Newswise — A recent publication in the renowned journal Science, authored by prominent researchers hailing from the University of Waterloo, University of Toronto, Yale University, and the University of Pennsylvania, delves into the potential transformation of their work due to artificial intelligence, specifically focusing on large language models (LLMs). The article, released yesterday, explores the implications of LLMs on their respective fields.

Igor Grossmann, a psychology professor at Waterloo, expressed the desire to delve into the adaptation and potential reinvention of social science research practices to effectively utilize the capabilities of AI.

Grossmann and his colleagues highlight the growing potential of large language models, which have been trained on extensive text data, to simulate human-like responses and behaviors. They emphasize that this presents exciting new prospects for testing theories and hypotheses regarding human behavior on a significantly larger scale and with greater speed.

In the traditional realm of social sciences, various methods such as questionnaires, behavioral tests, observational studies, and experiments have been employed to gather data. These methods aim to provide a comprehensive understanding of the characteristics of individuals, groups, cultures, and their interactions. However, the emergence of advanced AI systems has the potential to reshape the landscape of data collection in the social sciences.

According to Grossmann, AI models have the capacity to encompass a wide range of human experiences and perspectives, potentially granting them a greater degree of freedom in generating diverse responses compared to conventional human participant methods. This ability can be beneficial in mitigating concerns related to generalizability in research.

Philip Tetlock, a psychology professor at UPenn, suggests that large language models (LLMs) could potentially replace human participants in data collection processes. He highlights that LLMs have already demonstrated their capability to generate realistic survey responses related to consumer behavior. Tetlock predicts that within the next three years, LLMs will revolutionize human-based forecasting. He believes that in serious policy debates, it will no longer be logical for humans, unassisted by AI, to make probabilistic judgments. He expresses a 90% confidence in this prediction. However, Tetlock acknowledges that the human response to these developments remains uncertain.

While opinions on the feasibility of this application of advanced AI systems vary, studies using simulated participants could be used to generate novel hypotheses that could then be confirmed in human populations.

The researchers caution about potential pitfalls associated with using LLMs in this approach. One such concern is that LLMs are typically trained to exclude socio-cultural biases that are present in real-life humans. While this exclusion helps mitigate biases, it also means that sociologists utilizing AI in this manner may not be able to study those very biases. This limitation should be taken into account when considering the use of AI in social science research.

Professor Dawn Parker, a co-author of the article from the University of Waterloo, emphasizes the need for establishing guidelines regarding the governance of LLMs in research. As the use of LLMs in social science research expands, it becomes crucial to develop clear and transparent protocols to ensure ethical and responsible usage of these models. Establishing such guidelines will help guide researchers in navigating the potential challenges and ethical considerations associated with LLMs in their research endeavors.

Professor Dawn Parker emphasizes the significance of pragmatic considerations related to data quality, fairness, and equitable access to powerful AI systems. To address these concerns, she stresses the importance of ensuring that social science LLMs, like other scientific models, are open-source. This entails making their algorithms and, ideally, the data they are trained on available for scrutiny, testing, and modification by all interested parties. By maintaining transparency and replicability, it becomes possible to ensure that AI-assisted social science research genuinely enhances our understanding of the human experience.
