People need to feel in control. When you preserve a person’s autonomy by clearly giving them permission to say “No” to your ideas, the emotions calm, the effectiveness of the decisions go up, and the other party can really look at your proposal. They’re allowed to hold it in their hands, to turn it around. And it gives you time to elaborate or pivot in order to convince your counterpart that the change you’re proposing is more advantageous than the status quo.
