Ever run the right test on the wrong categories? It looks rigorous. It isn’t. Buckets are arguments in disguise. Lumpy bins make lumpy answers. Before you analyze, ask: what does each label assume? Do my groups mirror reality… or convenience? Align categories to the mechanism you care about. Then press “go.” Clean categories create clean questions. Clean questions create useful answers. The punchline: your conclusion is only as honest as your bins. Are yours telling the truth?
