Exploring the Nature of Anxiety: The Restorative Instinct and the Origin of Divination

Abstract: Anxiety is commonly regarded as a negative emotion. From the cross‑disciplinary perspective of evolutionary psychology and neuroscience, this paper proposes a different view: anxiety is the subjective experience of the Restorative Instinct — an innate rebound force that automatically activates when any primary instinct (e.g., migration, order, curiosity, attachment) is blocked or suppressed. The Restorative Instinct is a second‑order instinct whose function is to forcibly remove the blockage and allow the original instinct to proceed. The stronger the suppression, the stronger the rebound — this is the core characteristic of anxiety. The paper delineates the neural circuits underlying the Restorative Instinct, including the amygdala (threat detection), BNST (anxiety control center), locus coeruleus (novelty detection and norepinephrine release), and the HPA axis (sustained stress response). It also details the sympathetic‑driven physiological responses during anxiety. Moreover, the paper introduces two activation pathways of the Restorative Instinct:The Charlie Line (a game between the wonder instinct and cortical evaluation) and the Freud Line (a game between individual instincts and social instincts). It explains why most blockages in modern society are unsolvable, leading to chronic anxiety. Finally, taking divination as a cultural example, the paper argues that divination artificially provides a semblance of certainty — temporarily relieving anxiety through a sense of relief (endorphin‑mediated) — thus serving as a culturally invented “tool of the Restorative Instinct.” The paper concludes that anxiety is not an emotion or a mental disorder, but an evolutionarily ancient, ineradicable alarm system. Recognizing this may fundamentally reframe the treatment of anxiety disorders — not by eliminating anxiety, but by identifying the blocked instinct and finding ways to unblock it.
