What is physical environment cognition?

Physical environment cognition is a concept in personal epistemology: Where you work physically changes how you think.

Example: You spend Monday morning writing strategy in a bright, cold conference room with floor-to-ceiling windows. The analysis is sharp but your ideas feel narrow. Tuesday, you work from a dim corner of a coffee shop with warm lighting and ambient noise. Your strategy document barely moves, but you generate three breakthrough ideas for the product roadmap you hadn't thought of in weeks. The difference isn't motivation or discipline. It's that the physical environment activated different cognitive modes — the bright room primed analytical processing, the dim room freed associative thinking.

This concept is part of Phase 9 (Context Sensitivity) in the How to Think curriculum, which builds the epistemic infrastructure for context sensitivity.
