Thinking About How You Think
Metacognition is the trainable habit of observing your own reasoning: ask why you concluded something, calibrate your confidence to the evidence, and keep a daily log of your thinking errors.
- Metacognition is a trainable habit, not a mystical second self.
- Calibrated thinkers match belief strength to the evidence; most people are overconfident.
- A daily error log builds a personal taxonomy of your own mistakes.
The Watcher and the Machine
Every thought you have is produced by a process you rarely inspect. Metacognition begins the moment you turn around and ask: why did I just conclude that? What evidence would have changed my mind? The watcher is not a mystical second self — it is a habit, trainable like any other.
Calibration: Knowing What You Know
A calibrated thinker holds beliefs at the strength the evidence deserves. Practice by attaching a confidence number to your claims for one week, then checking how often the 90%-confident ones were actually right. Most people discover they are systematically overconfident — and that discovery is the beginning of intellectual honesty.
A Daily Practice
End each day with one question: where did my thinking go wrong today, and what pattern does that error belong to? Keep a short log. Within a month you will have a personal taxonomy of your own mistakes — the single most valuable document a thinker can own.
What is metacognition?
Metacognition is thinking about your own thinking — deliberately observing, auditing and steering the reasoning process you normally run on autopilot.
How do you practise metacognition?
Attach a confidence number to your claims and check them, and end each day by logging where your thinking went wrong and what pattern the error belongs to.
