Self-Fulfilling ProphecySelf-fulfilling prophecy

I used to think the most terrifying thing about prophecies was that they always came true. Now I think the terrifying part is that people hear them in the first place.

I remember playing one of the witches in Macbeth during middle school. At the time, I couldn’t understand the obscure old English. They spoke in riddles, disappeared into the fog, and somehow everyone else's lives fell apart afterwards. Reading the play years later, I realized something that felt much more unsettling, that the witches never actually tell Macbeth to kill Duncan, nor force him to become king. They simply plant an idea. From that moment on, every decision Macbeth makes begins revolving around a future that, until he heard it, did not yet exist in his mind.

That is why Macbeth feels strangely similar to reading tarot cards. A tarot reading rarely tells you exactly what will happen. Instead, it offers symbols and possibilities. Once you start believing one interpretation, however, your attention shifts. You notice different details, make different choices, hesitate where you once felt certain, or become confident where you once doubted yourself. The prophecy has not changed reality; it has changed the way you move through it.

This is what psychologists later called a self-fulfilling prophecy: a belief that influences behaviour until the belief itself becomes true. Literature discovered this long before psychology gave it a name. The same idea appears in Harry Potter. Voldemort becomes obsessed with the prophecy foretelling that a child will defeat him. Ironically, it is his attempt to prevent the prophecy that causes it to unfold. Had he ignored it, Harry might have remained an ordinary boy. Instead, Voldemort chooses him, marks him, and ultimately creates the very person capable of destroying him. The prophecy predicts the future only because someone believes it enough to act.

Perhaps that is why I've become less interested in whether prophecies are "real." The more interesting question is whether they need to be. A prophecy does not have to possess supernatural power to change someone's life. Sometimes, all it takes is a sentence that refuses to leave your mind.
