Expertise

Expertise is a domain-specific reorganization of how you encode, recognize, and retrieve information.

What makes experts different from novices?

Experts aren’t just “better”, they think differently, offloading work to pattern recognition instead of effortful tracking.

• Encode and organize at a higher level of abstraction
• Recognize meaningful patterns faster
• Retrieve relevant approaches more efficiently

Classic chess-master finding: experts don’t see 30 individual pieces, they see a handful of familiar structures (Chunking at an extreme).

Expertise is narrow

A chess master isn’t better at random board configurations, only meaningful ones. The intuitions come from experience, not general intelligence.
