What does it mean that habitual judgments become invisible?

Evaluations you make so often that you no longer notice them are the most dangerous.

Example: A senior engineer reviews a pull request from a junior colleague and immediately thinks 'this is overengineered.' She rejects the PR with terse feedback. Later, reviewing the same pattern from a principal engineer, she calls it 'thoughtful abstraction.' The evaluation was never about the code — it was a habitual judgment about who wrote it. She made the same assessment dozens of times before without noticing the pattern, because the judgment had become invisible through repetition.

Try this: For the next 48 hours, keep a judgment log. Carry a small notebook or open a note on your phone. Every time you catch yourself evaluating something — a person's competence, a piece of work, a decision someone made, your own performance — write down the judgment verbatim and the situation that triggered it. At the end of 48 hours, look for patterns: Which judgments appeared more than once? Which ones felt so automatic you almost missed them? Those are your invisible defaults.
