How do I practice social categorization?

The most direct way to practice social categorization is through a focused exercise: Pick a category you use frequently — in your work, your note system, your daily language. It might be 'urgent,' 'technical debt,' 'A-player,' or 'healthy food.' Write down three things: (1) Who created this category? (2) What purpose does it serve? (3) What does it make invisible? If you struggle with question three, you have found a category you have been treating as discovered rather than constructed.

Common pitfall: Treating your own categories as objective features of reality. You will know this is happening when someone proposes an alternative categorization and your first reaction is that they are wrong rather than that they are serving a different purpose. The emotional signature is irritation at reclassification — as if the other person is denying a fact rather than offering a different lens.

This practice connects to Phase 12 (Classification and Typing) — building it as a repeatable habit compounds over time.
