“Ask calibrated questions that start with the words “How” or “What.” By implicitly asking the other party for help, these questions will give your counterpart an illusion of control and will inspire them to speak at length, revealing important information. ■​Don’t ask questions that start with “Why” unless you want your counterpart to defend a goal that serves you. “Why” is always an accusation, in any language. ■​Calibrate your questions to point your counterpart toward solving your problem. This will encourage them to expend their energy on devising a solution.”
