How do these acts of expression affect our feelings and opinions? We address this question from an \u201caffordance\u201d perspective, focusing on the effects of both the presence of the expression affordance (cue effects) and users\u2019 actual engagement with it (action effects). We conducted an online experiment (N\u2009=\u2009368) on a news website with thumbs-up\/down and\/or commenting as low-effort and high-effort expression affordances, respectively. Data revealed that the low-effort affordance led to more affective polarization while the high-effort affordance promoted increased interest in deliberation. Merely presenting a commenting cue mitigated affective polarization by increasing perceived interactivity. However, when users engaged the affordance by providing comments, it tended to reinforce pre-existing opinions. These findings have theoretical and practical implications.<\/jats:p>","DOI":"10.1093\/jcmc\/zmac018","type":"journal-article","created":{"date-parts":[[2022,9,15]],"date-time":"2022-09-15T14:17:33Z","timestamp":1663251453000},"source":"Crossref","is-referenced-by-count":26,"title":["Liking versus commenting on online news: effects of expression affordances on political attitudes"],"prefix":"10.1093","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8164-8025","authenticated-orcid":false,"given":"Jinping","family":"Wang","sequence":"first","affiliation":[{"name":"School of Journalism and Communication, The Chinese University of Hong Kong , Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5779-8864","authenticated-orcid":false,"given":"S Shyam","family":"Sundar","sequence":"additional","affiliation":[{"name":"Donald P.
