A person who speaks clearly gives their listeners more freedom to think.

Obscurity concentrates power in the speaker. When an argument is hard to follow, the listener has to spend everything on decoding it and has nothing left for judging whether it is right, so they end up agreeing or deferring rather than thinking. Plain speech hands over the material and invites disagreement, which is precisely why it is riskier for the speaker. Clarity is generous and slightly dangerous at the same time.

Say your next complicated point in the simplest words you can find. Watch whether people start pushing back, and treat that as the method working.
