“O, beware, my lord, of jealousy; It is the green-eyed monster which doth mock the meat it feeds on.”William Shakespeare · Othello, the Moor of Venice · 1603 · Othello, Act 3, Scene 3 (discursul lui Iago)
Jealousy manufactures its own evidence: emotion dictates the reading, and the reading feeds the emotion.
Shakespeare shows how a suspicion, once planted, manufactures its own evidence. Iago does not lie with false facts but with true facts read wrongly: a handkerchief, a hurried departure, a greeting too warm. Othello, given no time to verify, fills the gaps with his own fears, and every innocent gesture of his wife becomes confirmation. The mechanism is a vicious circle of interpretation: emotion dictates the reading, and the reading feeds the emotion. The tragedy comes not from a lie but from the refusal to demand direct proof before judging.
Why it matters When a sudden price or attention shock is read through a ready-made fear, every neutral detail looks like confirmation. The green-eyed monster has a financial and a media variant.
