The Charlie Line: From Curiosity to Anxiety ——The Neurobiology of Wonder, Prediction Error, and Emotional Value

Curiosity, suspense, and uncertainty neither bring pleasure nor pain, yet they powerfully capture attention and drive exploration. This paper proposes that surprise is an instinctive response of the Wonder Family (the system for processing information gaps), grounded in the Predictive Instinct. When prediction fails, the wonder instinct is triggered—but not all wonder turns into anxiety. The key lies in the Charlie Line: a game between the wonder instinct and the cortical evaluation circuit. The cortex decides either “release” (suppress curiosity, no anxiety) or “pursue” (allow curiosity, activate the Restorative Instinct, anxiety emerges) based on importance and cognitive reward (prediction error). This paper details the neural mechanism of the Charlie Line, its criteria, and extends this framework to commercial “emotional value” products—blind boxes, detective dramas, limited-time flash sales—revealing how they precisely manipulate the Charlie Line and the Restorative Instinct for profit.
