本书利用Giles和Powesland（1997）的“交际适应论”、Spencer-Oatey（2008）的“和谐管理论”以及Bucholtz和Hall（2005）的“身份与交际论”，研究说话人通过隐含否定策略构建自我职业身份，研究发现：电视争辩性会话中嘉宾使用隐含否定策略构建三种职业身份对：专家身份与非专家身份、群外身份与群内身份、虚假身份与真实身份。本书还揭示了说话人通过隐含否定构建职业身份与人际关系管理，尤其是（不）礼貌的关系：说话人证实对方身份，增强人际和谐，传达人际礼貌；说话人未证实对方社交权（包括平等权与联系权），威胁对方身份面子，导致交际不礼貌意义的传达与评价。最后，本书构建了基于人际语用学研究视角下职业身份建构的机制与模式。
