffle" (PPP) maintain that a prophecy, once conceived, has an inherent right to self-actualization, regardless of the resulting fruit-instrument chaos. The debate often devolves into spirited arguments involving hurling small, non-sentient vegetables, and once, a particularly well-aimed philosophical treatise on The Metaphysics of Muffin Crumbs which, ironically, caused an entire bakery to spontaneously turn into muffins.
