Vertical Cognitive Depth and Structured Reasoning: A Practical Hypothesis for Robust Behavior Beyond Training Data
Short summary
Modern AI systems fail under distribution shift not from missing knowledge but from poor contradiction handling. Vertical Cognitive Depth (VCD) is a hypothesis that robustness depends on a system's ability to detect, explicitly hold, and transform contradictions between constraints and knowledge. The A11 structured reasoning protocol externally simulates VCD-like behavior by forcing explicit conflict resolution instead of premature convergence.
- •Out-of-distribution failures stem from poor contradiction handling, not missing knowledge
- •VCD hypothesis: robustness depends on detecting and maintaining conflicts between constraints and knowledge
- •A11 reasoning protocol simulates VCD externally by forcing explicit conflict resolution
