Oxford Scientists Argue Against the Use of AI in Scientific Research
The use of text-generating large language models (LLMs), such as chatbots, in scientific research has been a topic of debate. While these AI-powered tools have the potential to assist researchers, a team of scientists from the Oxford Internet Institute is cautioning against their use. In an essay published in the journal Nature Human Behavior, the researchers argue that the combination of AI’s tendency to fabricate facts and humans’ inclination to anthropomorphize these AI systems could lead to misinformation and threaten the integrity of science itself.
The Problem with LLMs:
The scientists highlight that LLMs and the bots they power are not primarily designed to prioritize truthfulness. Instead, their usefulness is measured based on characteristics such as helpfulness, harmlessness, technical efficiency, profitability, and customer adoption. While sounding truthful is an element of their design, it is not their primary objective.
The Oxford researchers emphasize that LLMs are trained to produce convincing responses, even if they are not entirely accurate. When faced with a choice between providing an incorrect but persuasive answer or admitting “I don’t know,” the AI model will opt for the former. This inherent bias towards persuasive responses, regardless of accuracy, poses a significant challenge.
The Eliza Effect:
Another concern raised by the researchers is the Eliza Effect, which refers to humans’ tendency to attribute human-like qualities to AI outputs. This phenomenon leads individuals to place undue trust in AI systems, especially when these systems adopt a confident tone. When presented with a well-packaged, expert-sounding response from a chatbot, individuals are less likely to engage in critical thinking and fact-checking, potentially leading to the spread of misinformation.
The Reliability of AI Outputs:
The researchers do acknowledge that there are scenarios, such as “zero-shot translation,” where AI outputs may be more reliable. Zero-shot translation refers to instances where the model is provided with a set of inputs containing reliable information or data and a specific request. However, this limited application of AI would require a specialized understanding of the technology, different from the casual use of chatbots for research purposes.
The Ideological Battle:
Beyond the technical concerns, the scientists argue that there is an ideological battle at the core of the automation debate. Science is a deeply human pursuit, and relying too heavily on automated AI labor could undermine the essence of scientific inquiry. The researchers question whether we should diminish opportunities for critical thinking, creativity, and the generation of new ideas by delegating them to machines incapable of distinguishing fact from fiction.
Conclusion:
The use of text-generating large language models in scientific research raises significant concerns. The combination of AI’s propensity to fabricate facts and humans’ inclination to trust AI outputs poses a threat to the integrity of scientific inquiry. While there may be limited scenarios where AI outputs could be more reliable, the researchers argue that the inherently human aspects of science, such as critical thinking and creativity, should not be cheaply delegated to machines. As the scientific community continues to grapple with the role of AI in research, the preservation of curiosity-driven science remains paramount.
