How does your mind actually build its map of reality? This chapter explores prediction, grooves, confirmation bias, and the emotional weight of being wrong—laying the groundwork for the skeptical tools ahead. No new tools yet. Just a clearer picture of the brain you're working with.

What is reality? This foundational inquiry explores whether reality is made of matter, mind, relations, or something beyond—all we ever know are our “maps,” never the full terrain. Drawing on the latest audit-based protocols, this paper clarifies leading theories and introduces the Gradient Reality Model (GRM), showing why every claim must be continually warranted, versioned, and tested against empirical challenge. Reality: always the terrain, never just the map.
