Human cognition exhibits persistent tendencies toward meaning overinterpretation, hypersensitivity to weak signals, and discomfort in the absence of stimuli. These phenomena are commonly treated as psychological biases or evolutionary side effects. This paper presents a structural interpretation of meaning overinterpretation, consciousness, and silence intolerance within the framework of Existence-Quantized Geometric Theory (EQGT). Building on event-biased observation and existence threshold band theory, cognition is analyzed as an adaptive response to environments where non-events and stable background states are fundamentally unobservable. Within this framework, meaning overinterpretation emerges as a survival strategy under asymmetric observability, favoring false positives over false negatives. Silence intolerance is reinterpreted as anxiety induced by informational absence, while consciousness itself is modeled as an internal event-generation mechanism that compensates for external informational sparsity. By situating cognitive phenomena within the same structural constraints governing physical systems, this work bridges physics and philosophy of mind without reductionism, reframing consciousness as a functional necessity rather than a metaphysical anomaly.
