How do I practice perceptual bias?

The most direct way to practice perceptual bias is through a focused exercise: Pick a situation you've already formed an opinion about — a colleague's performance, a technical decision, a relationship pattern. Set a timer for ten minutes. Write down only raw observations: specific behaviors, exact words spoken, measurable outcomes, timestamps. No adjectives that encode judgment ('lazy,' 'brilliant,' 'toxic'). When you catch yourself writing an evaluation, cross it out and replace it with the observable fact underneath. Compare your observation-only account with your original opinion. Note every place where the opinion added information that wasn't actually observed.

Common pitfall: Believing you've suspended judgment when you've actually just moved the judgment underground. You think you're observing, but your 'observations' are pre-filtered — you only notice data that confirms the conclusion you already reached. The tell: your observations always support the same story. Clean observation regularly surprises you.

This practice connects to Phase 5 (Observation Without Judgment) — building it as a repeatable habit compounds over time.
