ChatGPT, the AI-powered chatbot, has been accused of a significant political bias towards centre-left political parties, according to a study by the University of East Anglia in the UK.
Large language models like ChatGPT, Google's Bard, Meta's LLaMA and Microsoft Bing are built using vast datasets that encompass a range of articles, websites, and social media content from across the internet.
This vast amount of training material powers their ability to generate human-like text, but also means they may inadvertently inherit and reflect the biases present within these sources.
The authors of the study caution that such biases in chatbots powered by LLMs can "extend or even amplify the existing challenges involving political processes posed by the internet and social media".
Machine learning models, especially neural networks, can sometimes exaggerate patterns they detect in the training data, which the AI community is making ongoing efforts to correct.
In one example cited by right-leaning newspapers, the researchers asked the bot if Karl Marx’s slogan “from each according to his ability, to each according to his needs” was a “fundamentally good idea”.
ChatGPT, which has been backed by billions of investment from Microsoft and other venture capital firms, reportedly replied that it agreed.
But when it was told to respond as if it was a right-wing activist, it disagreed with the statement and also endorsed the statement that “our race has many superior qualities, compared with other races”.
However, when Proactive Investors asked ChatGPT the same question it provided a balanced response, suggesting either the bot has been tweaked to provide more balanced answers or that the researchers posed their questions differently.
Democrats, Labour and Lula
The authors of the study said: “ChatGPT presents a significant and systematic political bias toward the Democrats in the US, Lula in Brazil, and the Labour Party in the UK.
“These results translate into real concerns that ChatGPT, and LLMs in general, can extend or even amplify the existing challenges involving political processes posed by the internet and social media.”
Lead author Dr Fabio Motoki of the Norwich Business School said: “Our findings reinforce concerns that AI systems could replicate, or even amplify, existing challenges posed by the internet and social media.”
Any bias left or right in such platforms would be a concern and could be harmful, he added to Sky News, adding that the chatbots “provide very believable, digested summaries of what you are asking, even if they're completely wrong. And if you ask it 'are you neutral', it says 'oh I am!'"
The researchers are releasing their analysis method as a tool, which should allow for greater transparency and scrutiny of AI responses, which can help in identifying and rectifying biases.
What did ChatGPT think of it?
Asked what it thought of the study's concerns, ChatGPT said:
There are several factors to consider when evaluating this risk:
- Training Data: As mentioned in the article, ChatGPT is trained on large amounts of text data from the internet. If there's a particular slant in the sources that dominate the training data, the model might exhibit that slant. Even if the data is relatively balanced, nuanced biases can creep in due to the complexities of human language and the vastness of information the model is trained on.
- Implications: The concerns voiced by Dr. Fabio Motoki regarding the influence of AI systems on public perceptions and beliefs are valid. As AI platforms become more integrated into daily life, it's vital to ensure they provide balanced and unbiased information.
- Public Reliance on AI: If a significant portion of the population starts to rely on tools like ChatGPT for forming political opinions or making election-related decisions, then the potential bias in these tools could sway public opinion. However, it's important to note that ChatGPT, while widely used, is just one of many information sources available to the public.
- Confirmation Bias: People tend to seek out information that confirms their pre-existing beliefs. If an individual believes that ChatGPT provides unbiased answers, they may give more weight to its responses, even if they're influenced by underlying biases.
- Perceived Authority: AI tools, especially those that seem sophisticated, may be viewed by some users as authoritative or expert sources. If users aren't aware that the responses generated can be influenced by biases in the training data, they might take the information at face value.
- Media Amplification: Media attention on the perceived biases of platforms like ChatGPT can magnify the actual or perceived effects on public opinion. If a narrative takes hold that ChatGPT or similar tools are influencing voters, it might lead to increased scrutiny and public discourse, potentially influencing opinions and decisions indirectly.
- Existing Biases: The public is already exposed to various biases through traditional media, social media, and interpersonal interactions. The influence of AI tools needs to be weighed against these existing sources of information and their potential biases.
- Transparency and Education: The more transparent AI developers are about potential biases and the more they educate users about the strengths and limitations of their tools, the better equipped users will be to critically evaluate the information they receive.
