{"pk":49813,"title":"\"Can you tell I used ChatGPT?\" How Perceived AI-Mediation Affects Workplace Email Persuasiveness— A Bayesian Approach","subtitle":null,"abstract":"Large Language Models like ChatGPT are becoming every-day writing partners in the workplace. This study asked: how does simply knowing an email was \"edited by ChatGPT\" affect its persuasiveness and the perceived cred-ibility of the sender? We collected data from 308 profes-sionals using experimental vignettes that simulated realis-tic workplace emails. Some emails were described as en-tirely human-written, while others were labeled as AI-edited, with variations in the sender's reliability (who is sending the message) and strength of the argument (how well the content is constructed). A Bayesian Model of Ar-gumentation provided normative predictions for how reli-ability and argument quality should influence persuasion. We found that when an email was labeled as \"edited by ChatGPT,\" receivers saw it as less persuasive overall. However, AI-mediation did not diminish the relative in-fluence of source reliability and argument quality. In other words, while the AI-edited label reduced overall persua-siveness, it didn't change how recipients inherently evalu-ated credibility. They still adjusted their beliefs primarily based on who sent the message and how strong the argu-ment was. To our knowledge, this is the first study to ap-ply a Bayesian framework to understanding how people process AI-mediated communication.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Psychology; Case-based reasoning; Human-computer interaction; Bayesian modeling"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9jr842z8","frozenauthors":[{"first_name":"Shaked","middle_name":"","last_name":"Karabelnicoff","name_suffix":"","institution":"London School of Economics","department":""},{"first_name":"Jens","middle_name":"Koed","last_name":"Madsen","name_suffix":"","institution":"London School of Economics","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T13:00:00-05:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49813/galley/37775/download/"}]}
