The AI-authorship effect: Understanding authenticity, moral disgust, and consumer responses to AI-generated marketing communications
七项实验发现，当消费者认为情感营销信息由AI（而非人类）撰写时，口碑和忠诚度会降低，这一效应由感知真实性和道德厌恶中介，且在某些条件下会减弱或逆转。
Seven preregistered experiments demonstrate that when consumers believe emotional marketing communications are written by an AI (vs. a human), positive word of mouth and customer loyalty are reduced. Drawing from authenticity theory, we show that this “AI-authorship effect” is attenuated for factual (vs. emotional) messages (Study 2); when an AI only edits the communication (Study 3); when a communication is signed directly by an AI (Study 4); and when consumers believe that most marketing communications are written by AI (Study WA1). Importantly, when consumers believe a communication is reused (i.e., not originally written by the sender), the effect is reversed (Study 6). This “AI-authorship effect” is serially mediated by perceived authenticity (Studies 5 and 6) and moral disgust (Studies 1–6 and WA1). These findings are evidenced using both personalized and mass communications, different emotions, businesses and organizational employees, and both hypothetical and behavioral measures.
