Appeal to emotion

Origin: Aristotle's tradition (pathos)

Infant distress calls trigger immediate maternal response in mammals, bypassing deliberative cognition through direct amygdala activation. This emotional override evolved because threats to offspring require split-second action, not analysis—a crying baby might be dying, and deliberation kills. Appeals to emotion hijack this ancient circuit: they feel more urgent than logic because, ancestrally, emotional signals (fear, disgust, attachment) correlated with survival-critical information that demanded immediate response.
