A crucial factor for fake news to go viral on social media is that users share such content. Here, we aim to shed light on the sharing behavior of users across human-generated vs. AI-generated fake news. Specifically, we study: (1) What is the perceived veracity of human-generated fake news vs. AI-generated fake news? (2) What is the user's willingness to share human-generated fake news vs. AI-generated fake news on social media? (3) What socio-economic characteristics let users fall for AI-generated fake news? To this end, we conducted a pre-registered, online experiment with N= 988 subjects and 20 fake news from the COVID-19 pandemic generated by GPT-4 vs. humans. Our findings show that AI-generated fake news is perceived as less accurate than human-generated fake news, but both tend to be shared equally. Further, several socio-economic factors explain who falls for AI-generated fake news.<\/jats:p>","DOI":"10.1145\/3687028","type":"journal-article","created":{"date-parts":[[2024,11,8]],"date-time":"2024-11-08T15:52:40Z","timestamp":1731081160000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":32,"title":["Comparing the Willingness to Share for Human-generated vs. AI-generated Fake News"],"prefix":"10.1145","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9740-0905","authenticated-orcid":false,"given":"Amirsiavosh","family":"Bashardoust","sequence":"first","affiliation":[{"name":"University of Lausanne, Lausanne, Vaud, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7856-8729","authenticated-orcid":false,"given":"Stefan","family":"Feuerriegel","sequence":"additional","affiliation":[{"name":"Munich Center for Machine Learning, LMU Munich, Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2699-4723","authenticated-orcid":false,"given":"Yash Raj","family":"Shrestha","sequence":"additional","affiliation":[{"name":"University of Lausanne, Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2024,11,8]]},"reference":[{"key":"e_1_2_2_1_1","volume-title":"Hussaini Garba Dikko, and Agboola Samson","author":"Akinwande Michael Olusegun","year":"2015","unstructured":"Michael Olusegun Akinwande, Hussaini Garba Dikko, and Agboola Samson. 2015.
