Overfolding: Dimensional Collapse and Exit Bias in Relational Decision-Making is an exploration/meditation of how human beings navigate relationships under conditions of uncertainty, emotional salience, and incomplete information. It Draws from Cognitive Psychology, Decision Theory, predictive processing, and philosophy, the book examines how people construct emotionally compressed models of intimacy, trust, attachment, and relational risk. Rather than viewing relational suffering as simple irrationality, the book argues that many forms of emotional defensiveness emerge from finite cognitive systems attempting to evaluate environments too unstable and multidimensional to fully compute. Through concepts such as dimensional collapse, overfolding, recursive pessimism, and compressed prediction, it explores why people often withdraw from potentially meaningful relationships long before certainty truly exists.
