Expand your vocabulary in domains you want to think more clearly about. More words mean more conceptual distinctions, which means more nuanced thinking. This is why experts have specialized vocabulary—it enables thoughts laypeople can't easily form.
Pay attention to framing and reframe issues when useful. If someone frames an argument in language that biases toward their position, reframe it in neutral or opposing terms. Controlling language controls thought, so fight for fair framing.
Be suspicious of unnecessarily complex language—it's often hiding simple ideas to make them seem more profound or to exclude outsiders. If you can't explain something simply, you probably don't understand it deeply.
Recognize that translation between languages involves conceptual translation, not just word substitution. Some concepts exist in one language but not others. Some poetry survives translation; some doesn't. This reveals language's role in shaping thought.
