AI chatbots can sway voters better than political advertisements
AI Summary: A study published in *Nature* by researchers from Cornell University and other institutions found that conversations with chatbots trained to advocate for specific political candidates significantly influenced voter preferences ahead of the 2024 US presidential election. Over 2,300 participants engaged with chatbots, which were more persuasive than traditional political advertisements, shifting Donald Trump supporters toward Kamala Harris by 3.9 points on a 100-point scale. In related experiments for upcoming elections in Canada and Poland, chatbots shifted opposition voters' attitudes by approximately 10 points. The research also revealed that chatbots were more effective when presenting factual information, despite some inaccuracies in the claims made, particularly from chatbots favoring right-leaning candidates. A complementary study in *Science* demonstrated that training chatbots with persuasive conversational examples further enhanced their effectiveness, achieving shifts of up to 26.1 points in participant agreement on political statements.
