A Quantitative Survey of Human Perceptual Limits

This report provides a quantitative survey of human perceptual and cognitive capabilities,framed as the 'coverage' of universally available spectra. By synthesizing data across sixcore domains from basic sensory input to abstract mathematical thought we map the narrowwindows through which humans experience reality. Our analysis reveals profoundlimitations, particularly in symbolic and mathematical reasoning. These findings establisha data-driven framework for identifying and prioritizing the critical human augmentationtechnologies required to meet the demands of 2026 and beyond.
