Managers trained as advocates combine advocacy with inquiry so the aim becomes finding the best argument rather than winning: when advocating, make reasoning and data explicit and invite challenge and different views; when inquiring, state assumptions as assumptions with their data and ask only when genuinely interested; at an impasse ask what data or logic would change views and design an experiment together; where people hesitate, explore what makes open exchange difficult.
