Our job as persuaders is easier than we think. It’s not to get others believing what we say. It’s just to stop them unbelieving. Once we achieve that, the game’s half-won. “Unbelief is the friction that keeps persuasion in check,” Dutton says. “Without it, there’d be no limits.” Giving your counterpart the illusion of control by asking calibrated questions—by asking for help—is one of the most powerful tools for suspending unbelief.
