# CoT Spatial Reasoning Degradation

Interactive demo showing that Chain-of-Thought degrades visual spatial reasoning.

**Paper:** "Chain-of-Thought Degrades Visual Spatial Reasoning Capabilities of Multimodal LLMs" (arXiv:2604.16060)

## Hypothesis
CoT prompting causes shortcut learning from textual priors, degrading spatial reasoning performance.

## Key Findings
- CoT degrades performance on 13 spatial benchmarks
- Models hallucinate visual details from text alone
- Need vision-centric reasoning paradigms

## Features
- Spatial grid puzzles
- Mental rotation tasks
- Pattern completion tests
- Compare CoT vs No-CoT performance
