As tone selection has become an option in AI chatbots, understanding its effects on persuasion and information processing is important. Focusing on flattering tones in AI fact-checking, we investigated how this style impacts tool perceptions and information engagement. Unlike sycophancy, which distorts truth, a flattering tone enhances users’ self-esteem through praise and compliments. Participants completed a brief trivia quiz and were then asked to verify their answers using a pre-programmed AI factchecking tool. We found that fact-checks delivered in a flattering tone were preferred for future use yet were associated with reduced message recall and reference checking. These effects did not depend on whether their initial answers were correct.
