Distinguish observable data from interpretation

Separate what a camera would record from what you made of it.

Why it works

The first and most foundational error on the ladder is treating interpretations as if they were observations. "She was dismissive" is an interpretation; "she did not respond to the last two emails and cut the meeting short by fifteen minutes" is data. Interpretations can be wrong; data can be checked. Confusing them makes disagreements about interpretations feel like disagreements about facts, which are much harder to resolve.

How to do it

1. When you describe a situation, ask: what would a video camera have captured here?
2. Write the observable events separately from your interpretation of them.
3. Test whether two observers with different priors would see the same "data" or different ones.
4. When in conflict with someone, find the lowest rung you both agree on before discussing interpretation.

Evidence

The distinction between description and evaluation is fundamental in behavioral feedback research and in nonviolent communication frameworks. Reducing evaluative language in conflict situations is associated with reduced defensiveness, consistent with research on the impact of labeled vs. described behavior. (mechanistic)

Perfect separation of observation and interpretation is impossible — all perception is theory-laden at some level. The practice aims for better separation, not pure objectivity.

Common mistake

Believing that because something feels obviously observable, it is — "she was hostile" feels as concrete as "she raised her voice," but the former is a judgment.
