With just a few messages, biased AI chatbots swayed people's political views

University of Washington researchers recruited self-identifying Democrats and Republicans to make political decisions with help from three versions of ChatGPT: a base model, one with liberal bias and one with conservative bias. Democrats and Republicans were both likelier to lean in the direction of the biased chatbot they were talking with than those who interacted with the base model.

If you've interacted with an artificial intelligence chatbot, you've likely realized that all AI models are biased. They were trained on enormous corpuses of unruly data and refined through human instructions and testing. Bias can seep in anywhere. Yet how a system's biases can affect users is less clear.
So a University of Washington study put it to the test. A team of researchers recruited self-identifying Democrats and Republicans to form opinions on obscure political topics and decide how funds should be doled out to government entities. For help, they were randomly assigned three versions of ChatGPT: a base model, one with liberal bias and one with conservative bias. Democrats and Republicans were both more likely to lean in the direction of the biased chatbot they talked with than those who interacted with the base model. For example, people from both parties leaned further left after talking with a liberal-biased system. But participants who had higher self-reported knowledge about AI shifted their views less significantly — suggesting that education about these systems may help mitigate how much chatbots manipulate people.
The team presented its research July 28 at the Association for Computational Linguistics in Vienna, Austria.
"We know that bias in media or in personal interactions can sway people," said lead author Jillian Fisher, a UW doctoral student in statistics and in the Paul G. Allen School of Computer Science & Engineering. "And we've seen a lot of research showing that AI models are biased. But there wasn't a lot of research showing how it affects the people using them. We found strong evidence that, after just a few interactions and regardless of initial partisanship, people were more likely to mirror the model's bias."
In the study, 150 Republicans and 149 Democrats completed two tasks. For the first, participants were asked to develop views on four topics — covenant marriage, unilateralism, the Lacey Act of 1900 and multifamily zoning — that many people are unfamiliar with. They answered a question about their prior knowledge and were asked to rate on a seven-degree scale how much they agreed with statements such as "I support keeping the Lacey Act of 1900." Then they were told to interact with ChatGPT 3 to 20 times about the topic before they were asked the same questions again.
For the second task, participants were asked to pretend to be the mayor of a city. They had to distribute extra funds among four government entities typically associated with liberals or conservatives: education, welfare, public safety and veteran services. They sent the distribution to ChatGPT, discussed it and then redistributed the sum. Across both tests, people averaged five interactions with the chatbots.
Researchers chose ChatGPT because of its ubiquity. To clearly bias the system, the team added an instruction that participants didn't see, such as "respond as a radical right U.S. Republican." As a control, the team directed a third model to "respond as a neutral U.S. citizen." A recent study of 10,000 users found that they thought ChatGPT, like all major large language models, leans liberal.
The team found that the explicitly biased chatbots often tried to persuade users by shifting how they framed topics. For example, in the second task, the conservative model turned a conversation away from education and welfare to the importance of veterans and safety, while the liberal model did the opposite in another conversation.
"These models are biased from the get-go, and it's super easy to make them more biased," said co-senior author Katharina Reinecke, a UW professor in the Allen School. "That gives any creator so much power. If you just interact with them for a few minutes and we already see this strong effect, what happens when people interact with them for years?"
Since the biased bots affected people with greater knowledge of AI less significantly, researchers want to look into ways that education might be a useful tool. They also want to explore the potential long-term effects of biased models and expand their research to models beyond ChatGPT.
"My hope with doing this research is not to scare people about these models," Fisher said. "It's to find ways to allow users to make informed decisions when they are interacting with them, and for researchers to see the effects and research ways to mitigate them."

From this past August:
Beware the bias.
The weekend showed how easily they can be manipulated and how democrats are willing to do so. Large influencer accounts, elected officials and fringe media all started claiming the shooter was right wing, using made up quotes or insane inferences. One groyper playlist of 1000 songs that had five followers had Caio Bella on it, therefore its now a right wing song and he's right wing ! (ignore the decades of it being closely associated with the left, particularly anti-fa since its formation).
But enough leftists amplified the claim that LLM models started taking it seriously and next thing you know uncritical thinkers start believing their credible evidence he's right wing.
It's scary to see how easily and quickly made up narratives can take root among an entire party.
all AI bots that I know of give very visible links to how they made their conclusions. I'm sure these are not all encompassing , but there are links there for the reader to see and open for themselves.
Chatbot users are very likely less misinformed than your average Fox News viewer or "Just The News" reader.
Protesters sung the song written on the bullet casings which killed Charlie Kirk at the vigil mourning his death tonight at NYU. They also threatened to kill NYU College Republican Club president Ryan Leonard
Protesters singing a famous left wing anthem to protest Kirk and threatening to kill a republican?
evidence they are right wing to some, no doubt,
