The persuasive impact of AI chatbots on voters.
The effects found are large but likely also an effect of the design.
Regardless, AI is part of election campaigns now.

AI can influence voters' minds. What does that mean for democracy?
Voters change their opinions after interacting with an AI chatbot – but it seems that AIs rely on facts to influence people

10% of surveyed Dutch citizens told us they are likely to ask AI for election advice. They shouldn't!
This is especially problematic as we know that the people who usually consult advice applications are undecided and are doing so right before casting their vote.

Data we are collecting with @algosoc.org in the Netherlands shows similar and even starker trends and age gaps.
Everyone is using ChatGPT more. But 82% of 18-29 year olds now report having used in the past year whereas a still sizeable but comparatively lower amount of 65+ year olds have (19%).
