LESSON 4 · Your Brain's Hidden Shortcuts
Thinking About Thinking
The ultimate cognitive skill is metacognition — thinking about your own thinking. Stepping back from thoughts and evaluating them as an observer.
Metacognition asks: "Why do I believe this? What evidence supports it? What biases might be influencing me?" These questions don't come naturally.
The goal is not perfect rationality — impossible for biological brains running on heuristics. The goal is calibrated confidence, being approximately as certain as evidence warrants.
Your brain's shortcuts are features, not bugs. They come with predictable blind spots. Learn to check their work.
