作为一种壮大个人声望、逃避公共讨论的话语样态，胡说八道在社交媒体时代的泛滥威胁着日渐稀薄的沟通理性。本研究通过三项彼此关联的调查或实验（N = 400），依次考察了中国网民对伪深刻话语的接受度及其影响因素、伪深刻媒介话语接受度的领域间差异以及哪些系统性手段能够实时增强人们对胡说八道的识别能力，发现中国网民的胡说八道接受度相对较高，直觉信念和表演性精致降低了其对胡说八道的敏感度，市场经济偏好带来的话语怀疑被规避不确定性而接受伪深刻的文化权威服从机制部分抵消。人们对经验议题、广告和回避型胡说八道的识别能力相对较好，但在特定议题下无法区分机器生成段落与人类作品。研究对运用公共问责写作任务和阻塞厌恶激发降低伪深刻媒介话语接受度的效果和条件进行了探讨，为避免胡说八道污染公共话语的途径提出了对策性建议。

As a discourse strategy to strengthen personal reputation and avoid public discussion, the proliferation of bullshit in the era of social media is threatening the communicative rationality. Through three interrelated surveys or experiments (N = 400), this study examines Chinese netizens’ receptivity of the pseudo-profound media discourse and its influencing factors, the differential receptivity levels of pseudo-profound media discourse in different fields, and what systematic methods can enhance people’s ability to identify bullshit. It is found that Chinese netizens have a relatively high receptivity of bullshit, intuitionistic beliefs and performative refinement reduce their sensitivity to bullshit, and the discursive suspicion brought by the preference for market economy is partially offset by the obedience to cultural authority. People were relatively good at identifying empirical issues, advertising, and evasive bullshit, but could not distinguish machine-generated passages from human work in given issues. This paper discusses the effects and conditions of using public accountability writing task and blocking disgust excitation to reduce the receptivity of pseudo-profound media discourse, and puts forward countermeasures to avoid polluting public discourse with bullshit.
