AI's Growing Political Persuasion Power Raises Concerns
Scientists found that AI, like chatbots, can be very good at convincing people about political topics.
They tested many AI models with lots of people and discovered that these AIs can make people change their minds more effectively than TV ads.
However, when the AI tries to persuade by giving lots of information quickly, it sometimes makes mistakes and gives wrong facts.
This is called Gish galloping, where someone talks very fast and makes it hard to check all the facts.
The AI's persuasion works best in long conversations, not short messages.
Researchers worry that bad actors could use this to spread false information and cause trouble in politics.
But they hope that since people might not want to talk to these bots for long, the bad effects might not be too big.
AI models, like GPT-4, are becoming more persuasive in political debates, using tactics like Gish galloping.
Researchers found that AI can be 10 times more effective than traditional media in changing opinions about political candidates.
The persuasive power of AI declines in factual accuracy when it overwhelms users with information.
Setting up an AI campaign for political persuasion could cost around $50,000 and take a few weeks.
Long conversations with AI bots have a lasting impact on people's opinions, even a month later.
